• How can you use Windows Backup with a TrueCrypt encrypted backup destination?

  - by Burly

  Background There are numerous backup solutions out there for Windows and they come in many different forms. From a file copy and/or syncing tool like SyncBackSE to whole hard drive backup utilities based on Volume Shadow Copy like Acronis TrueImage or Norton Ghost to block level copy tools like dd. Each of these solutions offers different pros and cons versus the "Windows Backup and Restore Center" feature built-in to Windows Vista and Windows 7. I am not interested in discussing alternative backup solutions here however, as that has already been covered by numerous other questions. Contraints There are two "types" of backup supported by the "Windows Backup and Restore Center"(WBRC): - File backup (which Windows calls "Back Up Files") - Full System Backup (which Windows calls "Complete PC Backup) I am interested in a solution which supports either and/or both types of backup with WBRC. Questions How can you use a TrueCrypt encrypted mount point as the destination for the built-in "Windows Backup and Restore Center" feature in Windows Vista and 7? See-Also Volume Shadow Copy based backup that works with TrueCrypt References Backup and Restore Center Windows Vista - Backup and Restore Center Windows 7 - Backup and Restore Center

• Why do XSLT editors insert tab or space characters into XSLT to format it?

  - by pgfearo

  All XSLT editors I've tried till now add tab or space characters to the XSLT to indent it for formatting. This is done even in places within the XSLT where these characters are significant to the XSLT processor. XSLT modified for formatting in this way can produce output very different to that of the original XSLT if it had no formatting. To prevent this, xsl:text elements or other XSLT must be added to a sequence constructor to help separate formatting from content, this additional XSLT impacts on maintainability. Formatting characters also adversely impact on general usability of the tool in a number of ways (this is why word-processors don't use them I guess) and add to the size of the file. As part of a larger project I've had to develop a light-weight XSLT editor, it's designed to format XSLT properly, but without tab or space characters, just a dynamic left-margin for each new line. The XSLT therefore doesn't need additional elements to separate formatting tab or space characters from content. The problem with this is that if XSLT from this editor is opened in other XSLT editors, characters will be added for formatting reasons and the XSLT may therefore no longer behave as intended. Why then do existing XSLT editors use tabs or spaces for formatting in the first place? I feel there must be valid reasons, perhaps historical, perhaps practical. An answer will help me understand whether I need to put compatibility options in place in my XSLT editor somehow, whether I should simply revert to using tabs or spaces for both XSLT content and formatting (though this seems like a backwards step to me), or even whether enough XSLT users might be able to persuade their tools vendors to include alternative formatting methods to tabs or spaces. Note: I provided an XSLT sample demonstrating formatting differences in this answer to the question: Tabs versus spaces—what is the proper indentation character for everything, in every situation, ever?

• How can I find the Windows domain logon name of a user from within Outlook 2010?

  - by Chris Farmer

  I need to figure out someone's login name for our domain, and I'd like to be able to do this from within Outlook 2010. I used to be able to do this from Outlook 2007 by right-clicking the user's name in an email message that they'd sent me, and clicking "Outlook Properties..." in the context menu. That would bring up this dialog, which contained what I need in the "alias" field: Now I've installed Outlook 2010. I want to do the same thing, but I can't seem to find a corresponding field. First, I don't see an explicit "Outlook Properties" menu option anymore, and what I think is the corresponding dialog looks completely different: It seems weird that, although I'm looking at the properties of my own name in the same email message in 2007 and 2010 in these screenshots, my name is shown differently in each -- Chris versus Christopher. That makes me think that Outlook isn't really looking in the same place to get this info in each case. So, can I get that "alias" field from within Outlook 2010?

• Distinction between Cloud Servers and VPS

  - by Frank V

  What is the distinction between a Cloud based host and a VPS? I talked to a Rackspace Cloud sales person for around 45 minutes and never came to a real conclusion on this. So, to elaborate on my question a bit -- what benefits might a "cloud" server provide me versus a VPS provider such as Linode and vice versa -- what benefits would a VPS provide over a cloud provider? From what I've been able to ascertain, when you host on a cloud (with Rackspace Cloud) you get a instance of Linux in which you install software and such (a LAMP, for instance). From what I can figure, if the instance is running, I am charged and the pricing on Rackspace (according to what I understood from the sales rep) comes out to about $20 a month.... I was thinking a cloud customer pays per processing hours -- so if your app just sits there, no charges are incurred. Does one not pay of the cloud instance is shut down, perhaps? A similar questions to what I'm asking but not exactly it: Understanding: cloud-server, cloud-hosting, cloud-computing, the cloud What is the difference between vps and cloud hosting

• What happens when the USB key or SD card I've installed VMware ESXi on fails?

  - by ewwhite

  An SD (SDHC) card installed in an HP ProLiant DL380p Gen8 server running VMware ESXi just failed. I encountered some rather ominous looking messages on the vCenter console and in the HP ProLiant ILO event log... Lost connectivity to the device ... backing the boot filesystem. As a result, host configuration changes will not be saved to persistent storage. Embedded Flash/SD-CARD: Error writing media 0, physical block 848880: Stack Exception. VMware advocates the use of USB and SD (SDHC) boot devices for ESXi. It was one of the main reasons the smaller footprint ESXi was developed (versus the older ESX). I've spent much time highlighting the differences between ESXi's installable and embedded modes to coworkers and clients. However, these failures do seem to happen. In this case, this is my third instance. Luckily, this is a vSphere cluster with SAN storage. What steps should be taken to remediate this failure?

• Why does Ubuntu's Nautilus display a folder called "Examples" while the console displays "examples.desktop"

  - by broiyan

  These folders occur at /home/username. How does this name discrepancy arise? (Uppercase E versus lowercase e.) It seems to be a shortcut to /usr/share/example-content. How can I delete /usr/share/example-content/Ubuntu_Free_Culture_Showcase without using the command line? One possible answer is to make a privileged Nautilus using something like these SUSE instructions (link below). Unfortunately "gnomesu nautilus" gives me a "gnomesu: no such file" message and "sudo nautilus" does not do anything when added to the properties of the Launcher. Update: "sudo nautilus" from the console let's me delete but there is a mess of error messages. http://forums.opensuse.org/english/get-technical-help-here/how-faq-forums/unreviewed-how-faq/426153-how-nautilus-super-user-mode-gnome.html

• eBay Leads Mobile Commerce

  - by David Dorf

  For the first time, more smartphones where shipped than PCs. This important milestone helps reinforce that retailers need a strong mobile commerce strategy. IDC reported that for the 4th quarter of 2010, manufacturers shipped 100.9 million devices versus 92.1 million PCs shipped. One early adopter for the retail industry is eBay, the popular online auction and shopping site. In July 2008 they released their first mobile app and have increased investments ever since. In 2002 they bought PayPal for use with its online channel, but its becoming a force in the mobile world as well. In June 2010 they acquired RedLaser, the popular barcode scanning mobile app. Both pieces of technology enhance the mobile experience, and are available to other retailers as well. More recently, in December 2010 they acquired Critical Path Software, the developer of their eBay, StubHub, and Shopping.com mobile applications. Taking their mobile development in-house was a clear signal that mobile commerce is important to their strategy. Pop on over the eBay Inc's mobile commerce stats page to see just how well they are doing. You can use the animated map to see where people are using the app on any given day, and you can compare sales of the different categories. eBay's hottest category is Cars & Trucks, garnering 16.5% of the total $2B (yes, billion) in mobile sales in 2010. To understand why that category is so large, let's look at the top 10 most expensive cars sold on eBay mobile in 2010: $240,001 Mercedes-Benz: SLR McLaren $209,888 Lamborghini: Gallardo $208,500 Ferrari: 430 $199,900 Lamborghini: Gallardo $189,000 Lamborghini: Murcielago $185,000 Ferrari: 430 $175,000 Porsche: 911 $170,000 Ferrari: 550 $160,000 Bentley: Continental, GT $159,900 Lamborghini: Gallardo eBay claims they sell 3-4 Ferraris on their mobile app each month. Yes, mobile commerce is not limited to small items. While I would wait to get home and fire up the PC, the current generation that has grown up with mobile phones has no issue satisfying their impulses. Dave Sikora of Digby told me he's seen people buy furniture sets, mattresses, and diamonds via their mobile phones. I guess mobile commerce is rapidly becoming the norm.

• Linux halts every few seconds

  - by Zeppomedio

  We're having an issue where one our Linux boxes (Ubuntu 10.04 LTS, running on EC2 with a quadruple-large size, 68GB of RAM and 8 virtual cores with 3.25GHz each) freezes up every few seconds. Typing in an ssh session will freeze, and running strace on one of the Postgresql processes that's running usually shows: 02:37:41.567990 semop(7831581, {{3, -1, 0}}, 1 for a few seconds before it proceeds (it always gets stuck at that semop). OProfile shows that most of the time is spent in the kernel (60%) versus 37% in Postgresql. The result of these halts (which began suddenly a day ago) is that load on the box has gone from 0.7 to 10+, and causes our entire stack to slow done. Any ideas on how to track down what's going on? iostat doesn't show the disks being particularly slow or overloaded, and top shows user cpu % spike from 8% to about 40% whenever these back-ups happen.

• How to make ClearType looks ok even with large fonts

  - by Sorin Sbarnea

  I discovered that on large/huge fonts ClearType does have a negative impact. Just take a look at http://patterns.dataincubator.org/book/ page (check title with huge fonts versus normal text). If you are on Windows 7 you can use Win+Plus/Minus to zoom in/out. I'm looking for a configuration that would make both small fonts and large fonts look well. The system is Windows 7 but I suppose you could replicate the problem on Vista and even XP if you activate ClearType. Current results: ClearType on and tunned - small fonts looking good and large one looking bad ClearType off - small fonts looking bad and large one looking ok (smoothed)

• Understanding Process Scheduling in Oracle Solaris

  - by rickramsey

  The process scheduler in the Oracle Solaris kernel allocates CPU resources to processes. By default, the scheduler tries to give every process relatively equal access to the available CPUs. However, you might want to specify that certain processes be given more resources than others. That's where classes come in. A process class defines a scheduling policy for a set of processes. These three resources will help you understand and manage it process classes: Blog: Overview of Process Scheduling Classes in the Oracle Solaris Kernel by Brian Bream Timesharing, interactive, fair-share scheduler, fixed priority, system, and real time.

• Advantages of using pure JavaScript over JQuery

  - by Shivan Dragon

  What are the advantages of using Javascript-only versus using JQuery-only? I have limited experience with JavaScript and JQuery coding. I've added bits and snippets of each to HTML pages but I've mostly coded server-side stuff in other languages. I've noticed that while you can theoretically do the same things using either of the two approaches (and of course you can even mix 'em up in the same project) there seems to be a tendency to always start using JQuery from the very beginning no-matter what the project demands are. So I'm simply wondering, are there any punctual benefits to not use JQuery-only but instead to just use plain old JavaScript? I know this looks like a non-question because it can be said about it that "there's no definite answer" or "it can be debated for ever", but I'm actually hoping for punctual answers such as "You can do this in one approach and you cannot do it with the other". ==EDIT== As per scrwtp's comment, I'm not referring just to the DOM Handling part. My question is rather: JQuery is a library. For Javascript. What I find strange about this library as opposed to other libraries for other languages is that in JQyery's case it seems to be designed to be able to use it exclusively and not need to touch Javascript directly. This is as opposed to let's say Hibernate and SQL, where even though the library (or rather framework in this case, but I think the analogy still applies) takes the handle on A LOT of aspects, you still get to use SQL when using it, at least for some fringe cases. However in JQuery & Javascript case, you could do anything you do with Javascript using only JQuery (or at least that's how it seems to me).

• Ubuntu 10.04 LTS - good enough to jump on it?

  - by iconiK

  I'm currently planning to get a VPS from VPS.net for a PHP project. I personally haven't used CentOS (which is recommended all the time) and this is not a good time for me to start learning it, so I want to stick with Ubuntu, as that's the one I have experience with. Now there's the good ol' 8.04 LTS that's well supported, however, 10.04 LTS was released two days ago. I installed it on my laptop and it is pretty slick (doesn't matter for a server) and quick. But I am skeptical about it: Has anyone tried it in a production environment so far? How does it perform versus 8.04? Any serious bugs so far?

• Should I swap from WCF to NserviceBus

  - by Matt Roberts

  We have a central server that sends and recieves messages from a number of PCs that are located on client networks in various locations. To facilitate this, currently I'm using WCF with TCPNetBindings, using duplex communication secured with certificates. Now, we have a number of issues with this - mainly that we are being asked to support "disconnected mode" (we need to be fault tolerant). From what I know, there is no simple way to do this using the WCF stack - we'd need to implement something and perhaps use msmq. I've been looking at NServiceBus lately, and from I can see it seems to fit the bill well - fault tolerance, messages can be sent over the internet via a simple http gateway, etc. I know it's well respected in the community, and I can see why from looking into it. So, my question is...Does employing NServiceBus sound like a sensible idea, or does anyone have any other suggestions / real world experience that relate to this? I guess I'm worried of introducing a new tech that I know relatively little about, and facing problems with things like securing it, setting everything up in a reliable way, gotchas along the way.. I'm also wary of "gold-plating" the architecture, and choosing something shiny that will end up bogging me down in implementation versus sticking with WCF and just making it work for me.. Thanks!

• What are the advantages and disadvantages to using your real name online?

  - by Jon Purdy

  As a programmer, do you see any professional or other advantage in using your real name in online discourse, versus an invented handle? I've always gone by a single username and had my real name displayed whenever possible, for a few reasons: My interests online are almost exclusively professional and aboveboard. It constructs a search-friendly public log of all of my work, everywhere. If someone wants to contact me, there are many ways to do it. My portfolio of work is all tied to me personally. Possible cons to full disclosure include: If you feel like becoming involved in something untoward, it could be harder. The psychopath who inherits your project can more easily find out where you live. You might be spammed by people who are not worth the precious time that could be better spent writing more of the brilliant software you're famous for. Your portfolio of work is all tied to you personally. It seems, anyway, that a vast majority of StackOverflow users go by invented handles rather than real names. Notable exceptions include the best-known users, who are typically well established in the industry. But how could we ever become legendary rockstar programmers if we didn't get our names out there? Discuss.

• Is it safe to use S3 over HTTP from EC2, as opposed to HTTPS

  - by Marc

  I found that there is a fair deal of overhead when uploading a lot of small files to S3. Some of this overhead comes from SSL itself. How safe is it to talk to S3 without SSL when running in EC2? From the awesome comments below, here are some clarifications: this is NOT a question about HTTPS versus HTTP or the sensitivity of my data. I'm trying to get a feeling for the networking and protocol particularities of EC2 and S3. For example Are we guaranteed to be passing through only the AWS network when communicating from EC2 to S3 Can other AWS users (apart from staff) sniff my communications between EC2 and S3 Is authentication on their api done on every call, and thus credentials are passed on every call? Or is there some kind of authenticated session. I am using the jets3t lib. Feedback from people with some AWS experience would be appreciated. Thanks Marc

• null pointers vs. Null Object Pattern

  - by GlenH7

  Attribution: This grew out of a related P.SE question My background is in C / C++, but I have worked a fair amount in Java and am currently coding C#. Because of my C background, checking passed and returned pointers is second-hand, but I acknowledge it biases my point of view. I recently saw mention of the Null Object Pattern where the idea is than an object is always returned. Normal case returns the expected, populated object and the error case returns empty object instead of a null pointer. The premise being that the calling function will always have some sort of object to access and therefore avoid null access memory violations. So what are the pros / cons of a null check versus using the Null Object Pattern? I can see cleaner calling code with the NOP, but I can also see where it would create hidden failures that don't otherwise get raised. I would rather have my application fail hard (aka an exception) while I'm developing it than have a silent mistake escape into the wild. Can't the Null Object Pattern have similar problems as not performing a null check? Many of the objects I have worked with hold objects or containers of their own. It seems like I would have to have a special case to guarantee all of the main object's containers had empty objects of their own. Seems like this could get ugly with multiple layers of nesting.

• Firefox 3.6/4: modify/ tweak spell-check dictionary?

  - by studiohack

  I edit frequently on Super User, and it is a pain to edit for capitalization or words that are shortened, i.e. Win7 instead of Windows 7, or windows versus Windows. Using Firefox 3.6 and/or 4, Is there a way (using an extension or configure settings) I can configure the dictionary to automatically recognize words that may not be capitalized or are shortened (while editing a post)? Say, have the dictionary see Win7 and underline it so that I can right-click on it, and select Windows 7? I would want it to be configurable, so I can tell it what to look for, etc... Ideas or recommendations?

• Thumbs Up or Thumbs Down – Intel Debuts Prototype Palm-Reading Tech to Replace Passwords [Poll]

  - by Asian Angel

  This week Intel debuted prototype palm-reading tech that could serve as a replacement for our current password system. Our question for you today is do you think this is the right direction to go for better security or do you feel this is a mistake? Photo courtesy of Jane Rahman. Needless to say password security breaches have been a hot topic as of late, so perhaps a whole new security model is in order. It would definitely eliminate the need to remember a large volume of passwords along with circumventing the problem of poor password creation/selection. At the same time the new technology would still be in the ‘early stages’ of development and may not work as well as people would like. Long-term refinement would definitely improve its performance, but would it really be worth pursuing versus the actual benefits? From the blog post: Intel researcher Sridhar Iyendar demonstrated the technology at Intel’s Developer Forum this week. Waving a hand in front of a “palm vein” detector on a computer, one of Iyendar’s assistants was logged into Windows 7, was able to view his bank account, and then once he moved away the computer locked Windows and went into sleeping mode.

• How do I choose a package format for Linux software distribution?

  - by Ian C.

  We have a Java-based application that, to date, we've been distributing as a tarball with instructions for deploying. It's mostly self-contained so deployment is fairly straight-forward: Untar on the disk you'd like it to live on; Make sure Java is in your path and a suitable distro and version; Verify ownership and group on all the files Start up the server processes with our start script If the user wants to get in to start-on-boot stuff with SysV we have some written instructions and a template init file for it in our tarball. We'd like to make this installation process a little more seamless; take care of the permissions and the init script deployment. We're also going to start bundling our own JRE with the application so that we're mostly free of external dependencies. The question we're faced with now is: how do we pick a package format for distribution? Is RPM the standard? Can all package management tools deal with it now? Our clients primarily run RHEL and CentOS, but we do have some using SuSE and even Debian. If we can pick a distro-agnostic format we'd prefer that. What about a self-extracting shell script? Something akin to how Java is distributed. If we're dependency-free would the self-extracting script be sufficient? What features or conveniences would we lose out on going with the script versus a proper package format meant for use by a package manager?

• Podcast Show Notes: Are You Future Proof?

  - by Bob Rhubart

  On September 14, 2012 ZDNet blogger Joe McKendrick published Why IT is a Profession in Flux, a short article in which he makes the observation that "IT professionals are under considerable pressure to deliver more value to the business, versus being good at coding and testing and deploying and integrating." I forwarded that article to my list of Usual Suspects (the nearly 40 people who have participated in the podcast over the last 3 years), along with a suggestion that I wanted to put together a panel discussion to further explore the issue. This podcast is the result. As it happened, three of the people who responded to my query were in San Francisco for Oracle OpenWorld, as was I, so I seized the rare opportunity for a face to face conversation. The participants are all Oracle ACE Directors, as well as architects: Ron Batra, Director of Cloud Computing at AT&T Basheer Khan, Founder, President and CEO at Innowave Technology Ronald van Luttikhuizen, Managing Partner at Vennster. The Conversation Listen to Part 1 Future-Proofing: As powerful forces reshape enterprise IT, your IT and software development skills may not be enough. Listen to Part 2 Survival Strategy: Re-tooling one’s skill set to reflect changes in enterprise IT, including the knowledge to steer stakeholders around the hype to what’s truly valuable. Listen to Part 3 Writing on the Wall: Do the technological trends that are shaping enterprise IT pose any threat to basic software development roles? What opportunities do these changes represent? The entire conversation is also available in video format from the OTN YouTube Channel. Your Two Cents What are you doing to future-proof your IT career? Share your thoughts in the comments section.
