• Spotlight on an office - Nairobi, Kenya

  - by Maria Sandu

  Hi everyone, my name is Joash Mitei. I am a graduate Intern at Oracle Systems Kenya and I will briefly take you through our offices and the working environment here in Nairobi, Kenya. I’ve been with Oracle since February 2012 and I’m responsible for Applications Pre-sales focusing on Oracle EPM and E-Business Suite. My background is Finance and Accounting therefore joining Oracle was almost a totally a different ball game but the transition has been smooth. The Oracle offices here are located on the second floor of Mebank Towers. We moved to the 2nd floor just three months ago from the 5th floor mainly because of the growing workforce. We are covering the whole Eastern Africa region hence diversity in culture is evident. This is a plus since you get to interact with people of very different backgrounds, cultures and ways of thinking. The building itself is on the outskirts of the CBD hence free from the hustle and bustle of the town. The office is split into different sections; there is a main working area which has an open desk design that fosters interaction between colleagues, there are 4 conference rooms for meetings and presentations, there are 3 quiet rooms for a little privacy when needed and there is a dining area for meals and ‘hanging out’. The working environment is world-class, to say the least. The employees are very professional, quite smart and needless to say, very busy. There are 4 interns covering sales and pre-sales in both Tech and Apps. As an intern you get support from your supervisor but you are required to show initiative yourself and thus the need to be very pro-active and inquisitive. The local management is well structured and communicative to ensure effectiveness and efficiency in the office. Apart from the daily work, we usually have events to boost staff morale such as ‘TGIF hang -out’, football matches against each other or versus other companies, and team building retreats. All these are monumental in fostering the RED POTENTIAL. We also do numerous CSR activities in the local communities . Well, that’s the Kenyan office for you. Glad to be your tour guide. Have a superb day!

• How bad does it look to have left a job soon after starting? [closed]

  - by unitedgremlin

  I have a job I would like to leave. On advice from friends and parents I have stayed. Their primary concern is that it would look bad on my resume if I left only after a few months of joining. My concerns with the job are as follows: When I started it was preferred I provide and use my own equipment. Could be out of business in a few months from lack of cash flow Poor code quality: memory leaks and lack of error handling. The same mistakes continue to be made even though I have raised the issue. It has become evident that co-workers do not understand memory management rules of the platform and are not interested in learning them. Yet, there is still surprise from them when strange bugs continue to crop up. As a result don't feel I will learn from co-workers. Plus, fixing the the lingering bugs and trying to keep up on new feature development is like a game of whack-o-mole that never ends. I don't believe in the companies vision or its ability to execute on the ideas anymore. My ideas and suggestions for very small tweaks are quickly dismissed. And so more than half or so have come back as bugs that we end up needing to address. I have been told to wait on fixing bugs in codes until we can talk to the original author. I don't feel I am allowed to take initiative to just fix/change things and do what I think is best. Everything needs consensus even for a bug fix before any work is done. I am adopting a shut-up and just do what I am told approach to save myself from ulcers. Lots of meetings (I am personally not involved in all of them which is good) but the sheer amount reminds me of days at a big corporation. Why is everyone around me always meeting? It's a small company. I can count everyone on my toes and fingers. I can say with certainty I have no interest in working with any of them again. This is the first time I have truly worked with a group of so called "B and C players". Ultimately, I think it is my fault for not doing a better job evaluating the team and company before joining. But I have generated a better set of questions when probing companies in the future. My questions are: How bad does it look to have left a job soon (few months) after starting? What would be the best way to explain my concerns and reasons for leaving without badmouthing the company? Should I stick it out to what I believe will be the soon end of the company?

• IPv6, isn't it just a few extra bits?

  - by rclewis

  It's always an interesting task, to try and explain what you do to family and friends. I have described IPv6 as the "Next Generation Internet"  or "Second Internet" but the hollow expressions on my kids faces scream for the instant relief of the latest video game.  Never one to give up easily, I have formulated a new example - the Post Office... Similar to the Post Office the Internet delivers mail and packages based on addresses. As the number of residences, businesses, and delivery locations increased, the 5 digit ZIP Code (Washington, DC 20005) was expanded to ZIP+4  allowing for more precise delivery points (Postmaster General, Washington, DC 20260-3100). Ah, if only computers were as simple.  IPv6 isn't an add-on or expansion of the existing IPv4 Addressing, it is a new addressing model which will allow the internet to grow from a single computer in the basement of a university or your parents kitchen table, to support the multitude of smart phones, smart TV's, tablets, dvr's, and disk players, all clambering to connect for information. Unfortunetly there are only a finite number of IPv4 public addresses left, and those are being consumed at an ever increasing rate. Few people could have predicted the explosive growth of the internet or the shortage of IPv4 addresses we now face - but there is a "Plan B" and that is the vastly larger address space of IPv6.  Many in the industry have labeled this a "business continuity" problem,  when in fact most companies will be able to continue conducting business once they run out of existing IPv4 Addresses. The problem is really a Customer Continuity problem, how will businesses communicate with existing customers and reach new customers online who's only option is to adopt IPv6 when IPv4 is depleted? Perhaps a first step is publishing a blog that is also accessible via IPv6, it's just a few extra bits. Join us for the Oracle OpenWorld 2012 Session:   Navigating IPv6 @ Oracle Thursday, Oct. 4th 2:15PM - 3:15PM  Palace Hotel - Concert   Learn more about IPv6 Technologies at Oracle

• Are there software options (preferabbly .NET) for doing distance and speed analysis of footballers moving on video?

  - by Anonymous Type

  Editing Question for Clarity Thanks for feedback so far, very insightful. I'm not sure how far along this part of the software community is, and what if any libraries exist for me to leverage from. Heres what I'm trying to do. Problem: Take an existing video of a game of rugby league. The Rugby League field is 100 metres long, 70 metres wide, and has white line markings every 10 metres running along the width of the field, as well as along the sidelines. Each side has 13 players on the field. Players on each team have identical jerseys that normally constrast strongly against background colours (green/brown field colour) and the referee's colour (usually yellow) and the designated water runner (orange). All players have a unique number in thick white lettering on their backs for identification. Video is taken with a high definition camera. Currently only one camera is used (2D) and existing video does not contain a foreground object of fixed spatial dimensions (as suggested in one answer for comparision measurements, however I could add this to future filming sessions if it is worthwhile). The player's do not run in a straight line 50% of the time but will go sideways on on a diagonal to the play the ball. The distance measured always starts from the spot of the previous "tackle", which ends where the player stops forward movement. It is not always possible to determine the players number from the video (facing other direction, sunlight, others standing in the way of the camera). But this isn't important as the software could allow for manual inputting of unknown "runs" at a later point after analysis. Determine the distance between two points (i.e. where the player started his "run" and where he finished it). I'm guessing that this would be quite doable if I manually marked the start and end point in the video. But how would I use landmarks in the background to determine the distance (assuming the person taking the video has kept it from jerking around). Question: Do software packages or libraries exist that are specialised enough to assist with writing analysis software to determine a sports persons distance travelled based on video taken of the performance?

• Did I choose proper career path? [closed]

  - by Liston Catch

  I am a C# Junior. My company has it's own enterprise documents-flow system written, my job along with 10 other programmers is to write modules/add-ons for it. I am totally bored of this job, I dont like Microsoft's technologies stack (dont hate me here, just subjective), but it's plain boring, enterprise is boring (subjective again, everyone's tastes differ), days on this work last long and I am tired of it. In short - I dont like my job. In my spare time I am doing PHP-development and I totally like it. I am also doing web-design, so I am LAMP-kind of guy who loves his Ubuntu and does design aswell. I know that most programmers don't do design themselves, so some person is either all about design or all about coding, but I enjoy both and do both. I often get interesting sites orders, I love to make whole websites with all the design, I love the feeling of site completeness, I enjoy talking with customers. I like that PHP is simple and skill cap is lower than one of java, meaning I can become expert in it after some years. But C# (and J2EE also) pay more, and I am doing really good in C#. But I dont like it. I can go for J2EE, platform itself seems more fun to me rather than .NET, but EE development is still boring to me. But it seems higher payed, easier to find job (since PHP is too common for its easiness. But if you are expert in something it doesnt matter, right? Just a higher skillcap.) Question: I want to go on with freelance. I want to have an opportunity to start my own startup in web. Actually I have a browser-game already written by myself, it earns me around 500$ per month which I am really proud of since I am 21 only and still noob in coding. I want to find part-time PHP job. 3 days per week so I can get some stable income, I can work in team and learn from them, social factor matters aswell as ensurance and diversity. I also want my total income (freelance + part-time job + own startup maybe)to be not too much less than one I have working in EE development sector. Maximum of 25% lower, but not more. Is it all possible if I stick with web-development (LAMP + HTML/CSS/JS/Jquery/AJAX)? Or is it easier to reach my goals with EE development?

• Could not load file or assembly 'System.Data.SQLite'

  - by J. Pablo Fernández

  I've installed ELMAH 1.1 .Net 3.5 x64 in my ASP.NET project and now I'm getting this error (whenever I try to see any page): Could not load file or assembly 'System.Data.SQLite, Version=1.0.61.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. An attempt was made to load a program with an incorrect format. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

An attempt was made to load a program with an incorrect format. More error details at the bottom. My Active Solution platform is "Any CPU" and I'm running on a x64 Windows 7 on an x64, of course, processor. The reason why we are using this version of ELMAH is because 1.0 .Net 3.5 (x86, which is the only platform for which it's compiled) gave us this same error on our x64 Windows server. I've tried compiling for x86 and x64 and I get the same error. I've tried removing the all compiler output (bin and obj). Finally I've made a reference to the SQLite dll directly, something that was not needed for the project to work on the server and I've got this compiler error: Error 1 Warning as Error: Assembly generation -- Referenced assembly 'System.Data.SQLite.dll' targets a different processor MyProject Any ideas what the problem might be?

• COMException when trying to use a Library

  - by sarkie

  Hi Guys, I have an ASP.net WebService which uses a Library, this has a dependency on some third party .dlls. If I add a reference to the Library to my webservice, I get a COMException and I can't load the site. I thought it may be to do with aspnet user credentials, so I have tried impersonating and using processModel in machine.config but nothing seems to work. The .dlls are for communicating with hardware so I am not even using them on the server just other parts of the library, is there any way I can fix this? I'm running on Windows XP Pro SP3 with Visual 2008 SP1 and .net 3.5. I am thinking the only way of fixing it, is to split up the library into hardware and non-hardware based.

• My VARCHAR(MAX) field is capping itself at 4000; what gives?

  - by eidylon

  Hello all... I have a table in one of my databases which is a queue of emails. Emails to certain addresses get accumulated into one email, which is done by a sproc. In the sproc, I have a table variable which I use to build the accumulated bodies of the emails, and then loop through to send each email. In my table var I have my body column defined as VARCHAR(MAX), seeing as there could be any number of emails currently accumulated for a given email address. It seems though that even though my column is defined as VARCHAR(MAX) it is behaving as if it were VARCHAR(4000) and is truncating the data going into it, although it does NOT throw any exceptions, it just silently stops concatenating any more data after 4000 characters. The MERGE statement is where it is building the accumulated email body into @EMAILS.BODY, which is the field that is truncating itself at 4000 characters. Below is the code of my sproc... ALTER PROCEDURE [system].[SendAccumulatedEmails] AS BEGIN SET NOCOUNT ON; DECLARE @SENTS BIGINT = 0; DECLARE @ROWS TABLE ( ROWID ROWID, DATED DATETIME, ADDRESS NAME, SUBJECT VARCHAR(1000), BODY VARCHAR(MAX) ) INSERT INTO @ROWS SELECT ROWID, DATED, ADDRESS, SUBJECT, BODY FROM system.EMAILQUEUE WHERE ACCUMULATE = 1 AND SENT IS NULL ORDER BY ADDRESS, DATED DECLARE @EMAILS TABLE ( ADDRESS NAME, ALLIDS VARCHAR(1000), BODY VARCHAR(MAX) ) DECLARE @PRVRID ROWID = NULL, @CURRID ROWID = NULL SELECT @CURRID = MIN(ROWID) FROM @ROWS WHILE @CURRID IS NOT NULL BEGIN MERGE @EMAILS AS DST USING (SELECT * FROM @ROWS WHERE ROWID = @CURRID) AS SRC ON SRC.ADDRESS = DST.ADDRESS WHEN MATCHED THEN UPDATE SET DST.ALLIDS = DST.ALLIDS + ', ' + CONVERT(VARCHAR,ROWID), DST.BODY = DST.BODY + '<i>'+CONVERT(VARCHAR,SRC.DATED,101)+' ' +CONVERT(VARCHAR,SRC.DATED,8) +':</i> <b>'+SRC.SUBJECT+'</b>'+CHAR(13)+SRC.BODY +' (Message ID '+CONVERT(VARCHAR,SRC.ROWID)+')' +CHAR(13)+CHAR(13) WHEN NOT MATCHED BY TARGET THEN INSERT (ADDRESS, ALLIDS, BODY) VALUES ( SRC.ADDRESS, CONVERT(VARCHAR,ROWID), '<i>'+CONVERT(VARCHAR,SRC.DATED,101)+' ' +CONVERT(VARCHAR,SRC.DATED,8)+':</i> <b>' +SRC.SUBJECT+'</b>'+CHAR(13)+SRC.BODY +' (Message ID '+CONVERT(VARCHAR,SRC.ROWID)+')' +CHAR(13)+CHAR(13)); SELECT @PRVRID = @CURRID, @CURRID = NULL SELECT @CURRID = MIN(ROWID) FROM @ROWS WHERE ROWID > @PRVRID END DECLARE @MAILFROM VARCHAR(100) = system.getOption('MAILFROM'), DECLARE @SMTPHST VARCHAR(100) = system.getOption('SMTPSERVER'), DECLARE @SMTPUSR VARCHAR(100) = system.getOption('SMTPUSER'), DECLARE @SMTPPWD VARCHAR(100) = system.getOption('SMTPPASS') DECLARE @ADDRESS NAME, @BODY VARCHAR(MAX), @ADDL VARCHAR(MAX) DECLARE @SUBJECT VARCHAR(1000) = 'Accumulated Emails from LIJSL' DECLARE @PRVID NAME = NULL, @CURID NAME = NULL SELECT @CURID = MIN(ADDRESS) FROM @EMAILS WHILE @CURID IS NOT NULL BEGIN SELECT @ADDRESS = ADDRESS, @BODY = BODY FROM @EMAILS WHERE ADDRESS = @CURID SELECT @BODY = @BODY + 'This is an automated message sent from an unmonitored mailbox.'+CHAR(13)+'Do not reply to this message; your message will not be read.'

• Does this code follow the definition of recursion?

  - by dekz

  Hi All, I have a piece of code which I am doubting it as a implementation of recursion by its definition. My understanding is that the code must call itself, the exact same function. I also question whether writing the code this way adds additional overhead which can be seen with the use of recursion. What are your thoughts? class dhObject { public: dhObject** children; int numChildren; GLdouble linkLength; //ai GLdouble theta; //angle of rot about the z axis GLdouble twist; //about the x axis GLdouble displacement; // displacement from the end point of prev along z GLdouble thetaMax; GLdouble thetaMin; GLdouble thetaInc; GLdouble direction; dhObject(ifstream &fin) { fin >> numChildren >> linkLength >> theta >> twist >> displacement >> thetaMax >> thetaMin; //std::cout << numChildren << std::endl; direction = 1; thetaInc = 1.0; if (numChildren > 0) { children = new dhObject*[numChildren]; for(int i = 0; i < numChildren; ++i) { children[i] = new dhObject(fin); } } } void traverse(void) { glPushMatrix(); //draw move initial and draw transform(); draw(); //draw children for(int i = 0; i < numChildren; ++i) { children[i]->traverse(); } glPopMatrix(); } void update(void) { //Update the animation, if it has finished all animation go backwards if (theta <= thetaMin) { thetaInc = 1.0; } else if (theta >= thetaMax) { thetaInc = -1.0; } theta += thetaInc; //std::cout << thetaMin << " " << theta << " " << thetaMax << std::endl; for(int i = 0; i < numChildren; ++i) { children[i]->update(); } } void draw(void) { glPushMatrix(); glColor3f (0.0f,0.0f,1.0f); glutSolidCube(0.1); glPopMatrix(); } void transform(void) { //Move in the correct way, R, T, T, R glRotatef(theta, 0, 0, 1.0); glTranslatef(0,0,displacement); glTranslatef(linkLength, 0,0); glRotatef(twist, 1.0,0.0,0.0); } };

• Improve heavy work in a loop in multithreading

  - by xjaphx

  I have a little problem with my data processing. public void ParseDetails() { for (int i = 0; i < mListAppInfo.Count; ++i) { ParseOneDetail(i); } } For 300 records, it usually takes around 13-15 minutes. I've tried to improve by using Parallel.For() but it always stop at some point. public void ParseDetails() { Parallel.For(0, mListAppInfo.Count, i => ParseOneDetail(i)); } In method ParseOneDetail(int index), I set an output log for tracking the record id which is under processing. Always hang at some point, I don't know why.. ParseOneDetail(): 89 ... ParseOneDetail(): 90 ... ParseOneDetail(): 243 ... ParseOneDetail(): 92 ... ParseOneDetail(): 244 ... ParseOneDetail(): 93 ...

ParseOneDetail(): 100 ... _ <hang at this point> Appreciate your help and suggestions to improve this. Thank you! Edit 1: update for method: private void ParseOneDetail(int index) { Console.WriteLine("ParseOneDetail(): " + index + " ... "); ApplicationInfo appInfo = mListAppInfo[index]; var htmlWeb = new HtmlWeb(); var document = htmlWeb.Load(appInfo.AppAnnieURL); // get first one only HtmlNode nodeStoreURL = document.DocumentNode.SelectSingleNode(Constants.XPATH_FIRST); appInfo.StoreURL = nodeStoreURL.Attributes[Constants.HREF].Value; } Edit 2: This is the error output after a while running as Enigmativity suggest, ParseOneDetail(): 234 ...

• Can compressing Program Files save space *and* give a significant boost to SSD performance?

  - by Christopher Galpin

  Considering solid-state disk space is still an expensive resource, compressing large folders has appeal. Thanks to VirtualStore, could Program Files be a case where it might even improve performance? Discovery In particular I have been reading: SSD and NTFS Compression Speed Increase? Does NTFS compression slow SSD/flash performance? Will somebody benchmark whole disk compression (HD,SSD) please? (may have to scroll up) The first link is particularly dreamy, but maybe head a little too far in the clouds. The third link has this sexy semi-log graph (logarithmic scale!). Quote (with notes): Using highly compressable data (IOmeter), you get at most a 30x performance increase [for reads], and at least a 49x performance DECREASE [for writes]. Assuming I interpreted and clarified that sentence correctly, this single user's benchmark has me incredibly interested. Although write performance tanks wretchedly, read performance still soars. It gave me an idea. Idea: VirtualStore It so happens that thanks to sanity saving security features introduced in Windows Vista, write access to certain folders such as Program Files is virtualized for non-administrator processes. Which means, in normal (non-elevated) usage, a program or game's attempt to write data to its install location in Program Files (which is perhaps a poor location) is redirected to %UserProfile%\AppData\Local\VirtualStore, somewhere entirely different. Thus, to my understanding, writes to Program Files should primarily only occur when installing an application. This makes compressing it not only a huge source of space gain, but also a potential candidate for performance gain. Testing The beginning of this post has me a bit timid, it suggests benchmarking NTFS compression on a whole drive is difficult because turning it off "doesn't decompress the objects". However it seems to me the compact command is perfectly capable of doing so for both drives and individual folders. Could it be only marking them for decompression the next time the OS reads from them? I need to find the answer before I begin my own testing.

• Overheating computer

  - by Samurai Waffle

  My computer overheats somewhat frequently, usually during intense use. And by intense use I mean browsing the internet while downloading, or gaming. It even overheats on extremely old games though, Master of Orion 2, which was developed for Windows 95. My computer has a Pentium 4 Ghz processor, 2 GB of ram, and is running Windows XP. One of the symptoms it has after overheating, is that it'll turn on immediately afterwards, but won't show any video on my monitor. I usually have to wait at least 5 minutes (mostly at least 10) before I can get it to turn on and show video on my monitor. I also usually have to wiggle around the graphics card a little bit, which is the ASUS A9550 Series with 256 MB. I'm not sure exactly what is causing the computer to overheat. At first I thought it was the video card, but after I noticed it was doing it while playing Master of Orion 2, I'm not so sure, because that game can't be making the video card work all that hard. So how exactly can I pinpoint the problem? Thanks for any help provided. Edit: Okay I downloaded the programs that you specified, and will start benchmarking my system to try and pinpoint what's overheating. What is the temperature range for when it's getting to hot? Also I have an abundant amount of software experience with computers, but unfortunately not to much hardware experience.

• Intel Core i7 QuadCore on HP Pavilion dv7 Overheating Issues

  - by kellax

  I bought a brand new HP notebook: HP Pavilion dv7-6b21em BeatsAudio edition. The notebook is about 2 months old and has pretty nasty overheating problem. I mainly use it for development however i do play some games. The disturbing thing is that the computer is loud on pretty simple tasks. Here are the specs: CPU: Intel Core i7-2670QM QuadCore ( 8 threads ) @ 2.20 GHz RAM: ( 8GB ) 2x 4GB @ 1066 HDD: 1TB 7200 GPU: ATI Radeon HD 6770M 1GB Dedicated DDR OS: Windows 7 64bit Enterprise I have an external monitor runing on VGA port an 22' Samsung SyncMaster S24B300 CPU Heat Statistics Platform: rPGA 988B (Socket G2) Frequency: cca. 3000 Mhz VID: 1.1809 - 1.2059 v Revision: D2 CPUID: 0x206A7 TDP: 45.0 Wats, Lithographu: 32 nm Heat: Tj. Max: 100*C, Power 4.5 - 5.9 Wats Core #0: 63*C Load on all is about 0 to 2% Core #1: 65*C Core #2: 66*C Core #3: 67*C I opened the notebook the fan is working fine there is no dust but still right now the fan is pretty loud even tho all i have open is FireFox. When i run a game the heat jumps to whopping 90-97*C. It has not shut down due to overheating yet but the loud fan is pretty annoying considering I'm not really doing anything stressfull. Is there anything i can do to fix this is it maybe a BIOS issue ? I have all drivers updated tho to the latest. I have very few background processes running consuming bare 2GB of RAM and about 2% of CPU. I had it serviced they said there is nothing wrong with it. But i feel that a Notebook that costs 1.2k Euros cant be like this.

• Is there a way to tell what the download speed is from a site/server

  - by Memor-X

  i'm looking into which ISP i should go with at the place i'm moving into, one ISP which i have been told good things about has data limits (which when breached will drop your speed to dial-up speed) but multiple memberships which, apart from the cheapest membership, have the same data limits (the cheapest has a 10GB data limit) in their fine print, they say that each different membership has different port speeds, one particular part jumps out at me These speeds are the NBN (National Broadband Network) port speed and not the actual Internet data speed which will vary based on numerous factors including destination you are reaching, your network equipment, network congestion etc. i plan to use the net to download DLC and patch updates for games (particular the insanely large update for the Wii U) and games from Steam (if i find any good one other than this one JRPG) and downloading development resources from free sites like Deposit Files and Mediafire since one membership with a 1000GB data limit is $145 with the port speed being 12Mbps/1Mbps (cheapest) while another with the same limit is $190 with the port speed of 100Mbps/40Mbps (expensive) i am wondering how i can tell what the speed coming from site is since i don't want to be wasting money on speed that makes no difference (unlike memory which i rather have to spare) NOTE: the speeds are for a fiber optic network which where my new place is can only connect via fixed wireless which i may not be able to get with this ISP but if i can get this network then good NOTE 2: most of the resources i get from Deposit Files are always about 200 MB or less, if a resource pack is greater then it's split into multiple archives (like .7z.part) while Mediafire i have to see one bigger than 150MB NOTE 3: one update patch for a PS3 game is close to 4 GB (Disgaea 4) which i need to get access to the DLC and on the weekend i downloaded 5 GB for the Final Fantasy XIV Open Beta for the PS3 which took almost 5 hours

• How to lock Windows7 from installing anything.

  - by Andy

  A family member continually needs me to reinstall his PC after it gets viruses and spyware. He claims that he never downloads anything but evidence suggests otherwise. Unless there is some way that watching 'videos' can get spyware on there. AFAIK the computer is kept up to date. Possible solutions? Make a login where its impossible for him to install anything. Windows 7 standard account doesn't appear to be enough. Is a standard account enough here? I tried this once before and he still seemed to get IE toolbars installed up the wazoo Somehow make an automated image where if he 'messes up' or even on log off the computer restores the whole drive image. Similar to what I've seen in Kinko's Something I've not thought of.... And I know you are all going to say 'stop fixing it you are an enabler'... yes I know but I'm not going to have another fight with my wife over helping her family... right now I'm doing this to keep her happy not the idiot with the 'video' addiction ;-) So the name of the game is minimizing my overhead.

• Server and Network Lag

  - by DanSpd

  At my home I have a server and my computer. Server has Windows Server 2008 Standart 64 bit installed and then my computer has Windows 7 64 bit installed. My home router is DIR-615 My server has a game server installed on it and basically total open connections on server are around 700. Once its around 700 server and then whole home network lags really badly. My internet connection is good and only around 600kb/s is being used out of 2mb/s (real download/upload speeds). So far I assume that my router has a connection limit and with server + my computer connections it peaks at around 1k and lags everything. Another assumption server lag comes from connection limit. On the internet I have read that standart version of server has connection limit of 700 + 10 reserved. I do not rmember where I found that information but it was on microsoft website. So I have two options. First is to upgrade my router to Netgear FVS318G-100 and second is to change connections limit on server. Any advices? Thank you

• Files Corrupted on System Restore

  - by Yar

  I restored OSX 10.6.2 today (was 10.6.3 and not booting) by copying the system over from a backup. The data directories were not touched. I am seeing some files as 0 bytes, and getting permission-denied errors when copying, even when using sudo cp or the Finder itself. Some programs, differently, take the files at face value and see no permission problems (such as zip), but they see the files as zero bytes, which would be game-over for recovery. cp: .git/objects/fe/86b676974a44aa7f128a55bf27670f4a1073ca: could not copy extended attributes to /eraseme/blah/.git/objects/fe/86b676974a44aa7f128a55bf27670f4a1073ca: Operation not permitted I have tried sudo chown, sudo chmod -R 777 and sudo chflags -R nouchg which do not change the end result. Strangely, this is only affecting my .git directories (perhaps because they start with a period, but renaming them -- which works -- does not change anything). What else can I do to take ownership of these files? Edit: This question comes from StackOverflow because I originally thought it was a GIT problem. It's definitely not (just) GIT. Anyway, this is to help put some of the comments in context.

• Port forwarding + shared connection with Ubuntu

  - by Joey Adams

  Because my wireless router's ethernet ports are defective, I set up a shared wireless connection from my laptop (which has wifi) to my eMac (which does not) via a crossover ethernet cable. The laptop is behind a router as 192.168.1.131, and the eMac is behind the laptop as 10.42.43.1 . The laptop is running Ubuntu 9.10 (Karmic). I achieved the shared connection through NetworkManager Applet. I right-clicked on the network icon at the topright, went to Edit Connections, selected the Wired connection named "Auto eth0", clicked "Edit...", went to the "IPv4 Settings" tab, and selected the Method "Shared to other computers". The eMac can now access the Internet. Now I want to enable port forwarding. There's a game I want to play that needs port 6112 forwarded (both TCP and UDP) in order to host games. I set up the router to enable port forwarding for 192.168.1.131 (the laptop), but port forwarding still isn't available on the eMac. I suppose I need to pretend my laptop is a router and configure port forwarding on it, indicating that incoming connections to the laptop (192.168.1.131) should be forwarded to the eMac on the shared connection (10.42.43.1 ). Thus, packets coming into the router on port 6112 would be redirected to the laptop (by the router), then to the eMac (by the laptop). My question is, how would I do that on Ubuntu (in light of NetworkManager's presence)? Also, if I can't get this to work, does anyone mind hosting a comp stomp? :D

• Is there any way for ME to improve routing to an overseas server?

  I am trying to make a connection to a gaming server in Asia from Australia, but my ISP routes my connection through the US.

Since I think it will be unlikely that my ISP will do anything, are there any ways to improve my routing to the server without them having to intervene? NB. The game runs predominately over UDP, so I believe most low ping services are out of the question, as they rely on TCP traffic.

• Why does my computer crash randomly?

  - by Donavon Decker

  The other day I went out to my van to get my Tower and when I opened the trunk it fell out. I brought it into the house and opened it, and everything looked ok. When I started it up, about 1-3 minutes afterwards it would crash. It did this over and over until I reseated the cooler. Everything seemed normal again, until after about 10 minutes of gameplay (any game), it would crash. I reseated my GPU + reinstalled the drivers, however I still get the same error. A while back, I'd check my 'Windows Rating' periodically, and all of them were in the '6.0-6.9' range except for my hard disk usage (always been like that [not relative]). Today I went in and looked, and my Processor and Memory was rated 5.4. I reseated my cpu and my memory, refreshed the windows rating, and then my processor and memory went from 5.4, to 5.1. A few minutes ago I reseated them once again, and now it's back to 5.4. Note: Not sure if this is relevant to the issue, but I updated my bios earlier today I honestly have no idea what the issue is, but I'm getting aggravated at the problem. Here are some images which contain images of my specifications: i1271.photobucket.com/albums/jj623/donxdeck/1_zps09f0607c.jpg i1271.photobucket.com/albums/jj623/donxdeck/4_zps381cd00a.jpg i1271.photobucket.com/albums/jj623/donxdeck/3_zps54bba720.jpg i1271.photobucket.com/albums/jj623/donxdeck/2_zps945d3d72.jpg Thanks for the help

• Computer randomly freezes when playing games

  - by TutorialPoint

  My computer just randomly freezes when playing certain games. It has happened to me in Battlefield: Bad Company 2, Call of Duty 4, and Blacklight: Retribution. It has not happened to me with other games like Tribes: Ascend yet, which leads me to believe it is a software-side issue related to maybe DirectX or PhysX? Also, temperatures seem stable. I used RivaTuner combined with MSI Afterburner, and at the time of freezing with BF:BC2, it gives: 62C, 67% GPU usage and 78.8FPS. During the session the max I have seen was 65C and 97% GPU usage. On Blacklight: Retribution, I've heard other people complain about the problem too. This is why it is such a mystery to me, is this actually a driver problem, or more a game problem? I've been able to play these games for long until I re-installed Windows 7 (because it was growing too full and slow). Before I had a 32bit Ultimate version, and now 64bit. Specs: O/S: Windows 7 64bit Ultimate CPU: Intel i5-750 @ Default 2.66 GHz GPU: ASUS EAH5770 1GB PSU: CoolerMaster Real Power M520 (520W) MB: Gigabyte P55M-UD2 Catalyst Control Center version (in "About"): 2012.0214.2218.39913
