  • Is putting swapfile & temp folder in ramdisk a good idea in Windows 7 64 bit with lots of ram?

    - by Tony_Henrich
    I want my Windows to run as fast as possible. If I have 12GB ram in Windows 7 64bit, quad core cpu, and all apps fit in memory, will the swap file ever be used for anything? The question is about if its a good idea to put the swap file in a ram disk. Would a ram disk help in any way or will Windows intelligently use all the available memory for all its work? I am also thinking of putting the temp folder in a ram disk. I know ram disk is volatile memory and I don't care about its content in it if it gets lost.

  • Does the direction of storage make us bad data citizens?

    - by simonsabin
      My career started at a company where we hardly had email, the network was a 10base2 affair with cables running all around the office. You used floppy disks and the thought of a GB of data was absurd. You had to look after every byte and only keep what you really needed. Whilst the cost of the spinning disks gradually falls the cost and size of flash storage continues to plummet. The new Crucial SSD is £380 for 1TB I can now keep 128GB of data on a SD card the size of my finger. It only costs...(read more)

  • Can an Employer turn you down if you have said the fact about current work culture being bad [closed]

    - by MansonRix
    I had recently an interview where I scored good in 1st two round of technical interview . Then in the 3rd round was the managerial round where the guy started about my experience and whether I have vaptured any requirement and handled and trained any teams. This went pretty well for around 50 mins . Then there was the awkward question , Interviewer: why amI looking for a change? Me: coz I want to explore my carrier options? Interviewer: But your current company is big enough and you can explore options over there? (This was supposedly the trap) Me: Apart from that I am missing the flexibilty of working with Us and Europe based company as my current company is not that flexible. Interviewer: What exactly you don't find flexible. Me: The login time . Even if you get late by 1sec you might have to explin. Though this is not a big problem , still I will prefer flexibilty as we are working really hard. Interviewer: Allright ( Then couple of more questions) , Hope to C U Ya , that's pretty much it . Now I called up HR and they say , they are yet to get the feedback from Interviewer. Did I screw it? I mean does some one really have to pretend always by saying positive things about company and manager though not saying negative things?

  • Is `catch(...) { throw; }` a bad practice?

    - by ereOn
    While I agree that catching ... without rethrowing is indeed wrong, I however believe that using constructs like this: try { // Stuff } catch (...) { // Some cleanup throw; } Is acceptable in cases where RAII is not applicable. (Please, don't ask... not everybody in my company likes object-oriented programming and RAII is often seen as "useless school stuff"...) My coworkers says that you should always know what exceptions are to be thrown and that you can always use constructs like: try { // Stuff } catch (exception_type1&) { // Some cleanup throw; } catch (exception_type2&) { // Some cleanup throw; } catch (exception_type3&) { // Some cleanup throw; } Is there a well admited good practice regarding these situations?

  • LSI 9260-8i w/ 6 256gb SSDs - RAID 5, 6, 10, or bad idea overall?

    - by Michael Pearson
    We're provisioning a new production server for our reasonably busy website. Our choice of host have available a 6 drive configuration with a LSI 9260-8i card. My initial thought was to fill all six bays with SSDs (Intel 520 256gb) and set them up in RAID. Good, bad, or terrible idea? Can the card handle it? Should we be using RAID 5, 6 or 10? This would be the first time the provider have filled all six slots for this rackmount with SSDs, so they're a bit hesitant. I'm wondering if somebody else with this card has done something similar in a production environment. We do about 43gb of writes per day and currently use about 300gb of storage. The server acts as webserver, database, and image store for approx 1 million files. The plan is to underprovision the SSDs by approximately 10% to 20% to increase their overall lifespan & performance. The fallback option is 2x480gb SSDs in RAID 1 and another 2x1TB HDDs in RAID 1. The motivation behind this is that the server rental cost difference between 2xSSDs and 6xSSDs is minimal (compared to the overall cost of the rental). We do not have any special high-IOPs requirements. However, if the configuration is known to work, I don't see a good reason to not use it and not have to worry about having separate 'fast and small' and 'slow and large' disks.

  • Is it bad to have the Reverse DNS for two IPs point to the same domain name?

    - by Daniel Vandersluis
    I am in the process of setting up a new server for my domain (the site will be moved, it is not for load balancing or the like), which has a different IP address from my existing server. My current server has a reverse DNS PTR record set up pointing its IP to mydomain.com. Is it bad to set up a reverse DNS PTR record for the new IP pointing to mydomain.com as well? Or should I wait until I do my migration to set up the record?

  • Two cisco gigabit switches refuse to link to each other. Any idea why?

    - by Prody
    I have 3 Linksys SR2024 switches which are basically non-managed 24 port Gbit + 2 miniGBIC. I now had to add another switch to the network, and my provider didn't have the SR2024 switch anymore, so I got the Cisco SLM2024 which was a bit more expensive. It's pretty much the same thing but with management (that I don't need). So I've connected the SLM2024 to a SR2024 via Cat6 cable, and for some strange reason, I get no link. If I connect any machine with a Gbit NIC to both switches, it links with 1Gbit autonegotiated. If I connect the SLM2024 to a non-Gbit switch (I have a cheap 4port ASUS switch), it will link just fine on 100Mbit full duplex. Since the SLM2024 has management, I've tried to see if something is misconfigured on it's side, but it's not, it advertises 1Gbit and lower. (hence the machines connecting succesfully at 1Gbit). Since the SR2024 that I'm trying to connect it to also connects successfully with another SR2024 and other Gbit machines, it means that it advertises Gbit too. But for some reason when I link the SR2024 to the SLM2024 I get no link. Please note that I've properly tested the wire. Does anyone have any idea what's wrong?

  • Is it a bad idea if equals(null) throws NullPointerException instead?

    - by polygenelubricants
    The contract of equals with regards to null, is as follows: For any non-null reference value x, x.equals(null) should return false. This is rather peculiar, because if o1 != null and o2 == null, then we have: o1.equals(o2) // returns false o2.equals(o1) // throws NullPointerException The fact that o2.equals(o1) throws NullPointerException is a good thing, because it alerts us of programmer error. And yet, that error would not be catched if for various reasons we just switched it around to o1.equals(o2), which would just "silently fail" instead. So the questions are: Why is it a good idea that o1.equals(o2) should return false instead of throwing NullPointerException? Would it be a bad idea if wherever possible we rewrite the contract so that anyObject.equals(null) always throw NullPointerException instead?

  • Is it ever a bad idea to publish a sitemap for a blog?

    - by mipadi
    I have a blog, and I have been considering publishing a sitemap for it, which would include the index page, archives page, and an entry for each individual blog post. Is this ever a bad idea? Is it a good (or useful) idea? I'm particularly interested in the <changefreq> element: I edit posts from time to time, and while that's not a common occurrence, I don't want to set a particularly infrequent change frequency that prevents search engines like Google from indexing the edits. (The sitemaps protocol says that search engines may still crawl the pages more frequently, but has no further details on the matter.)

  • What do you do when every possible business idea is already taken?

    - by jonathanconway
    I have a bit of free time and lots of enthusiasm for software and the web. I want to make a start-up, to sell kind of product or online service, but I'm having a hard time coming up with business ideas that haven't already been implemented. For example, I thought of making an e-ordering website for ordering food from restaurants online. Good thing I typed it into Google, because the market is already full of hundreds of websites doing the same thing and competing heavily. The same thing has happened with so many other business ideas I've become excited and passionate about - they're all taken. What's your response to this? Do you agree that all the good ideas seem to be taken? Or do you think there is room for new businesses, and that I'm just not thinking (or looking) hard enough? Have you ever tried idea after idea, only to find that it was already being done, and you had to move onto something else?

    Is there any idea not to select the name that is already choosen in token input? for example In first i select mango when i search for m. Next time again when i search for m Mango should not be displayed as mango is already choosen. Is there any idea? <%= f.text_field :plan_tokens, data: {load: @customer.plans} %> I study this from I have my js like this jQuery - $('#customer_plan_tokens').tokenInput '/plans.json' theme: 'facebook' prePopulate: $('#customer_plan_tokens').data('load') where to put preventDuplicates:true.

  • is it a good idea to write tests for environments other than development?

    - by jcollum
    Let's say I have a (fairly typical) set of environments: PROD, UAT, QA, DEV. Is it a good idea to run your tests across all environments? Here's what I'm thinking of. I have a proc in SQL that my code depends on, I'll call it proc_getActiveCustomers. If that proc isn't present my app will go south real fast. So I write a test that checks for the existence of this proc in the database. Nothing new here. But when I then deploy my app to the QA environment, would I also want to have a test that checks that environment for the existence of proc_getActiveCustomers? I think this is a good idea but I've never heard much about testing in environments outside of development. Makes me wonder if there's some downside I'm not aware of. The direction that I'm going is to have a list of environments in code and then passing that environment into my unit test.

  • Are background threads a bad idea? Why?

    - by Matt Grande
    So I've been told what I'm doing here is wrong, but I'm not sure why. I have a webpage that imports a CSV file with document numbers to perform an expensive operation on. I've put the expensive operation into a background thread to prevent it from blocking the application. Here's what I have in a nutshell. protected void ButtonUpload_Click(object sender, EventArgs e) { if (FileUploadCSV.HasFile) { string fileText; using (var sr = new StreamReader(FileUploadCSV.FileContent)) { fileText = sr.ReadToEnd(); } var documentNumbers = fileText.Split(new[] {',', '\n', '\r'}, StringSplitOptions.RemoveEmptyEntries); ThreadStart threadStart = () => AnotherClass.ExpensiveOperation(documentNumbers); var thread = new Thread(threadStart) {IsBackground = true}; thread.Start(); } } (obviously with some error checking & messages for users thrown in) So my three-fold question is: a) Is this a bad idea? b) Why is this a bad idea? c) What would you do instead?

  • Bad idea to force creation of Mercurial remote heads (ie. branches)?

    - by Chad Johnson
    I am developing a centralized web application, and I have a centralized Mercurial repository. Locally I created a branch in my repository hg branch my_branch I then made some changes and committed. Then when I try to push, I get abort: push creates new remote branch 'my_branch'! (did you forget to merge? use push -f to force) I've just been using push -f. Is this bad? I WANT multiple branches in my central, remote repository, as I want to 1) back up my work and 2) allow other developers to develop with me on that branch. Is it bad or something to have branches in my remote repository or something? Should I not be doing push -f (and if not, what should I do?)? Why does Joel say this in his tutorial: Occasionally I've made a change in a branch, pushed, switched to another branch, and changes I had made in that branch I switch to were mysteriously reverted to a previous version from several commits ago. Maybe this is a symptom of forcing a push?

  • Airport Express chokes Wi-Fi for a few seconds, several times per hour. Any idea why?

    - by user13727
    I'm using a MacBookPro connected to an AiportExpress' Wi-FI network. Every once in a while, the Wi-Fi will choke up and either drop some packets, or lag horribly for several seconds. I'm losing hair over this because every time I chat on Skype, the call hangs randomly due to this problem. Any idea what's wrong? Some more details: two networks are set up: 2.4Ghz and 5Ghz, and the issue happens on both the network uses WPA2 Personal for security the Airport is in the same room with my computer the Airport is fairly new, bought this summer, model number off the back: A1392 tried connecting to a neighbours wifi to see if it's a problem with my computer, or interference. It's not, it doesn't happen on their network. tried resetting it several times tried changing channels manually Ping results are below, so you can see what I'm talking about.

  • A big flat text file or a HTML site for language documentation?

    - by Bad Sector
    A project of mine is a small embeddable Tcl-like scripting language, LIL. While i'm mostly making it for my own use, i think it is interesting enough for others to use, so i want it to have a nice (but not very "wordy") documentation. So far i'm using a single flat readme.txt file. It explains the language's syntax, features, standard functions, how to use the C API, etc. Also it is easy to scan and read in almost every environment out there, from basic text-only terminals to full-fledged high-end graphical desktop environments. However, while i tried to keep things nicely formatted (as much as this is possible in plain text), i still think that being a big (and growing) wall of text, it isn't as easy on the eyes as it could be. Also i feel that sometimes i'm not writing as much as i want in order to avoid expanding the text too much. So i thought i could use another project of mine, QuHelp, which is basically a help site generator for sites like this one with a sidebar that provides a tree of topics/subtopics and offline full text search. With this i can use HTML to format the documentation and if i use QuHelp for some other project that uses LIL, i can import LIL's documentation as part of the other project's documentation. However converting the existing documentation to QuHelp/HTML isn't a small task, especially when it comes to functions (i'll need to put more detail on them than what currently exists in the readme.txt file). Also it loses the wide range of availability that it currently has (even if QuHelp's generated code degrades gracefully down to console-only web browsers, plain text is readable from everywhere, including from popular editors such as Vim and Emacs - i had someone once telling me that he likes LIL's documentation because it is readable without leaving his editor). So, my question is simply this: should i keep the documentation as it is now in the form of a single readme.txt file or should i convert it to something like the site i mentioned above? There is also the option to do both, but i'm not sure if i'll be able to always keep them in sync or if it is worth the effort. After asking around in IRC i've got mixed answers: some liked the wide availability of the single text file, others said that it is looks as bad as a man page (personally i don't mind that - i can read man pages just fine - but other people might have issues reading them). What do you think?

  • bad pool header 0x00000019 in windows 7 home premium when connecting to net followed by BSOD.

    - by shankar
    Hi, I am have random blue screen errors with an error code of bad pool header 0x00000019 whenever I try going online. I use a usb datacard/modem but when I try logging in using a regular dsl/broadband connection, I have the same issue. I had searched the query in windows knowledge base which said it is an issue with windows 7 and have provided a hot fix which they do not gaurentee. My vendor says something is wrong with my ram and has ordered for a new set of ram, but in my opinion if it was a ram related issue, the crashes should have occured even while playing games which are supposed to be ram intensive...If you need the mini dumps I can provide you the same..Kindly revert back..

  • bad printer isolation on print server or better way?

    - by Joseph
    I have noticed that when a printer or driver screws up on a Windows server it usually locks up or kills the print spooler and everyone can't print until it is fixed. Usually we have to put the troublesome printer on another server so when it fails, it doesn't take the whole group with it. That is assuming we ever figure out which printer is the problem. Is there a way to have it so that one bad apple doesn't ruin the bunch? Even if it is another form of printer serving, that would work as long as it's not hard for the user to find a printer and install drivers.

  • How can I diagnose a "502 Bad Gateway" response from an Apache/Tomcat configuration?

    - by Structure
    I just finished up configuring a fairly default configuration of Tomcat. My Apache configuration was pre-existing and post-tomcat it still has no issues. I am using mod_jk to (if I am saying this correctly) interface between Apache and Tomcat and have my conf files setup for my workers, etc. I put my test file (Simply: http://tomcat.apache.org/tomcat-4.1-doc/appdev/sample/web/hello.jsp) into my tomcat/webapps/ directory and then call it via http://localhost/test/hello.jsp. From here Apache returns a "502 Bad Gateway" response. I confirmed this via the Apache logs, but beyond that I have no idea how to diagnose the issue. I assume the 502 is because Tomcat did not respond. I'd like to confirm if Tomcat received the request, but cannot locate the log file. At this point I had thought my installation was complete, so not sure where to go from here. Any input would be appreciated.

  • Is it bad practice to extend the MongoEngine User document?

    - by Soviut
    I'm integrating MongoDB using MongoEngine. It provides auth and session support that a standard pymongo setup would lack. In regular django auth, it's considered bad practice to extend the User model since there's no guarantee it will be used correctly everywhere. Is this the case with mongoengine.django.auth? If it is considered bad practice, what is the best way to attach a separate user profile? Django has mechanisms for specifying an AUTH_PROFILE_MODULE. Is this supported in MongoEngine as well, or should I be manually doing the lookup?
