• Public Solaris/SPARC roadmap until 2015

  - by Karim Berrah

  It now public, and give you a nice overview on what's going on, where Oracle is going with Solaris and SPARC processors. It's now available from here. What can we lean from this roadmap ? well, if you look carefully: Oracle is announcing Solaris 11 this year. The release date should be ... check OOW11 Solaris 10 updates should still be released in 2012 (remember, released in 2005). Check the Solaris lifecycle to understand how long is Solaris to stay side by side with Solaris 11. in 2011, a great 3x Single Strand improvement for the T-Series. Some thing great under preparation. Probably revealed at Oracle Open World 2011. Good news for ISVs ! in 2012, a great 6x Troughput improvement for the M-Serie ! How can this be done ? .... Nearly everything on the SPARC/SOLARIS level is said through the public roadmap,but as you know the evil is in the details ;)

• Large file copy from NFS to local disk performance drop

  - by Bernhard

  I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler). I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit. At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes. Any ideas what could be causing this?

• Remote access not working without connected monitor

  - by winSharp93

  I am trying to configure a Windows Server 2008 as a Home Server for my personal use (mainly for storing documents, hosting source-control, etc.). The "server" consists of an Intel Atom 2700DC board and an Intel SSD. Configuring remote access to the server, I am confronted with a very strange problem: As long as a monitor is connected to my server, remote access works without any problems. However, when no monitor is connected at boot-time, remote access simply won't work (I keep getting errors when trying to connect that the remote server was not found or that remote access is disabled). Windows definitely boots when no monitor is connected as I receive a message asking me whether to enter safe mode when booting after powering the server down by plugging the power cord. When I plug in a monitor after boot, it stays turned off and remote desktop connections still fail. Do you have any ideas about what I could try?

• Book Review: Professional ASP.Net MVC4

  - by Sam Abraham

  The past few weeks have been particularly busy as I continue to dedicate a bigger portion of my free time to refreshing my memory and enhancing my knowledge of best practices pertaining to technologies we plan on using for a major upcoming project. In this blog post, I will be providing a brief overview of my latest reading “Professional ASP.Net MVC4” by Jon Galloway, Phil Haack, Brad Wilson and K. Scott Allen. This book is a must read for web developers looking to enhance their MVC expertise with best practices and tips shared from recognized industry experts. This book takes the reader on a 16-chapter long journey towards being a better ASP.NET MVC developer with chapter 16 putting all information covered in practical context by dissecting the implementation of Nuget.org, a real-life open-source, ASP.NET MVC project.  All code samples referenced in this book are conveniently accessible via NuGet, a free, open-source Library package manager that installs as a Visual Studio Extension. Chapters 2, 3 and 4 thoroughly cover MVC’s various components: Controllers “C”, Views “V” and Models “M” respectively. Chapter 5 covers additional extension methods (Helpers) provided to speed and ease the use of common HTML elements such as forms, textboxes, grids, to name a few… Chapter 6 tackles built-in validation while providing examples and use cases on implementing custom validation that plugs into the MVC framework. Chapters 7 thru 13 discusses the latest on Membership, Ajax, Routing, NuGet and the ASP.Net Web API. Chapters 12 (Dependency Injection) and 13 (Unit Testing) demonstrate a big competitive advantage of MVC with its ease of test-ability and plug-ability. Chapters 14 and 15 targets the advanced developer showcasing how to extend MVC to customize and replace every piece in the framework.In conclusion, I strongly recommend Professional ASP.NET MVC 4 as an excellent read for both developers already using MVC as well as those getting started with the framework.   Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group.  You can access my reviews of books I recently read: Professional ASP.NET Design Patterns Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

• Why are there two types of Adobe Flash Player download / update?

  - by w3d

  Adobe Flash Player checks for updates at startup. If updates are required the Adobe dialog pops up with a [Download] button. Usually when I hit the [Download] button it downloads it straight away with a progress bar that zips across the dialog. I then get the option to install it. All good. However, sometimes when I hit the [Download] button it takes me to the website: https://get3.adobe.com/flashplayer/update/plugin/ Which presents me with an [Update now] button (and to install McAfee!). What is this for? Why didn't it download and install in the "usual" way? So, why are there apparently two different update methods for what appears to be the same thing? One is nice and swish and integrated into the updater, the other more long winded. In fact, I don't [Update now] when it takes me to the website, because I'm like "Hey, what's this?!"

• How secure is Microsoft 2007's encryption?

  - by ericl42

  I've read some various articles about Microsoft's encryption, and from what I gather, 2007 is secure using all default options due to it using AES, and 2000 and 2003 can be configured secure by changing the default algorithm to AES. I was wondering if anyone else has read any other articles or know of any specific vulnerabilities involved with how they implement the encryption. I would like to be able to tell users that they can use this to send semi sensitive documents as long as they use AES and a strong password. Thanks for the information.

• You wouldn&rsquo;t drink 9 year old milk would you?

  - by Jim Duffy

  This is an absolutely brilliant campaign to urge users that its time to move on from IE 6. I like how it puts it terms that everyone can understand and has probably experienced at one time or another. How many times have you opened the milk, took a sniff, and experienced that visceral reaction that accompanies catching a whiff of milk that has turned to the dark side of the force? I call it Darth Vader milk. :-) Of course I’m assuming that you haven’t used IE 6 for a long time now. It is our responsibility as information technology workers to communicate to our friends and family how lame using IE 6 is. Shame them into upgrading if necessary. I don’t care how you get through to them but get through. Tell them that only losers use IE 6. Tell them you’ll cut them out of the your will. Tell them they’re banned from your annual BBQ blowout. Tell them that [insert their favorite celebrity’s name here] thinks people using IE6 are losers.  :-) Seriously, IE6 sucks and blows at the same time and has got to go for a number of reasons including the security leaks that come with using it. Confidentially, I urge them to upgrade for purely selfish reasons. Because I am the first level of computer support for waaaaaay to many of my family members I always advocate they use a current browser (IE 8 or Firefox) and anti-virus software (AVG). Call me selfish but I’d rather not waste my time dealing with a virus or malware that could potentially slip through with IE6. Yes, I’m selfish with my time that way. :-) Have a day. :-|

• What can be done against language inertia?

  - by gerrit

  Often, projects use programming language X, but would use programming language Y if they were started from scratch. For example, big numerical models may be written entirely in Fortran. Whereas this might be a reasonable choice for the components that need to run fast (alternative would be C or C++), it might be a poor choice for components that either do not need to run fast (such as things dealing with human input or simple visualisations), or where runtime is not the limiting factor (such as I/O, particularly when from the network). Another example may be when a project is built using a propriety language (such as Matlab; no, FOSS clones are not good enough) and was started at a time when FOSS alternatives were not viable, but ten years later, they are; and it would be beneficial to migrate. However, due to language inertia, a migration does not happen. Code that works should not be touched, porting code is a time-consuming, expensive process, and programmers are familiar in language X but not necessarily in language Y. Still, in the long term, a migration would likely be beneficial. Can anything be done to mitigate the problems associated with language inertia? Are there any notable examples of big projects that have successfully overcome this problem? Or is a project bound to stick forever with the initial choices?

• How do you troubleshoot Family Safety reports

  - by Klas Mellbourn

  I have set up Microsoft Family Safety in Windows 8 for my daughter's account. At first I got meaningful reports via e-mail each week. But then the e-mails started reporting no activity, even though my daughter still uses the computer. The e-mails are still sent to me, but indicate that she is not using the computer at all. Family Safety is definitely still active on the computer. It limits how long she can use the computer. So only the e-mail reports are buggy. I don't know how to troubleshoot this since the e-mails are generated by Microsoft. Any ideas?

• Mapping an sFTP connection to a Windows drive?

  - by Nicolas

  I'm looking for a way to map an sFTP connection to a Windows (Vista) drive. In other words, a tool that would add a new drive (let's say N:) to my computer, that would directly point to my remote server via sFTP. That way, "N:\my_dir\file.txt" would actually be something like "/home/user/my_dir/file.txt" on the remote server. Reading the file on Windows would download it, and writing content in it would upload it...network transfers being made via sFTP. I'm aware of Novell NetDrive, but it has various issues with long filenames, and seems to corrupt UTF-8 files content depending on the BOM. Do you know about any reliable alternative ? Thanks ! Edit : I have complete control of the remote server, except that it's remote enough for me not to be able to physically access it.

• Dual boot on Hp Envy Ultrabook

  - by phodu_insaan

  I just bought a HP Envy ultrabook 1002TX. It comes with a Win7 Home basic and a 32GB SSD + 500GB HDD. I started to install ubuntu and in doing so went and deleted all the partitions on my HDD and recreated them the way I wanted. Then when I tried to install ubuntu it didn't recognize my HDD. To solve this i typed dmraid -E -r /dev/sdX where the 'X' was my SSD drive. After this ubuntu can install but windows for some reason does not install. Also the Intel Caching feature is lost and SSD is just sitting and doing nothing. I want to know how to solve this problem. Ideeally I would like to use the SSD for caching, either in windows or ubuntu. How do I get the SSD back to working as an Intel rapid cache? How do I get windows to install properly? It tell me that windows is unable to configure itself to my hardware, and my PC came with windows pre-installed so this is not possible. Sorry for the long question and thanks for your answers! PS: At one time when I booted I pressed Ctrl+i and went to the intel rapid cache menu. I think i screwed up something in here, because only after this the rapid cache stopped working, and each time I booted the PC thought the BIOS was my primary disk.

• FreeDOS reinstallation -- accidental script change

  - by jerry2144

  I'm extremely new to FreeDOS and I got a new HP desktop computer with the FreeDOS operating system. I messed up and accidentally changed its scripts and messed around with it's boot order. Long story short, I'm getting a disk error when I boot up. I believe I need to just reinstall FreeDOS and all should be good, but I want to get someone's opinion with much more experience than my own. Also, if someone could guide me through the installation process using a DVD installer that would be amazing. I have already downloaded the FreeDOS iso image and unzipped it. I don't know what I need to do now though. Should I even have unzipped it?

• ADF Faces Skin Editor - How to Work with It

  - by Shay Shmeltzer

  The ODTUG Kscop11 conference was a great success with lots of sessions about FMW running in a special track. I did several sessions and labs in the conference, and I thought it might be a good idea to at least give you a taste of what you might have missed. So here is most of what I demoed in my ADF Faces Skinning session (not all though - that session was 60 minutes long, and while everyone did end up going out of the building in the middle because of a fire drill for about 5 minutes, there was other things covered in the session as well). In the demo here you'll see how to generate new images and default color scheme, how to identify a component class with Firebug, how to skin a component, how to identify the global selector of a property, how to change fonts and how to change strings. By the way, for more on ADF Skinning you should also listen to the ADF Insider seminar that Frank Nimphius recorded on skinning, it will give you better understanding of the overall skinning process. P.S. in the demo I add an entry to the web.xml file which prevent ADF Faces from compressing the HTML that is generated. The entry is for org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION  and I set it to true. This is very useful when you work on creating the skin, but don't forget to un-set it before you go production.

• Adventures in Lab Management Configuration: Part 3 of 3

  - by Enrique Lima

  This is long overdue.  But here it is. In the previous two sections I have discussed on how I got a CMMI v4.2 to take on the same fields as v5 and therefore be able to communicate with MTM and Lab Manager.  And that was quite a success. Yet when I opened up Lab Management while it was fully aware of the VMs being there, it refused to let me enroll them into an environment.  It kept stating there was no suitable host to deploy the VM to, error TF259115. This was an indication something was not matching the expected network configuration between TFS and Hyper-V/SCVMM. So, here are a couple of things that took place: Verified the network segment specified for network isolation matched what was configured physically for either DHCP or manually assigned IP addressing for the guest VMs Made sure TFS was fully aware of the configuration settings for the network location name.  For that I issued:  tfsconfig lab /settings /networklocation:”<name of the network location configured in SCVMM” On that last item, that was key to making sure Lab Management communicated with the VMs and for it to allow enrollment into the new Virtual Environment.

• Failed Project: When to call it?

  - by Dan Ray

  A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

• auspex LFS backups

  - by user1250465

  I have some backup tapes which existed on an AUSPEX file server. The backups were written to tape with the SunOs version of the CPIO command. Now that I need to restore them, (of course there are no more auspex servers in existance), the backups won't restore because the headers are not standard. I have dumped the tape images to disk. PAX, CPIO, and TAR cannot read the images. I've tried all of the CPIO format options. The errors I get are "name too long", "byte swapped in header", or just junk output. I can open up the images and read the contents of the files, but cannot restore the images. I have found that SunOs had a special header in CPIO V2.5 images. I have found the source for cpio, now I need definition of the SunOs header inside CPIO?

• How to be hired as a remote programmer abroad and not to be an entrepreneur?

  - by user592704

  The question is quite interesting as for me because I watched jobs adds and mostly they all: A) Require being located the same country a vacancy is B) Employers don't want to hire foreign programmers if they don't have H1B or something C) As a rule, most adds provide 6 month contract position I can keep adding the list for long time describing some job adds specifications, anyway, as a rule, most positions require non-employee cooperation status. I don't have a company for such kind of "making projects by a client order" so it is quite complicated; So I was trying, just, as for a statistics, to find out is there a way to be hired abroad as a remote programmer as if I get hired in my native city? The thing is not about being hired where I can be hired "because I am located this or that place" but the thing is about a possibility (not to relocate) which actually should provide nowadays technologies especially for IT specialists in many different fields; So the question is it possible to work any country in remote mode as if I am working in my own place? What do I need for that? Can you advice some useful web sites in this direction? If you can share your own experience I'd love to listen to. Any useful advices are much appreciated

• Background process text appears in terminal vim

  - by Jezen Thomas

  First time poster, long time lurker, searched, couldn’t find etc, etc. I’m running vim in tmux, in iTerm2. I’m running a server with Grunt.js, which I have running in the background, out of my way. I start my grunt server in the background like this: grunt server & Grunt also watches a bunch of files, and runs some tasks when any of the watched files have been written to. The problem is, when I am in vim and I write a file, the output from grunt starts rendering in vim! Here are some screenshots to illustrate the problem: Before writing the file: And after writing the file: What have I tried? I’ve tried running a ‘stock’ vim by starting with this: vim -u NONE …But the problem remains. This suggests to me that the problem is not with my .vimrc. Perhaps it’s an issue with iTerm2, I don’t know. Help.

• Find non-ascii characters from a UTF-8 string

  - by user10607

  I need to find the non-ASCII characters from a UTF-8 string. my understanding: UTF-8 is a superset of character encoding in which 0-127 are ascii characters. So if in a UTF-8 string , a characters value is Not between 0-127, then it is not a ascii character , right? Please correct me if i'm wrong here. On the above understanding i have written following code in C : Note: I'm using the Ubuntu gcc compiler to run C code utf-string is xvab c long i; char arr[] = "xvab c"; printf("length : %lu \n", sizeof(arr)); for(i=0; i<sizeof(arr); i++){ char ch = arr[i]; if (isascii(ch)) printf("Ascii character %c\n", ch); else printf("Not ascii character %c\n", ch); } Which prints the output like: length : 9 Ascii character x Not ascii character Not ascii character ? Not ascii character ? Ascii character a Ascii character b Ascii character Ascii character c Ascii character To naked eye length of xvab c seems to be 6, but in code it is coming as 9 ? Correct answer for the xvab c is 1 ...i.e it has only 1 non-ascii character , but in above output it is coming as 3 (times Not ascii character). How can i find the non-ascii character from UTF-8 string, correctly. Please guide on the subject.

• Hosting and domain registrations for multiple clients under a single hosting account of mine?

  - by letseatfood

  I am finally getting regular work designing, developing, and deploying websites for small businesses and individuals. So far the websites utilize single-user content management systems, so the websites create, as far as I know, minimal load on the shared servers. I have always required that each of my clients purchase annual shared hosting at Dreamhost. For domain registration, I ask that they register with Dreamhost, but some already have a registered domain elsewhere and this is fine with me. I do this so the billing issues are the client's responsibility, not mine. My question is: Since I can register unlimited domains and connect them to my one shared hosting account at Dreamhost, should I not be requiring clients to individually pay for shared hosting and a domain? Should I actually be paying for one hosting account and then hosting all of my client's websites on that account? As I said before, I currently have each client buy their own hosting, because I feel that, for example, if there is high traffic to their site, there would be less a chance of the site going down than if their site was hosted with many others on one account. I am famous for being long-winded, please let me know if I can clarify at all. Thanks!

• How to refactor when all your development is on branches?

  - by Mark

  At my company, all of our development (bug fixes and new features) is done on separate branches. When it's complete, we send it off to QA who tests it on that branch, and when they give us the green light, we merge it into our main branch. This could take anywhere between a day and a year. If we try to squeeze any refactoring in on a branch, we don't know how long it will be "out" for, so it can cause many conflicts when it's merged back in. For example, let's say I want to rename a function because the feature I'm working on is making heavy use of this function, and I found that it's name doesn't really fit its purpose (again, this is just an example). So I go around and find every usage of this function, and rename them all to its new name, and everything works perfectly, so I send it off to QA. Meanwhile, new development is happening, and my renamed function doesn't exist on any of the branches that are being forked off main. When my issue gets merged back in, they're all going to break. Is there any way of dealing with this? It's not like management will ever approve a refactor-only issue so it has to be squeezed in with other work. It can't be developed directly on main because all changes have to go through QA and no one wants to be the jerk that broke main so that he could do a little bit of non-essential refactoring.

• "No such file or directory" when the file is there

  - by Arlaud Agbe Pierre

  I'm trying to run XPDF on a linux (probably red hat) OVH shared server. I've managed to have ftp ssh access and put the 64 bits binaries onto a folder. The problem is : even though the files are there with the right permissions, if I try running it I'm getting a file not found problem (I'm thinking about a missing link..) Long story short : jurisedi@ssh1:~/xpdf$ file pdftotext pdftotext: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), stripped jurisedi@ssh1:~/xpdf$ ./pdftotext -ovh: jurisedi@ssh1:~/xpdf$: No such file or directory Any ideas ?
