• Picking a code review tool

  - by marcog

  We are a startup looking to migrate from Fogbugz/Kiln to a new issue tracker/code review system. We are very happy with Jira, especially the configurability, but we are undecided on a code review tool. We have been trialing Bitbucket, but it doesn't fit our workflow well. Here are the problems we have identified with BB: Comments can be hard to find: when commenting on code not visible in the diff when code that is commented on is later changed viewing the full file doesn't include comments (also doesn't show changes) Viewing comments on individual commits can be a pain We have the implementer merge the diff and close the issue, whereas pull requests are more suited to the open source model where someone with commit rights merges We would like to automate creation of the code review (either from Jira or a command line tool) No syntax highlighting Once the pull request exceeds a certain size, BB won't show the whole thing and you have to view individual commits Linking BB pull requests to Jira issues is a bit janky: we have a pull request URL field on Jira, but this doesn't work when there are changes in multiple repositories Does anyone have any good suggestion given the above? We are tight on budget, and Jira integration is a big plus. We also have multiple commits per issue, and would like to have the option of viewing individual commits in the review. It might also be worth noting that we have a separate reviewer and tester for each issue.

• Why are marketing employees, product managers, etc. deserving of their own office, yet programmers are jammed in a room as many as possible?

  - by TheImirOfGroofunkistan

  I don't understand why many (many) companies treat software developers like they are assembly line workers making widgets. Joel Spolsky has a great example of the problems this creates: With programmers, it's especially hard. Productivity depends on being able to juggle a lot of little details in short term memory all at once. Any kind of interruption can cause these details to come crashing down. When you resume work, you can't remember any of the details (like local variable names you were using, or where you were up to in implementing that search algorithm) and you have to keep looking these things up, which slows you down a lot until you get back up to speed. Here's the simple algebra. Let's say (as the evidence seems to suggest) that if we interrupt a programmer, even for a minute, we're really blowing away 15 minutes of productivity. For this example, lets put two programmers, Jeff and Mutt, in open cubicles next to each other in a standard Dilbert veal-fattening farm. Mutt can't remember the name of the Unicode version of the strcpy function. He could look it up, which takes 30 seconds, or he could ask Jeff, which takes 15 seconds. Since he's sitting right next to Jeff, he asks Jeff. Jeff gets distracted and loses 15 minutes of productivity (to save Mutt 15 seconds). Now let's move them into separate offices with walls and doors. Now when Mutt can't remember the name of that function, he could look it up, which still takes 30 seconds, or he could ask Jeff, which now takes 45 seconds and involves standing up (not an easy task given the average physical fitness of programmers!). So he looks it up. So now Mutt loses 30 seconds of productivity, but we save 15 minutes for Jeff. Ahhh! Quote Link More Spolsky on Offices Why don't managers and owner's see this?

• How do you research while pair programming?

  - by traffichazard

  I've recently started at a new job and pairing has helped me become effective there very quickly. I am, however, having a hard time when we must do brief joint research during our workflow, covering API features, code examples, or command options. My team lead urges us to do all research on our pairing station, rather than our individual laptops, and to synchronize our research by verbally negotiating the steps between different web resources. I research, read, and absorb information differently from my pairing partner, and I feel much more productive when I can follow a thread of research to the next web page exactly when I want to, rather than trying to keep exact pace and place with what my partner's reading. We're both smart and fast, but we can't help moving in different ways and instantaneous velocities when we're figuring stuff out. It seems so much easier to poke around individually for a minute until one of us says "I've got it," then get back together and code. When you pair program, how do you handle short research tasks? What works best for you, and how to you keep in sync with your partner?

• Windows Embedded CE DiskPrep PowerToy

  - by Bruce Eitman

  Kurt Kennett from Microsoft has offered up a handy new tool. This tool is useful for creating a boot disk for x86 Windows CE systems that use the BIOSLoader. This is especially useful for creating disks with formats other than FAT16, which are fairly easy to create. I am letting you know about this new tool, but I have to be honest in telling you that I haven’t used it myself because it is for Windows Vista and Windows 7 – which I don’t have available right now. But you can bet that I will be setting up a virtual machine to give it a try. Here is what Kurt has to say about the tool: Download the DiskPrep Tool  DiskPrep can prepare any hard disk that can be attached to your development PC so that it can boot your X86-based Windows CE OS Design. USB disks (including disk "keys"), Compact Flash Cards, and SD cards all work if your system bios can boot from that type of media. FAT16, FAT32, and exFAT all supported. DOS is not used - the program prepares the bios loader on the disk and only uses that. If you use Windows Vista or Windows 7, you can use VHD files for VirtualPC. This allows for rapid prototyping of a self-booting system. Copyright © 2010 – Bruce Eitman All Rights Reserved

• Re-running SSRS subscription jobs that have failed

  - by Rob Farley

  Sometimes, an SSRS subscription for some reason. It can be annoying, particularly as the appropriate response can be hard to see immediately. There may be a long list of jobs that failed one morning if a Mail Server is down, and trying to work out a way of running each one again can be painful. It’s almost an argument for using shared schedules a lot, but the problem with this is that there are bound to be other things on that shared schedule that you wouldn’t want to be re-run. Luckily, there’s a table in the ReportServer database called dbo.Subscriptions, which is where LastStatus of the Subscription is stored. Having found the subscriptions that you’re interested in, finding the SQL Agent Jobs that correspond to them can be frustrating. Luckily, the jobstep command contains the subscriptionid, so it’s possible to look them up based on that. And of course, once the jobs have been found, they can be executed easily enough. In this example, I produce a list of the commands to run the jobs. I can copy the results out and execute them. select 'exec sp_start_job @job_name = ''' + cast(j.name as varchar(40)) + '''' from msdb.dbo.sysjobs j  join  msdb.dbo.sysjobsteps js on js.job_id = j.job_id join  [ReportServer].[dbo].[Subscriptions] s  on js.command like '%' + cast(s.subscriptionid as varchar(40)) + '%' where s.LastStatus like 'Failure sending mail%'; Another option could be to return the job step commands directly (js.command in this query), but my preference is to run the job that contains the step.

• How to write PowerShell code part 1 (Using external xml configuration file)

  - by ybbest

  In this post, I will show you how to use external xml file with PowerShell. The advantage for doing so is that you can avoid other people to open up your PowerShell code to make the configuration changes; instead all they need to do is to change the xml file. I will refactor my site creation script as an example; you can download the script here and refactored code here. 1. As you can see below, I hard code all the variables in the script itself. $url = "http://ybbest" $WebsiteName = "Ybbest" $WebsiteDesc = "Ybbest test site" $Template = "STS#0" $PrimaryLogin = "contoso\administrator" $PrimaryDisplay = "administrator" $PrimaryEmail = "[email protected]" $MembersGroup = "$WebsiteName Members" $ViewersGroup = "$WebsiteName Viewers" 2. Next, I will show you how to manipulate xml file using PowerShell. You can use the get-content to grab the content of the file. [xml] $xmlconfigurations=get-content .\SiteCollection.xml 3. Then you can set it to variable (the variable has to be typed [xml] after that you can read the content of the xml content, PowerShell also give you nice IntelliSense by press the Tab key. [xml] $xmlconfigurations=get-content .\SiteCollection.xml $xmlconfigurations.SiteCollection $xmlconfigurations.SiteCollection.SiteName 4. After refactoring my code, I can set the variables using the xml file as below. #Set the parameters $siteInformation=$xmlinput.SiteCollection $url = $siteInformation.URL $siteName = $siteInformation.SiteName $siteDesc = $siteInformation.SiteDescription $Template = $siteInformation.SiteTemplate $PrimaryLogin = $siteInformation.PrimaryLogin $PrimaryDisplay = $siteInformation.PrimaryDisplayName $PrimaryEmail = $siteInformation.PrimaryLoginEmail $MembersGroup = "$WebsiteName Members" $ViewersGroup = "$WebsiteName Viewers"

• How do I install GRUB on a RAID system installation?

  - by root45

  I'm trying to setup and install Ubuntu on a RAID 1 setup. I have two disks, sdb and sdc. I've been following this guide https://help.ubuntu.com/community/Installation/SoftwareRAID which more or less works for getting everything set up and Ubuntu installed. The problem is at the end of the installation, it tries to install GRUB. By default it tries my "first disk", which gives a "fatal error". I've tried installing it on a specific partion, e.g. sdb1 as well as RAID devices, e.g. md0, md1, etc.. Nothing seems to work. Edit: The actual error is "Unable to install GRUB in /dev/sdb Executing 'grub-install '/dev/sdb' failed. This is a fatal error." Then I'm taken back to the main install menu. If I choose "Install the GRUB boot loader on a hard disk" option, I can pick the partition, but entering sdb2 or md1 gives the same error. So I went ahead an just didn't install GRUB, which means now I presumably have a working Ubuntu installation, but I can't boot it. I've tried booting from the LiveCD to install GRUB, but I can't chroot into my system because it doesn't seem to recognize that my disk is a Linux disk. There's an error about it being a RAID partition. So basically I would really like to know how you know to which device to install GRUB at installation, or at the very least, how to install it on to my system now. I suppose I should also mention that sda is a Windows 7 installation that I would like to keep around and be able to access at boot. Thanks for any help.

• Full-text indexing? You must read this

  - by Kyle Hatlestad

  For those of you who may have missed it, Peter Flies, Principal Technical Support Engineer for WebCenter Content, gave an excellent webcast on database searching and indexing in WebCenter Content.  It's available for replay along with a download of the slidedeck.  Look for the one titled 'WebCenter Content: Database Searching and Indexing'. One of the items he led with...and concluded with...was a recommendation on optimizing your search collection if you are using full-text searching with the Oracle database.  This can greatly improve your search performance.  And this would apply to both Oracle Text Search and DATABASE.FULLTEXT search methods.  Peter describes how a collection can become fragmented over time as content is added, updated, and deleted.  Just like you should defragment your hard drive from time to time to get your files placed on the disk in the most optimal way, you should do the same for the search collection. And optimizing the collection is just a simple procedure call that can be scheduled to be run automatically.   [Read more]

And just as a reminder, be sure to involve your DBA with your WebCenter Content implementation as you go to production and over time.  We recently had a customer complain of slow performance of the application when it was discovered the database was starving for memory.  So it's always helpful to keep a watchful eye on your database.

• Upgrading from 2005 to R2

  - by DavidWimbush

  We're about to take the plunge and upgrade our servers from SQL 2005 to SQL 2008 R2. Real world accounts of people upgrading to R2 are a bit hard to find so I thought it might be useful to blog what happens. (I don't count marketing 'case studies' that just say stuff like "The process was effortless and the upgrade will pay for itself by the end the week.") We're using the database engine, Analysis Services and Reporting Services so upgrading by a major version number was looking a bit daunting. I wasn't expecting much trouble on the engine side of things but, as most of the action in 2008 and R2 appears to have been on the Reporting and BI front, I expected to have quite a bit of work to do. But our testing so far has been one nice surprise after another: The 2005 backups restore cleanly onto R2. R2's BI Studio upgraded the Reporting and Analysis Services solutions without any issues. The cubes all deployed and processed just fine. R2 BI Studio interacts fine with TFS 2008 version control. I'll blog some more as things develop.

• .NET Reflector & .NET Reflector Pro 6.1 have been released

  - by Bart Read

  .NET Reflector 6.1 and .NET Reflector Pro 6.1 have been released. You can download them from: http://www.red-gate.com/products/reflector/index.htm .NET Reflector is a class browser and disassembler for .NET assemblies. .NET Reflector Pro is a Visual Studio debugging extension that allows you to step through third party and framework assemblies, as if they were built from your own source code. This release fixes several problems that were present in the 6.0 release: Support for using a copy of Reflector.cfg stored alongside Reflector.exe has been re-enabled so users upgrading from 5.x releases will not lose their settings. Fixed unhandled exception on exit of Visual Studio when .NET Reflector add-in used in conjunction with TestDriven.NET add-in. Added better support for dealing with framework assemblies, which only contain meta-data, in the "Referenced Assemblies" folder. Fixed problem where attempted decompilation with CppCliLanguage add-in would lead to display of a page on the Red Gate website. Added option to activate .NET Reflector Pro to .NET Reflector menu in Visual Studio after receiving feedback from a number of users that it was hard to figure out how to activate the product. For more details about the products please visit: http://www.red-gate.com/products/reflector/index.htm

• 2D character controller in unity (trying to get old-school platformers back)

  - by Notbad

  This days I'm trying to create a 2D character controller with unity (using phisics). I'm fairly new to physic engines and it is really hard to get the control feel I'm looking for. I would be really happy if anyone could suggest solution for a problem I'm finding: This is my FixedUpdate right now: public void FixedUpdate() { Vector3 v=new Vector3(0,-10000*Time.fixedDeltaTime,0); _body.AddForce(v); v.y=0; if(state(MovementState.Left)) { v.x=-_walkSpeed*Time.fixedDeltaTime+v.x; if(Mathf.Abs(v.x)>_maxWalkSpeed) v.x=-_maxWalkSpeed; } else if(state(MovementState.Right)) { v.x= _walkSpeed*Time.fixedDeltaTime+v.x; if(Mathf.Abs(v.x)>_maxWalkSpeed) v.x=_maxWalkSpeed; } _body.velocity=v; Debug.Log("Velocity: "+_body.velocity); } I'm trying here to just move the rigid body applying a gravity and a linear force for left and right. I have setup a physic material that makes no bouncing and 0 friction when moving and 1 friction with stand still. The main problem is that I have colliders with slopes and the velocity changes from going up (slower) , going down the slope (faster) and walk on a straight collider (normal). How could this be fixed? As you see I'm applying allways same velocity for x axis. For the player I have it setup with a sphere at feet position that is the rigidbody I'm applying forces to. Any other tip that could make my life easier with this are welcomed :). P.D. While coming home I have noticed I could solve this applying a constant force parallel to the surface the player is walking, but don't know if it is best method.

• Advice for a computer science sophomore in college?

  - by RDas

  Hi Everyone! I'm a sophomore in college majoring in Computer Science and Math. I have always loved programming. I started programming in C when I was nine years old and over the years I've picked up Visual Basic, C#, Java, C++, JavaScript, Objective-C, Python, Ruby, elementary Haskell and elementary Erlang, and I learned Perl back in the day which I've mostly forgotten. I have not done much network programming. I have done CGI programming, but that was about six/seven years ago. I've done some socket programming and written (school) programs to do interprocess communication, which I understood and liked. I'm taking a course on client/server programming and another one on network security next semester, which I am really looking forward to. I'm seeking advice on how to proceed with future learning. I've mostly done application (mobile and desktop) development, not much of web development. I'd like to pick up some web development this coming semester. Since I know Ruby and Python, should I start by learning Django and/or Rails? Any other suggestions on starting web development? I have a good understanding of HTML and CSS. Also, I'd also like to know how hard it is to pick up and be good (read: productive) in functional programming languages coming from a purely structured/object oriented background? I've been reading up on Erlang and Haskell, and I'd like to know your opinions on whether it's worth my time trying to learn them. What about Lisp, Scheme and other functional languages? Any help/ideas would be really appreciated.

• How to penetrate the QA industry after layoffs, next steps...

  - by Erik

  Briefly, my background is in manual black box testing of websites and applications within the Agile/waterfall context. Over the past four years I was a member of two web development firms' small QA teams dedicated to testing the deployment of websites for national/international non profits, governmental organizations, and for profit business, to name a few: -Brookings Institution -Senate -Tyco Electronics -Blue Cross/Blue Shield -National Geographic -Discover Channel I have a very strong understanding of the: -SDLC -STLC of bugs and website deployment/development -Use Case & Test Case development In March of this year, my last firm downsized and lost my job as a QA tester. I have been networking and doing a very detailed job search, but have had a very difficult time getting my next job within the QA industry, even with my background as a manual black box QA tester in the website development context. My direct question to all of you: What are some ways I can be more competitive and get hired? Options that could get me competitive: Should I go back to school and learn some more 'hard' skills in website development and client side technologies, e.g.: -HTML -CSS -JavaScript Learn programming: -PHP -C# -Ruby -SQL -Python -Perl -?? Get Certified as a QA Tester, there are a countless numbers of programs to become a Certified Tester. Most, if not all jobs, being advertised now require Automated Testing experience, in: -QTP -Loadrunner -Selenium -ETC. Should I learn, Automated testing skills, via a paid course, or teach myself? --Learn scripting languages to understand the automated testing process better? Become a Certified "Project Management Professional" (PMP) to prove to hiring managers that I 'get' the project development life cycle? At the end of the day I need to be competitive and get hired as a QA tester and want to build upon my skills within the QA web development field. How should I do this, without reinventing the wheel? Any help in this regard would be fabulous. Thanks! .erik

• Help with a simple incremental backup script

  - by Evan

  I'd like to run the following incomplete script weekly in as a cron job to backup my home directory to an external drive mounted as /mnt/backups #!/bin/bash # TIMEDATE=$(date +%b-%d-%Y-%k:%M) LASTBACKUP=pathToDirWithLastBackup rsync -avr --numeric-ids --link-dest=$LASTBACKUP /home/myfiles /mnt/backups/myfiles$TIMEDATE My first question is how do I correctly set LASTBACKUP to the the the directory in /backs most recently created? Secondly, I'm under the impression that using --link-desk will mean that files in previous backups will not will not copied in later backups if they still exist but will rather symbolically link back to the originally copied files? However, I don't want to retain old files forever. What would be the best way to remove all the backups before a certain date without losing files that may think linked in those backups by currents backups? Basically I'm looking to merge all the files before a certain date to a certain date if that makes more sense than the way I initially framed the question :). Can --link-dest create hard links, and if so, just deleting previous directories wouldn't actually remove linked file? Finally I'd like to add a line to my script that compresses each newly created backup folder (/mnt/backups/myfiles$TIMEDATE). Based on reading this question, I was wondering if I could just use this line gzip --rsyncable /backups/myfiles$TIMEDATE after I run rsync so that sequential rsync --link-dest executions would find already copied and compressed files? I know that's a lot, so many thanks in advance for your help!!

• Announcing Sesame Data Browser

  - by Fabrice Marguerie

  At the occasion of MIX10, which is currently taking place in Las Vegas, I'd like to announce Sesame Data Browser.Sesame will be a suite of tools for dealing with data, and Sesame Data Browser will be the first tool from that suite.Today, during the second MIX10 keynote, Microsoft demonstrated how they are pushing hard to get OData adopted. If you don't know about OData, you can visit the just revamped dedicated website: http://odata.org. There you'll find about the OData protocol, which allows you to publish and consume data on the web, the OData SDK (with client libraries for .NET, Java, Javascript, PHP, iPhone, and more), a list of OData producers, and a list of OData consumers.This is where Sesame Data Browser comes into play. It's one of the tools you can use today to consume OData.I'll let you have a look, but be aware that this is just a preview and many additional features are coming soon.Sesame Data Browser is part of a bigger picture than just OData that will take shape over the coming months. Sesame is a project I've been working on for many months now, so what you see now is just a start :-)I hope you'll enjoy what you see. Let me know what you think.

• What's the value of a Facebook fan?

  In his blog posting titled "Why Each Facebook Fan Is Worth $2,000 to J. Crew," Joe Skorupa lays out a simplistic calculation for assigning a value to social media efforts within Facebook. While I don't believe the metric, at least its a metric that can be applied consistently. Trying to explain the ROI to management to start a program, then benchmarking to show progress isn't straightforward at all. Social media isn't really mature enough to have hard-and-fast rules around valuation (yet). When I'm asked by retailers how to measure social media efforts, I usually fess-up and say I can't show an ROI but the investment is so low you might was well take a risk. Intuitively, it just seems like a good way to interact with consumers, and since your competition is doing it, you better do it as well. Vitrue, a social media management company, has calculated a fan as being worth $3.60 per year based on impressions generated in Facebook's news feed. That means a fan base of 1 million translates into at least $3.6 million in equivalent media over a year. Don't believe that number either? Fine, Vitrue now has a tool that let's you adjust the earned media value of a fan. Jump over to http://evaluator.vitrue.com/ and enter your brand's Facebook URL to get an assessment of the current value and potential value. For fun, I compared Abercrombie & Fitch (1,077,480 fans), Gap (567,772 fans), and Wet Seal (294,479 fans). The image below shows the results assuming the default $5 earned media value for a fan. The calculation is more complicated than just counting fans. It also accounts for postings and comments. Its possible for a brand with fewer fans to have a higher value based on frequency and relevancy of posts. The tool gathers data via the Social Graph API for the past 30 days of activity. I'm not sure this tool assigns the correct value either, but hey, its a great start.

• Implement Budget Allocation in DAX for Power Pivot and Tabular #powerpivot #tabular #ssas #dax

  - by Marco Russo (SQLBI)

  Comparing sales and budget, or costs and budget, is a very common operation. However, it is often the case that you have different granularities for different tables containing budget and the data to compare with. There are two ways to do that: you can limit the comparison to the granularity that is common to the two tables, or you can allocate the budget where it’s not defined. For example, if you have a budget defined by quarter and category, you might want to allocate it by month and product. In this way, you will do the comparison as you had a more granular definition of the budget, without actually having to do the manual job of allocating data (usually in an Excel worksheet!). If you want to do budget allocation in DAX, you can use the Budget Patterns we published on DAX Patterns. If you come from and MDX/OLAP background, at first you might find it hard to solve the problem of not having attribute hierarchies that helps you in propagating the budget values to lower hierarchical levels. However, I think that once you get used to DAX, you will find the behavior very predictable and easy to “debug” also for more complex allocation formula. You just have to be careful in writing the DAX formula, but probably the pattern we wrote should help you designing the right data model, without creating physical relationships to the budget table! This pattern is also based on the Handling Different Granularities scenario I discussed a couple of weeks ago.

• Can&rsquo;t eject external USB or Firewire drive in Windows 7

  - by Kelly Jones

  As a SharePoint developer, I work a lot with Virtual Machines (presently using Windows Virtual PC, with Windows 7).  I’m using these VMs with my laptop, and in order to get better performance, I’ve moved them to external hard drives.  (These drives have faster RPMs, larger caches, and a larger capacity, than the internal drive.)  I have one large external drive at home, another similar drive at the office, and a small, slow portable drive that I carry with me. So, at the end of each day at the office, I copy the files from the external drive to my portable drive and then once I get home, I copy them from the portable to the larger external drive I leave at home.  I do this for a couple of reasons: so I can work at home and secondly, so I have backup copies.  (Often, I feel like I’m in the movie “Office Space” when copying the files before I leave the office). Anyway, after the files are copied, I safely eject the external drives, and then hibernate my laptop.  I’ve been doing this for over a year now, but within the last couple of months I started to have issues disconnecting the drives.  Intermittently, some application/process would have a lock on some file on the drive that would keep Windows from safely ejecting it. After looking into it, I found that it was actually the Windows search service that was accessing the drive! Since I wasn’t using Windows search to look for stuff on these drives, I removed them as locations to index. To do this in Windows 7, you need to go to Indexing Options (just type “Indexing” into the search box in the Start menu…).  One of the choices displayed will then be Indexing Options, so click on it and you should then see a window similar to this:   Click on the Modify button and you’ll see this window: Notice the different drives listed above.  My “FreeAgent XTreme (F:)” drive was checked for some reason, which was causing the indexing service to scan the drive looking for new files to make available in the search results.  Ever since I unchecked this box, I’ve been able to safely eject the drive.

• Fixing unbootable installation on LVM root from Desktop LiveCD

  - by intuited

  I just did an installation from the 10.10 Desktop LiveCD, making the root volume an LVM LV. Apparently this is not supported; I managed it by taking these steps before starting the GUI installer app: installing the lvm2 package on the running system creating an LVM-type partition on the system hard drive creating a physical volume, a volume group and a root LV using the LVM tools. I also created a second LV for /var; this I don't think is relevant. creating a filesystem (ext4) on each of the two LVs. After taking these steps, the GUI installer offered the two LVs as installation targets; I gladly accepted, also putting /boot on a primary partition separate from the LVM partition. Installation seemed to go smoothly, and I've verified that both the root and var volumes do contain acceptable-looking directory structures. However, booting fails; if I understood correctly what happened, I was dropped into a busybox running in the initrd filesystem. Although I haven't worked through the entirety of the grub2 docs yet, it looks like the entry that tries to boot my new system is correct: menuentry 'Ubuntu, with Linux 2.6.35-22-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod part_msdos insmod ext2 set root='(hd0,msdos3)' search --no-floppy --fs-uuid --set $UUID_OF_BOOT_FILESYSTEM linux /vmlinuz-2.6.35-22-generic root=/dev/mapper/$LVM_VOLUME_GROUP-root ro quiet splash initrd /initrd.img-2.6.35-22-generic } Note that $VARS are replaced in the actual grub.cfg with their corresponding values. I rebooted back into the livecd and have unpacked the initrd image into a temp directory. It looks like the initrd image lacks LVM functionality. For example, if I'm reading /usr/share/initramfs-tools/hooks/lvm2 (installed with lvm2 on the livecd-booted system, not present on the installed one) correctly, an lvm executable should be situated in /sbin; that is not the case. What's the best way to remedy this situation? I realize that it would be easier to just use the alternate install CD, which apparently supports LVM, but I don't want to wait for it to download and then have to reinstall.

• Windows 8, the biggest struggle&hellip;.

  - by Dennis Vroegop

  As always, it’s hard to be original. It’s easy to copy great stuff others have done but to think of something nice that others might have done is not trivial. The number of applications in the Windows 8 Store is growing rappidly. That was to be expected; a lot of developers already have the skills needed to build Win8 apps so all it took was some ideas. And they have ideas. Another factor that helps with the growing number of apps in the store is the availability of the project templates in Visual Studio 2012. When you start a new project you are given a ready to run sample that you can adapt to your needs. All the stuff needed to navigate through the app, to display data, to do semantic zoom, it’s all available. So what do we do? We tweak, change, adapt and modify these samples to fit our application. However, the underlying structure of the app remains the same. Somehow developers can’t seem to break free from the structure that the sample apps give you. Result: all apps looks alike. My tip for the day: take the samples and use them to learn. Don’t use them as a foundation of your app. Make you app different from those others and you’ll find you will have something special. I’m curious to see what you come up with!
