• Linking "Wave Volume" to "Main Speaker Volume"

  - by ZorbaTHut

  I've got a Logitech keyboard and a digital sound device. The Logitech keyboard has a little volume wheel that sets the Main Speaker Volume. The digital sound device ignores the Main Speaker Volume and only pays attention to Wave Volume. See the issue? I'm looking for a program that can link Wave Volume to Main Speaker Volume. The closest I've found is a little utility named VolumeTracker, but it eats an entire CPU core, which is a bit much for a program of this functionality. Alternatively, I'd take a way to make the standard Logitech drivers change Wave Volume instead of Main Speaker Volume.

• Setting up Samba shares on a Linux VPS

  - by 101265052760541259879

  Hi, I'm trying to set up a folder that can be accessed via Windows clients over the net on my Linux VPS on which our companies website resides. I know a little bit about Linux, and have used Samba before to browse Windows shares from a Linux laptop. I'm guessing it's possible to do the reverse - to share a folder from Linux TO a Windows client. I have root SSH access to the VPS, would anyknow know what steps I need to take to set up the share, and how I can secure it, ideally with a simple username/password so the Windows clients can connect easily? Many thanks, Jack

• IIS requesting certificates even though set to ignore

  - by lupefiasco

  I have a web site in IIS 6 with directory security set to Require secure channel (SSL) and Require 128-bit encryption. Also, the Client certificates setting is set to "Ignore client certificates". When I hit https://servername/resource in Internet Explorer and Chrome , I am prompted for a certificate. I can cancel the prompt, and the resource will load, but I don't want to see this prompt at all. I looked at the virtual directories and resources within the web site, and they all have the ignore client certificates setting on. Could there be another setting, perhaps in the metbase, that is overriding the web site's directory security settings?

• PHP Browser Game Question - Pretty General Language Suitability and Approach Question

  - by JimBadger

  I'm developing a browser game, using PHP, but I'm unsure if the way I'm going about doing it is to be encouraged anymore. It's basically one of those MMOs where you level up various buildings and what have you, but, you then commit some abstract fighting entity that the game gives you, to an automated battle with another player (producing a textual, but hopefully amusing and varied combat report). Basically, as soon as two players agree to fight, PHP functions on the "fight.php" page run queries against a huge MySQL database, looking up all sorts of complicated fight moves and outcomes. There are about three hundred thousand combinations of combat stance, attack, move and defensive stances, so obviously this is quite a resource hungry process, and, on the super cheapo hosted server I'm using for development, it rapidly runs out of memory. The PHP script for the fight logic currently has about a thousand lines of code in it, and I'd say it's about half-finished as I try to add a bit of AI into the fight script. Is there a better way to do something this massive than simply having some functions in a PHP file calling the MySQL Database? I taught myself a modicum of PHP a while ago, and most of the stuff I read online (ages ago) about similar games was all PHP-based. but a) am I right to be using PHP at all, and b) am I missing some clever way of doing things that will somehow reduce server resource requirements? I'd consider non PHP alternatives but, if PHP is suitable, I'd rather stick to that, so there's no overhead of learning something new. I think I'd bite that bullet if it's the best option for a better game, though.

• Out of memory Problem

  - by Sunil

  I'm running a C++ program in Ubuntu 10.04 (32-bit system architecture). If I calculate the amount of memory that my program uses, it comes up to 800MB. I have a 4GB RAM in place. But still before the program even finishes it throws an out of memory exception. Why is that happening ? Is it because of the structure of the memory or implementation problems or what could possibly trigger this issue ? I've had seen this problem quite a number of times before but never understood the reason behind it. Have any of you handled this case before ?

• Is “Application Programming Interface” a bad name?

  - by Taylor Hawkes

  Application programming interface seems like a bad name for what it is. Is there a reason it was named such? I understand that people used to call them Advanced Programming Interfaces and then renamed to Application Programming Interface. Is that why it is poorly named? Why is it not named Application (to) Programmer Interface. I guess I'm just confused of the meaning behind that name? I write more about my confusion around the name here: BREAKING DOWN THE WORD “APPLICATION PROGRAMMING INTERFACE” This is a very confusing word. We mostly understand what the word Interface means, but “Application Programming”, what even is that. Honestly I'm confused. Is that suppose to be two words like “Application”, “Programming” and then the “Interface” is suppose to mean between the two? Like would a “Computer Human Interface” be an interface between a “Computer” and a “Human” (monitor , keyboard, mouse ) or is a “Computer Human” a real thing - perhaps the terminator. So a CHI is our boy Kyle Reese who is the only way we are able to work with the computer human. I think more likely “Application Programming Interface” was simply poorly named and doesn't really make sense. It was originally called an “Advanced Programming Interface” , but perhaps being a bit to ostentatious merged into the now wildly accepted “Application Programming Interface”. So now, not wanting to change an acronym has confused the living heck out everyone.... Any thoughts or clarification would be great, I'm giving a lecture on this topic in a month, so I would prefer not to BS my way through it.

• Correct way to drive Main Loop in Cocoa

  - by Kyle

  I'm writing a game that currently runs in both Windows and Mac OS X. My main game loop looks like this: while(running) { ProcessOSMessages(); // Using Peek/Translate message in Win32 // and nextEventMatchingMask in Cocoa GameUpdate(); GameRender(); } Thats obviously simplified a bit, but thats the gist of it. In Windows where I have full control over the application, it works great. Unfortunately Apple has their own way of doing things in Cocoa apps. When I first tried to implement my main loop in Cocoa, I couldn't figure out where to put it so I created my own NSApplication per this post. I threw my GameFrame() right in my run function and everything worked correctly. However, I don't feel like its the "right" way to do it. I would like to play nicely within Apple's ecosystem rather than trying to hack a solution that works. This article from apple describes the old way to do it, with an NSTimer, and the "new" way to do it using CVDisplayLink. I've hooked up the CVDisplayLink version, but it just feels....odd. I don't like the idea of my game being driven by the display rather than the other way around. Are my only two options to use a CVDisplayLink or overwrite my own NSApplication? Neither one of those solutions feels quite right.

• How do I restore a non-system hard drive using Time Machine under OSX?

  - by richardtallent

  I dropped one of the external drives on my Mac Pro and it started making noises... so I bought a replacement drive. No biggie, that's why I have Time Machine, right? So now that I have the new drive up and initialized, how do I actually restore the drive from backup? Time Machine is intuitive when it comes to restoring the system drive or restoring individual folders/files on the same literal device, but I'm a bit stuck in how to properly restore an entire drive that is not the boot drive. I saw one suggestion to use the same volume name as the old drive and then go into Time Machine. Haven't tried that since the information is unconfirmed. For now, I just went to the Time Machine volume, found the latest backup folder for that volume, and I'm copying the files via Finder. Of couse, I expect this to work just fine, but I feel like I'm missing something if that's the "proper" way to do this.

• Windows 7 using exactly HALF the installed memory

  - by Nathan Ridley

  I've taken this directly from system information: Installed Physical Memory (RAM) 4.00 GB Total Physical Memory 2.00 GB Available Physical Memory 434 MB Total Virtual Memory 5.10 GB Available Virtual Memory 1.19 GB Page File Space 3.11 GB Also the BIOS reports a full 4GB available. Note the 4gb installed, yet 2gb total. I understand that on a 32 bit operating system, you'll never get the full 4gb of ram, however typically you'll get in the range of 2.5-3.2gb of ram. I have only 2gb available! My swap file goes nuts when I do anything! Note that I have dual SLI nvidia video cards, each with 512mb of on board ram, though I have the SLI feature turned off. Anybody know why Windows might claim that I have exactly 2gb of ram total? Note: previously asked on SuperUser, but closed as "belongs on superuser" before this site opened: http://serverfault.com/questions/39603/windows-7-using-exactly-half-the-installed-memory (I still need an answer!)

• Venezuela's Highly Inflationary Economy Means Changes to Financial Statements

  - by Theresa Hickman

  This is a bit of an esoteric topic, but given the number of U.S. Companies (particularly oil companies) that operate and have subsidiaries in Venezuela, I think it is worthy of an honorable mention. As you may or may not know, Venezuela's currency has had some changes over the years. In 2008, the Venezuelan Bolivar became the Bolivar Fuerte which dropped three zeros. So Bs.10,000 became Bs.F.10 and all their bills and coins were changed to reflect this. Then on Jan. 8, 2010, the government devalued the currency by 100%. The conversion from VEF to USD dropped from 2.15 to 4.30. (I always wanted to visit Venezuela; I guess it's time to book my vacation). The SEC recently labeled Venezuela a highly inflationary economy. This means that US companies with investments/subsidiaries in Venezuela will need to apply highly inflationary accounting rules starting on Jan. 1, 2010. In addition, companies need to make more detailed disclosures when the Venezuelan reported balances differ from the actual US dollar denominated balances. In a nut shell, if you formerly used translation, then starting Jan 1 of this year, you must now use remeasurement (or temporal method) to restate your Venezuelan entity's financial statements. See ASC topic 830, Foreign Currency Matters, which states that "[t]he financial statements of a foreign entity in a highly inflationary economy shall be remeasured as if the functional currency were the reporting currency." For you non-accountants that I haven't bored and are still reading at this point, the reason why the SEC is doing this is to ensure financial statements are presented as accurately as possible. Hyperinflationary economies have volatile currencies, such as Venezuela (it's not every day a currency devalues 100% overnight) which can distort financial statements if the local currency (Venezuelan Bolivar Fuerte) is used as the functional currency. To make financial statements more accurate, the reporting currency of the U.S. parent (US dollars) should be used as the functional currency. FASB.orgactually has a nice write-up on this.

• Looking for zsh completion file for osX native commands

  - by Chiggsy

  I've been digging deep into what actually comes with osX in /usr/bin and especially /usr/libexec. Quite good stuff really, although the command syntax is a bit.. odd. Let me direct the curious to the command that made me think of this: networksetup -printcommands I can not think of a command that better illustrates the need for good completion. security -h perhaps, but those commands have a familiar easy-to-read format. I beseech the community, please point me to a place where I can find such a thing. I never type them right, and I ache for tab completion for this Anyone have any idea where I could grab something? I'd prefer to stand on the shoulders of giants instead of trying to make a zsh/bash completion script leap into the world, ready for battle, like Athena, from my forehead. I am no Zeus when it comes to compctl. Not at all.

• Domain DNS Lookup time

  - by Maxim Dsouza

  I have a website hosted at www.doondoo.com. The site when loaded in the browser for the first time, takes a bit of time to load. It looks like the DNS lookup takes a lot of time. Once the site is loaded on the browser, other pages load very quickly. The application is hosted on Linode and I have pointed my domain to the nameservers of Linode i.e ns1.linode.com and ns2.linode.com I wanted to know what is the reason behind this delay in the loading. And what could be the possible means to improve it. Thanks in advance.

• Feed Reader's - Looking for some suggestions

  - by bryan_ruiz

  I am doing my best to make it a point to keep an eye on some blogs of people in my industry, and am looking for a good feed reader. I use chrome. I live in chrome, and if I am not in Chrome, I am using xterm. Yet, I do get my tweets in Pidgin and do all my talking discussion from that. Maybe it makes sense to integrate something in that? I see web feed readers as a bit too distant to make good use of it (eg, have to open a page, and less 'in your face'). Although, I am a big fan of google stuff and use google apps and google voice and google cals and google docs, etc.. So how is feedburner? I like to preserver time. It'd be interesting if I could read my feeds offline on my laptop or ChromeOS CR-48 with offline websites? Well, would love to hear what you guys are doing and suggest.

• How do I get my laptop's screen brightness settings back?

  - by Mason Wheeler

  From when I bought it up until yesterday, my laptop would dim the screen automatically if you let it sit for long enough, and then if you hit a key or moved the mouse, the brightness would jump back to what you had it at. I enjoy that behavior. It works well. Then I booted it up today, and found that now it will dim the screen automatically if you let it sit for long enough, but it doesn't restore the screen brightness. I have to do that manually, every single time, and it's getting really old really fast. It's an Alienware M17 running Windows 7 64-bit, in case that helps.

• Homepage 301 Redirect to SSL Homepage

  - by user33692

  I'm hoping somebody might be able to provide a bit of advice on an issue I am having. I have 1 site where we implemented a 301 redirect on the homepage from http to https. We have links on the homepage to other parts of the site that are not under SSL (in fact there is only one other page under SSL). When I go to our webmaster account I notice that we are not being provided with any webmaster information (search queries, backlinks) related to our homepage under SSL. I performed a Fetch Google on the homepage and the information it returned is: HTTP/1.1 301 Moved Permanently Date: Fri, 08 Nov 2013 17:26:24 GMT Server: Apache/2.2.16 (Debian) Location: https://mysite.com/ Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 242 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://mysite.com/">here</a>.</p> <hr> <address>Apache/2.2.16 (Debian) Server at mysite.com</address> </body></html> I am worried that the fact that Google Fetch is not getting the correct Title Tags and Meta information from our homepage and that this is hurting our search results. Additionally, I am worried that we need to do something specific with the SiteMap to ensure that Google is correctly indexing all our pages and being able to flow from the https to the http without issues. Does anybody have any advice on how we can correctly set this up or be sure that Google is fetching the correct information?

• List SQL Server Instances using the Registry

  - by BuckWoody

  I read this interesting article on using PowerShell and the registry, and thought I would modify his information a bit to list the SQL Server Instances on a box. The interesting thing about listing instances this was is that you can touch remote machines, find the instances when they are off and so on. Anyway, here’s the scriptlet I used to find the Instances on my system: $MachineName = '.' $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $MachineName) $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" ) $regkey.GetValueNames() You can read more of his article to find out the reason for the remote registry call and so forth – there are also security implications here for being able to read the registry. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems.

• Installazione ATI Mobility Radeon HD 5650 su Ubuntu 11.10

  - by Antonio

  Salve a tutti, possiedo un portatile HP Pavillion dv6 3110 con scheda video dedicata ATI Mobility Radeon HD 5650 da 1 Giga ed ho installato da poco Ubuntu 11.10 Versione 64 bit. Ho seguito molte guide su internet per installare i driver per la mia scheda video ma nessuna ha dato esito positivo. Nella finestra "driver aggiuntivi" sono riuscito ad installare i "Driver grafici fglrx proprietari ATI/AMD" ma dopo il riavvio non riesco ad utilizzare correttamente la scheda video. Mentre i "Driver grafici fglrx proprietari ATI/AMD (aggiornamenti post-release)" non me li fa proprio installare segnalando un errore che riporto di seguito "L'installazione di questo driver non è riuscita.Consultare i file di registro per maggiori informazioni: /var/log/jockey.log". Ho pensato allora di scaricare direttamente dal sito di AMD gli ultimi driver rilasciati attraverso il pacchetto "amd-driver-installer-12-3-x86.x86_64.run", l'ho lanciato, ho seguito il wizard di installazione, l'installazione viene completata, digito "sudo aticonfig --initial" per la configurazione iniziale, ma al riavvio del pc appaiono soltanto scritte su schermo nero con una serie di "OK" e qualche "FAIL". Ho provato questa procedura anche per le versioni precedenti dei driver, ma il risultato è sempre lo stesso. Sono disperato. Riuscirò mai ad utilizzare la mia scheda video? Vi incollo per completezza ciò che mi appare all'esecuzione del comando "lspci -nn | grep VGA" per visualizzare i processori grafici presenti sul mio pc: 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Madison [AMD Radeon HD 5000M Series] [1002:68c1] Grazie anticipatamente a coloro che potranno aiutarmi. Cordiali Saluti Antonio Giordano

• Email setup on dedicated servers

  - by zaf

  Am thinking seriously of renting a dedicated server. Now I know how to setup apache and the underlying scripting engines and databases but I'm a bit clueless with how the emails would work. Currently, I'm on a shared hosting account and I get a fancy gui which allows me to nicely add a domain, setup nameservers and then the emails for all domain names with either simple forwarding or the full account which also has a webmail app behind it. What options do I have? Are there non complicated ways to have the same email setup experience? Or are there reliable external providers I could use? My past experiences with sendmail/postfix have always been fuzzy - not exactly knowing whats happening behind the scenes.

• Scene Graph for Deferred Rendering Engine

  - by Roy T.

  As a learning exercise I've written a deferred rendering engine. Now I'd like to add a scene graph to this engine but I'm a bit puzzled how to do this. On a normal (forward rendering engine) I would just add all items (All implementing IDrawable and IUpdateAble) to my scene graph, than travel the scene-graph breadth first and call Draw() everywhere. However in a deferred rendering engine I have to separate draw calls. First I have to draw the geometry, then the shadow casters and then the lights (all to different render targets), before I combine them all. So in this case I can't just travel over the scene graph and just call draw. The way I see it I either have to travel over the entire scene graph 3 times, checking what kind of object it is that has to be drawn, or I have to create 3 separate scene graphs that are somehow connected to each other. Both of these seem poor solutions, I'd like to handle scene objects more transparent. One other solution I've thought of was traveling trough the scene graph as normal and adding items to 3 separate lists, separating geometry, shadow casters and lights, and then iterating these lists to draw the correct stuff, is this better, and is it wise to repopulate 3 lists every frame?

• Two tor clients

  - by Intellektus

  I have been experimenting with the thought of running two Tor clients at once on my machine. So I decided to try it and modified the source a bit to let me run two clients at once (of course with separate data dirs). But they both get the same exit node, and if I try to switch exit node on one of them via its control port, they both get switched. I have been experimenting with this some more, and Tor always seem to get the same IP, even if I run several separate clients (on the same machine) at once. Is this the expected behavior?

• What are some hosted MySQL solutions?

  - by bigmac

  I would like to host a MySQL database somewhere. The basic solution would be to get a VPS, but then I am stuck doing all the sysadmin stuff. It's not terribly difficult if you are not doing anything fancy, but if something goes wrong (like a security breach), it may be hard to resolve or even diagnose in the first place. On the other end of the spectrum, I found Xeround and Amazon RDS. Xeround is not exactly standard MySQL. Amazon seems a bit complex to get started (which is weird because they specifically say it is "simple to deploy"). Why is there nothing in the middle? Is there no demand for a basic hosted MySQL solution?

• How to get better video quality in Lync?

  - by sinned

  I want to use a ConferenceCam from Logitech to stream talks live via Lync. When I view the RAW webcam image via VLC, the quality is very good (but the latency is high because of buffering). However, when I stream it using Lync, the video gets blurry. Is there a way to ensure QoS in Lync or otherwise improve the video quality to (near-)native? I would rather have some dropped frames than a lower resolution where I can't read the slides. In my setup, I use Lync with an Office365-E3 contract, so I have no Lync-Server in my network. I thought about replacing Lync completely with VLC, but I first want to try Lync because VLC will probably cause firewall issues. Also, I haven't looked up the VLC parameters for less buffering, faster encoding, a bit lower resolution (natively it's more than HD) and streaming.
