  • Are there too many qualified software development engineers chasing too few jobs?

    - by T Gregory
    I am trying to write this question in a non-argumentative way, but it is quite emotionally charged for some, so please bear with me. In the U.S., we hear constantly from CEOs that they cannot find enough qualified software engineers. In fact, it is the position of the U.S. government that demand for software engineering talent outpaces supply. This position can be clearly seen in the granting of tens of thousands of H1B visas, but also in the following excerpt from the official 2010-11 Bureau of Labor Statistics Occupational Outlook Handbook: Employment of computer software engineers is expected to increase by 32 percent from 2008-2018, which is much faster than the average for all occupations. In addition, this occupation will see a large number of new jobs, with more than 295,000 created between 2008 and 2018. Demand for computer software engineers will increase as computer networking continues to grow. For example, expanding Internet technologies have spurred demand for computer software engineers who can develop Internet, intranet, and World Wide Web applications. Likewise, electronic data-processing systems in business, telecommunications, healthcare, government, and other settings continue to become more sophisticated and complex. Implementing, safeguarding, and updating computer systems and resolving problems will fuel the demand for growing numbers of systems software engineers. New growth areas will also continue to arise from rapidly evolving technologies. The increasing uses of the Internet, the proliferation of Web sites, and mobile technology such as the wireless Internet have created a demand for a wide variety of new products. As more software is offered over the Internet, and as businesses demand customized software to meet their specific needs, applications and systems software engineers will be needed in greater numbers. In addition, the growing use of handheld computers will create demand for new mobile applications and software systems. As these devices become a larger part of the business environment, it will be necessary to integrate current computer systems with this new, more mobile technology. However, from the the employee side of the equation, we often hear the opposite. Many of the stories of SDEs with graduate degrees and decades of experience on the unemployment line, or the big tech interview war stories, are anecdotal, for sure. But, there is one piece of data that is neither anecdotal nor transitory, and that is the aggregate decisions of millions of undergraduates of what degree to pursue. Here, a different picture emerges from the data, and that picture is not good for the software profession. According the most recent Taulbee Survey from Computer Research Association, undergrad degree production in CS and CE has fallen nearly 60% since 2004. (Undergrad enrollments have ticked up in the past two years, but only modestly). Here we see that a basic disconnect between what corporate CEOs and the US government are saying and what potential employees really think about job prospects in software engineering. So my questions are these. Who are we to believe? Is there an acute talent shortage, or is there a long-term structural oversupply in the SDE labor market? Can anyone provide reliable data on long-term unemployment among SDEs? How many are leaving the profession due to lack of work? Real data is most helpful. Thanks.

  • How should I replan A*?

    - by Gregory Weir
    I've got a pathfinding boss enemy that seeks the player using the A* algorithm. It's a pretty complex environment, and I'm doing it in Flash, so the search can get a bit slow when it's searching over long distances. If the player was stationary, I could just search once, but at the moment I'm searching every frame. This takes long enough that my framerate is suffering. What's the usual solution to this? Is there a way to "replan" A* without redoing the entire search? Should I just search a little less often (every half-second or second) and accept that there will be a little inaccuracy in the path?

  • Why is permadeath essential to a roguelike design?

    - by Gregory Weir
    Roguelikes and roguelike-likes (Spelunky, The Binding of Isaac) tend to share a number of game design elements: Procedurally generated worlds Character growth by way of new abilities and powers Permanent death I can understand why starting with permadeath as a premise would lead you to the other ideas: if you're going to be starting over a lot, you'll want variety in your experiences. But why do the first two elements imply a permadeath approach?

  • Global vs. Local Monthly Searches in Adwords keyword tool

    - by Gregory
    I'm trying to learn how to use a keyword tool in Adwords. Here's what I entered: Country- Russia Language-Russian Desktop and laptop devices And the keyword was ???? ? ??????? (tours to Israel in Russian Cyrillic letters) . As a broad match type... Now... the results that I got were: Global monthly: 60,500 Local monthly: 40,500 If I got it right..."Global monthly" means in this context : worldwide average monthly searches for this search term in ANY language in any Google search site (google.ru, google.com.ua, google.com, google.fr etc.). It's all nice, BUT... Then I made an query for tours to Israel in English in the US...And I got: Global monthly: 60,500 Local monthly: 27,100 That doesn't make any sense to me though! How come the total sum (the global) is actually a smaller number than a combined sum of just TWO countries??? (27,100+40,500=67,60060,500) By "any language" they mean a translation of the term into ANY possible language???Or maybe by "language" Google means the language of searchers' operating system? or their browsers' language?

  • Configuring mouse buttons to switch between apps?

    - by Matt Gregory
    I just installed 14.04, so I'm using the default setup (Unity, I guess). I have these two extra mouse buttons on the side of my mouse. Is there any way to map these so they can switch between open apps? What would be perfect is if clicking on button 6 (or whatever it is) would cycle forward through apps, button 7 would go backwards, and holding one of the buttons would show the task list and let you click on the app you want. That's really what I want.

Is anyone aware of anything different with Yahoo! that would stop these from signing? TIA

  • XP Mode in Windows 7 professional recently ceased to work

    - by Ian FLetcher
    I have used Windows XP Mode in Windows Professional 7 once a week for around 2 years to run Quicken 98. About 2 weeks ago the XP Mode completely stopped working. I get different responses when I try to launch. I can sometimes see a launch screen for XP (which I never used to get) which then hangs Sometimes I just get a black screen Sometimes I get an error message in a cmd like interface that says "windows could not start because the following file is missing or corrupt \system32\ntoskrnl.exe please reinstall a copy of the above file. I have noticed that in the tools tab at the top of the screen "enable integration features" is greyed out. Any recommendations? Ian

  • MASM Syntax Highlighting in C++ for Visual Studio 2010

    - by Ian Mallett
    So, I had Visual Studio 2010 Ultimate, and everything was great. However, I was confused, thought I wanted MASM, and installed the SDK. This causes strange problems for syntax highlighting. When I'm editing a C/C++ file, for instance, a lot of words (e.g., "data", "add", "sub", "mul", "div", "eax", etc.) are highlighted. At first, I thought I'd just learn to live with it, but it has gotten annoying. I could find nothing online, so, I deleted the MASM folder completely (method of uninstallation), uninstalled Visual Studio, and then installed it again. I firedit up, and the problem persists. Any clues? Thanks, Ian

  • Problem with GetDefaultPrinter() over a VPN c++

    - by Ian Crowder
    I am writing an application that gets its dimensions from the paper ratio of the default printer of the local computer. This all works well unless the default printer is over a VPN. When this is the case, calling GetDefaultPrinter() takes too long. I need to find a way to put a time constraint on GetDefaultPrinter() and if it exceeds that constraint, break out of the function. Any possible solutions would be great. Thanks, Ian

  • Browser Client Side Storage aka a large Cookie

    - by Ian
    Hi, I need to store about 20-30k or data on the client side when using a website. I was using a cookie, but this is to small for my needs. Is there something else that I can use? I need to be able to do this via javascript. Server side storage is a last resort but not what I am looking for. I need it to work for Chrome, IE and firefox. Thanks Ian

  • Whats the difference between local and remote addresses in 2008 firewall address

    - by Ian
    In the firewall advanced security manager/Inbound rules/rule property/scope tab you have two sections to specify local ip addresses and remote ip addresses. What makes an address qualify as a local or remote address and what difference does it make? This question is pretty obvious with a normal setup, but now that I'm setting up a remote virtualized server I'm not quite sure. What I've got is a physical host with two interfaces. The physical host uses interface 1 with a public IP. The virtualized machine is connected interface 2 with a public ip. I have a virtual subnet between the two - 192.168.123.0 When editing the firewall rule, if I place 192.168.123.0/24 in the local ip address area or remote ip address area what does windows do differently? Does it do anything differently? The reason I ask this is that I'm having problems getting the domain communication working between the two with the firewall active. I have plenty of experience with firewalls so I know what I want to do, but the logic of what is going on here escapes me and these rules are tedious to have to edit one by one. Ian

  • How does the EFI partition work and can I boot an x86 OS with a bootx64.efi file?

    - by Ian
    I have a Thinkpad X230 laptop and I want to install Linux Mint Debian Edition along side Windows 7 on my GPT formatted SSD with the BIOS in UEFI mode. The problem is that I don't understand how EFI booting works. There seems to be an EFI partition involved with some folders and binary files in it. GRUB 2 seems to be able to make more folders in it (I followed this guide http://www.thinkwiki.org/wiki/UEFI_Firmware), but it appears that the only file that does anything is the bootx64.efi file in the /efi/boot folder of the EFI partition (I am not sure if this is always the case, but it appears to be the case for my laptop http://www.thinkwiki.org/wiki/Category:X220). Here is what I have been able to do: I can install Linux Mint Debian Edition x86 with the BIOS in BIOS mode on my SSD. I can then install grub-efi and follow the guide linked above. The problem is that I don't get a GRUB prompt when I switch the BIOS to UEFI mode. It just boots Windows. It appears that I can either boot from the SSD or something called "Windows Boot Manager". If I replace the bootx64.efi with the file created by GRUB, I can no longer boot directly from the SSD. Booting from "Windows Boot Manager" still works fine. I realize that the guide says to use x64 Linux, but Linux Mint Debian Edition x64 hangs during the install process. I am really confused. What should I do? Can anyone explain how the EFI boot partition works? Can a bootx64.efi boot an x86 OS? Should I just give up with using UEFI? I haven't been able to find very much useful information about using Debian based operating systems with UEFI. Thanks, Ian

  • Win 2008 R2 terminal server and redirected printer queue security

    - by Ian
    I have a case where I need a non-priv account to be able to make a modification to the redirected printer. I know, its not advisable but we're not giving them access - changes will be made in code. So, following the docs (http://technet.microsoft.com/en-us/library/ee524015(WS.10).aspx) I modified the default security for new printer queues. This doesnt work though as windows doesn't seem to assign the privs you configure in the printer admin tool to redirected printer queues. As I test I added a non-priv test user to the default security tab in the printer admin tool (control panel - admin tools - printer admin. I assigned it all privs (its a test) and logged the user into the terminal server. The redirected printers duely appeared as usual. However if I open the printer properties - security tab, the user appears in the list of accounts/groups but the options I selected (all privs) are not set. Instead the user special privs box is marked and when I click on 'advanced options' and view them, there is nothing marked. So, something is clearing these options.... the question is, why and how can I convince it not to? Ian

  • Active FTP client blocked on Windows XP

    - by Ian Hannah
    Summary We have a FTP server (running in active mode). We have an FTP client which is connecting to the server, carrying out a task and then closing the connection. The FTP Client can perform this operation on multiple threads. Problem We have a situation where customers are experiencing occasional failures to carry out operations on a FTP connection. The actual connection has been made to the server but when the server attempts to return data on the data port if fails. Observations We have a simple test FTP client which is running two separate threads. Each thread is performing a recursive listing of files from a root directory. With the firewall running on the client machine the hang happens within a few minutes. If the firewall is turned off on the client machine, the test application seems to run correctly. This does point to a potential firewall issue. However, with the firewall on we can list files on our company FTP server without any issues. If the simple test FTP client runs a single thread then we do not experience any problems whether or not the firewall is turned on. We have another simple test FTP client which was running 4 threads (with each opening a new FTP connection, doing a directory listing and closing the FTP connection as fast as possible) overnight with the firewall turned off. With the firewall turned on it fails in a short space of time. The confusing thing is that if the test FTP client and the FTP server are run on the same machine the failure occurs even though the firewall is turned off. This means that the problem may not be firewall related. Any help with what this could be would be much appreciated. Thanks Ian

  • Why *do* windows print queues occasionally choke on a print job

    - by Ian
    Y'know they way windows print queues will occasionally stop working with a print job at the head of the queue which just won't print and which you can't delete? Anyone know whats going on when this happens? I've been seeing this since the NT4 days and it still happens on 2008. I'm talking about standard IP connected laser printers - nothing fancy. I support a lot of servers and loads of workstations and see this happen a few times a year. The user will call saying they can't print. When you examine the print queue, which in my case will generally be a server based queue shared out to the workstations, you find a print job which you cannot cancel. You also can't pause it, reinitialize it, nothing. Stopping the spooler is the usual trick and works sometimes. However I occasionally see cases which even this doesn't cure and which a reboot is the only solution. Pause the queue, reboot, when it comes back up the job can then be deleted. Once gone the printer happily goes back to its normal state. No action is ever necessary on the printer. I regard having to reboot as last resort and don't like it. What on earth can be going on when stopping the process (spooler) and restarting it doesn't clear a problem? Its not linked to any manufacturer either. I've seen this on HPs, lexmark, canon, ricoh, on lasers, on plotters.... can't say I ever saw this on dot matrix. Anyone got any ideas as to what may be going on. Ian

  • Can't ping localhost/or reach locally hosted domain

  • How to detect Javascript pop-up notifications in WatiN?

    - by Ian P
    I have a, what seems to be, rather common scenario I'm trying to work through. I have a site that accepts input through two different text fields. If the input is malformed or invalid, I receive a Javascript pop-up notification. I will not always receive one, but I should in the event of (like I said earlier) malformed data, or when a search result couldn't be found. How can I detect this in WatiN? A quick Google search produced results that show how to click through them, but I'm curious as to whether or not I can detect when I get one? In case anyone is wondering, I'm using WatiN to do some screen scraping for me, rather than integration testing :) Thanks in advance! Ian

    Does anyone know how to get the blur event to fire on the document for the iPhone? I'm trying to get it to fire either when a user changes windows in Safari, or when they open their bookmarks or when they decide to add the page to their homescreen. But none of these are firing it. Here's my code: $(document).blur( function () { document.title = "Ian Taylor"; }); I've tried "document", "window", "'body'". Nothing seems to work.

  • Python and Postgresql

    - by Ian
    Hi all, if you wanted to manipulate the data in a table in a postgresql database using some python (maybe running a little analysis on the result set using scipy) and then wanted to export that data back into another table in the same database, how would you go about the implementation? Is the only/best way to do this to simply run the query, have python store it in an array, manipulate the array in python and then run another sql statement to output to the database? I'm really just asking, is there a more efficient way to deal with the data? Thanks, Ian

  • How to create a BBC style (facebox?) help popup

    - by Ian Batten
    Hi guys, I have tried to take apart the code, but can't seem to replicate it. On the BBC weather homepage, http://news.bbc.co.uk/weather/, you will see a little help quetionmark in a circle in the top right corner or some of the boxes. When you click on it, it brings up a nice help popup, that looks a little like facebox. The main thing I like about this, is the little arrow that points back to the help button to the right of the container. Facebox is just a standard square. If anyone knows how to replicate this, some help would be greatly appreciated. Regards, Ian

  • Regex: Strip HTML attributes except SRC

    - by Ian Silber
    Hi, I'm trying to write a regular expression that will strip all tag attributes except for the SRC attribute. For example: <p id="paragraph" class="green">This is a paragraph with an image <img src="/path/to/image.jpg" width="50" height="75"/></p> Would be returned as: <p>This is a paragraph with an image <img src="/path/to/image.jpg" /></p> I have a regular expression to strip all attributes, but I'm trying to tweak it to leave in src. Here's what I have so far: <?php preg_replace('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i', '<$1>', '<html><goes><here>'); Using PHP's preg_replace() for this. Thanks! Ian
