• Government Mandates and Programming Languages

  A recent SEC proposal (which, at over 600 pages, I havent read in any detail) includes the following: We are proposing to require the filing of a computer program (the waterfall computer program, as defined in the proposed rule) of the contractual cash flow provisions of the securities in the form of downloadable source code in Python, a commonly used computer programming language that is open source and interpretive. The computer program would be tagged in XML and required to be filed with the Commission as an exhibit. Under our proposal, the filed source code for the computer program, when downloaded and run (by loading it into an open Python session on the investors computer), would be required to allow the user to programmatically input information from the asset data file that we are proposing to require as described above. We believe that, with the waterfall computer program and the asset data file, investors would be better able to conduct their own evaluations of ABS and may be less likely to be dependent on the opinions of credit rating agencies. With respect to any registration statement on Form SF-1 (Section 239.44) or Form SF-3 (Section 239.45) relating to an offering of an asset-backed security that is required to comply with Item 1113(h) of Regulation AB, the Waterfall Computer Program (as defined in Item 1113(h)(1) of Regulation AB) must be written in the Python programming language and able to be downloaded and run on a local computer properly configured with a Python interpreter. The Waterfall Computer Program should be filed in the manner specified in the EDGAR Filer Manual. I dont see how it can be in investors best interests that the SEC demand a particular programming language be used for software related to investment data.  I have a feeling that investors who use computers at all already have software with which they are familiar, and that the vast majority of them are not running an open source scripting language on their machines to do their financial analysis.  In fact, I would wager that most of them are using tools like Excel, and if they really need to script anything, its being done with VBA in Excel. Now, Im not proposing that the SEC should require that the data be provided in Excel format with VBA scripts included so everyone can easily access the data (despite the fact that this would actually be pretty useful generally).  Rather, I think it is ill-advised for a government agency to make recommendations of this nature, period.  If the goal of the recommendation is to ensure that the way things work is codified in a transparent manner, than I can certainly respect that.  It seems to me that this could be accomplished without dictating the technology to use.  To wit: An Excel document could contain all of the data as well as the formulae necessary, and most likely would not require the end-user to install anything on their machine The SEC could simply create a calculator in the cloud such that any/all investors could use a single canonical web-based (or web service based) tool Millions of Java and .NET developers could write their own implementations You can read more about this issue, including the favorable position on it, on Jayanth Varmas blog. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How can a developer realize the full value of his work [closed]

  - by Jubbat

  I, honestly, don't want to work as a developer in a company anymore after all I have seen. I want to continue developing software, yes, but not in the way I see it all around me. And I'm in London, a city that congregates lots of great developers from the whole world, so it shouldn't be a problem of location. So, what are my concerns? First of all, best case scenario: you are paying managers salary out of yours. You are consistently underpaid by making up for the average manager negative net return plus his whole salary. Typical scenario. I am a reasonably good developer with common sense who cares for readable code with attention to basic principles. I have found way too often, overconfident and arrogant developers with a severe lack of common sense. Personally, I don't want to follow TDD or Agile practices like all the cool kids nowadays. I would read about them, form my own opinion and take what I feel is useful, but don't follow it sheepishly. I want to work with people who understand that you have to design good interfaces, you absolutely have to document your code, that readability is at the top of your priorities. Also people who don't have a cargo cult mentality too. For instance, the same person who asked me about design patterns in a job interview, later told me that something like a List of Map of Vector of Map of Set (in Java) is very readable. Why would someone ask me about design patterns if they can't even grasp encapsulation? These kind of things are the norm. I've seen many examples. I've seen worse than that too, from very well paid senior devs, by the way. Every second that you spend working with people with such lack of common sense and clear thinking, you are effectively losing money by being terribly inefficient with your time. Yet, with all these inefficiencies, the average developer earns a high salary. So I tried working on my own then, although I don't like the idea. I prefer healthy exchange of opinions and ideas and task division. I then did a bit of online freelancing for a while but I think working in a sweatshop might be more enjoyable. Also, I studied computer engineering and you are in an environment in which your client will presume you don't have any formal education because there is no way to prove it. Again, you are undervalued. You could try building a product, yes. But, of course, luck is a big factor. I wonder if there is a way to work in something you can do well, software development, and be valued for the quality of your work and be paid accordingly, and where you and only you get fairly paid for the value you generate. I know that what I have written seems somehow unlikely but I strongly feel this way. Hopefully someone will understand me and has already figured this out. I don't think I'm alone in this kind of feeling.

• The five steps of business intelligence adoption: where are you?

  - by Red Gate Software BI Tools Team

  When I was in Orlando and New York last month, I spoke to a lot of business intelligence users. What they told me suggested a path of BI adoption. The user’s place on the path depends on the size and sophistication of their organisation. Step 1: A company with a database of customer transactions will often want to examine particular data, like revenue and unit sales over the last period for each product and territory. To do this, they probably use simple SQL queries or stored procedures to produce data on demand. Step 2: The results from step one are saved in an Excel document, so business users can analyse them with filters or pivot tables. Alternatively, SQL Server Reporting Services (SSRS) might be used to generate a report of the SQL query for display on an intranet page. Step 3: If these queries are run frequently, or business users want to explore data from multiple sources more freely, it may become necessary to create a new database structured for analysis rather than CRUD (create, retrieve, update, and delete). For example, data from more than one system — plus external information — may be incorporated into a data warehouse. This can become ‘one source of truth’ for the business’s operational activities. The warehouse will probably have a simple ‘star’ schema, with fact tables representing the measures to be analysed (e.g. unit sales, revenue) and dimension tables defining how this data is aggregated (e.g. by time, region or product). Reports can be generated from the warehouse with Excel, SSRS or other tools. Step 4: Not too long ago, Microsoft introduced an Excel plug-in, PowerPivot, which allows users to bring larger volumes of data into Excel documents and create links between multiple tables.  These BISM Tabular documents can be created by the database owners or other expert Excel users and viewed by anyone with Excel PowerPivot. Sometimes, business users may use PowerPivot to create reports directly from the primary database, bypassing the need for a data warehouse. This can introduce problems when there are misunderstandings of the database structure or no single ‘source of truth’ for key data. Step 5: Steps three or four are often enough to satisfy business intelligence needs, especially if users are sophisticated enough to work with the warehouse in Excel or SSRS. However, sometimes the relationships between data are too complex or the queries which aggregate across periods, regions etc are too slow. In these cases, it can be necessary to formalise how the data is analysed and pre-build some of the aggregations. To do this, a business intelligence professional will typically use SQL Server Analysis Services (SSAS) to create a multidimensional model — or “cube” — that more simply represents key measures and aggregates them across specified dimensions. Step five is where our tool, SSAS Compare, becomes useful, as it helps review and deploy changes from development to production. For us at Red Gate, the primary value of SSAS Compare is to establish a dialog with BI users, so we can develop a portfolio of products that support creation and deployment across a range of report and model types. For example, PowerPivot and the new BISM Tabular model create a potential customer base for tools that extend beyond BI professionals. We’re interested in learning where people are in this story, so we’ve created a six-question survey to find out. Whether you’re at step one or step five, we’d love to know how you use BI so we can decide how to build tools that solve your problems. So if you have a sixty seconds to spare, tell us on the survey!

• Using HTML5 Today part 3&ndash; Using Polyfills

  - by Steve Albers

  Shims helps when adding semantic tags to older IE browsers, but there is a huge range of other new HTML5 features that having varying support on browsers.  Polyfills are JavaScript code and/or browser plug-ins that can provide older or less featured browsers with API support.  The best polyfills will detect the whether the current browser has native support, and only adds the functionality if necessary.  The Douglas Crockford JSON2.js library is an example of this approach: if the browser already supports the JSON object, nothing changes.  If JSON is not available, the library adds a JSON property in the global object. This approach provides some big benefits: It lets you add great new HTML5 features to your web sites sooner. It lets the developer focus on writing to the up-and-coming standard rather than proprietary APIs. Where most one-off legacy code fixes tends to break down over time, well done polyfills will stop executing over time (as customer browsers natively support the feature) meaning polyfill code may not need to be tested against new browsers since they will execute the native methods instead. Your should also remember that Polyfills represent an entirely separate code path (and sometimes plug-in) that requires testing for support.  Also Polyfills tend to run on older browsers, which often have slower JavaScript performance.  As a result you might find that performance on older browsers is not comparable. When looking for Polyfills you can start by checking the Modernizr GitHub wiki or the HTML5 Please site. For an example of a polyfill consider a page that writes a few geometric shapes on a <canvas> <script src="jquery-1.7.1.min.js"><script> <script> $(document).ready(function () { drawCanvas(); }); function drawCanvas() { var context = $("canvas")[0].getContext('2d'); //background context.fillStyle = "#8B0000"; context.fillRect(5, 5, 300, 100); // emptybox context.strokeStyle = "#B0C4DE"; context.lineWidth = 4; context.strokeRect(20, 15, 80, 80); // circle context.arc(160, 55, 40, 0, Math.PI * 2, false); context.fillStyle = "#4B0082"; context.fill(); </script>   The result is a simple static canvas with a box & a circle:   …to enable this functionality on a pre-canvas browser we can find a polyfill.  A check on html5please.com references  FlashCanvas.  Pull down the zip and extract the files (flashcanvas.js, flash10canvas.swf, etc) to a directory on your site.  Then based on the documentation you need to add a single line to your original HTML file: <!--[if lt IE 9]><script src="flashcanvas.js"></script><![endif]—> …and you have canvas functionality!  The IE conditional comments ensure that the library is only loaded in browsers where it is useful, improving page load & processing time. Like all Polyfills, you should test to verify the functionality matches your expectations across browsers you need to support.  For instance the Flash Canvas home page advertises 70% support of HTML5 Canvas spec tests.

• Get More Value From Your Oracle Premier Support Investment

  - by Get Proactive Customer Adoption Team

  Untitled Document The Return on Investment in Support Training I’m a typical software user. I’ve been using spreadsheets almost daily for the past 10 years or so. I know how to enter simple formulas, format cells, import files, and I can sort and filter. Sometimes I even use a pivot table. I never attended training. I learnt everything I know on the fly. Sometimes it was intuitive and easy, other times I had to spend minutes and even hours searching for a solution. Yet when I see what some other people can do with their spreadsheets, I know I’m utilizing maybe 15% of the functionality. Pity, one day I really have to sign up for training. Why haven’t I done it yet? Ah, you know, I’m a busy person, I have work to do. And if I need to use a feature that I am unfamiliar with, I’ll spend time on it only when I really need it. Now wait. When I recall how much time I spent trying to figure how things work compared to time I spent doing the productive work, I realize it was not insignificant. I’m unable to sum up all the time I spent ‘learning’ on the fly, but I’m sure it’s been days or even weeks. And after all this time, I’ve mastered 15% of its features. If only I had attended training years ago. That investment would have paid back 10 times! Working with My Oracle Support is no different. Our customers typically use simple search, create service requests, and download patches. They think they know how to use My Oracle Support. And they’re right. They know something but often they’re utilizing only a fragment of My Oracle Support’s potential. For the investment that has been made, using only a small subset of the capabilities offered in My Oracle Support leaves value on the table. There is much more available in My Oracle Support. Dozens of diagnostic tools and proactive health checks will keep verifying your Oracle environments against best practices that Oracle gathers every day thanks to our comprehensive knowledge management process. Automated patch recommendations will help prevent known issues, and upgrade planning and more is included in My Oracle Support. Why are you not utilizing all of these best practices, capabilities and tools? Is it because you don’t have time to invest 2-3 hours of your time to learn about the features? Simply because you think you can learn on the fly like I thought I could? Does learning on the fly how to properly use the Service Request escalation process when you already have critical issue sound like a good idea? My advice is: Invest your time now to learn how My Oracle Support can help you prevent issues on your systems. Learn how to find answers faster and resolve problems more efficiently. Understand how to properly complete a service request. Invest in Support training, offered at no additional cost to Oracle Premier Support customers. It will pay back quicker than you think.

• How can I get the data from the json one by one by using javascript/jquery? [on hold]

  - by sandhus

  I have the working code which fetches all the records from the json, but how can I make it available one by one on the click of the button or link? The following code is working to fetch all the records: <!doctype html> <html> <head> <meta charset="utf-8"> <title>jQuery PHP Json Response</title> <style type="text/css"> div { text-align:center; padding:10px; } #msg { width: 500px; margin: 0px auto; } .members { width: 500px ; background-color: beige; } </style> </head> <body> <div id="msg"> <table id="userdata" border="1"> <thead> <th>Email</th> <th>Sex</th> <th>Location</th> <th>Picture</th> <th>audio</th> <th>video</th> </thead> <tbody></tbody> </table> </div> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"> </script> <script type="text/javascript"> $(document).ready(function(){ var url="json.php"; $("#userdata tbody").html(""); $.getJSON(url,function(data){ $.each(data.members, function(i,user){ var tblRow = "<tr>" +"<td>"+user.email+"</td>" +"<td>"+user.sex+"</td>" +"<td>"+user.location+"</td>" +"<td>"+"<img src="+user.image+">"+"</td>" +"<td>"+"<audio src="+user.video+" controls>"+"</td>" +"<td>"+"<video src="+user.video+" controls>"+"</td>" +"</tr>" ; $(tblRow).appendTo("#userdata tbody"); }); }); }); </script> </body> </html> I used the json_encode function in the php file to encode the sql db.

• Upgrade to Xubuntu 13.10 - Saucy Salamander

  As a common 'fashion' it is possible to upgrade an existing installation of Ubuntu or one of its derivates every six months. Of course, you might opt-in for the adventure and directly keep your system always on the latest version (including alphas and betas), or you might like to play safe and stay on the long-term support (LTS) versions which are updated every two years only. As for me, I'd like to jump from release to release on my main desktop machine. And since 17th October Saucy Salamander or also known as Ubuntu 13.10 has been released for general use. The following paragraphs document the steps I went in order to upgrade my system to the recent version. Don't worry about the fact that I'm actually using Xubuntu. It's mainly a flavoured version of Ubuntu running Xfce 4.10 as default X Window manager. Well, I have Gnome and LXDE on the same system... just out of couriosity. Preparing the system Before you think about upgrading you have to ensure that your current system is running on the latest packages. This can be done easily via a terminal like so: $ sudo apt-get update && sudo apt-get -y dist-upgrade --fix-missing Next, we are going to initiate the upgrade itself: $ sudo update-manager As a result the graphical Software Updater should inform you that a newer version of Ubuntu is available for installation. Ubuntu's Software Updater informs you whether an upgrade is available Running the upgrade After clicking 'Upgrade...' you will be presented with information about the new version. Details about Ubuntu 13.10 (Saucy Salamander) Simply continue with the procedure and your system will be analysed for the next steps. Analysing the existing system and preparing the actual upgrade to 13.10 Next, we are at the point of no return. Last confirmation dialog before having a coffee break while your machine is occupied to download the necessary packages. Not the best bandwidth at hand after all... yours might be faster. Are you really sure that you want to start the upgrade? Let's go and have fun! Anyway, bye bye Raring Ringtail and Welcome Saucy Salamander! In case that you added any additional repositories like Medibuntu or PPAs you will be informed that they are going to be disabled during the upgrade and they might require some manual intervention after completion. Ubuntu is playing safe and third party repositories are disabled during the upgrade Well, depending on your internet bandwidth this might take something between a couple of minutes and some hours to download all the packages and then trigger the actual installation process. In my case I left my PC unattended during the night. Time to reboot Finally, it's time to restart your system and see what's going to happen... In my case absolutely nothing unexpected. The system booted the new kernel 3.11.0 as usual and I was greeted by a new login screen. Honestly, 'same' system as before - which is good and I love that fact of consistency - and I can continue to work productively. And also Software Updater confirms that we just had a painless upgrade: System is running Ubuntu 13.10 - Saucy Salamander - and up to date See you in six months again... ;-) Post-scriptum In case that you would to upgrade to the latest development version of Ubuntu, run the following command in a console: $ sudo update-manager -d And repeat all steps as described above.

• Webcast On-Demand: Building Java EE Apps That Scale

  - by jeckels

  With some awesome work by one of our architects, Randy Stafford, we recently completed a webcast on scaling Java EE apps efficiently. Did you miss it? No problem. We have a replay available on-demand for you. Just hit the '+' sign drop-down for access.Topics include: Domain object caching Service response caching Session state caching JSR-107 HotCache and more! Further, we had several interesting questions asked by our audience, and we thought we'd share a sampling of those here for you - just in case you had the same queries yourself. Enjoy! What is the largest Coherence deployment out there? We have seen deployments with over 500 JVMs in the Coherence cluster, and deployments with over 1000 JVMs using the Coherence jar file, in one system. On the management side there is an ecosystem of monitoring tools from Oracle and third parties with dashboards graphing values from Coherence's JMX instrumentation. For lifecycle management we have seen a lot of custom scripting over the years, but we've also integrated closely with WebLogic to leverage its management ecosystem for deploying Coherence-based applications and managing process life cycles. That integration introduces a new Java EE archive type, the Grid Archive or GAR, which embeds in an EAR and can be seen by a WAR in WebLogic. That integration also doesn't require any extra WebLogic licensing if Coherence is licensed. How is Coherence different from a NoSQL Database like MongoDB? Coherence can be considered a NoSQL technology. It pre-dates the NoSQL movement, having been first released in 2001 whereas the term "NoSQL" was coined in 2009. Coherence has a key-value data model primarily but can also be used for document data models. Coherence manages data in memory currently, though disk persistence is in a future release currently in beta testing. Where the data is managed yields a few differences from the most well-known NoSQL products: access latency is faster with Coherence, though well-known NoSQL databases can manage more data. Coherence also has features that well-known NoSQL database lack, such as grid computing, eventing, and data source integration. Finally Coherence has had 15 years of maturation and hardening from usage in mission-critical systems across a variety of industries, particularly financial services. Can I use Coherence for local caching? Yes, you get additional features beyond just a java.util.Map: you get expiration capabilities, size-limitation capabilities, eventing capabilites, etc. Are there APIs available for GoldenGate HotCache? It's mostly a black box. You configure it, and it just puts objects into your caches. However you can treat it as a glass box, and use Coherence event interceptors to enhance its behavior - and there are use cases for that. Are Coherence caches updated transactionally? Coherence provides several mechanisms for concurrency control. If a project insists on full-blown JTA / XA distributed transactions, Coherence caches can participate as resources. But nobody does that because it's a performance and scalability anti-pattern. At finer granularity, Coherence guarantees strict ordering of all operations (reads and writes) against a single cache key if the operations are done using Coherence's "EntryProcessor" feature. And Coherence has a unique feature called "partition-level transactions" which guarantees atomic writes of multiple cache entries (even in different caches) without requiring JTA / XA distributed transaction semantics.

• Best way to process a queue in C# (PDF treatment)

  - by Bartdude

  First of all let me expose what I would like to do : I already dispose of a long-time running webapp developed in ASP.NET (C#) 2.0. In this app, users can upload standard PDF files (text+pics). The app is running in production on a Windows Server 2003 and has a dedicated database server (SQL server 2008) also running Windows Server 2003. I myself am a quite experienced web developer, but never actually programmed anything non-web (or at least nothing serious). I plan on adding a functionality to the webapp for which I would need a jpg snapshot of each page of the PDF. Creating these "thumbnails" isn't the big deal as such, I already do it inside my webapp using ghostscript. I've only done it on 1 page documents for now though, and the new functionality will need to process bigger documents. In order for this process to be transparent aswell for the admins as the final users, I would like to implement some kind of queue to delay the processing of the thumbnails. There again, no problem to create the queue, it will consist of records in a table, with enough info to find the pdf document back. Then I will need to process this queue, and that's were my interrogations start. Obviously the best solution to process it isn't an ASP script or so, so I will have to get out of my known environment. No problem, but I have no idea which direction to go. Therefore, a few questions : What should I develop ? I presumably need something that is "standby" on the server, runs when needed, then returns to idle state until further notice.Should I be looking into Windows service ? Is there another more appropriate type of project ? Depending on the first answer, what will be the approach ? Should I have somehow SQL server "tell" the program/service/... to process the queue, or should I have that program/service/... periodically check the state of the queue and treat new items. In both case, which functionality can I use ? we're not talking about hundreds of PDF a day (max 50 maybe), I can totally afford to treat the queue 1 item at a time. Can you confirm I don't have to look much further on threads and so ? (I found a lot of answers talking about threads in queue treatment, but it looks quite overkill for my needs) Maybe linked to the previous question : what about concurrent call to the program, whatever it is ? Let's suppose it is currently running, and a new record comes in the queue, what should be the behaviour ? I don't need much detailed answers and would already be happy with answers like "You can do the processing with a service, and yes it's possible to have sqlserver on machine A trigger a service start on machine B" or "You have to develop xxx and then use the scheduler to run it every xxx minutes". I don't mind reading articles and so, but I can hardly afford to spend too much time learning stuff to finally realize I went the wrong way for this project, so basically I'm trying to narrow down the scope of matters I need to investigate. Thanks for reading me, I hope I'll find some helping hands on here :-)

• free open-source linux screenshot & ocr tool

  - by Gryllida

  I'm looking for a tool which would be able to capture a screen region, pass it to OCR and put the result into clipboard. "import ppm:- | gocr -i - | xclip -selection c" works, but gocr is unreliable: simple text on a webpage has errors. It is a clear font but the OCR tool always misses "r" and replaces it with underscore. "import ppm:- | ocrad -i - | xclip -selection c" says "ocrad: maxval 255 in ppm "P6" file." tesseract needs an image file and does not accept piping input to it. xfce4-screenshooter does not do OCR. ABBYY Screenshot Reader is proprietary. tessnet2 is freeware running on a proprietary platform. Google Docs can OCR screenshots in a batch. But my data is confidential and better not put online.

• svn 503 error when commit new files

  - by philipp

  I am struggling with a strange error when I try to commit my repository. I have a V-server with webmin installed on it. Via Webmin I installed an svn module, created repositories and everything worked fine until three days ago. Trying to commit brings the following error: Commit failed (details follow): Server sent unexpected return value (503 Service unavailable) in response to PROPFIND request for '/svn/rle/!svn/wrk/a1f963a7-0a33-fa48-bfde-183ea06ab958/RLE/.htaccess' Server sent unexpected return value (503 Service unavailable) in response to PROPFIND request for '/svn/rle/RLE/.htaccess' I google everywhere and found only very few solutions. One indicated that a wrong error document is set, another one dealt about the problem that filenames might cause this error and last but not least a wrong proxy configuration in the local svn config could be the reason. After trying all of the solutions suggested I could not reach anything. Only after a server reboot there was a little difference in the error-message, telling me that the server was not able to move a temp file, because the operation was permitted. So I also controlled the permissions of the svn directory, but also with no success. An svn update than restored the "normal" error from above and nothing changed since then. The only change I made on the server, I guess that this could be the reason why svn does not work anymore, was to install the php5_mysql module for apache via apt-get install php5_mysql. Atg the moment I have totally no idea where I could search. I don't know if the problem is on my server or in my repository and I would be glad to get any hint to solve this. Thanks in advance Greetings philipp error log: [Tue Oct 25 19:23:02 2011] [error] [client 217.50.254.18] Could not create activity /svn/rle/!svn/act/d8dd436f-d014-f047-8e87-01baac46a593.

I think this is part of the repository. So, I just just want to admit that i tried to reach the repository via Browser and i worked, I could see everything, so the error only occurs when I try to commit new files. I also created a second repository and tried to commit files in there, what gave me the same error.

• How to change mouse pointer icon in Xfce Debian 7 Wheezy?

  - by kadaj

  I copied the cursor theme (oxy-neon or Oxygen Neon) to /usr/share/icons and from Applications Menu - Settings - Mouse, I am able to see the new theme. I clicked on it and the pointer doesn't change. However the text typing icon ('I'), busy icon, hand icon, and resize window icons got changed. The pointer icon remains the same, the black Adwaita. I removed the Adwaita folder from the icons folder, and still the mouse pointer doesn't change. Is the pointer theme specified elsewhere? I have no setting under home directory. I tried logging out, restart, restarting xfwm4, but nothing works. I just found that the icon pointer changes when the pointer is inside Firefox, but it's not consistent. It keeps changing when I click menu items. Very weird. Any idea how to fix this? This is the output of running: gsettings list-recursively org.gnome.desktop.interface : ~$ gsettings list-recursively org.gnome.desktop.interface org.gnome.desktop.interface automatic-mnemonics true org.gnome.desktop.interface buttons-have-icons false org.gnome.desktop.interface can-change-accels false org.gnome.desktop.interface clock-format '24h' org.gnome.desktop.interface clock-show-date false org.gnome.desktop.interface clock-show-seconds false org.gnome.desktop.interface cursor-blink true org.gnome.desktop.interface cursor-blink-time 1200 org.gnome.desktop.interface cursor-blink-timeout 10 org.gnome.desktop.interface cursor-size 24 org.gnome.desktop.interface cursor-theme 'Adwaita' org.gnome.desktop.interface document-font-name 'Sans 11' org.gnome.desktop.interface enable-animations true org.gnome.desktop.interface font-name 'Cantarell 11' org.gnome.desktop.interface gtk-color-palette 'black:white:gray50:red:purple:blue:light blue:green:yellow:orange:lavender:brown:goldenrod4:dodger blue:pink:light green:gray10:gray30:gray75:gray90' org.gnome.desktop.interface gtk-color-scheme '' org.gnome.desktop.interface gtk-im-module '' org.gnome.desktop.interface gtk-im-preedit-style 'callback' org.gnome.desktop.interface gtk-im-status-style 'callback' org.gnome.desktop.interface gtk-key-theme 'Default' org.gnome.desktop.interface gtk-theme 'Adwaita' org.gnome.desktop.interface gtk-timeout-initial 200 org.gnome.desktop.interface gtk-timeout-repeat 20 org.gnome.desktop.interface icon-theme 'gnome' org.gnome.desktop.interface menubar-accel 'F10' org.gnome.desktop.interface menubar-detachable false org.gnome.desktop.interface menus-have-icons false org.gnome.desktop.interface menus-have-tearoff false org.gnome.desktop.interface monospace-font-name 'Monospace 11' org.gnome.desktop.interface show-input-method-menu true org.gnome.desktop.interface show-unicode-menu true org.gnome.desktop.interface text-scaling-factor 1.0 org.gnome.desktop.interface toolbar-detachable false org.gnome.desktop.interface toolbar-icons-size 'large' org.gnome.desktop.interface toolbar-style 'both-horiz' org.gnome.desktop.interface toolkit-accessibility false ~$

• Proxying webmin with nginx

  - by TheLQ

  I am attempting to proxy webmin behind nginx for various reasons that are outside the scope of this question. However I've been trying for a while now and can't seem to figure it out and think I'm to the point where I've exhausted all the permutations of the config file I can think of. What I have now: relevant nginx config (commented out options removed, I tried many) # Proxy for webmin location /admin/quackwall-webmin { proxy_pass http://127.0.0.1:10000; # Also tried ending with /admin/quackwall-webmin proxy_set_header Host $host; } /etc/webmin/config - Relevant parts webprefix=/admin/quackwall-webmin webprefixnoredir=1 referer=(nginx domain name) Webmin itself is on the standard ports, listening on all addresses temporarily for debugging. SSL has been disabled for right now. So I make a standard request for the login page. However all the CSS and images are broken, with the standard login page returned for all of the resources. In the webmin miniserv logs I see 127.0.0.1 - - [29/Oct/2012:12:29:00 -0400] "GET /admin/quackwall-webmin/session_login.cgi HTTP/1.0" 401 2453 127.0.0.1 - - [29/Oct/2012:12:29:01 -0400] "GET /admin/quackwall-webmin/unauthenticated/style.css HTTP/1.0" 401 2453 127.0.0.1 - - [29/Oct/2012:12:29:01 -0400] "GET /admin/quackwall-webmin/unauthenticated/sorttable.js HTTP/1.0" 401 2453 127.0.0.1 - - [29/Oct/2012:12:29:01 -0400] "GET /admin/quackwall-webmin/unauthenticated/toggleview.js HTTP/1.0" 401 2453 So all the URL's are returning 401s. Interestingly ngrep seems to show that the requests suceeded on the backend communication between nginx and webmin T 127.0.0.1:58908 -> 127.0.0.1:10000 [AP] POST /admin/quackwall-webmin/session_login.cgi HTTP/1.0..Host: (host)..Connection: close..User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW 64; rv:16.0) Gecko/20100101 Firefox/16.0..Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8..Accept-Language: en-US,en;q=0.5. .Accept-Encoding: gzip, deflate..Referer: http://(host)/admin/quackwall-webmin/session_login.cgi..Cookie: testing=1..Cache-Control: ma x-age=0..Content-Type: application/x-www-form-urlencoded..Content-Length: 41....page=%2F&user=(user)&pass=(pass) T 127.0.0.1:10000 -> 127.0.0.1:58908 [AP] HTTP/1.0 200 Document follows.. Various other permutations of these config options and others show similar results, with the URL sent to webmin by nginx either being /admin/quackwall-webmin/session_login.cgi, /admin/quackwall-webmin//session_login.cgi, and just /session_login.cgi. All give 201 Unauthenticated responses. All requests, even those that somewhat succeed (as in I can actually load the resources of the page) Is changing the webprefix in webmin even supported? What am I doing wrong? What else can I try?

• Basic Auth on DirectoryIndex Only

  - by Brad

  I am trying to configure basic auth for my index file, and only my index file. I have configured it like so: <Files index.htm> Order allow,deny Allow from all AuthType Basic AuthName "Some Auth" AuthUserFile "C:/path/to/my/.htpasswd" Require valid-user </Files> When I visit the page, 401 Authorization Required is returned as expected, but the browser doesn't prompt for the username/password. Some further inspection has revealed that Apache is not sending the WWW-Authenticate header. GET http://myhost/ HTTP/1.1 Host: myhost Connection: keep-alive User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.100 Safari/534.30 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 HTTP/1.1 401 Authorization Required Date: Tue, 21 Jun 2011 21:36:48 GMT Server: Apache/2.2.16 (Win32) Content-Length: 401 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>401 Authorization Required</title> </head><body> <h1>Authorization Required</h1> <p>This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.</p> </body></html> Why is Apache doing this? How can I configure it to send that header appropriately? It is worth noting that this exact same set of directives work fine if I set them for a whole directory. It is only when I configure them to a directory index that they do not work. This is how I know my .htpasswd and such are fine. I am using Apache 2.2 on Windows. On another note, I found this listed as a bug in Apache 1.3. This leads me to believe that this is actually a configuration problem on my end.

• Nginx phpmyadmin redirecting to / instead of /phpmyadmin upon login

• order of operations for environment variables

  - by alyda

  I want to understand how environment variables are set and reset (overridden). I'm running Apache/2.2.24 (Unix) PHP/5.4.14 on a mac . My theory is this: Environment vars can be set in bash, then they can be overwritten with httpd.conf preceding a VirtualHost directive that precedes php.ini, which can then be overwritten by .htaccess (if allowable) and finally by PHP I tried the following: setting environment variable in bash: I added export ENVIRONMENT='local' to my ~/.bashrc file, restarted apache and did not get any output from print_r($_ENV); (in a simple index.php file at the root of my webserver). I also tried putting ENVIRONMENT='local' into /etc/environment, and restarting apache, nothing, as well as /etc/bashrc, restart apache. still nothing. setting environment variable in httpd.conf: I added SetEnv ENVIRONMENT 'local-httpd to the end of my /etc/apache2/httpd.conf file (but before I load other conf files, such as virtual host [Include /private/etc/apache2/other/*.conf]). I now see the variable in the array print_r($_SERVER); but not print_r($_ENV);. setting environment variable in httpd-vhosts.conf: I added SetEnv ENVIRONMENT 'local-vhost to my /etc/apache2/extra/httpd-vhosts.conf file in my generic directive that points to my default document root. I now see the variable has been overwritten (to local-vhost from local-httpd, so I know where the variable is getting set). setting environment variable in php.ini: while searching for a proper place to put my environment variable, I noticed that variables_order = "GPCS" was set to the production value rather than EGPCS. I changed it, restarted my server and found that I was now getting output for print_r($_ENV); but not my expected custom variable. It also appears that I am not able to set a custom variable in this file. Please tell me if I am wrong setting environment variable in .htaccess: I added SetEnv ENVIRONMENT 'local-htaccess'. This worked as expected, overwriting all other values that were set. setting / overwriting environment variable in PHP: if (...) { putenv('ENVIRONMENT=local'); } I'm asking this question because I have a lot of local and remote testing servers, some of which may or may not allow me access to modify httpd, httpd-vhost, php.ini or environment variables. I want to understand what is best for those difference scenarios (shared hosting, heroku, local servers, etc) I obviously don't know how to properly set the environment variable in bash in a way that php can use it, I'd like to know how to do that (as I think Heroku does something similar with heroku config set...)

• Slow Windows Explorer on Windows 7

  - by MadBoy

  I have Laptop with i7 (4 cores), 8GB ram and SSD OCZ Vertex 3 MaxIOPS which in testing that I did just now does 400mb/s+ read/write. However the responsiveness of Windows Explorer is far from being perfect. Opening up Computer, Documents, going into folders is very slow (1-5seconds). I don't have any viruses or spyware and I have tried changing properties to optimize view for General Items. I tried disabling Search Indexer but it made search in Outlook 2010 crawl and didn't bring any other effect. Even double clicking on file takes some time to open things up (like clicking a Word document). I don't have any drives mapped, my computer is not joined to domain. I have multiple VPN connections that I connect to but they all have disabled default gateways. I tried using CC Cleaner or some Windows 7 Tweaks app to disable some things. I am power user using Visual Studio, Tortoise SVN and other developer/administration apps. Any non obvious ideas? Edit: So I've been trying to pinpoint where the issue comes from and it seems that straight after reboot Windows Explorer opens very fast, when I load 3-4 programs (Royal TS, Visual Studio, Outlook) it's noticeably slower and the more programs I have it gets worse. After I start closing programs it starts working better and if I leave 2 open it's fast again. I tried doing some research with DiskMon and other programs from sysinternals but couldn't find anything suspicious. Below are stats during normal usage with a lots of programs open: - Ram usage with a lot of programs open and no swap file (i disabled it for testing): 6.95GB - CPU usage: 15%, none of the cores takes more then 50% (I have VS 2010 open x 4) HD Tune Pro: OCZ-VERTEX3 MI Benchmark Test capacity: full Read transfer rate Transfer Rate Minimum : 363.9 MB/s Transfer Rate Maximum : 505.5 MB/s Transfer Rate Average : Access Time : Burst Rate : CPU Usage : HD Tune Pro: OCZ-VERTEX3 MI File Benchmark Drive C: Transfer rate test File Size: 500 MB Sequential read 484102 KB/s Sequential write 444714 KB/s Random read 7779 IOPS Random write 16888 IOPS Random read (queue depth = 32) 73007 IOPS Random write (queue depth = 32) 69790 IOPS HD Tune Pro: OCZ-VERTEX3 MI Random Access Test capacity: full Read test Transfer size operations / sec avg. access time max. access time avg. speed 512 bytes 3260 IOPS 0.306 ms 2.106 ms 1.592 MB/s 4 KB 4161 IOPS 0.240 ms 2.006 ms 16.256 MB/s 64 KB 2382 IOPS 0.419 ms 2.367 ms 148.934 MB/s 1 MB 449 IOPS 2.225 ms 4.197 ms 449.407 MB/s Random 809 IOPS 1.235 ms 6.551 ms 410.527 MB/s HD Tune Pro: OCZ-VERTEX3 MI Extra Tests Test capacity: full Random seek 3975 IOPS 0.252 ms 1.941 MB/s Random seek 4 KB 4245 IOPS 0.236 ms 16.583 MB/s Butterfly seek 4086 IOPS 0.245 ms 1.995 MB/s Random seek / size 64 KB 3812 IOPS 0.262 ms 58.606 MB/s Random seek / size 8 MB 120 IOPS 8.348 ms 485.737 MB/s Sequential outer 4524 IOPS 0.221 ms 282.721 MB/s Sequential middle 4429 IOPS 0.226 ms 276.818 MB/s Sequential inner 5504 IOPS 0.182 ms 344.000 MB/s Burst rate 4472 IOPS 0.224 ms 279.475 MB/s

• Suggestions for sharing and using data between Ubuntu and Windows 7 dual boot

  - by wizjany

  Note: TL;DR, scroll to bottom for summary. I recently set up my computer for a dual boot between Ubuntu 9.10 and Windows 7. My current drive setup is as follows. | A1 | A2 | | B1 | B2 | B3 | A1: 100 mb, windows 7 "System Reserved" boot partition A2: 230 gb, data section, this one needs to be shared between the operating systems B1: 125 gb, windows 7 OS B2: 123 gb, ubuntu OS B3: 2gb, linux swap space Pretty much i want to have my documents, music, pictures, videos, etc accessible from both operating systems. My first attempt involved making the data (a2) partition NTFS, and moving my home folder from ubuntu to the data partition. However, as I read NTFS does not work nice with permission, and it messed up my home folder. My next idea is one of the following: 1) format the data partition to ext2/3/4 and move my home folder from linux there, and get a driver to read ext partitions in windows 7. The problem with that is that most of the ext drivers/software are not compatible with windows 7 or do not integrate with windows explorer (I really don't want to open a separate software window just to access my data, plus it's probably not compatible with other software.) http://www.fs-driver.org/ looks promising, but I'm not sure how it works with ext4 and windows 7 (not officially supported, when trying in vista compatibility mode, it tells me I need to format the ext drive to use it). My next idea, 2) keep the home folder in ubuntu where it is, but create symlinks for the Documents, Music, etc folders to an NTFS formatted Data (A2) partition, and add those locations to the windows 7 libraries. I'm not totally sure how the permissions would work out, but it should be fine since it's only the documents, music, etc and not the important config files in the rest of /home/user/. Correct me if I'm wrong. Currently, symlinks is my best idea, although i'm not sure how it will work. Any suggestions, additions to my ideas, links, pointers, whatever would be greatly appreciated. Even if it means i should reformat both my drives and repartition (2 250gb drives if you want to suggest a setup for that), I won't be too opposed if that's the best suggestion (I've gone through the format/install/format/reinstall process 5 times over the past 3 days, once more won't hurt me). TL;DR, summary: I have two hard drives. One is partitioned for Ubuntu and Windows 7, the second one I want accessible to both operating systems to store documents, music, pictures, videos, etc. Suggestions on how to set up the data drive please =) P.S. bonus if I can get an apache server document root folder working between the two OS's as well (permissions could become very complicated, so don't worry too much about that) P.P.S. Related question, but data viewing is one way: http://superuser.com/questions/84586/partition-scheme-and-size-for-dual-boot-windows-7-and-ubuntu-9-10-with-separate-p

• Windows Setup could not configure Windows to run on this computer's hardware

  - by Hello71

  The whole installation goes smoothly up to the point of "Completing installation ...". The monitor changes resolution, after which a standard dialog box pops up saying Windows Setup could not configure Windows to run on this computer's hardware Then, in a few seconds, the whole machine powers down. Trying to restart produces the message: STOP: c000021a {Fatal System Error} 0x00000000 (0xc0000001 0x00100448) OR it boots into Setup and comes up with the message: Windows Setup encountered an unexpected error... (This is not the actual error, just paraphrasing) I tried using the OEM restore instead of a regular install, but it fails with the same error. (Even though it worked before...) General specs: HP Pavilion Elite e9262f Intel Core i5-750 Processor ATI Radeon HD 4650 Hitachi HDT721010SLA360 ATA Device 6GB DDR3 RAM SuperMulti DVD Burner with LightScribe Some built-in Wi-Fi module http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01916917 I've tried disconnecting the wireless card and disabling the built-in Ethernet and Firewire via the BIOS, and replacing the wireless keyboard and mouse with wired USB ones. Didn't work. I've also tried changing the SATA controller settings in the BIOS to RAID, AHCI, and IDE, reinstalling each time I changed. Still not working. I think the reason why it is showing the Fatal System Error is because it didn't finish installing before it errored out and shut down, so the system is left in an inconsistent state. I've tried 3 different copies (including the OEM restore) of Windows 7 now, and they're all failing at the same point, with the same error message. I've tried to install Windows 7 maybe 10 times already, with the exact same error message at the exact same location. Hm... Interestingly, the 32-bit version of Windows 7 works, but the 64-bit version doesn't. Perhaps it was a badly burned disk? Reburning the 64-bit version still comes up with the same error. Here's a picture of the side of the case that clearly says it came with Windows 7 64-bit, along with the model number and CPU. sudo fdisk -l: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009896f Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 7 HPFS/NTFS /dev/sda2 14 94119 755906445 7 HPFS/NTFS /dev/sda3 119922 121602 13492224 7 HPFS/NTFS /dev/sda4 94120 119922 207257740+ 5 Extended /dev/sda5 119527 119922 3170769 82 Linux swap / Solaris /dev/sda6 107174 119526 99225441 83 Linux /dev/sda7 94120 107173 104856192 7 HPFS/NTFS Partition table entries are not in disk order

• How to configure Transparent IP Address Sharing (TAS) on a Mediatrix 4102 with DGW 2.0 firmware?

  - by Pascal Bourque

  I am making the switch to VoIP. I chose voip.ms as my service provider and Mediatrix 4102 as my ATA. One reason why I chose the Mediatrix over other popular consumer ATAs is that it's supposed to be easy to place it in front of the router, so it can give priority to its own upstream traffic over the home network's upstream traffic. This is supposed to work transparently, with the ATA and router sharing the same public IP address (the one obtained from the modem). They call this feaure Transparent IP Address Sharing, or TAS. Their promotional brochure describes it like this: The Mediatrix 4102 also uses its innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow the PC (or router) connected to the second Ethernet port to have the same public IP address, eliminating the need for private IP addresses or address translations. I am interested by this feature because my router, an Apple Time Capsule, doesn't support QoS and cannot give priority to the voice packets if the ATA is behind the router. However, after hours of searching the web, reading the documentation, and good ol' trial and error, I haven't been able to configure the Mediatrix to run in this mode. Then I found a version of the manual that looks like it was for a previous version of the firmware (SIP), where there is an entire section dedicated to configuring TAS (starting at page 209). But my Mediatrix comes with the DGW 2.0 firmware, whose documentation does not mention TAS at all. So I tried to follow the TAS setup instructions from the SIP documentation and apply them to my DGW firmware, using the Variable Mapping Between SIP v5.0 and DGW v2.0 document as a reference, but no success. Some required SIP variables don't have an equivalent in DGW. So it looks like the DGW firmware does not support TAS at all, or if it does they are not doing anything to help us set it up. So right now, the Mediatrix is behind the router and VoIP works perfectly except when my upstream bandwidth is saturated. My questions are: Is downgrading to SIP firmware the only way to have my Mediatrix 4102 run in TAS mode? If not, anybody knows how to setup TAS on the DGW firmware? Is TAS mode the only way to give priority to the voice packets if I want to keep my current router (Apple Time Capsule)? Thanks!

• grep simply fails when used on a few files

  - by Reid

  I've been trying for about the past 30 minutes to get this to work properly. grep is not exactly the most difficult thing to use, so I'm somewhat baffled as to why this won't work. The files I'm trying to use grep on are simple XHTML log files. Their names are in the format [email protected], though I don't think that should matter, and inside is simple XHTML. I copied one such log file to be testfile so you can see the output of some commands and why it's baffling to me: [~/.chatlogs_windows/dec] > whoami reid [~/.chatlogs_windows/dec] > type grep grep is /bin/grep [~/.chatlogs_windows/dec] > uname -a Linux reid-pc 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux [~/.chatlogs_windows/dec] > head -1 /etc/issue Linux Mint 10 Julia [~/.chatlogs_windows/dec] > ls -Alh | grep testfile -rw-r--r-- 1 reid reid 63K 2011-01-10 12:45 testfile [~/.chatlogs_windows/dec] > tail -3 testfile </body> </html> [~/.chatlogs_windows/dec] > file testfile testfile: XML document text [~/.chatlogs_windows/dec] > grep html testfile [~/.chatlogs_windows/dec] > grep body testfile [~/.chatlogs_windows/dec] > grep "</html>" testfile [~/.chatlogs_windows/dec] > grep "</body>" testfile [~/.chatlogs_windows/dec] > cat testfile | grep html [~/.chatlogs_windows/dec] > cat testfile | wc -l 231 [~/.chatlogs_windows/dec] > cat testfile | tail -3 </body> </html> [~/.chatlogs_windows/dec] > chmod a+rw testfile && ls -Alh | grep testfile -rw-rw-rw- 1 reid reid 63K 2011-01-10 12:45 testfile [~/.chatlogs_windows/dec] > grep html testfile That's what I'm attempting to do. I want to just use grep -ri query . in ~/.chatlogs_windows, which normally works perfectly for me... but for some reason, it completely fails at going through these files. If it matters, I copied these files off of my Windows 7 partition. But I chown'd them and gave myself all the appropriate permissions, and other programs (like cat) seem to read them just fine. I also copied testfile to testfile_unix and converted the line endings and tried that, but it didn't work either. I'm using zsh, but I tried it on bash and that failed too. Also, grep works normally: I tried it out on my documents folder and it worked flawlessly. If you need any more information, just let me know. I tried googling around, but I found no reason for grep to simply not work. Thanks in advance.
