  • Making a Javascript game, Having a little problem with scrolling.

    - by RobertWHurst
    I have a #wrapper div and a #grid div nested inside. currently I can scroll around with this function below. getCursorPos : function(){ // set the empty cursor object var cursor = {}; //get the offset from the left of the grid container var grid //offset loop $(function getCursorPos(){ grid = $('#grid').offset(); setTimeout(getCursorPos, game.loopSpeed); }); //continuosly get the position var that = this; $(document).mousemove(function(e){ //if game mode is menu exit if(game.mode === 'menu'){ return; } // NOTE: this looks a litle over done but don't remove anything // its like this because javascript uses floating points // and so in order to line up to the nearest hunderedth I // had to make the cursor and div position intergers by // muliplying by ten. one the two are added I reduced them // and rounded them. that.x = Math.round(((e.pageX * 10) - (grid.left * 10)) / 10); that.y = Math.round(((e.pageY * 10) - (grid.top * 10)) / 10); }); }, the problem is that the mouse coordinates only update when the mouse moves. is there any way to get the coordinates with out moving the mouse?

  • Android on TabHost little more depth of the problem, there is the hard return key on the treatment.

    - by user365723
    Hello everybody, I have a question on the Android Activity, for example I have a TabHost, and there are included four Activities, the first tab is a search Activity, enter a keyword in the current result of this Activity to return, and in the current Activity display. Is called to display the search results themselves. And after searching several times, and then return to key mobile phone keypad, the display is the result of the last search keyword, I want the press back key to return to the last call of the Activity or TabHost. Should I do? By the way, in a tab in the use of Intent calls a Activity, eg: host.addTab (host.newTabSpec ("friend"). setIndicator ("search") . SetContent (new Intent (this, Search.class))); In this Activity in the need to call another Activity, e.g: startActivity (new Intent (this, Other.class)); Also called another Activity displayed on this tab, but not yet jump out of the show. I ask how you can achieve this?

  • JavaScript and PHP - A little confused on how to work them together.

    - by Doug
    So right now, I'm just using a basic form to check a password. I want it to check the password and basically remain on page.html so I can use JavaScript to alert incorrect password or something. I'm not really sure how to do that. It seems it would bring me to check.php. I'm not too sure on the whole process, any help appreciated! Thanks! Page.html <form action="check.php" method="post"> <input type="password" name="password" /> <input type="submit" value="Submit" /> </form> check.php <?php $password = $_POST['password']; if ( $password != "testing" ) { die(); } ?>

    - by Sanyi
    Hi! I have to make the game „Planarity” in Matlab, for school project. (If you Google it, you can see and play the game in flash). The computer have to randomly put 5 circles in the coordinate system in different positions. After that it must draw lines between them. When the circles are randomly put in the coordinate system the coordinates must be whole numbers. Good example for number one circle: (3,4) ; bad example for number one circle (2.5 ,6.7). Please if Matlab is a childs game to you help me by sending me the source code for this. I really really need help... Please help me, this can be one hour to you, but a life saving thing to me...

  • why does vector.size() read in one line too little?

    - by ace
    when running the following code, the amount of lines will read on less then there actually is (if the input file is main itself, or otherwise) why is this and how can i change that fact (besides for just adding 1)? #include <fstream> #include <iostream> #include <string> #include <vector> using namespace std; int main() { // open text file for input string file_name; cout << "please enter file name: "; cin >> file_name; // associate the input file stream with a text file ifstream infile(file_name.c_str()); // error checking for a valid filename if ( !infile ) { cerr << "Unable to open file " << file_name << " -- quitting!\n"; return( -1 ); } else cout << "\n"; // some data structures to perform the function vector<string> lines_of_text; string textline; // read in text file, line by line while (getline( infile, textline, '\n' )) { // add the new element to the vector lines_of_text.push_back( textline ); // print the 'back' vector element - see the STL documentation cout << "line read: " << lines_of_text.back() << "\n"; } cout<<lines_of_text.size(); return 0; }

  • Tuxedo 11gR1 Released

    - by todd.little
    I've been a little quiet the last several months as the Tuxedo team has been very busy. Today Oracle announced the 11gR1 release of the Tuxedo product family. This release includes updates to Tuxedo, TSAM, and SALT, as well as 3 new products that Oracle is announcing today. These 3 new products are the Oracle Tuxedo Application Runtime for CICS and Batch, Oracle Application Rehosting Workbench, and the Tuxedo JCA Adapter. By providing a CICS equivalent runtime and a rehosting workbench to automate the rehosting of COBOL CICS code, JCL procedures, data definitions, and data, Oracle has significantly lowered the effort and risk to rehost mainframe CICS and Batch applications onto the Tuxedo runtime on open systems. By moving off proprietary legacy mainframes, customers have experienced better performance and achieved a 50-80% lowering of their total cost of ownership. The rehosting tools allow the COBOL business logic to remain unchanged and automate the replacement of CICS statements with calls to Tuxedo. The rehosted code can then run on open systems 'as-is'. Users can still use the same TN3270 interfaces they are used to eliminating the need for retraining. Batch procedures can be run and managed under a JES2 like environment. For the first time, customers have the tools and enterprise class runtime environment to move their key legacy assets off the mainframe and on to distributed open systems whether the application uses 250 MIPS, 25,000 MIPS, or more. More on these exciting new options in additional blog entries.

  • Processing Email in Outlook

    - by Daniel Moth
    A. Why Goal 1 = Help others: Have at most a 24-hour response turnaround to internal (from colleague) emails, typically achieving same day response. Goal 2 = Help projects: Not to implicitly pass/miss an opportunity to have impact on electronic discussions around any project on the radar. Not achieving goals 1 & 2 = Colleagues stop relying on you, drop you off conversations, don't see you as a contributing resource or someone that cares, you are perceived as someone with no peripheral vision. Note this is perfect if all you are doing is cruising at your job, trying to fly under the radar, with no ambitions of having impact beyond your absolute minimum 'day job'. B. DON'T: Leave unread email lurking around Don't: Receive or process all incoming emails in a single folder ('inbox' or 'unread mail'). This is actually possible if you receive a small number of emails (e.g. new to the job, not working at a company like Microsoft). Even so, with (your future) success at any level (company, community) comes large incoming email, so learn to deal with it. With large volumes, it is best to let the system help you by doing some categorization and filtering on your behalf (instead of trying to do that in your head as you process the single folder). See later section on how to achieve this. Don't: Leave emails as 'unread' (or worse: read them, then mark them as unread). Often done by individuals who think they possess super powers ("I can mentally cache and distinguish between the emails I chose not to read, the ones that are actually new, and the ones I decided to revisit in the future; the fact that they all show up the same (bold = unread) does not confuse me"). Interactions with this super-powered individuals typically end up with them saying stuff like "I must have missed that email you are talking about (from 2 weeks ago)" or "I am a bit behind, so I haven't read your email, can you remind me". TIP: The only place where you are "allowed" unread email is in your Deleted Items folder. Don't: Interpret a read email as an email that has been processed. Doing that, means you will always end up with fake unread email (that you have actually read, but haven't dealt with completely so you then marked it as unread) lurking between actual unread email. Another side effect is reading the email and making a 'mental' note to action it, then leaving the email as read, so the only thing left to remind you to carry out the action is… you. You are not super human, you will forget. This is a key distinction. Reading (or even scanning) a new email, means you now know what needs to be done with it, in order for it to be truly considered processed. Truly processing an email is to, for example, write an email of your own (e.g. to reply or forward), or take a non-email related action (e.g. create calendar entry, do something on some website), or read it carefully to gain some knowledge (e.g. it had a spec as an attachment), or keep it around as reference etc. 'Reading' means that you know what to do, not that you have done it. An email that is read is an email that is triaged, not an email that is resolved. Sometimes the thing that needs to be done based on receiving the email, you can (and want) to do immediately after reading the email. That is fine, you read the email and you processed it (typically when it takes no longer than X minutes, where X is your personal tolerance – mine is roughly 2 minutes). Other times, you decide that you don't want to spend X minutes at that moment, so after reading the email you need a quick system for "marking" the email as to be processed later (and you still leave it as 'read' in outlook). See later section for how. C. DO: Use Outlook rules and have multiple folders where incoming email is automatically moved to Outlook email rules are very powerful and easy to configure. Use them to automatically file email into folders. Here are mine (note that if a rule catches an email message then no further rules get processed): "personal" Email is either personal or business related. Almost all personal email goes to my gmail account. The personal emails that end up on my work email account, go to a dedicated folder – that is achieved via a rule that looks at the email's 'From' field. For those that slip through, I use the new Outlook 2010  quick step of "Conversation To Folder" feature to let the slippage only occur once per conversation, and then update my rules. "External" and "ViaBlog" The remaining external emails either come from my blog (rule on the subject line) or are unsolicited (rule on the domain name not being microsoft) and they are filed accordingly. "invites" I may do a separate blog post on calendar management, but suffice to say it should be kept up to date. All invite requests end up in this folder, so that even if mail gets out of control, the calendar can stay under control (only 1 folder to check). I.e. so I can let the organizer know why I won't be attending their meeting (or that I will be). Note: This folder is the only one that shows the total number of items in it, instead of the total unread. "Inbox" The only email that ends up here is email sent TO me and me only. Note that this is also the only email that shows up above the systray icon in the notification toast – all other emails cannot interrupt. "ToMe++" Email where I am on the TO line, but there are other recipients as well (on the TO or CC line). "CC" Email where I am on the CC line. I need to read these, but nobody is expecting a response or action from me so they are not as urgent (and if they are and follow up with me, they'll receive a link to this). "@ XYZ" Emails to aliases that are about projects that I directly work on (and I wasn't on the TO or CC line, of course). Test: these projects are in my commitments that I get measured on at the end of the year. "Z Mass" and subfolders under it per distribution list (DL) Emails to aliases that are about topics that I am interested in, but not that I formally own/contribute to. Test: if I unsubscribed from these aliases, nobody could rightfully complain. "Admin" folder, which resides under "Z Mass" folder Emails to aliases that I was added typically by an admin, e.g. broad emails to the floor/group/org/building/division/company that I am a member of. "BCC" folder, which resides under "Z Mass" Emails where I was not on the TO or the CC line explicitly and the alias it was sent to is not one I explicitly subscribed to (or I have been added to the BCC line, which I briefly touched on in another post). When there are only a few quick minutes to catch up on email, read as much as possible from these folders, in this order: Invites, Inbox, ToMe++. Only when these folders are all read (remember that doesn't mean that each email in them has been fully dealt with), we can move on to the @XYZ and then the CC folders. Only when those are read we can go on to the remaining folders. Note that the typical flow in the "Z Mass" subfolders is to scan subject lines and use the new Ctrl+Delete Outlook 2010 feature to ignore conversations. D. DO: Use Outlook Search folders in combination with categories As you process each folder, when you open a new email (i.e. click on it and read it in the preview pane) the email becomes read and stays read and you have to decide whether: It can take 2 minutes to deal with for good, right now, or It will take longer than 2 minutes, so it needs to be postponed with a clear next step, which is one of ToReply – there may be intermediate action steps, but ultimately someone else needs to receive email about this Action – no email is required, but I need to do something ReadLater – no email is required from the quick scan, but this is too long to fully read now, so it needs to be read it later WaitingFor – the email is informing of an intermediate status and 'promising' a future email update. Need to track. SomedayMaybe – interesting but not important, non-urgent, non-time-bound information. I may want to spend part of one of my weekends reading it. For all these 'next steps' use Outlook categories (right click on the email and assign category, or use shortcut key). Note that I also use category 'WaitingFor' for email that I send where I am expecting a response and need to track it. Create a new search folder for each category (I dragged the search folders into my favorites at the top left of Outlook, above my inboxes). So after the activity of reading/triaging email in the normal folders (where the email arrived) is done, the result is a bunch of emails appearing in the search folders (configure them to show the total items, not the total unread items). To actually process email (that takes more than 2 minutes to deal with) process the search folders, starting with ToReply and Action. E. DO: Get into a Routine Now you have a system in place, get into a routine of using it. Here is how I personally use mine, but this part I keep tweaking: Spend short bursts of time (between meetings, during boring but mandatory meetings and, in general, 2-4 times a day) aiming to have no unread emails (and in the process deal with some emails that take less than 2 minutes). Spend around 30 minutes at the end of each day processing most urgent items in search folders. Spend as long as it takes each Friday (or even the weekend) ensuring there is no unnecessary email baggage carried forward to the following week. F. Other resources Official Outlook help on: Create custom actions rules, Manage e-mail messages with rules, creating a search folder. Video on ignoring conversations (Ctrl+Del). Official blog post on Quick Steps and in particular the Move Conversation to folder. If you've read "Getting Things Done" it is very obvious that my approach to email management is driven by GTD. A very similar approach was described previously by ScottHa (also influenced by GTD), worth reading here. He also described how he sets up 2 outlook rules ('invites' and 'external') which I also use – worth reading that too. Comments about this post welcome at the original blog.

  • dasBlog

    - by Daniel Moth
    Some people like blogging on a site that is completely managed by someone else (e.g. http://wordpress.com/) and others, like me, prefer hosting their own blog at their own domain. In the latter case you need to decide what blog engine to install on your web space to power your blog. There are many free blog engines to choose from (e.g. the one from http://wordpress.org/). If, like me, you want to use a blog engine that is based on the .NET platform you have many choices including BlogEngine.NET, Subtext and the one I picked: dasBlog. In this post I'll describe the steps I took to get going with the open source dasBlog (home page, source page). A. Installing First I installed dasBlog on my local Windows 7 machine where I have IIS7 installed. To install dasBlog, I started by clicking the "Install" button on its web gallery page. After that I went through configuration, theming and adding content as described below. Once I was happy that everything was working correctly on the local machine, I set this up on a hosting service. I went for a Windows IIS7 shared hosting 3 month Economy plan from GoDaddy. The dasBlog site lists a bunch of other hosts. You can read the installation instructions for dasBlog, and with GoDaddy I just had to click one button since it is available as part of their quick-install apps. With GoDaddy I had a previewdns option that allowed me to play around and preview my site before going live. B. Configuring After it was installed (on local machine and/or hosting provider), I followed the obvious steps to create an admin user and logged in. This displays an admin navigation bar with the following options: 1. Navigator Links: I decided I was not going to use this feature. I manage links on the side of my blog manually elsewhere as part of the theme. So, I deleted every entry on this page and ignored it thereafter. 2. Blogroll: Ditto - same comment as for Navigator Links. 3. Content Filters: I did not delete (or add) these, but I did ensure both checkboxes are not checked. I.e. I am not using this feature now, but I may return to it in the future. 4. Activity: This is a read-only view of various statistics. So nothing to configure here, but useful to come back to for complementary statistics to whatever other statistical package you use (e.g. free stats as part of the hosting and I also use feedburner for syndication stats). 5. Cross-posting: I did not need that, so I turned it off via the Configuration Settings discussed next. 6. Configuration Settings: This is where the bulk of the configuration for the blog takes place and they are stored in a single XML file: Site.Config file. There are truly self-explanatory options to pick for Basic Settings, Services Settings and Services to Ping, Syndication Settings (this is where you link to your feedburner name if you have one) and Mail to Weblog Settings (I keep this turned off). There are also "Xml Storage System Settings" (I keep this turned off), "OpenId Settings" (I allow OpenID commenters), "Spammer Settings" (Enable captcha, never show email addresses) and "Comment settings" (Enable comments, don't allow on older posts, don't allow html). There are also Appearance Settings (I checked the "Use Post Title for Permalink", replaced spaces with hyphen and unchecked the "Use Unique Title"). Finally, there are also Notification Settings, but they are a bit of hit and miss in my case, in that I don’t always get the emails (still investigating this). C. Adding Content You can add content via the "Add Entry" link on the admin navigation bar or by configuring the "Mail to Weblog" settings and sending email or, do what I've started doing, use Live Writer (also the team has a blog). Another way to add content is programmatically if, for example, you are migrating content from another blog (and I'll cover that in separate post sharing the code). What you should know is that all blog content (posts and comments) live in XML files in a folder called "content" under your dasBlog installation. D. Theming There is a very good guide about themes for dasBlog, there is also a similar guide with screenshots (scroll down to "So how do I create a theme") and the dasBlog macro reference. When you install dasBlog, there are many themes available; each theme is in its own folder (representing the folder name) under the themes folder. You may have noticed that you can switch between these via the "Appearance Settings" described above (look for the combobox after the Default Theme label). I created my own theme by copy-pasting an existing theme folder, renaming it and then switching to it as the default. I then opened the folder in Visual Studio and hacked around the HTML in the 3 files (itemTemplate, homeTemplate and dayTemplate). These files have a blogtemplate file extension, which I temporarily renamed to HTML as I was editing them. There is no more advice I can offer here as this is a matter of taste and the aforementioned links is all I used. Personally, I had salvaged the CSS (and structure) from my previous blog and wanted to make this one match it as closely as possible - I think I have succeeded. E. If you run into any issue with dasBlog... ...use your favorite search engine to find answers. Many bloggers have been using this engine for a while and have documented issues and workarounds over time. One such example is ScottHa's dasBlog category; another example is therightstuff where I "borrowed" the idea/macro for the outlook-style on-page navigation. If you don't find what you want through searching, try posting a question to the forums. Comments about this post welcome at the original blog.

    Developers of Windows Mobile 6.x (and indeed Windows CE) applications still use the rich .NET Compact Framework 3.5 with Visual Studio 2008 for development. That is still a great platform and the Mobile Development Handbook is still a useful resource (if I may say so myself :-). The release of Windows Phone 7, changes the programming paradigm. The programming model has NETCF in its guts, but the developer uses the Silverlight or XNA APIs (and they can call from one into the other). I thought I'd gather here (for your reference and mine) the top 10 resources for getting started. Windows Phone Developer Home - get the official word and latest announcements. Windows Phone Developer Tools RTW - download the free developer tools (on my machine the installation took 30 minutes, over my existing vanilla Visual Studio 2010 install). Windows Phone 7 Jump Start video training - watch the 12 sessions by Wigley/Miles. Windows Phone 7 Developer Training Kit - work through the labs. Windows Phone RSS tag - channel9 has tons more WP7 videos, stay tuned. Windows Phone 7 in 7 Minutes - watch 20 7-minute videos. Programming Windows Phone 7 - read 11 free chapters from Petzold's eBook. The Windows Phone Developer Blog - subscribe to the official blog. Getting Started with Windows Phone Development - explore all links from the MSDN Library root page.            Silverlight for Windows Phone – another root MSDN library page. If after all that you get your hands dirty and still can't find the answer ask questions at the WP7 development MSDN Forum.   On a personal note, I was pleased to see that the Parallel Stacks debugger window works fine with the WP7 project ;-) Comments about this post welcome at the original blog.

  • Preserving Permalinks

    - by Daniel Moth
    One of the things that gets me on a rant is websites that break permalinks. If you have posted something somewhere and there is a public URL pointing to it, that URL should never ever return a 404. You are breaking all websites that ever linked to you and you are breaking all search engine links to your content (that others will try and follow). It is a pet peeve of mine. So when I had to move my blog, obviously I would preserve the root URL (www.danielmoth.com/Blog/), but I also wanted to preserve every URL my blog has generated over the years. To be clear, our focus here is on the URL formatting, not the content migration which I'll talk about in my next post. In this post, I'll describe my solution first and then what it solves. 1. The IIS7 Rewrite Module and web.config There are a few ways you can map an old URL to a new one (so when requests to the old URL come in, they get redirected to the new one). The new blog engine I use (dasBlog) has built-in functionality to do that (Scott refers to it here). Instead, the way I chose to address the issue was to use the IIS7 rewrite module. The IIS7 rewrite module allows redirecting URLs based on pattern matching, regular expressions and, of course, hardcoded full URLs for things that don't fall into any pattern. You can configure it visually from IIS Manager using a handy dialog that allows testing patterns against input URLs. Here is what mine looked like after configuring a few rules: To learn more about this technology check out this video, the reference page and this overview blog post; all 3 pages have a collection of related resources at the bottom worth checking out too. All the visual configuration ends up in a web.config file at the root folder of your website. If you are on a shared hosting service, probably the only way you can use the Rewrite Module is by directly editing the web.config file. Next, I'll describe the URLs I had to map and how that manifested itself in the web.config file. What I did was create the rules locally using the GUI, and then took the generated web.config file and uploaded it to my live site. You can view my web.config here. 2. Monthly Archives Observe the difference between the way the two blog engines generate this type of URL Blogger: /Blog/2004_07_01_mothblog_archive.html dasBlog: /Blog/default,month,2004-07.aspx In my web.config file, the rule that deals with this is the one named "monthlyarchive_redirect". 3. Categories Observe the difference between the way the two blog engines generate this type of URL Blogger: /Blog/labels/Personal.html dasBlog: /Blog/CategoryView,category,Personal.aspx In my web.config file the rule that deals with this is the one named "category_redirect". 4. Posts Observe the difference between the way the two blog engines generate this type of URL Blogger: /Blog/2004/07/hello-world.html dasBlog: /Blog/Hello-World.aspx In my web.config file the rule that deals with this is the one named "post_redirect". Note: The decision is taken to use dasBlog URLs that do not include the date info (see the description of my Appearance settings). If we included the date info then it would have to include the day part, which blogger did not generate. This makes it impossible to redirect correctly and to have a single permalink for blog posts moving forward. An implication of this decision, is that no two blog posts can have the same title. The tool I will describe in my next post (inelegantly) deals with duplicates, but not with triplicates or higher. 5. Unhandled by a generic rule Unfortunately, the two blog engines use different rules for generating URLs for blog posts. Most of the time the conversion is as simple as the example of the previous section where a post titled "Hello World" generates a URL with the words separated by a hyphen. Some times that is not the case, for example: /Blog/2006/05/medc-wrap-up.html /Blog/MEDC-Wrapup.aspx or /Blog/2005/01/best-of-moth-2004.html /Blog/Best-Of-The-Moth-2004.aspx or /Blog/2004/11/more-windows-mobile-2005-details.html /Blog/More-Windows-Mobile-2005-Details-Emerge.aspx In short, blogger does not add words to the title beyond ~39 characters, it drops some words from the title generation (e.g. a, an, on, the), and it preserve hyphens that appear in the title. For this reason, we need to detect these and explicitly list them for redirects (no regular expression can help here because the full set of rules is not listed anywhere). In my web.config file the rule that deals with this is the one named "Redirect rule1 for FullRedirects" combined with the rewriteMap named "StaticRedirects". Note: The tool I describe in my next post will detect all the URLs that need to be explicitly redirected and will list them in a file ready for you to copy them to your web.config rewriteMap. 6. C# code doing the same as the web.config I wrote some naive code that does the same thing as the web.config: given a string it will return a new string converted according to the 3 rules above. It does not take into account the 4th case where an explicit hard-coded conversion is needed (the tool I present in the next post does take that into account). static string REGEX_post_redirect = "[0-9]{4}/[0-9]{2}/([0-9a-z-]+).html"; static string REGEX_category_redirect = "labels/([_0-9a-z-% ]+).html"; static string REGEX_monthlyarchive_redirect = "([0-9]{4})_([0-9]{2})_[0-9]{2}_mothblog_archive.html"; static string Redirect(string oldUrl) { GroupCollection g; if (RunRegExOnIt(oldUrl, REGEX_post_redirect, 2, out g)) return string.Concat(g[1].Value, ".aspx"); if (RunRegExOnIt(oldUrl, REGEX_category_redirect, 2, out g)) return string.Concat("CategoryView,category,", g[1].Value, ".aspx"); if (RunRegExOnIt(oldUrl, REGEX_monthlyarchive_redirect, 3, out g)) return string.Concat("default,month,", g[1].Value, "-", g[2], ".aspx"); return string.Empty; } static bool RunRegExOnIt(string toRegEx, string pattern, int groupCount, out GroupCollection g) { if (pattern.Length == 0) { g = null; return false; } g = new Regex(pattern, RegexOptions.IgnoreCase | RegexOptions.Compiled).Match(toRegEx).Groups; return (g.Count == groupCount); } Comments about this post welcome at the original blog.

  • Tool to convert blogger.com content to dasBlog

    - by Daniel Moth
    Due to blogger.com dropping FTP support, I've had to move my blog. If you are in a similar situation, this post will help you by showing you the necessary steps to take. Goals No loss on blog posts, comments AND all existing permalinks continue to work (redirect to the correct place). Steps Download the XML files corresponding to your blogger.com content and store them in a folder. Install and configure dasBlog on your local machine. Configure your web.config file (will need updating once you run step 4). Use the tool I describe further down to generate the content and place it at the right place. Test your site locally. Once you are happy, repeat step 2 on your hosting provider of choice. Remember to copy up your dasBlog theme folder if you created one. Copy up the local web.config file and the XML dasBlog content files generated by the tool of step 4. Test your site on the server. Once you are happy, go live (following instructions from your hoster). In my case, I gave the nameservers from my new hoster to my existing domain registrar and they made the switch. Tool (code) At step 4 above I referred to a tool. That is an overstatement, it is simply one 450-line C#code file that you can download here: BloggerToDasBlog.cs. I used this from a .NET 2.0 console app (and I run it under the Visual Studio debugger, i.e. F5) like this: Program.cs. The console app referenced the dasBlog 2.3 ASP.NET Blogging Engine i.e. the newtelligence.DasBlog.Runtime.dll assembly. Let me describe what the code does: Input: A path to a folder where the XML files from the old blogger.com blog reside. It can deal with both types of XML file. A full file path to a file where it creates XML redirect input (as required by the rewriteMap mentioned here). The blog URL. The author's email. The blog author name. A path to an empty folder where the new XML dasBlog content files will get created. The subfolder name used after the domain name in the URL. The 3 reg ex patterns to use. You can use the same as mine, but will need to tweak the monthly_archive rule. Again, to see what values I passed for all the above, see my Program.cs file. Output: It creates dasBlog XML files in the folder specified. It creates those by parsing the old blogger.com XML files that reside in the folder specified. After that is generated, copy it to the "Content" folder under your dasBlog installation. It creates an XML file with a single ignorable root element and a bunch of inner XML elements. You can copy paste these in the web.config file as discussed in this post. Other notes: For each blog post, it detects outgoing links to itself (i.e. to the same blog), and rewrites those to point to the new URLs. So internal links do not rely on the web.config redirects. It deals with duplicate post titles; it does not deal with triplicates and higher. Removes all references to blogger.com (e.g. references to [email protected], the injected hidden footer for statistics that each blog post has and others – see the code). It creates a lot of diagnostic output (in the Output window) and indeed the documentation for the code is in the Debug.WriteLine statements ;) This is not code I will maintain or support – it was a throwaway one-use project that I am sharing here as a starting point for anyone finding themselves in the same boat that I was. Enjoy "as is". Comments about this post welcome at the original blog.

  • Best of "The Moth" 2010

    - by Daniel Moth
    It is the time again (like in 2004, 2005, 2006, 2007, 2008, 2009) to look back at my blog for the past year and identify areas of interest that seem to be more prominent than others. After doing so, representative posts follow in my top 5 list (in random order). 1. This was the year where I had to move for the first time since 2004 my blog engine (blogger.com –> dasBlog), host provider (zen –> godaddy), web server technology and OS (apache on Linux –> IIS on Windows Server). My goal was not to break any permalinks or the look and feel of this website. A series of posts covered how I achieved that goal, culminating in a tool for others to use if they wanted to do the same: Tool to convert blogger.com content to dasBlog. Going forward I aim to be sharing more small code utilities like that one… 2. At work I am known for being fairly responsive on email, and more importantly never dropping email balls on the floor. This is due to my email processing system, which I shared here: Processing Email in Outlook. I will be sharing more tips with regards to making the best of the Office products. 3. There is no doubt in my mind that this is the year people will remember as the one where Microsoft finally fights back in the mobile space. Even though the new platform means my Windows Mobile book sales will dwindle :-), I am ecstatic about Windows Phone 7 both as a consumer and as a developer. On the release day, to get you started I shared the top 10 Windows Phone 7 developer resources. I will be sharing my tips from my experience in writing code for and consuming this new platform… 4. For my HPC developer friends using Visual Studio, I shared Slides and code for MPI Cluster Debugger and also gave you all the links you need for getting started with Dryad and DryadLINQ from MSR. Expect more from me on cluster development in the coming year… 5. Still in the HPC space, but actually also in the game and even mainstream development, the big disruption and opportunity comes in the form of GPGPU and, on the Microsoft platform, (currently) DirectCompute. Expect more from me on gpgpu development in the coming year… Subscribe via the link on the left to stay tuned for 2011… I wish you a very Happy New Year (with whatever definition of happiness works for you)!

  • Outlook 2010 – My Top 9 features

    - by Daniel Moth
    Office 2010 has reached RTM. Here are my favorite Outlook features. Speed. It is faster than previous versions and hangs much less… Ignore Conversation (Ctrl+Del). Not interested in a conversation? Click this button on the new ribbon and you'll never receive another message on that thread (they all go to your Deleted folder). Calendar Preview. When receiving a Meeting Request, before deciding to accept or not you get to see a preview of your calendar for that day and where the new meeting would fit in. See full description on outlook team blog post. Quick Steps. See full description on outlook team blog post. I have created my own quick steps for filing conversations to folders, various pre-populated reply templates, creating calendar invites and creating TODOs from received emails. Search Interface. Many of us knew the magic keywords for making smart searches (e.g. from:Name), but it is great to learn many more through the search tools contextual ribbon tab. Next 7 days. Out of the many enhancements to the Calendar view, my favorite is to be able with  single click to view the next 7 days – that is now my default view. MailTips. See full description on outlook team blog post. The ones I particularly like are when composing a mail to someone that has their Out Of Office reply set, you get to read it before sending the mail (and hence can decide to postpone sending). when composing a mail to a distribution list, a message informs you of the number of recipients. Hopefully, senders will use that as a clue for narrowing down the recipient list or at least verifying that their mail should indeed be sent to so many people. "You are not responding to the latest message in this conversation. Click here to open it.". When composing a reply to a conversation and you have not picked the last message to reply to (don't you hate it when people split threads like that?), this is the inline message you see (under the MailTips area) and if you click on the message it opens the last mail in the conversation so you can reply to that. Rich "Conversation Settings" and in particular "Show Messages from Other Folders". For example, you can see in your inbox not only the message you received but also the reply you sent (it gets pulled in from the Sent folder). Another example: a conversation has been taking place on a distribution list (so your rules filed it to a folder) and they add you on the TO or CC line, so it appears in a different folder; regardless of which folder you open, you are able to see the entire conversation. Note that messages from other folders than the one you are browsing, appear in grey text so you can easily spot them. Reading them in one folder, obviously marks them as read in the other folder… If you haven't yet, when are you making the move to Outlook 2010? Comments about this post welcome at the original blog.

  • "Translator by Moth"

    - by Daniel Moth
    This article serves as the manual for the free Windows Phone 7 app called "Translator by Moth". The app is available from the following link (browse the link on your Window Phone 7 phone, or from your PC with zune software installed): http://social.zune.net/redirect?type=phoneApp&id=bcd09f8e-8211-e011-9264-00237de2db9e   Startup At startup the app makes a connection to the bing Microsoft Translator service to retrieve the available languages, and also which languages offer playback support (two network calls total). It populates with the results the two list pickers ("from" and "to") on the "current" page. If for whatever reason the network call fails, you are informed via a message box, and the app keeps trying to make a connection every few seconds. When it eventually succeeds, the language pickers on the "current" page get updated. Until it succeeds, the language pickers remain blank and hence no new translations are possible. As you can guess, if the Microsoft Translation service add more languages for textual translation (or enables more for playback) the app will automatically pick those up. "current" page The "current" page is the main page of the app with language pickers, translation boxes and the application bar. Language list pickers The "current" page allows you to pick the "from" and "to" languages, which are populated at start time. Until these language get populated with the results of the network calls, they remain empty and disabled. When enabled, tapping on either of them brings up on a full screen popup the list of languages to pick from, formatted as English Name followed by Native Name (when the latter is known). The "to" list, in addition to the language names, indicates which languages have playback support via a * in front of the language name. When making a selection for the "to" language, and if there is text entered for translation, a translation is performed (so there is no need to tap on the "translate" application bar button). Note that both language choices are remembered between different launches of the application.   text for translation The textbox where you enter the translation is always enabled. When there is nothing entered in it, it displays (centered and in italics) text prompting you to enter some text for translation. When you tap on it, the prompt text disappears and it becomes truly empty, waiting for input via the keyboard that automatically pops up. The text you type is left aligned and not in italic font. The keyboard shows suggestions of text as you type. The keyboard can be dismissed either by tapping somewhere else on the screen, or via tapping on the Windows Phone hardware "back" button, or via taping on the "enter" key. In the latter case (tapping on the "enter" key), if there was text entered and if the "from" language is not blank, a translation is performed (so there is no need to tap on the "translate" application bar button). The last text entered is remembered between application launches. translated text The translated text appears below the "to" language (left aligned in normal font). Until a translation is performed, there is a message in that space informing you of what to expect (translation appearing there). When the "current" page is cleared via the "clear" application bar button, the translated text reverts back to the message. Note a subtle point: when a translation has been performed and subsequently you change the "from" language or the text for translation, the translated text remains in place but is now in italic font (attempting to indicate that it may be out of date). In any case, this text is not remembered between application launches. application bar buttons and menus There are 4 application bar buttons and 4 application bar menus. "translate" button takes the text for translation and translates it to the translated text, via a single network call to the bing Microsoft Translator service. If the network call fails, the user is informed via a message box. The button is disabled when there is no "from" language available or when there is not text for translation entered. "play" button takes the translated text and plays it out loud in a native speaker's voice (of the "to" language), via a single network call to the bing Microsoft Translator service. If the network call fails, the user is informed via a message box. The button is disabled when there is no "to" language available or when there is no translated text available. "clear" button clears any user text entered in the text for translation box and any translation present in the translated text box. If both of those are already empty, the button is disabled. It also stops any playback if there is one in flight. "save" button saves the entire translation ("from" language, "to" language, text for translation, and translated text) to the bottom of the "saved" page (described later), and simultaneously switches to the "saved" page. The button is disabled if there is no translation or the translation is not up to date (i.e. one of the elements have been changed). "swap to and from languages" menu swaps around the "from" and "to" languages. It also takes the translated text and inserts it in the text for translation area. The translated text area becomes blank. The menu is disabled when there is no "from" and "to" language info. "send translation via sms" menu takes the translated text and creates an SMS message containing it. The menu is disabled when there is no translation present. "send translation via email" menu takes the translated text and creates an email message containing it (after you choose which email account you want to use). The menu is disabled when there is no translation present. "about" menu shows the "about" page described later. "saved" page The "saved" page is initially empty. You can add translations to it by translating text on the "current" page and then tapping the application bar "save" button. Once a translation appears in the list, you can read it all offline (both the "from" and "to" text). Thus, you can create your own phrasebook list, which is remembered between application launches (it is stored on your device). To listen to the translation, simply tap on it – this is only available for languages that support playback, as indicated by the * in front of them. The sound is retrieved via a single network call to the bing Microsoft Translator service (if it fails an appropriate message is displayed in a message box). Tap and hold on a saved translation to bring up a context menu with 4 items: "move to top" menu moves the selected item to the top of the saved list (and scrolls there so it is still in view) "copy to current" menu takes the "from" and "to" information (language and text), and populates the "current" page with it (switching at the same time to the current page). This allows you to make tweaks to the translation (text or languages) and potentially save it back as a new item. Note that the action makes a copy of the translation, so you are not actually editing the existing saved translation (which remains intact). "delete" menu deletes the selected translation. "delete all" menu deletes all saved translations from the "saved" page – there is no way to get that info back other than re-entering it, so be cautious. Note: Once playback of a translation has been retrieved via a network call, Windows Phone 7 caches the results. What this means is that as long as you play a saved translation once, it is likely that it will be available to you for some time, even when there is no network connection.   "about" page The "about" page provides some textual information (that you can view in the screenshot) including a link to the creator's blog (that you can follow on your Windows Phone 7 device). Use that link to discover the email for any feedback. Other UI design info As you can see in the screenshots above, "Translator by Moth" has been designed from scratch for Windows Phone 7, using the nice pivot control and application bar. It also supports both portrait and landscape orientations, and looks equally good in both the light and the dark theme. Other than the default black and white colors, it uses the user's chosen accent color (which is blue in the screenshot examples above). Feedback and support Please report (via the email on the blog) any bugs you encounter or opportunities for performance improvements and they will be fixed in the next update. Suggestions for new features will be considered, but given that the app is FREE, no promises are made. If you like the app, don't forget to rate "Translator by Moth" on the marketplace.

  • Blogger.com kills FTP

    - by Daniel Moth
    History (you can safely ignore) Back in 2002 I came across some (almost) free Linux/Apache space and set up my first manually-created HTML-based home page, which still exists: http://www.danielmoth.com/. In 2004 I wanted to have a blog that would be hosted on a sub-folder of my domain, and at the same time I did not want to mess with setting up a blog engine myself. I found the perfect solution in blogger.com, which offered a web interface for creating blog posts (and managing the pages' template) and it would then use FTP to upload HTML pages to my space (no server-side programming/installation required at all)! FTP feature dropped by blogger.com Unfortunately, along the way Google purchased blogger.com and a couple of months ago they announced that they decided to kill the FTP feature, and they are forcing customers using that feature to have their content hosted (in an opaque way) on Google's servers. Even though I prefer having my content on my own space, I would have considered moving it to Google's servers if I could host my blog in a sub-folder and preserve my full blog URL: http://www.danielmoth.com/Blog/ (including my home pages being hosted at the root of the domain). Sadly, that is not possible. What now So I decided to move my blog somewhere else. I'll document on the next few posts how I did that (inc. a tool I wrote) in case it helps someone else in the same situation and also as a reminder to me if I need to do something like this again in the future.

  • AutoFit in PowerPoint: Turn it OFF

    - by Daniel Moth
    Once a feature has shipped, it is very hard to eliminate it from the next release. If I was in charge of the PowerPoint product, I would not hesitate for a second to remove the dreadful AutoFit feature. Fortunately, AutoFit can be turned off on a slide-by-slide basis and, even better, globally: go to the PowerPoint "Options" and under "Proofing" find the "AutoCorrect Options…" button which brings up the dialog where you need to uncheck the last two checkboxes (see the screenshot to the right). AutoFit is the ability for the user to keep hitting the Enter key as they type more and more text into a slide and it magically still fits, by shrinking the space between the lines and then the text font size. It is the root of all slide evil. It encourages people to think of a slide as a Word document (which may be your goal, if you are presenting to execs in Microsoft, but that is a different story). AutoFit is the reason you fall asleep in presentations. AutoFit causes too much text to appear on a slide which by extension causes the following: When the slide appears, the text is so small so it is not readable by everyone in the audience. They dismiss the presenter as someone who does not care for them and then they stop paying attention. If the text is readable, but it is too much (hence the AutoFit feature kicked in when the slide was authored), the audience is busy reading the slide and not paying attention to the presenter. Humans can either listen well or read well at the same time, so when they are done reading they now feel that they missed whatever the speaker was saying. So they "switch off" for the rest of the slide until the next slide kicks in, which is the natural point for them to pick up paying attention again. Every slide ends up with different sized text. The less visual consistency between slides, the more your presentation feels unprofessional. You can do better than dismiss the (subconscious) negative effect a deck with inconsistent slides has on an audience. In contrast, the absence of AutoFit Leads to consistency among all slides in a deck with regards to amount of text and size of said text. Ensures the text is readable by everyone in the audience (presuming the PowerPoint template is designed for the room where the presentation is delivered). Encourages the presenter to create slides with the minimum necessary text to help the audience understand the basic structure, flow, and key points of the presentation. The "meat" of the presentation is delivered verbally by the presenter themselves, which is why they are in the room in the first place. Following on from the previous point, the audience can at a quick glance consume the text on the slide when it appears and then concentrate entirely on the presenter and what they have to say. You could argue that everything above has nothing to do with the AutoFit feature and all to do with the advice to keep slide content short. You would be right, but the on-by-default AutoFit feature is the one that stops most people from seeing and embracing that truth. In other words, the slides are the tool that aids the presenter in delivering their message, instead of the presenter being the tool that advances the slides which hold the message. To get there, embrace terse slides: the first step is to turn off this horrible feature (that was probably introduced due to the misuse of this tool within Microsoft). The next steps are described on my next post. Comments about this post welcome at the original blog.

  • Watermark TextBox for Windows Phone

    - by Daniel Moth
    In my Translator by Moth app, in the textbox where the user enters a translation I show a "prompt" for the user that goes away when they tap on it to enter text (and returns if the textbox remains/becomes empty). See screenshot on the right (or download the free app to experience it). Back in June 2006 I had shown how to achieve this for Windows Vista (TextBox prompt), and a month later implemented a pure managed version for both desktop and Windows Mobile: TextBox with Cue Banner. So when I encountered the same need for my WP7 app, the path of least resistance for me was to convert my existing code to work for the phone. Usage: Instead of TextBox, in your xaml use TextBoxWithPrompt. Set the TextPrompt property to the text that you want the user to be prompted with. Use the MyText property to get/set the actual entered text (never use the Text property). Optionally, via properties change the default centered alignment and italic font, for the prompt text. It is that simple! You can grab my class here: TextBoxWithPrompt.cs Note, that there are many alternative (probably better) xaml-based solutions, so search around for those. Like I said, since I had solved this before, it was easier for my scenario to re-use my implementation – this does not represent best practice :-) Comments about this post welcome at the original blog.

  • Microsoft Technical Computing

    - by Daniel Moth
    In the past I have described the team I belong to here at Microsoft (Parallel Computing Platform) in terms of contributing to Visual Studio and related products, e.g. .NET Framework. To be more precise, our team is part of the Technical Computing group, which is still part of the Developer Division. This was officially announced externally earlier this month in an exec email (from Bob Muglia, the president of STB, to which DevDiv belongs). Here is an extract: "… As we build the Technical Computing initiative, we will invest in three core areas: 1. Technical computing to the cloud: Microsoft will play a leading role in bringing technical computing power to scientists, engineers and analysts through the cloud. Existing high- performance computing users will benefit from the ability to augment their on-premises systems with cloud resources that enable ‘just-in-time’ processing. This platform will help ensure processing resources are available whenever they are needed—reliably, consistently and quickly. 2. Simplify parallel development: Today, computers are shipping with more processing power than ever, including multiple cores, but most modern software only uses a small amount of the available processing power. Parallel programs are extremely difficult to write, test and trouble shoot. However, a consistent model for parallel programming can help more developers unlock the tremendous power in today’s modern computers and enable a new generation of technical computing. We are delivering new tools to automate and simplify writing software through parallel processing from the desktop… to the cluster… to the cloud. 3. Develop powerful new technical computing tools and applications: We know scientists, engineers and analysts are pushing common tools (i.e., spreadsheets and databases) to the limits with complex, data-intensive models. They need easy access to more computing power and simplified tools to increase the speed of their work. We are building a platform to do this. Our development efforts will yield new, easy-to-use tools and applications that automate data acquisition, modeling, simulation, visualization, workflow and collaboration. This will allow them to spend more time on their work and less time wrestling with complicated technology. …" Our Parallel Computing Platform team is directly responsible for item #2, and we work very closely with the teams delivering items #1 and #3. At the same time as the exec email, our marketing team unveiled a website with interviews that I invite you to check out: Modeling the World. Comments about this post welcome at the original blog.

  • Word 2010 Navigation Pane and more

    - by Daniel Moth
    I have been using Office 2010 since Beta1 and have not looked back since. I am currently on an internal RC, but will upgrade tomorrow to the RTM version. There are a plethora of new productivity features and for Word 2010 the one that overshadows everything else, IMO, is the Navigation Pane. I could spend time describing it here, but I'll never be able to cover it more thoroughly than what the product team has on their blog post. You enable it via the "Navigation Pane" checkbox in the "Show" group of the "View" tab on the Word ribbon. Even if you have come across this new Word 2010 feature, trust me you will learn something more about it, you will thank me later. Go learn how to make the most of the new Navigation Pane.             As an aside, there are many new benefits in PowerPoint 2010 too, my favorite being support for sections. Not to leave Excel 2010 out, you should check Excel's integration with HPC Server. Comments about this post welcome at the original blog.

  • Slide Creation Checklist

    - by Daniel Moth
    PowerPoint is a great tool for conference (large audience) presentations, which is the context for the advice below. The #1 thing to keep in mind when you create slides (at least for conference sessions), is that they are there to help you remember what you were going to say (the flow and key messages) and for the audience to get a visual reminder of the key points. Slides are not there for the audience to read what you are going to say anyway. If they were, what is the point of you being there? Slides are not holders for complete sentences (unless you are quoting) – use Microsoft Word for that purpose either as a physical handout or as a URL link that you share with the audience. When you dry run your presentation, if you find yourself reading the bullets on your slide, you have missed the point. You have a message to deliver that can be done regardless of your slides – remember that. The focus of your audience should be on you, not the screen. Based on that premise, I have created a checklist that I go over before I start a new deck and also once I think my slides are ready. Turn AutoFit OFF. I cannot stress this enough. For each slide, explicitly pick a slide layout. In my presentations, I only use one Title Slide, Section Header per demo slide, and for the rest of my slides one of the three: Title and Content, Title Only, Blank. Most people that are newbies to PowerPoint, get whatever default layout the New Slide creates for them and then start deleting and adding placeholders to that. You can do better than that (and you'll be glad you did if you also follow item #11 below). Every slide must have an image. Remove all punctuation (e.g. periods, commas) other than exclamation points and question marks (! ?). Don't use color or other formatting (e.g. italics, bold) for text on the slide. Check your animations. Avoid animations that hide elements that were on the slide (instead use a new slide and transition). Ensure that animations that bring new elements in, bring them into white space instead of over other existing elements. A good test is to print the slide and see that it still makes sense even without the animation. Print the deck in black and white choosing the "6 slides per page" option. Can I still read each slide without losing any information? If the answer is "no", go back and fix the slides so the answer becomes "yes". Don't have more than 3 bullet levels/indents. In other words: you type some text on the slide, hit 'Enter', hit 'Tab', type some more text and repeat at most one final time that sequence. Ideally your outer bullets have only level of sub-bullets (i.e. one level of indentation beneath them). Don't have more than 3-5 outer bullets per slide. Space them evenly horizontally, e.g. with blank lines in between. Don't wrap. For each bullet on all slides check: does the text for that bullet wrap to a second line? If it does, change the wording so it doesn't. Or create a terser bullet and make the original long text a sub-bullet of that one (thus decreasing the font size, but still being consistent) and have no wrapping. Use the same consistent fonts (i.e. Font Face, Font Size etc) throughout the deck for each level of bullet. In other words, don't deviate form the PowerPoint template you chose (or that was chosen for you). Go on each slide and hit 'Reset'. 'Reset' is a button on the 'Home' tab of the ribbon or you can find the 'Reset Slide' menu when you right click on a slide on the left 'Slides' list. If your slides can survive doing that without you "fixing" things after the Reset action, you are golden! For each slide ask yourself: if I had to replace this slide with a single sentence that conveys the key message, what would that sentence be? This exercise leads you to merge slides (where the key message is split) or split a slide into many, if there were too many key messages on the slide in the first place. It can also lead you to redesign a slide so the text on it really is just explanation or evidence for the key message you are trying to convey. Get the length right. Is the length of this deck suitable for the time you have been given to present? If not, cut content! It is far better to deliver less in a relaxed, polished engaging, memorable way than to deliver in great haste more content. As a rule of thumb, multiply 2 minutes by the number of slides you have, add the time you need for each demo and check if that add to more than the time you have allotted. If it does, start cutting content – we've all been there and it has to be done. As always, rules and guidelines are there to be bent and even broken some times. Start with the above and on a slide-by-slide basis decide which rules you want to bend. That is smarter than throwing all the rules out from the start, right?

  • AutoFit in PowerPoint: Turn it OFF

    - by Daniel Moth
    Once a feature has shipped, it is very hard to eliminate it from the next release. If I was in charge of the PowerPoint product, I would not hesitate for a second to remove the dreadful AutoFit feature. Fortunately, AutoFit can be turned off on a slide-by-slide basis and, even better, globally: go to the PowerPoint "Options" and under "Proofing" find the "AutoCorrect Options…" button which brings up the dialog where you need to uncheck the last two checkboxes (see the screenshot to the right). AutoFit is the ability for the user to keep hitting the Enter key as they type more and more text into a slide and it magically still fits, by shrinking the space between the lines and then the text font size. It is the root of all slide evil. It encourages people to think of a slide as a Word document (which may be your goal, if you are presenting to execs in Microsoft, but that is a different story). AutoFit is the reason you fall asleep in presentations. AutoFit causes too much text to appear on a slide which by extension causes the following: When the slide appears, the text is so small so it is not readable by everyone in the audience. They dismiss the presenter as someone who does not care for them and then they stop paying attention. If the text is readable, but it is too much (hence the AutoFit feature kicked in when the slide was authored), the audience is busy reading the slide and not paying attention to the presenter. Humans can either listen well or read well at the same time, so when they are done reading they now feel that they missed whatever the speaker was saying. So they "switch off" for the rest of the slide until the next slide kicks in, which is the natural point for them to pick up paying attention again. Every slide ends up with different sized text. The less visual consistency between slides, the more your presentation feels unprofessional. You can do better than dismiss the (subconscious) negative effect a deck with inconsistent slides has on an audience. In contrast, the absence of AutoFit Leads to consistency among all slides in a deck with regards to amount of text and size of said text. Ensures the text is readable by everyone in the audience (presuming the PowerPoint template is designed for the room where the presentation is delivered). Encourages the presenter to create slides with the minimum necessary text to help the audience understand the basic structure, flow, and key points of the presentation. The "meat" of the presentation is delivered verbally by the presenter themselves, which is why they are in the room in the first place. Following on from the previous point, the audience can at a quick glance consume the text on the slide when it appears and then concentrate entirely on the presenter and what they have to say. You could argue that everything above has nothing to do with the AutoFit feature and all to do with the advice to keep slide content short. You would be right, but the on-by-default AutoFit feature is the one that stops most people from seeing and embracing that truth. In other words, the slides are the tool that aids the presenter in delivering their message, instead of the presenter being the tool that advances the slides which hold the message. To get there, embrace terse slides: the first step is to turn off this horrible feature (that was probably introduced due to the misuse of this tool within Microsoft). The next steps are described on my next post. Comments about this post welcome at the original blog.
