  • Terrible Performance with SATA Drives on Dell PowerEdge, steps to troubleshoot?

    - by Tom
    I had asked this question earlier and the question went missing so here it is again. Bought a DELL Poweredge 2950 to use as in-house QA Server. Disk performance is beyond terrible, 1000-4000 ms response time on the drive with our SQL Server database .mdf. Sql Server disk queue upwards of 300 at times. I'm a software guy, can anyone help me with steps to determine the issue? I don't know what RAID controller it has, how can I determine that? I'm speculating it could be BIOS issue. Perhaps the server used to have another kind of drive in it and when I added SATA the ??? buffer size is wrong??? Perhaps I chose wrong options (chose defaults) when setting up the RAID 1 arrays? I thought RAID 1 was a performance array?

  • Laser range finder, what language to use? Beginner advice

    - by DrOnline
    I hope this is the right place. I am a programming beginner, and I want to make a laser range finder, and I need advice about how to proceed etc. In a few weeks I will get a lot of dirt cheap 3-5V lasers and some cheap usb webcams. I will point the laser and webcam in parallel, and somehow use trigonometry and programming to determined distance. I have seen online that others made done it this way, I have purposefully not looked at the details too much because I want to develop it on my own, and learn, but I know the general outline. I have a general idea of how to proceed. The program loads in a picture from the webcam, and I dunno how images work really, but I imagine there is a format that is basically an array of RGB values.. is this right? I will load in the red values, and find the most red one. I know the height difference between the laser and the cam. I know the center dot in the image, I know the redmost dot. I'm sure there's some way to figure out some range there. TO THE POINT: 1) Is my reasoning sound thus far, especially in terms of image analysis? I don't need complete solutions, just general points 2) What I need to figure out, is what platform to use. I have an arduino... apparently, I've read it's too weak to process images. Read that online. I know some C I know some Python I have Matlab. Which is the best option? I do not need high sampling rates, I have not decided on whether it should be automated or whether I should make a GUI with a button to press for samples. I will keep it simple and expand I think. I also do not need it to be super accurate, I'm just having fun here. Advice!

  • How to give credit about an image I display in my website?

    - by Erel Segal Halevi
    I looked for an image for decorating the main page of my website. I found a great image in Wikipedia. The license allows me to use the image, but, I must give credit to the creators (which includes their name and a link to their Flickr page). My question is: what is the best way to give credit about the image, such that the page design will not be harmed? In case it matters: my page is very simple - it contains only the image (floated right), a heading, a small amount of text, and some links. But, my question is more general and probably applies to many different websites.

  • Is good practice to optimize FPS even when it's above the lower limit to give illusion of movement?

    - by rraallvv
    I started over 50 FPS on the iPhone, but now I'm bellow 30 PFS, I've seen most iPhone games clamped to either 60 or 30 FPS, even when 24 or less would give the illusion of movement. I've concidered my limit to be a little bit over 15 FPS, in fact my physics simulation is updated at that rate (15.84 steps/s) as that is the lowest that still give fluid movement, a bit lower gives jerky motion. Is there a practical reason why to clamp FPS way above the lower limit? Update: The following image could help to clarify I can independently set the physic simulation step, frame rate, and simulation interval update. My concern is why should I clamp any of those to values greater than the minimum? For instance to conserve battery life I could just to choose the lower limits, but it seems that 60 or 30 FPS are the most used values.

  • Contract Programming - Deposit % and Payment Methods? Any advice is appreciated

    - by Rick
    I'm pretty new to doing contract work and finally landed a decent paying project. The guy actually offered to put down a deposit and I'm just wondering what percentage I should consider asking for. I was thinking around 25% since its not a terribly large project (only about 20 hours). Also, I can't use PayPal (have had a terrible experience with them freezing funds for no good reason) so I'm wondering if anyone can suggest other methods for the client to send the deposit / payment. I want to make it as easy as possible for them.. thanks for any advice

FAILED [LOW] LowMaxReadReq: Test 1, 2 devices have low MaxReadReq settings. Firmware may have configured these too low. ADVICE: The MaxReadRequest size is set too low and will affect performance. It will provide excellent bus sharing at the cost of bus data transfer rates. Although not a critical issue, it may be worth considering setting the MaxReadRequest size to 256 or 512 to increase throughput on the PCI Express bus. Some drivers (for example the Brocade Fibre Channel driver) allow one to override the firmware settings. Where possible, this BIOS configuration setting is worth increasing it a little more for better performance at a small reduction of bus sharing. ==================================================================================================== PCIe ASPM check. ---------------------------------------------------------------------------------------------------- Test 1 of 2: PCIe ASPM ACPI test.

Which one is healthier or easier considering this is just a local test website, configuring apache to give user logan to view website and chmod /var/www logan:logan so that I can create files etc. without any sudo commands; or is it easier to configure user groups to get www-data user to act like my logan user?

  • "Don't do programming after a few years of starting career". Is this a fair advice?

    - by Muhammad Yasir
    I am a little experienced developer having approximately 5 years experience in PHP and somewhat less in Java, C# and trying to learn some Python nowadays. Since the start of my career as a programmer I have been told every now and then by fellow programmers that programming is suitable for a few early years of a career (most of them take it as 5 years) and that one must change the direction after it. The reason they present include headaches and pressures associated with programming. They also say that programmers are less social and don't usually like to give time to their families, etc. and especially "Oh come on, you can not do programming your entire life!" I am somewhat confused here and need to ask others about it. If I leave programming then what do I do?! I guess teaching may be a good option in this case, but it will require to first earn a PhD degree perhaps. It may also be noteworthy that in my country (Pakistan) the life of a programmer is not very good in that normally they must give 2-3 extra hours in the office to accomplish urgent programming tasks. I have a sense that situation is somewhat similar in other countries and regions as well. Do you think it is fair advice to change career from programming to something else after spending 5 years in this field? UPDATE Oh wow... I never knew people can have 40+ years of experience in this field. I am both excited and amazed seeing that people are doing it since 1971... That means 15 years before my birth! It is nice to be able to talk to such experienced people, we don't get such a chance here in Pakistan.

  • UDK/ UnrealScript class interaction? HUD advice?

    - by Holly
    Beginner basics requested here, While i'm familiar with the basics of OOP programming i've just started looking as UnrealScript for a game i had made in the UDK editor up to now. I have a class that extends UTHUD and another that extends UDKPAWN. I have the pawn destroyed when its been shot 3 times and some basic helloworld text displaying in my HUD but i'm completely lost as to how one would get some sort of feedback between the two classes going on? What i would like to do to start off, is have some text that says something like "Amount of baddies killed: 0" Displayed on the HUD which would then increment each time the player destroyed one of my pawns. I'm sorry if this is an inappropriate question but i've never really worked within a framework like this before and wasn't sure where to go for help to get my footing. All advice appreciated!

  • Computer Science Career Advice: Master's in Computer Science vs. Software Engineering?

    - by Everton
    Hello, I am a college student and I am majoring in Computer Science and Applied Mathematics. As I get closer to my senior year I have noticed that continuing my studies is the best choice right for me now. I see that several universities offer an Computer Science Master's Degree and an Software Engineering degree. What are their pros and cons? I feel that while the Computer Science master's degree seems a little too broad the Software Engineering is too restrictive. I did not decide yet between an career of Software development or research ( algorithm development among other things ). Any advice would be greatly apreciated!

  • What's your advice for getting Oracle Certified Professional Java Programmer certificate?

    - by den-javamaniac
    Hi. I intend to get the certification but am not completely sure how to effectively prepare myself. So I'm wondering if you have any advice on the matter; in particular I would like to know: - What should the basic learning/practicing plan look like? - Which book (set of books) should be considered? - Which practical exercises should be performed? NOTE: I've got several years of corporate experience (mostly web apps, though), but I want to be 100% sure I'll pass the test (that's the reason the issue is raised).

  • Can I get some advice on graphics cards please?

    - by Victor9098
    I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

Because I already know the RSA key, I would prefer to see the RSA key presented at this point.

  • Advice on selecting programming languages to concentrate on? (2nd year IT security student)

    - by Tyler J Fisher
    I'm in the process of considering which programming languages I should devote the majority of my coding studies to. I'm a 2nd year CS student, majoring in IT security. What I want to do/work with: Intelligence gathering Relational databases Virus design Snort network IPS Current coding experience (what I'm going to keep): Java - intermediate HTML5 - intermediate SQL (MySQL, Oracle 11g) - basic BASH - basic I'm going to need to learn (at least) one of the following languages in order to be successful in my field. Languages to add (at least 1): Ruby (+Metasploit) C++ (virus design, low-level driver interaction, computationally intensive applications) Python (import ALL the things) My dilemma: If I diversify too broadly, I won't be able to focus on, and improve in a specific niche. Does anyone have any advice as to how I should select a language? What I'm considering + why I'm leaning towards Ruby because of Metasploit support, despite lower efficiency when compared to Python. Any suggestions based on real-world experience? Should I focus on Ruby, Python, or C++? Both Ruby, and Python have been regarded as syntactically similar to Java which my degree is based around. I'm going to be studying C++ in two years as a component of my malicious code class. Thanks, Tyler

  • Advice for programming a lobby for a network multiplayer game?

    - by Milo
    I'm working on learning network programming. I'm working on a simple card game. The basic idea is: Players enter the lobby Players see tables Players sit at an empty seat Once they sit, they do not need any information from the lobby, they see the card table and the data about the other players and so forth. I've programmed the server portion for the game itself. The clients connect to my server object and the server then receives and sends messages; quite simple. The tricky concepts for me are: What's a good way to run many tables at the same time? What's a good way to keep the lobby consistently updated for each person in the lobby (eg: MSG_TABLE_FILLED, 22) Ideally I'd like to have 1 server exe for all of this and to have to deal with multithreading as little as possible. I'm going to use the enet library. I was thinking that each time a game session starts, I push a new Game and I map the client IPs to that table, then I just route messages from those clients to that Game. Since enet supports channels I was thinking of using 2 channels per table, one for the game messages and one for in game chat. Would something like this work? Does anyone have any advice / design ideas for a game with a lobby and many tables? Is there a usual way this is done that I'm overlooking? Any conceptual ideas or even c/c++ code examples would be very helpful. Thanks

  • Architecture advice for converting biz app from old school to new school?

    - by Aaron Anodide
    I've got a WinForms business application that evolved over the past few years. It's forms over data with a number custom UI experiences taylored to the business, so I don't think it's a candidate to port to something like SharePoint or re-write in LightSwitch (at least not without significant investment). When I started it in 2009 I was new to this type of development (coming from more low level programming and my RDBMS knowledge was just slightly greater than what I got from school). Thus, when I was confronted with a business model that operates on a strict monthly accounting cycle, I made the unfortunate decision to create a separate database for each accounting period. Also, when I started I knew DataSets, then I learned Linq2Sql, then I learned EntityFramework. The screens are a mix and match of those. Now, after a few years developing this thing by myself I've finally got a small team. Ultimately, I want a web front end (for remote access to more straight up screens with grids of data) and a thick client (for the highly customized interfaces). My question is: can you offer me some broad strokes architecture advice that will help me formulate a battle plan to convert over to a single database and lay the foundations for my future goals at the same time? Here's a screen shot showing how an older screen uses DataSets and a newer screen uses EF (I'm thinking this might make it more real for someone reading the question - I'm willing to add any amount of detail if someone is willing to help).

  • Ask the Readers: Would You Be Willing to Give Windows Up and Use a Different O.S.?

    - by Asian Angel
    When it comes to computers, Windows definitely rules the desktop in comparison to other operating systems. What we would like to know this week is if you would actually be willing to give up using Windows altogether and move to a different operating system on your computers. Note: This week’s Ask the Readers post is posing a hypothetical situation, so please refrain from starting arguments or a flame war in the comments. Good reasoned discussion is always welcome. There is no doubt that Windows is the dominant operating system in use today. Everywhere you go or look it is easy to find computers with Windows installed such as at work, home, the library, government offices, and more. For many people it is the operating system that they know and are comfortable with, which makes changing to a different operating system less appealing. Adding to the preference for Windows (or dependency based on your view) is the custom software that many businesses use on a daily basis. Throw in the high volume of people who depend on and use Microsoft Office as a standard for their business documents and it is little wonder that Windows is so dominant. So what would you use if you did decide to take a break from or permanently move away from Windows? If your choice is Linux then you have a large and wonderful variety of distributions to choose from based on what you want out of your system. Want a distribution that is easy to work with? You could choose Ubuntu, Linux Mint, or others that are engineered to be ready to go “out of the box”. Like a challenge? Perhaps Arch Linux is more your style. One of the most attractive features of all about Linux is the price…it is very hard to beat free! Maybe Mac OS X sounds like the perfect choice. It has a certain mystique and elegance associated with it and many OS X fans refuse to use anything else if given a choice. Then there is the soon to be released Chrome OS with its’ emphasis on cloud computing. This is a system that is definitely focused on being as low-maintenance and hassle-free as possible. Quick on, quick off, minimalist, and made to be portable. All of the system’s updates will occur automatically leaving you free to work and play in the cloud. But it does have its’ limitations…no installing all of those custom apps that you love using on Windows or other systems…it is literally all about the browsing window and web apps. So there you have it. If the opportunity presented itself would you, could you give Windows up and use a different operating system? Would it be easy or hard for you to do? Perhaps it would not really matter so long as you could do what you needed or wanted to do on a computer. And maybe this is the perfect time to try something new and find out…that new favorite operating system could be just an install disc away. Let us know your thoughts in the comments!

  • I'm hoping to start an online supermarket and needs advice on open source shopping cart software and applications..

    - by Betterman Simidi
    I have been researching on both open source software and off-the-shelf software for an online supermarket project in Africa. I have now narrowed by search to X-cart and the PHP based PrestaShop shopping carts. My plan is to acquire an open source shopping cart either by purchasing or as a free open source cart and hire a local developer to customize it to our local needs. I have been doing the demo for x-cart for three weeks now and had thought it might work best for us but after going through the 600 page manual and I'm concerned with how far it can be localized. Yesterday i was looking at the possible Prestashop free open source cart and i seem to like the back-end. Didn't like the back-end for Magento much but from reviews conducted by third-parties they seem to recommend it. I'm now wondering whether i should have a developer start the whole project from scratch, or use an open source software such us PrestaShop or get x-cart which can then be customized. Note that my store will have thousands of products and services including groceries and so i want something that can handle upto 500,000 products and over. Kindly advice. 93276

  • Java or Python? Career/Start-up advice needed [closed]

    - by vim
    I have a full-time PHP job and I've been working with PHP for 5 years. As you can guess after spending 5 years I'm not willing to stay within this technology stack any more. I also worked with Java for 2 year before, so for me it looks more obvious to switch back to Java. However during last 5 years I was thinking about starting my own project, and now I think I have a very good SAAS idea. I'm completely confused what technology should I use for my project. I don't want to do it in PHP, and after reading many articles about rapid prototype development it seems to me that Django/Ruby is the best option. I will continue to work full time for my current employer because I need to pay my bills and will work on my project in my free time. The concern I have is should I do my project in Java or Python? To be realistic there is always a risk when you are doing your own project/start-up. If I do it in Java in the worst case scenario I believe I will be able to find a full time Java position because I already have some experience in Java + recent experience in my project. With regards to Python it looks like it is not very popular in my area and salaries are much more lower then for Java. On the other hand I have a feeling that if I chose Java it will take me a way longer to finish my project. Guys I'm completely confused and I need your advice. P.S. I have moved to London 2 years ago from another country, local guys are very welcome to share their thoughts about London's job market.
