• Resource Graphs in top panel?

  - by Jeff Welling

  I'm running Gnome Classic in Ubuntu 11.10 and in previous versions of Ubuntu it was fairly easy to get resource graphs to appear in the top menu, but now the regular way of getting said graphs in the top menu bar don't work (right clicking on the top menu produces no result unless you click on an icon, eg sound, wifi, or battery indicators). Is it not possible to get resource graphs in the top menu bar in Gnome Classic on Ubuntu 11.10? If not Gnome Classic, is it possible in KDE? I've tried googling but the only results I'm getting are related to adding the panel, which I can't do because I can't right click on the top menu. Thanks in advance.

• XSLT is not the solution you're looking for

  - by Jeff

  I was very relieved to see that Umbraco is ditching XSLT as a rendering mechanism in the forthcoming v5. Thank God for that. After working in this business for a very long time, I can't think of any other technology that has been inappropriately used, time after time, and without any compelling reason.The place I remember seeing it the most was during my time at Insurance.com. We used it, mostly, for two reasons. The first and justifiable reason was that it tweaked data for messaging to the various insurance carriers. While they all shared a "standard" for insurance quoting, they all had their little nuances we had to accommodate, so XSLT made sense. The other thing we used it for was rendering in the interview app. In other words, when we showed you some fancy UI, we'd often ditch the control rendering and straight HTML and use XSLT. I hated it.There just hasn't been a technology hammer that made every problem look like a nail (or however that metaphor goes) the way XSLT has. Imagine my horror the first week at Microsoft, when my team assumed control of the MSDN/TechNet forums, and we saw a mess of XSLT for some parts of it. I don't have to tell you that we ripped that stuff out pretty quickly. I can't even tell you how many performance problems went away as we started to rip it out.XSLT is not your friend. It has a place in the world, but that place is tweaking XML, not rendering UI.

• Unknown CSS font-family oddity with IE7-10 on Win Vista-8

  - by Jeff

  I am seeing the following "oddity" with IE7-10 on Win Vista-8: When declaring font-family: serif; I am seeing an old bitmapped serif font that I can't identify (see screenshot below) instead of the expected font Times New Roman. I know it's an old bitmapped font because it displays aliased, without any font smoothing, with IE7-10 on Win Vista-8 (just like Courier on every version of Win). Screenshot: I would like to know (1) can anyone else confirm my research and (2) BONUS: which font is IE displaying? Notes: IE6 and IE7 on Win XP displays Times New Roman, as they should. It doesn't matter if font-family: serif; is declared in an external stylesheet or inline on the element. Quoting the CSS attribute makes no difference. Adding "Unkown Font" to the stack also makes no difference. New Screenshot: The answer from Jukka below is correct. Here is a new screenshot with Batang (not BatangChe) to illustrate. Hope this helps someone.

• Is meta description still relevant?

  - by Jeff Atwood

  I received this bit of advice about the meta description tag recently: Meta descriptions are used by Google probably 80% of the time for the snippet. They don’t help with rankings but you should probably use them. You could just auto generate them from the first part of the question. The description tag exists in the header, like so: <meta name="Description" content="A brief summary of the content on the page."> I'm not sure why we would need this field, as Google seems perfectly capable of showing the relevant search terms in context in the search result pages, like so (I searched for c# list performance): In other words, where would a meta description summary improve these results? We want the page to show context around the actual search hits, not a random summary we inserted! Google Webmaster Central has this advice: For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions are more difficult. In the latter case, though, programmatic generation of the descriptions can be appropriate and is encouraged -- just make sure that your descriptions are not "spammy." Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation. I'm struggling to think of any scenario when I would want the Google-generated summary, that is, actual context from the page for the search terms, to be replaced by a hard-coded meta description summary of the question itself.

• Addressing a variable in VB

  - by Jeff

  Why doesn't Visual Basic.NET have the addressof operator like C#? In C#, one can int i = 123; int* addr = &i; But VB has no equivalent counter part. It seems like it should be important. UPDATE Since there's some interest, Im copying my response to Strilanc below. The case I ran into didnt necessitate pointers by any means, but I was trying to trouble shoot a unit test that was failing and there was some confusion over whether or not an object being used at one point in the stack was the same object as an object several methods away.

• Ubuntu One Sync as a File Backup Solution?

  - by Jeff

  I was hoping to utilize Ubuntu One and in particular, the syncing feature within Ubuntu One to provide offsite backup for some of my files. My intention was to mark any of my folders that have important files as 'folders to synchronize' to Ubuntu One. It works great in that whenever an important file is placed in the folder, the file is copied up to Ubuntu One (hence creating a backup). However, if any of these important files are lost or accidently deleted from my computer then due to the synchronization it is also immediately deleted from Ubuntu One. This approach does not work very well to provide backup. On one hand I really like the automatic way in which the synch feature will upload any of my important files to Ubuntu One but on the other hand if I lose the file on my computer it will likely be taken off of the cloud as well (via synchronization). What approach are others taking to backup their important files to Ubuntu One? I didn't want to have to manually upload my important files to Ubuntu One and remember to upload other important files as they are created on my computer. Your thoughts and suggestions are greatly appreciated.

EDIT wow, check out the crazy similarities between my post and this one: (the solution didn't solve my issue) http://superuser.com/questions/56450/why-would-sound-suddenly-stop-working-on-windows-7/92957#92957

• Use virtual pageviews for all goal tracking

  - by Jeff Wu

  I'm new to Google Analytics and I'm wondering if it would be cleaner to user virtual pageviews for all the goal tracking on my website instead of using a mix of regular page views and virtual pageviews. I know in most cases this is just semantics but there are multiple pages where the same goal can be achieved and I think it would be cleaner just to fire the same virtual pageview instead of having two different goal pages. Will this model also give developers more flexibility when they do development? I know we are moving to a CMS and urls can get hairy, so I think this might be a good way to make analytics portion of the site "future proof". Any thoughts are appreciated! Thanks.

• Tidbits of goodness - Podcasts, REST, JSON

  - by jeff.x.davies

  I've been quiet for a while, busy with a variety of projects. I did want to let you all know about a couple of things going on. First, I have been participating in architectural podcasts with Bob Rhubart. If you are interested in hearing these short (about 10 minutes each) recordings where a group of us discuss enterprise architecture and its future, check out http://blogs.oracle.com/archbeat/2010/05/podcast_show_notes_evolving_en.html Next, I have been working on the public sample code for the Oracle Service Bus 11g release. I'm now expanding my samples to include SCA, BPEL and the Oracle Adapters. This is really great experience for me because I have been learning these other tools to a deeper level and this provides insight into developing better solutions. You know the old saying, "If the only tool you have is a hammer, you tend to appraoch every problem as if it were a nail." However, I'm not the only one working on these samples. We have alot of our best and brightest working on sample code for the 11g release. Take a look at https://soasamples.samplecode.oracle.com/ to see all of the samples for SOA Suite 11g A reader wrote to me and asked me about using OSB to return information in JSON format. I don't have a sample posted for this yet, but I am working on getting one packaged up. In the mean time I can tell you that it is dead simple to do in OSB. Use the instructions I gave in an earlier blog entry on creating REST services using OSB, specify Messaging Service as the service type that takes a Text message and returns a Text message. Then have the OSB proxy service return a JSON formatted string (by replacing the contents of the $body variable with the JSON text) and you're done! This approach allows you to use OSB services from within Javascript/AJAX seamlessly. As I get more samples posted to the OTN site, I'll let you know. I have lots of interesting stuff on the way.

• Learning Objective-C for iPad/iPhone/iPod Development

  - by Jeff Julian

  I am learning how to write apps for the iPad/iPhone/iPod!  Why, well several reasons.  One reason, I have 5 devices in my house on the platform.  I had an iPad and iPhone, Michelle has an iPhone, and each of the kids have iPod Touches.  They are excellent devices for life management, entertainment, and learning.  I am amazed at how well the kids pick up on it and how much it effects the way they learn.  My two year old knows how to use it better than any other device we own and she is learning new words and letters so quickly. Because of this saturation at home, it would be fun to write some apps my family could use.  Some games to bring the hobby of development back into my life.  Second reason is we want to have a Geekswithblogs app for the iPhone and iPad.  We are not sure if it is purely informational (blog posts and tweets) or if members want to be able to publish from the app.  Creating a blog editor would be tough stuff, but could be just the right challenge. There are so many more reasons, but the last one that really makes me excited is that it is a new domain of development where I get excited when I think about writing apps.  That excitement level where I want to see if there are User Groups and if we are just watching TV, to break out the MBP and start working on it.  That excitement level where I could really read a development book cover to cover and not just use as a reference.  I really do like this feeling. Who knows how long this will last and I am definitely not leaving .NET.  Microsoft software will always be my main focus, but for the time, my hobby is changing and I am getting excited about development again.   Technorati Tags: Apple,iPad Development,Objective-C,New Frontiers Image: Courtesy of Apple

• How can one unlock a fully encrypted Ubuntu 11.10 system over SSH at boot?

  - by Jeff

  In previous versions of Ubuntu, and current versions of Debian, you can unlock a fully encrypted system (using dmcrypt and LUKS) at boot time over SSH. It was as easy as: Installing the encrypted system using the Ubuntu alternate installer disk or normal Debian installer disk and choosing to encrypt the system. After the system is installed, adding the dropbear and busybox packages. Updating the initram-fs to authorize your ssh key. At boot time, you'd just ssh to the machine, and do: echo -ne "keyphrase" > /lib/cryptsetup/passfifo The machine would then unlock and boot the encrypted system. Using the exact same steps on Ubuntu 11.10, I can ssh to the machine, but /lib/cryptsetup/passfifo doesn't exist. There appears to be no way to unlock the system over ssh. I'm not sure where to look to see if this functionality changed or if it was removed.

• AJAX event, prevents other page actions

  - by cobaltduck

  Here's a fairly average scenario, using JSF as an example, but this same concept I have observed in ASP.NET, Apache Wicket, and other frameworks with ajax capabilities. <h:inputText id="text1" value="#{myBacker.myBean.myStringVar}" styleClass="goodCSS"> <f:ajax event="change" listener="#{myBacker.text1ChangeEventMethod}" update="someOtherField" /> </h:inputText> <h:selectBooleanCheckbox id="check1" value="#{myBacker.myBean.myBoolVar}" /> Let's suppose that the 'text1ChangeEventListener' is essential to 'someOtherField' and perhaps toggles its disabled attribute, or changes its available options, based on the value of 'myStringVar.' The particulars aren't important, let's just accept that for some reason we need an ajax call when the 'text1' value is changed. So Jane User is working her way down the form. She arrives at the 'text1' field and types some value. The cursor focus is still in the text field, as she moves her mouse to the 'check1' box and clicks. It appears to her that nothing has happened. She clicks again, and this time the checkbox highlights and the icon indicating a selection appears in the box. Jane has to do several entries in the form today, and sees this happen every time, and it becomes very frustrating for her. Likewise, Jeff Admin is also perusing this form, and begins to type in 'text1.' He then realizes he doesn't really want to enter this data, and so moves his mouse to the "cancel" button elsewhere on the page, and clicks. Nothing seems to happen. Jeff clicks again, and after confirming he really does want to cancel, is returned to the home page. Jeff scratches his head. The problem is simply that the first thing the system does after 'text1' looses focus is run the listener and perform the ajax operation. It may only take a fraction of a second, but still, you can click other buttons all you want, but until that ajax has finished, everything else is ignored. I've spent the morning searching and reading, and it seems no one else has even noticed this. I could find not one article, blog, past question here or at SO, or anyting that addresses this obvious and glaring deficiency in ajax. So first of all, am I truly alone in thinking this is a big problem? Second, does anyone have a solution?

• Trade offs of linking versus skinning geometry

  - by Jeff

  What are the trade offs between inherent in linking geometry to a node versus using skinned geometry? Specifically: What capabilities do you gain / lose from using each method? What are the performance impacts of doing one over the other? What are the specific situations where you would want to do one over the other? In addition, do the answers to these questions tend to be engine specific? If so, how much?

• SPARC T5-4 LDoms for RAC and WebLogic Clusters

  - by Jeff Taylor-Oracle

  I wanted to use two Oracle SPARC T5-4 servers to simultaneously host both Oracle RAC and a WebLogic Server Cluster. I chose to use Oracle VM Server for SPARC to create a cluster like this: There are plenty of trade offs and decisions that need to be made, for example: Rather than configuring the system by hand, you might want to use an Oracle SuperCluster T5-8 My configuration is similar to jsavit's: Availability Best Practices - Example configuring a T5-8 but I chose to ignore some of the advice. Maybe I should have included an  alternate service domain, but I decided that I already had enough redundancy Both Oracle SPARC T5-4 servers were to be configured like this: Cntl 0.25  4  64GB

• How best do you represent a bi-directional sync in a REST api?

  - by Edward M Smith

  Assuming a system where there's a Web Application with a resource, and a reference to a remote application with another similar resource, how do you represent a bi-directional sync action which synchronizes the 'local' resource with the 'remote' resource? Example: I have an API that represents a todo list. GET/POST/PUT/DELETE /todos/, etc. That API can reference remote TODO services. GET/POST/PUT/DELETE /todo_services/, etc. I can manipulate todos from the remote service through my API as a proxy via GET/POST/PUT/DELETE /todo_services/abc123/, etc. I want the ability to do a bi-directional sync between a local set of todos and the remote set of TODOS. In a rpc sort of way, one could do POST /todo_services/abc123/sync/ But, in the "verbs are bad" idea, is there a better way to represent this action?

• The standards that fail us and the intellectual bubble

  - by Jeff

  There has been a great deal of noise in the techie community about standards, and a sudden and unexplainable hate for Flash. This noise isn't coming from consumers... the countless soccer moms, teens and your weird uncle Bob, it's coming from the people who build (or at least claim to build) the stuff those consumers consume. If you could survey the position of consumers on the topic, they'd likely tell you that they just want stuff on the Web to work.The noise goes something like this: Web standards are the correct and right thing to use across the Intertubes, and anything not a part of those standards (Flash) is bad. Furthermore, the more recent noise is centered around the idea that HTML 5, along with Javascript, is the right thing to use. The arguments against Flash are, well, the truth is I haven't seen a good argument. I see anecdotal nonsense about high CPU usage and things I'd never think to check when I'm watching Piano Cat on YouTube, but these aren't arguments to me. Sure, I've seen it crash a browser a few times, but it's totally rare.But let's go back to standards. Yes, standards have played an important role in establishing the ubiquity of the Web. The protocols themselves, TCP/IP and HTTP, have been critical. HTML, which has served us well for a very long time, established an incredible foundation. Javascript did an OK job, and thanks to clever programmers writing great frameworks like JQuery, is becoming more and more useful. CSS is awful (there, I said it, I feel SO much better), and I'll never understand why it's so disconnected and different from anything else. It doesn't help that it's so widely misinterpreted by different browsers. Still, there's no question that standards are a good thing, and they've been good for the Web, consumers and publishers alike.HTML 4 has been with us for more than a decade. In Web years, that might as well be 80. HTML 5, contrary to popular belief, is not a standard, and likely won't be for many years to come. In fact, the Web hasn't really evolved at all in terms of its standards. The tools that generate the standard markup and script have, but at the end of the day, we're still living with standards that are more than ten years old. The "official" standards process has failed us.The Web evolved anyway, and did not wait for standards bodies to decide what to do next. It evolved in part because Macromedia, then Adobe, kept evolving Flash. In the earlier days, it mostly just did obnoxious splash pages, but then it started doing animation, and then rich apps as they added form input. Eventually it found its killer app: video. Now more than 95% of browsers have Flash installed. Consumers are better for it.But I'll do it one better... I'll go out on a limb and say that Flash is a standard. If it's that pervasive, I don't care what you tell me, it's a standard. Just because a company owns it doesn't mean that it's evil or not a standard. And hey, it pains me to say that as a developer, because I think the dev tools are the suck (more on that in a minute). But again, consumers don't care. They don't even pay for Flash. The bottom line is that if I put something Flash based on the Internet, it's likely that my audience will see it.And what about the speed of standards owned by a company? Look no further than Silverlight. Silverlight 2 (which I consider the "real" start to the story) came out about a year and a half ago. Now version 4 is out, and it has come a very long way in its capabilities. If you believe Riastats.com, more than half of browsers have it now. It didn't have to wait for standards bodies and nerds drafting documents, it's out today. At this rate, Silverlight will be on version 6 or 7 by the time HTML 5 is a ratified standard.Back to the noise, one of the things that has continually disappointed me about this profession is the number of people who get stuck in an intellectual bubble, color it with dogmatic principles, and completely ignore the actual marketplace where this stuff all has to live. We aren't machines; Binary thinking that forces us to choose between "open standards" and "proprietary lock-in" (the most loaded b.s. FUD term evar) isn't smart at all. The truth is that the <object> tag has allowed us to build incredible stuff on top of the old standards, and consumers have benefitted greatly. Consumer desire, capitalism, and yes, standards ratified by nerds who think about this stuff for years have all played a role in the broad adoption of the Interwebs.We could all do without the noise. At the end of the day, I'm going to build stuff for the Web that's good for my users, and I'm not going to base my decisions on a techie bubble religion. Imagine what the brilliant minds behind the noise could do for the Web if they joined me in that pursuit.

• Accessing home directory hangs

  Occasionally my laptop will hang when trying to access my home directory.

• Use virtual pageviews for all goal tracking

  - by Jeff Wu

  Hi Pro Webmasters, I'm new to Google Analytics and I'm wondering if it would be cleaner to user virtual pageviews for all the goal tracking on my website instead of using a mix of regular page views and virtual pageviews. I know in most cases this is just semantics but there are multiple pages where the same goal can be achieved and I think it would be cleaner just to fire the same virtual pageview instead of having two different goal pages. Will this model also give developers more flexibility when they do development? I know we are moving to a CMS and urls can get hairy, so I think this might be a good way to make analytics portion of the site "future proof". Any thoughts are appreciated! Thanks.

• Testing loses its effectiveness if all programmers don't use them

  - by Jeff O

  Let's assume you are convinced that the extra time spent unit testing has merit and improves production. Does that still hold up when everyone working on the same code doesn't use them? This question makes me wonder if fixing tests that everyone doesn't use is a waste of time. If you correct a test so the new code will pass, you're assuming the new code is correct. The person updating the test better have a firm understanding of the reasoning behind the code change and decide if the test or the new code needs to be fixed. This much inconsistency in a team when it comes to testing is probably an indication of other problems as well. There is a certain amount of risk involved that someone else on the team will alter code that is covered by testing. Is this the point where testing becomes counter-productive?

• Advice for Storing and Displaying Dates and Times Across Different Time Zones

  A common question I receive from clients, colleagues, and 4Guys readers is for recommendations on how best to store and display dates and times in a data-driven web application. One of the challenges in storing and displaying dates in a web application is that it is quite likely that the visitors arriving at your site are not in the same time zone as your web server; moreover, it's very likely that your site attracts visitors from many different time zones from around the world. Consider an online messageboard site, like ASPMessageboard.com, where each of 1,000,000+ posts includes the date and time it was made. Imagine a user from New York leaves a post on April 7th at 4:30 PM and that the web server hosting the site is located in Dallas, Texas, which is one hour earlier than New York. When storing that post to the database do you record the post's date and time relative to the visitor (4:30 PM), the relative to the web server (3:30 PM), or some other value? And when displaying this post how do you show that date and time to a reader in San Francisco, which is three hours earlier than New York? Do you show the time relative to the person who made the post (4:30 PM), relative to the web server (3:30 PM), or relative to the user (1:30 PM)? And if you decide to store or display the date based on the poster's or visitor's time zone then how do you know their time zone and its offset? How do you account for daylight savings, and so on? This article provides guidance on how to store and display dates and times for visitors across different time zones and includes a demo that gives a working example of some of these techniques. Read on to learn more! Read More >
