  • What is the economic rationale behind programmers who work on a open source project (free) instead of a commercial project (not free)?

    - by Kim Jong Woo
    I can't understand why some people dedicate so much hour into a completely open source project without closing it and yielding greater profit from it. I don't think profiting from your code is evil, I think it's a great motivator. Why do some people feel that commercial software and generating money from it is bad? There seems to be this black and white thinking that open source = good, commercial = bad. I hardly find this convincing, and often commercial companies which are supported by sales produce very good results. An open source software in the same niche can't compete against the corporation. Of course, sometimes this is completely the other way around where private companies produce inferior product compared to open source counterparts. So help me understand, why do programmers open source their code when there is commercial prospects for it? Shouldn't the rational programmer or human being make every effort to capitalize on their opportunity cost? Working on a open source project for months when you could've spent the same number of hours at commidity wage or some other monetary compensation?

  • Can I delete libc-bin?

    - by Balazs Szikszay
    Question is simple, I need to know because I cant upgrade/install anything, because it always says I have to uninstall/delete it to continue. It also says dont do it, if I dont know what I am doing. EDIT: szikszay@szikszay-Latitude-E5530-non-vPro:~$ sudo apt-get upgrade Reading package lists...

  • Mac OS X 10.6 issues connecting via vpn to Microsoft server

    - by chris hough
    I am currently running Mac OS X Snow Leopard and trying to use the native vpn client to connect to our Microsoft vpn server. If I route all traffic via the vpn connection I am able to connect to our servers, however, external traffic to i.e. google or stack overflow is blocked. If I uncheck the checkbox to route all traffic via the vpn I can connect to the vpn, however, I can not connect to my servers, external traffic to google or stackoverflow works though. Is this a vpn client issue, do I need to purchase Mac OS X vpn software instead of the native client, or is there a Microsoft vpn server setting that has to be checked. I am not familiar with the server software, but I wanted to post this question here to help out our network admin with the Mac OS X machines.

  • Does an alternative to regedit.exe exist?

    - by Peter Mortensen
    Is there something better than regedit.exe for searching and editing the Windows registry? Update 1: Registrar Registry Manager 6.50 from Resplendence Software Projects, free lite edition meets the two requirements listed below. Direct download URL (2.7 MB). Search can also be restricted to a particular branch in the registry. However exporting and sorting on columns in the search window is disabled in the lite version (and there may be other limitations). I haven't yet evaluated the other candidates. In particular I would like to be able to batch search instead of having to step through with F3. And a go to function that will open a particular registry key, e.g. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer, instead of having to go through from the top, Platform: Windows XP.

  • Display a Text Message During Bootup of Windows 7

    - by Mysticgeek
    Sometimes you might want to leave a text message for a user before they log into a Windows 7 computer. Today we show you a neat trick that allows you to leave a message they can read before logging in. Add a Text Message To add a message, click on Start and enter regedit into the Search box and hit Enter. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\System and double-click on legalnoticecaption. In the Value data field enter in the header you want…for instance your company name or the name of your computer…whatever you want it to be, then click OK. Then double-click on legalnoticetext … And in the Value data field enter in the message you want to display and click OK. Close out of Registry Editor and reboot the computer.   After the machine reboots you’ll see the text message you just created at the Welcome screen.   You can include whatever text message you want to be included for the user to read before they log in. This is a neat trick if you have a company or school and want to show a particular message to the user before they log into the machine.

  • Your Job Search Should be More Than Just a New Year's Resolution

    - by david.talamelli
    I love the beginning of a new year, it is a great chance to refocus and either re-evaluate goals you are working to or even set new ones. I don't have any statistics to measure this but I am sure that one of the more popular new year's resolutions in the general workforce is to either get a new job or work to further develop one's career. I think this is a good idea, in today's competitive work force people should have a plan of what they want to do, what role they are after and how to get there. One common mistake I think many people make though is that a career plan shouldn't be a once a year thought. When people finish with the holiday season with their new year's resolution to find a new job fresh in their mind, you can see the enthusiasm and motivation a person has to make something happen. Emails are sent, calls are made, applications are made, networking is happening, etc..... Finding the right role that you are after however can be difficult, while it would be great if that dream role was available just at the time you happened to be looking for it - in reality this is not always the case. Job Seekers need to keep reminding themselves that while sometimes that dream job they are after is available at the same time they are looking, that also a Job search can be a difficult and long process. Many people who set out with the best of intentions in January to find a new job can soon lose interest in a job search if they do not immediately find a role. Just like the Christmas decorations are put away and the photos from New Year's are stored away - a Job Seeker's motivation may slowly decrease until that person finds themselves 12 months later in the same situation in same role and looking for that new opportunity again. Rather than just "going for it" and looking for a role in the month of January, a person's job search or career plan should be an ongoing activity and thought process that is constantly updated and evaluated over the course of the year. It can be hard to stay motivated over an extended period of time, especially when you are newly motivated and ready for that new role and the results are not immediate. Rather than letting your job search fall down the priority list and into the "too hard basket" a few ideas that may keep your enthusiasm fresh Update your resume every 6 months, even if you are not looking for a job - it is easy to forget what you have accomplished if you don't keep your details updated. Also it is good to be prepared and have a resume ready to go in case you do get an unexpected phone call for that 'dream job' you have been hoping for. Work out what you want out of your next role before you begin your job search - rather than aimlessly searching job ads or talking to people - think of the organisations or type of role you would like before you search. If you know what you are looking for it will be much easier to work out how to get there than if you do not know what you want. Don't expect immediate results once you decide to look for another job, things don't always fall into place. Timing and delivery can be important pieces of being selected for a role, companies don't hire every role in January. Have an open mind - people you meet or talk to may not result in immediate results for your job search but every connection may help you get a bit closer to what you are after . These actions will not guarantee a positive result, but in today's competitive work force every little of extra preparation and planning helps. All the best for 2011 and I hope your career plan whatever it may be is a success.

But I soon get messages like these in the Apache logs: [Wed Sep 02 23:16:34 2009] [warn] (103)Software caused connection abort: mod_fcgid: ap_pass_brigade failed in handle_request function [Wed Sep 02 23:16:35 2009] [warn] (103)Software caused connection abort: mod_fcgid: ap_pass_brigade failed in handle_request function and then Apache doesn't seem to recognize that all its processes are dead (I have a max of 5 backends) and refuses to spawn new ones: [Wed Sep 02 23:26:16 2009] [notice] mod_fcgid: /var/www/hacks.og.theinfo.org/picker.fcgi total process count 5 >= 5, skip the spawn request [Wed Sep 02 23:26:17 2009] [notice] mod_fcgid: /var/www/hacks.og.theinfo.org/picker.fcgi total process count 5 >= 5, skip the spawn request at which point it refuses to respond to requests from the outside world. This doesn't seem to happen with my other FastCGIs, which all use the same Apache config: <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi IPCConnectTimeout 20 MaxProcessCount 5 DefaultMaxClassProcessCount 2 DefaultMinClassProcessCount 1 </IfModule> Any idea what causes it?

  • Weird canvas/page size printing problem in Adobe Acrobat

    - by Justin
    I am trying to print a document in Adobe Acrobat. For some reason, Acrobat wants to print my document smaller than it actually is, despite having chosen that I DO NOT want the image to be scaled: http://www.freeimagehosting.net/image.php?945fbb3f41.png See the grey area on the top and left of the preview? That's the area that's getting cut off. Notice that the whole preview (INCLUDING the gray areas) is 8.5x11 in. Also look at the paper size, a nice 8.5x11 in. This happens for any real printer I connect to my computer. However, printing to a "fake" software printer is not a problem: Printing to a software printer: Use the above link but change the image name to this: 769eaf59ab.png Any ideas? I've tried messing with the paper sizes but no luck. I can't use "Shrink to printable area" because ultimately I'm doing this to print to a preprinted form (the same issue occurs when I select "Form fields only" but this demonstrates it better).

  • Strange. Asterisk key plays random Windows sound when pressed

    - by Charles
    This is a new one on me. When I press the "asterisk", or * button on my number pad (but not SHIFT+8), Windows makes either a "Exclamation" or "Windows ding" sound. I haven't noticed a pattern to which sound is made. Logitech K200 keyboard No special key mapping software or Logitech software running Realtek sound to stereo through optical cable. Visual Studio 2010, Chrome, Fiddler, WinRAR, Notepad++, and Dropbox running. No unusual behavior otherwise. A solution isn't terribly important but my curiosity is both piqued and stumped. This doesn't normally happen and nothing odd has taken place otherwise. Ideas?

  • Choice of open source license for some components, closed source for others

    - by Peter Serwylo
    G'day, I am working on a set of multiplayer games, where different games play against each other (e.g. you play a Tetris clone, I play an Asteroids clone, but we are both competing against each other). All the games would be based on the same underlying framework written specifically for this project. I am struggling to comprehend how I would license this so that: The underlying framework is open source, so other people can create new games based on it. Some games built on the framework are open source Other games are closed source The goal is to have two bundles on something like the Android market: One free and open source package which has a collection of games Another "premium" (although I dislike that word) paid package which has a different collection of games. Usually I am fond of permissive licenses such as MIT/BSD, however I would prefer something more in the vein of the GPL for this. This is because for software such as the snes-9x SNES emulator, which is a great piece of software, there is a ton of poor quality versions being sold, whereas it would be preferable if there was just one authoritative version which was always kept up to date, and distributed for free. If the underlying framework was GPL'd, would I be able to build closed source games on top of it? Thanks for your input.

  • OSX 10.6.6 SSH md5 break-in check

    - by Alex
    Information Recently one of the linux servers that I access was compromised to steal passwords and ssh keys using a modified ssh binary. This lead me to question if the attacker had compromised my OSX Laptop which had ssh access turned on. A sophos virus scan turned up nothing, and I did not have rkhunter installed before the attack, so I could not compare hashes of the system binaries to be sure. However because OSX is relatively standard for each of their major releases, I asked fiends for md5 hashes md5 /usr/bin/ssh and md5 /usr/sbin/sshd as a basic first check to see if there was anything different about my machine. A few emails later I have found the following data: Version (Arch) [N] MD5 (/usr/bin/ssh) MD5 (/usr/sbin/sshd) OSX 10.5.8 (PPC) [3] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.5.8 (intel) [5] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.6.x (intel) [7] 591fbe723011c17b6ce41c537353b059 e781fad4fc86cf652f6df22106e0bf0e OSX 10.6.x (intel) [4] 58be068ad5e575c303ec348a1c71d48b 33dafd419194b04a558c8404b484f650 Mine 10.6.6 (intel) df344cc00a294c91230c65e8b7332a79 b5094ccf4cd074aaf573d4f5df75906a where N is the number of machines with with that MD5, and the last row is my laptop. The sample is relatively heterogeneous spaning a few years of different makes and models of Apples, and different versions of 10.6.x. The different hash for my system made me worried that these binaries might have been compromised. So I made sure that my backup for the week was good, and dived into formatting my system and reinstalling OSX. After reinstalling OSX from the manufacturer DVD, I found that the MD5 hash did not change for either ssh, or sshd. Goal Make sure that my system is does not have any malicious software. Should I be worried that this base install of OSX (with no other software installed) has been compromised? I have also updated my system to 10.6.6 and found no change as well. Other Information I am not sure if this is helpful information, but my laptop is a i7 15 inch MacBook Pro bought in Nov 2010, and here is some output from system_profiler: System Software Overview: System Version: Mac OS X 10.6.6 (10J567) Kernel Version: Darwin 10.6.0 64-bit Kernel and Extensions: No Time since boot: 1:37 Hardware: Hardware Overview: Model Name: MacBook Model Identifier: MacBook6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Sudden Motion Sensor: State: Enabled On the laptop, I find: $ codesign -vvv /usr/bin/ssh /usr/bin/ssh: valid on disk /usr/bin/ssh: satisfies its Designated Requirement $ codesign -vvv /usr/sbin/sshd /usr/sbin/sshd: valid on disk /usr/sbin/sshd: satisfies its Designated Requirement $ ls -la /usr/bin/ssh -rwxr-xr-x 1 root wheel 1001520 Feb 11 2010 /usr/bin/ssh $ ls -la /usr/sbin/sshd -rwxr-xr-x 1 root wheel 1304800 Feb 11 2010 /usr/sbin/sshd $ ls -la /sbin/md5 -r-xr-xr-x 1 root wheel 65232 May 18 2009 /sbin/md5 Update So far I have not gotten an answer about this question, but if you could help by increasing the number of hashes that I can compare against, that would be great. To get hashes, and version numbers, run the following on osx: md5 /usr/bin/ssh md5 /usr/sbin/sshd ssh -V sw_vers

  • How to remove HDD Low virus

    - by samsudeen
    “HDD Low virus” is a new  fake system optimizer application which started affecting all  the Windows ( XP, vista, Windows 7) based computers world wide starting from Monday.

  • Can't write to NTFS formatted drives

    - by mloman
    I'm not sure what has happened, but I've all of a sudden lost write access to any of my NTFS external drives. I installed a few games and apps from the software center, and now I can't make new folders or copy and paste files to anything that is NTFS. Everything is now read only, and I've tried so many things to fix it, but it seems hopeless. Just to check if it wasn't the drives themselves, I made a little ntfs formatted truecrypt volume, and a fat formatted volume. And yes, it seems that Ubuntu is blocking me from writing anything to NTFS. What happened here? Whats a way I can simply get write access to my NTFS drives, so I can just backup all my stuff. I'll probably reinstall Ubuntu. Please help. UPDATE (and thanks everyone for their quick replies) The problem has been solved. Prior to noticing that I had lost NTFS write permission, I had installed GParted from the software center, and there was an extension called ntfsprogs that came with it. During my search for a solution to the problem, I uninstalled GParted (as that was one of the apps I installed just before the problem). But that did not solve the problem. I came across an app called 'NTFS Configuration Tool'. When I installed this, it said that the ntfsprogs extension needed to be removed (so I guess uninstalling GPARTED, didn't remove the ntfsprog extension). I launched the NTFS Configuration Tool and now I have write access to NTFS drives. Unfortunately, I didn't check if I had write permission prior to launching the NTFS Configuration Tool, so I'm not sure whether the NTFS Configuration Tool, or the un-installation of ntfsprog gave me back NTFS write permission. Hopefully if another newbee encounters this problem, they'll come across this page and know what to do.

  • How can I set up multiple dynamic users to update a single network's dynamic IP

    - by d3vid
    On my home network we are allocated a dynamic IP. I want to configure ddclient (or an equivalent) to send IP updates to DNS-O-Matic/OpenDNS only when I am on my home network. I do not want to send IP updates when I'm on my office network. Can this be done? I am prepared to use different FLOSS software or a different free DNS service. Additionally, there are multiple users who may be on the home network or away on other networks. How can we configure ddclient on each machine so that whoever is on the home network updates the IP (i.e. so we don't have to rely on a particular machine being on the network to update the IP). OpenDNS support have said we can't simply install updater software on each machine.

  • SQL SERVER – An Efficiency Tool to Compare and Synchronize SQL Server Databases

    - by Pinal Dave
    There is no need to reinvent the wheel if it is already invented and if the wheel is already available at ease, there is no need to wait to grab it. Here is the similar situation. I came across a very interesting situation and I had to look for an efficient tool which can make my life easier and solve my business problem. Here is the scenario. One of the developers had deleted few rows from the very important mapping table of our development server (thankfully, it was not the production server). Though it was a development server, the entire development team had to stop working as the application started to crash on every page. Think about the lost of manpower and efficiency which we started to loose.  Pretty much every department had to stop working as our internal development application stopped working. Thankfully, we even take a backup of our development server and we had access to full backup of the entire database at 6 AM morning. We do not take as a frequent backup of development server as production server (naturally!). Even though we had a full backup, the solution was not to restore the database. Think about it, there were plenty of the other operations since the last good full backup and if we restore a full backup, we will pretty much overwrite on the top of the work done by developers since morning. Now, as restoring the full backup was not an option we decided to restore the same database on another server. Once we had restored our database to another server, the challenge was to compare the table from where the database was deleted. The mapping table from where the data were deleted contained over 5000 rows and it was humanly impossible to compare both the tables manually. Finally we decided to use efficiency tool dbForge Data Compare for SQL Server from DevArt. dbForge Data Compare for SQL Server is a powerful, fast and easy to use SQL compare tool, capable of using native SQL Server backups as metadata source. (FYI we Downloaded dbForge Data Compare) Once we discovered the product, we immediately downloaded the product and installed on our development server. After we installed the product, we were greeted with the following screen. We clicked on the New Data Comparision to start our new comparison project. It brought up following screen. Here is the best part of the product, we just had to enter our database connection username and password along with source and destination details and we are done. The entire process is very simple and self intuiting. The best part was that for the source, we can either select database or even backup. This was indeed fantastic feature. Think about this, if you have a very big database, it will take long time to restore on the server. Once it is restored, you will be able to work with it. However, when you are working with dbForge Data Compare it will accept database backup as your source or destination. Once I click on the execute it brought up following screen where it displayed an excellent summary of the data compare. It has dedicated tabs for the what is changing in what table as well had details of the changed data. The best part is that, once we had reviewed the change. We click on the Synchronize button in the menu bar and it brought up following screen. You can see that the screen has very simple straight forward but very powerful features. You can generate a script to synchronize from target to source or even from source to target. Additionally, the database is a very complicated world and there are extensive options to configure various database options on the next screen. We also have the option to either generate script or directly execute the script to target server. I like to play on the safe side and I generated the script for my synchronization and later on after review I deployed the scripts on the server. Well, my team and we were able to get going from our disaster in less than 10 minutes. There were few people in our team were indeed disappointed as they were thinking of going home early that day but in less than 10 minutes they had to get back to work. There are so many other features in  dbForge Data Compare for SQL Server, I am already planning to make this product company wide recommended product for Data Compare tool. Hats off to the team who have build this product. Here are few of the features salient features of the dbForge Data Compare for SQL Server Perform SQL Server database comparison to detect changes Compare SQL Server backups with live databases Analyze data differences between two databases Synchronize two databases that went out of sync Restore data of a particular table from the backup Generate data comparison reports in Excel and HTML formats Copy look-up data from development database to production Automate routine data synchronization tasks with command-line interface Go Ahead and Download the dbForge Data Compare for SQL Server right away. It is always a good idea to get familiar with the important tools before hand instead of learning it under pressure of disaster.

  • Common mistakes which lead to corrupted invariants

    - by Dave B.
    My main source of income is web development and through this I have come to enjoy the wonders of programming as my knowledge of different languages has increased over the years through work and personal play. At some point I reached a decision that my college education was not enough and that I wanted to go back to school to get a university degree in either computer science or software engineering. I have tried a number of things in my life and it took me a while before I found something that I feel is a passion and this is it. There is one aspect of this area of study that I find throws me off though. I find the formal methods of proving program correctness a challenge. It is not that I have trouble writing code correctly, I can look at an algorithm and see how it is correct or flawed but I struggle sometimes to translate this into formal definitions. I have gotten perfect or near perfect marks on every programming assignment I have done at the college level but I recently got a swath of textbooks from a guy from univeristy of waterloo and found that I have had trouble when it comes to a few of the formalisms. Well at this point its really just one thing specifically, It would really help me if some of you could provide to me some good examples of common mistakes which lead to corrupted invariants, especially in loops. I have a few software engineering and computer science textbooks but they only show how things should be. I would like to know how things go wrong so that it is easier to recognize when it happens. Its almost embarrassing to broach this subject because formalisms are really basic foundations upon which matters of substance are built. I want to overcome this now so that it does not hinder me later.

  • How to get the mic on the Creative X-Mod soundcard working correctly?

    - by Nyamiou The Galeanthrope
    Well, I have this problem for a while now. When my computer start the mic seem to work but it's like it's muted. I have to go to a terminal and type alsamixer -c 1 and then I set up PCM Capture Source on Line and set up it back to Mic to get the mic actually working. Is there is a way to do this automatically or to solve the problem. I use a special workaround on this card because of the bug #429642. My workaround is having this at the end of my /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf : [Mapping xmod-stereo-out] device-strings = surround51:%f description = Analog Stereo Creative Xmod channel-map = front-left,front-right paths-output = analog-output analog-output-headphones analog-output-mono analog-output-lfe-on-mono paths-input = analog-input analog-input-mic analog-input-linein analog-input-aux analog-input-video analog-input-tvtuner analog-input-fm analog-input-mic-line priority = 10 Maybe the bug come from here, maybe I have to change something. Thank you for any help.

  • The future for Microsoft

    - by Scott Dorman
    Originally posted on: http://geekswithblogs.net/sdorman/archive/2013/10/16/the-future-for-microsoft.aspxMicrosoft is in the process of reinventing itself. While some may argue that it’s “too little, too late” or that their growing consumer-focused strategy is wrong, the truth of the situation is that Microsoft is reinventing itself into a new company. While Microsoft is now calling themselves a “devices and services” company, that’s not entirely accurate. Let’s look at some facts: Microsoft will always (for the long-term foreseeable future) be financially split into the following divisions: Windows/Operating Systems, which for FY13 made up approximately 24% of overall revenue. Server and Tools, which for FY13 made up approximately 26% of overall revenue. Enterprise/Business Products, which for FY13 made up approximately 32% of overall revenue. Entertainment and Devices, which for FY13 made up approximately 13% of overall revenue. Online Services, which for FY13 made up approximately 4% of overall revenue. It is important to realize that hardware products like the Surface fall under the Windows/Operating Systems division while products like the Xbox 360 fall under the Entertainment and Devices division. (Presumably other hardware, such as mice, keyboards, and cameras, also fall under the Entertainment and Devices division.) It’s also unclear where Microsoft’s recent acquisition of Nokia’s handset division will fall, but let’s assume that it will be under Entertainment and Devices as well. Now, for the sake of argument, let’s assume a slightly different structure that I think is more in line with how Microsoft presents itself and how the general public sees it: Consumer Products and Devices, which would probably make up approximately 9% of overall revenue. Developer Tools, which would probably make up approximately 13% of overall revenue. Enterprise Products and Devices, which would probably make up approximately 47% of overall revenue. Entertainment, which would probably make up approximately 13% of overall revenue. Online Services, which would probably make up approximately 17% of overall revenue. (Just so we’re clear, in this structure hardware products like the Surface, a portion of Windows sales, and other hardware fall under the Consumer Products and Devices division. I’m assuming that more of the income for the Windows division is coming from enterprise/volume licenses so 15% of that income went to the Enterprise Products and Devices division. Most of the enterprise services, like Azure, fall under the Online Services division so half of the Server and Tools income went there as well.) No matter how you look at it, the bulk of Microsoft’s income still comes from not just the enterprise but also software sales, and this really shouldn’t surprise anyone. So, now that the stage is set…what’s the future for Microsoft? The future I see for Microsoft (again, this is just my prediction based on my own instinct, gut-feel and publicly available information) is this: Microsoft is becoming a consumer-focused enterprise company. Let’s look at it a different way. Microsoft is an enterprise-focused company trying to create a larger consumer presence.  To a large extent, this is the exact opposite of Apple, who is really a consumer-focused company trying to create a larger enterprise presence. The major reason consumer-focused companies (like Apple) have started making in-roads into the enterprise is the “bring your own device” phenomenon. Yes, Apple has created some “game-changing” products but their enterprise influence is still relatively small. Unfortunately (for this blog post at least), Apple provides revenue in terms of hardware products rather than business divisions, so it’s not possible to do a direct comparison. However, in the interest of transparency, from Apple’s Quarterly Report (filed 24 July 2013), their revenue breakdown is: iPhone, which for the 3 months ending 29 June 2013 made up approximately 51% of revenue. iPad, which for the 3 months ending 29 June 2013 made up approximately 18% of revenue. Mac, which for the 3 months ending 29 June 2013 made up approximately 14% of revenue. iPod, which for the 3 months ending 29 June 2013 made up approximately 2% of revenue. iTunes, Software, and Services, which for the 3 months ending 29 June 2013 made up approximately 11% of revenue. Accessories, which for the 3 months ending 29 July 2013 made up approximately 3% of revenue. From this, it’s pretty clear that Apple is a consumer-and-hardware-focused company. At this point, you may be asking yourself “Where is all of this going?” The answer to that lies in Microsoft’s shift in company focus. They are becoming more consumer focused, but what exactly does that mean? The biggest change (at least that’s been in the news lately) is the pending purchase of Nokia’s handset division. This, in combination with their Surface line of tablets and the Xbox, will put Microsoft squarely in the realm of a hardware-focused company in addition to being a software-focused company. That can (and most likely will) shift the revenue split to looking at revenue based on software sales (both consumer and enterprise) and also hardware sales (mostly on the consumer side). If we look at things strictly from a Windows perspective, Microsoft clearly has a lot of irons in the fire at the moment. Discounting the various product SKUs available and painting the picture with broader strokes, there are currently 5 different Windows-based operating systems: Windows Phone Windows Phone 7.x, which runs on top of the Windows CE kernel Windows Phone 8.x+, which runs on top of the Windows 8 kernel Windows RT The ARM-based version of Windows 8, which runs on top of the Windows 8 kernel Windows (Pro) The Intel-based version of Windows 8, which runs on top of the Windows 8 kernel Xbox The Xbox 360, which runs it’s own proprietary OS. The Xbox One, which runs it’s own proprietary OS, a version of Windows running on top of the Windows 8 kernel and a proprietary “manager” OS which manages the other two. Over time, Windows Phone 7.x devices will fade so that really leaves 4 different versions. Looking at Windows RT and Windows Phone 8.x paints an interesting story. Right now, all mobile phone devices run on some sort of ARM chip and that doesn’t look like it will change any time soon. That means Microsoft has two different Windows based operating systems for the ARM platform. Long term, it doesn’t make sense for Microsoft to continue supporting that arrangement. I have long suspected (since the Surface was first announced) that Microsoft will unify these two variants of Windows and recent speculation from some of the leading Microsoft watchers lends credence to this suspicion. It is rumored that upcoming Windows Phone releases will include support for larger screen sizes, relax the requirement to have a hardware-based back button and will continue to improve API parity between Windows Phone and Windows RT. At the same time, Windows RT will include support for smaller screen sizes. Since both of these operating systems are based on the same core Windows kernel, it makes sense (both from a financial and development resource perspective) for Microsoft to unify them. The user interfaces are already very similar. So similar in fact, that visually it’s difficult to tell them apart. To illustrate this, here are two screen captures: Other than a few variations (the Bing News app, the picture shown in the Pictures tile and the spacing between the tiles) these are identical. The one on the left is from my Windows 8.1 laptop (which looks the same as on my Surface RT) and the one on the right is from my Windows Phone 8 Lumia 925. This pretty clearly shows that from a consumer perspective, there really is no practical difference between how these two operating systems look and how you interact with them. For the consumer, your entertainment device (Xbox One), phone (Windows Phone) and mobile computing device (Surface [or some other vendors tablet], laptop, netbook or ultrabook) and your desktop computing device (desktop) will all look and feel the same. While many people will denounce this consistency of user experience, I think this will be a good thing in the long term, especially for the upcoming generations. For example, my 5-year old son knows how to use my tablet, phone and Xbox because they all feature nearly identical user experiences. When Windows 8 was released, Microsoft allowed a Windows Store app to be purchased once and installed on as many as 5 devices. With Windows 8.1, this limit has been increased to over 50. Why is that important? If you consider that your phone, computing devices, and entertainment device will be running the same operating system (with minor differences related to physical hardware chipset), that means that I could potentially purchase my sons favorite Angry Birds game once and be able to install it on all of the devices I own. (And for those of you wondering, it’s only 7 [at the moment].) From an app developer perspective, the story becomes even more compelling. Right now there are differences between the different operating systems, but those differences are shrinking. The user interface technology for both is XAML but there are different controls available and different user experience concepts. Some of the APIs available are the same while some are not. You can’t develop a Windows Phone app that can also run on Windows (either Windows Pro or RT). With each release of Windows Phone and Windows RT, those difference become smaller and smaller. Add to this mix the Xbox One, which will also feature a Windows-based operating system and the same “modern” (tile-based) user interface and the visible distinctions between the operating systems will become even smaller. Unifying the operating systems means one set of APIs and one code base to maintain for an app that can run on multiple devices. One code base means it’s easier to add features and fix bugs and that those changes become available on all devices at the same time. It also means a single app store, which will increase the discoverability and reach of your app and consolidate revenue and app profile management. Now, the choice of what devices an app is available on becomes a simple checkbox decision rather than a technical limitation. Ultimately, this means more apps available to consumers, which is always good for the app ecosystem. Is all of this just rumor, speculation and conjecture? Of course, but it’s not unfounded. As I mentioned earlier, some of the prominent Microsoft watchers are also reporting similar rumors. However, Microsoft itself has even hinted at this future with their recent organizational changes and by telling developers “if you want to develop for Xbox One, start developing for Windows 8 now.” I think this pretty clearly paints the following picture: Microsoft is committed to the “modern” user interface paradigm. Microsoft is changing their release cadence (for all products, not just operating systems) to be faster and more modular. Microsoft is going to continue to unify their OS platforms both from a consumer perspective and a developer perspective. While this direction will certainly concern some people it will excite many others. Microsoft’s biggest failing has always been following through with a strong and sustained marketing strategy that presents a consistent view point and highlights what this unified and connected experience looks like and how it benefits consumers and enterprises. We’ve started to see some of this over the last few years, but it needs to continue and become more aggressive and consistent. In the long run, I think Microsoft will be able to pull all of these technologies and devices together into one seamless ecosystem. It isn’t going to happen overnight, but my prediction is that we will be there by the end of 2016. As both a consumer and a developer, I, for one, am excited about the future of Microsoft.

  • How to know which block device maps to which physical drive

    - by Karolis T.
    I have a server with software RAID 1, two hot-swap sata disks. One hard drive started showing errors, I'm thinking about removing and replacing it, only problem is that I have no idea which of the two correspond to which devices. And I can't shut the server down to find out. I have /dev/sda and /dev/sdb, /dev/sda is the failing one. Thought about doing something along the lines # mdadm --manage /dev/md0 --remove /dev/sda1 then somehow stop/suspend the drive using tuning software and try to listen which of the two stopped, but that's not gonna work in a noisy server environment. Drive panels have no LEDs. Thanks for any ideas!

  • Problem with Mono and .exe file

    - by Vere Nicolson
    I have purchased a piece of software to configure programable radio control transmitters. It says it will run on Linux, see below: Digital Radio runs on: Microsoft Windows 2000/2003/XP Microsoft Windows Vista/Seven/2008, Linux Ubuntu or a distribution with Mono, 32 or 64 bit, also in a virtual machine. Linux requires the Mono package installed, with also the Visual Basic 2005 runtime library. The Linux version is the same executable file of the Windows platform, and can be execute using Mono. You don't need Wine. All the tests have been done on Ubuntu Desktop 10.10 I have tried for weeks to get the drivers for the cable to work in XP or Win7 and I admit defeat. It looks like Ubuntu can run the cable effortlessly but now I can't get the software going. Tried to run in Ubuntu 10.04 with mono, GUI failed and I got the following message in terminal. $ mono ~/Desktop/GigRadioLinux/DigitalRadio/DigitalRadio.exe The entry point method could not be loaded Windows installation requires using a 30 odd character Passkey and a 4.24k text file as a "license" to be entered during running of the exe file. Can someone tell me how I enter the passkey and license into terminal, or is that not my primary problem? I don't understand "entry point method". Tried Wine and that didn't work either. The developer responded to my earlier emails re the cable drivers, but hasn't replied to questions regarding this. If I have left out anything important let me know and I will try to supply more information.

  • Create a Search Filter List in Google Chrome

    - by Asian Angel
    Are you tired of unwanted and/or non-relevant results cluttering up the search results at Bing, Yahoo, and Google? With the Search Filter extension for Chrome you can easily remove the unwanted “chaff” from your search results. Note: The extension only works on Bing, Yahoo, and Google at this time. Before For our example we conducted a search for “anime wallpapers” at Yahoo Singapore, Bing Singapore, and Google. In each set of results we decided to focus on results that would display either a yellow or red warning color from WOT. You can see our targeted result for Yahoo Singapore… The one for Bing Singapore… And the targeted result from Google. Search Filter in Action As soon as you install the extension you should take a quick look at the “Options”. At first the “Filters List Area” will be empty but will not remain so for long as you create your own filter list. The second part may or may not be of interest to you…the ability to opt into the filter service. If you opt in your filter list will be connected to your “Google Account” and will be available on any of your Chrome installs with the extension installed (and set to “Opt In”). Keep in mind that if you choose this option the filter list that you create will be aggregated anonymously and have a GUID number attached to it. After installing the extension we refreshed each of our three search pages…notice the small red circle button beside each search result link. Clicking on the red circle button will cause the entire browser window area to “shade out” temporarily while you decide between adding that website to the filter list or cancelling the action. If you add a website to the filter list that result will immediately disappear from the search results list without refreshing the webpage. Looks like we have another website at the bottom that we could add to the filter list… Click, click, click! After adding one website from each of the three search services you can see that our filter list has gotten off to a nice start. If for some reason you accidentally add a website to the list or change your mind about a website simply click on the red circle button to remove that particular listing. Conclusion If you are looking for an easy way to create a search filter list then this is definitely an extension that is worth taking the time to look at.
