  • What are basic differences bettwen operating systems working as server? [closed]

    - by poz2k4444
    I'd like to know what are the differences bettwen differents operating systems working as server and what operating system is better using for an specific task like linux, unix, windows, solaris, novell, etcetera. It's not about a specific problem, it's just to know, for example, windows server works better with SQL Server, or Ruby with MacOS It's just I think some of us don't know what to choose when we have to use some specific technology

  • GNU Screen: one window per screen or one screen with multiple windows?

    - by yalestar
    I've inherited a few sys admin tasks recently and am trying to wrap my head around using screen. The way the previous guy left it, there are four screen sessions running, some of which have two or three windows running within. It doesn't appear that he was using any particular convention, so I ask you: Is it better to have each process in its own screen session, or better to group similar processes into a single screen? Or something different entirely?

  • grabbing/parsing iSCSI iface information

    - by chrisg
    I'm writing a puppet provider for iSCSI and want to grab information about the ifaces (in my case HBAs) we have, is there a better way than doing this: iscsiadm -m iface -I be2iscsi.00:00:00:00:00:00|grep iface.ipaddress|sed -e 's/iface.ipaddress = //' it looks pretty ugly, but the -n switch doesn't seem to work unless you're in --op=update is there a better way to grab this information, in particular in ruby?

  • Is there a way to make IE7 default to ms-image-mode:bicubic?

    - by Mark Ransom
    Internet Explorer 7 uses a rather crude method to resize images by default. There's a CSS tag img { -ms-interpolation-mode: bicubic; } to get better results, but I'm unable to change the source of the page. IE8 uses the better method as the default, but this is a corporate environment that is unable to upgrade at this moment. Is there anything in the options or a registry hack to change the default resizing mode in IE7?

    - by Hosni
    I have got a windows server 2003 with partitioned Hard drive 10Go and 80Go, and i want to improve the storage capacity as the little partition 10Go is almost full. So i have got choice between partition the hard drive to equal parts, or set up a new hard drive with better storage capacity.knowing that the server has to be on service as soon as possible. Which one may be the better solution that takes less time and less risks?

  • Memory Usage in LINUX

    - by Incredible
    I have a debian system. It has 8GB memory. When I do top it shows 7.9 GB memory used and rest free. I add up the memory usage of all the programs running from top and they hardly sum up to around 50 MB. So, where is rest of the memory being used? Can I have a better detailed info of the memory usage? What is a better way to check the memory usage?

  • i7 4770k or i7 4930k - Which for faster compile times? [on hold]

    - by Chumm
    I've looked up comparisons and found that single core performance seems to be better on i7 4770k, but has less cores that the i7 4930k. Would VS take advantage of extra cores when compiling, or would the difference be negible. I'm looking to buy the PC primarily for programming, so which would be better for visual studio? I already have the rest of my build ready, I just need to decide on this! :) thanks

  • Best way to set up servers for .NET performance

    - by msigman
    Assume we have 3 physical servers and let's say we are only interested in performance, and not reliability. Is it better to give each server a specific function or make them all duplicates and split the traffic between them? In other words dedicate 1 as DB server, 1 as web server, and 1 as reporting server/data warehouse, or better to put all three services on each server and use them as web farm?

  • Best password practices?

    - by sansenya
    for sensitive data, would it be better to have a somewhat long, but memorable password (and hence not totally random) or use a program like keepass to make a super long, random password with the highest possible entropy, and then just write down the password on a piece of paper kept in ones pocket. If that bang on the door comes, then swallow the paper. Which is a better security practice? I'm not in any way a criminal, i just am curious about topics concerning security. Thanks.

  • Java Concurrency: CAS vs Locking

    - by Hugo Walker
    Im currently reading the Book Java Concurrency in Practice. In the Chapter 15 they are speaking about the Nonblocking algorithms and the compare-and-swap (CAS) Method. It is written that the CAS perform much better than the Locking Methods. I want to ask the people which already worked with both of this concepts and would like to hear when you are preferring which of these concept? Is it really so much faster? Personally for me the usage of Locks is much clearer and easier to understand and maybe even better to maintain. (Please correct me if I am wrong). Should we really focus creating our concurrent code related on CAS than Locks to get a better performance boost or is sustainability a higher thing? I know there is maybe not a strict rule, when to use what. But I just would like to hear some opinions, experiences with the new concept of CAS.

  • Self Assessment Tests for Programmers

    - by THX1138.6
    I want to help the Dev team identify areas of knowledge (practical and theoretical) that they can work on. Though I am big believer in focusing on people's strengths being a good programmer requires (I think) being challenged by concepts and ideas that don't always come naturally. We work largely in the web app space using PHP & MySQL but better skills in data modelling, query optimisation, use of MVC and OOP etc. would help the team and the company a lot. I want to help the Dev team manage their careers, explore and expand their skills sets. Be all they can be and better than they were previously. I know its an idealistic goal but work must be about more than simply getting the work done. There should be some time to review, to learn, to grow and get better. Any thoughts, ideas, opinions and directions to tests or similar resources would be greatly appreciated.

  • Hashes vs Numeric id's

    - by Karan Bhangui
    When creating a web application that some how displays the display of a unique identifier for a recurring entity (videos on YouTube, or book section on a site like mine), would it be better to use a uniform length identifier like a hash or the unique key of the item in the database (1, 2, 3, etc). Besides revealing a little, what I think is immaterial, information about the internals of your app, why would using a hash be better than just using the unique id? In short: Which is better to use as a publicly displayed unique identifier - a hash value, or a unique key from the database? Edit: I'm opening up this question again because Dmitriy brought up the good point of not tying down the naming to db specific property. Will this sort of tie down prevent me from optimizing/normalizing the database in the future? The platform uses php/python with ISAM /w MySQL.

  • Best way for programmers to edit XAML

    - by JessicaB
    I was wondering how programmers chose to edit XAML. Most of the programmers I speak to seem to edit the raw XML, but that seems nuts to me since it is such a natural thing for a more visual editor (of course you often have to get down to the raw code ultimately, but isn't there a better way to lay out a grid, or edit a template, or add non c# triggers or manage commands? The one that really set me off was editing a menu -- Visual Studio 1.0 had a better menu editor for C++ than the raw XAML editing experience.) When I edit .aspx files I use a visual editor much of the time, and then for the raw stuff I get into the html code. I am aware of Expression Blend, but that seems far more focused on artistic types and GUI experts rather than programmers. Does anyone have recommendations for a better editor for XAML than VS? Especially so since VS seems to have real nasty problems with XAML editing too, like bugginess and poor performance? Appreciate your helping this XAML newbie.

  • What is the right approach when using STL container for median calculation?

    - by sharkin
    Let's say I need to retrieve the median from a sequence of 1000000 random numeric values. If using anything but STL::list, I have no (built-in) way to sort sequence for median calculation. If using STL::list, I can't randomly access values to retrieve middle (median) of sorted sequence. Is it better to implement sorting myself and go with e.g. STL::vector, or is it better to use STL::list and use STL::list::iterator to for-loop-walk to the median value? The latter seems less overheadish, but also feels more ugly.. Or are there more and better alternatives for me?

  • Working with images in WCF

    - by hgulyan
    Hi, I have a desktop application that needs to upload/download images to/from service computer over TCP Protocol. At first, I stored images in file system, but I need to in MS SQL DB to compare which solution is better. Number of images is over half a million. I don't know yet will there be any limitation on size of a photo. If you have done smth like that, please, write what your opinion upon this question. Which one is faster, more safe? Which of them works better with this number of photos? If I'll store on DB, do I need to store images apart from all other tables which I use for my application and which type works better - image or varbinary on DB?..and so on. Thank you.

  • What industries develop the highest quality software? Lowest quality? Why?

    - by Derek Mahar
    From your experience, of those industries that develop custom software for internal use such as financial services companies, which ones produce higher quality software measured in defect rates and, more qualitatively, ease of maintenance over the long term? What contributes the most to this achievement of higher quality? Is it due to better software development practices such as greater emphasis on testing or specification? Developers who better understand the tools or who are strong problem solvers? Better communication between team members? On the flip-side, which industries do you think produce the lowest quality software? Why?

  • Can someone recommend a resource/site/book to improve problem solving skills

    - by kjm
    I am a reasonably experienced developer (.NET, c#, asp.NET etc) but I'd like to hone my problem solving skills. I find that when I come up against a complex problem I sometimes implement a solution that I feel could have been better had I analyzed the problem in a different way. Ideally what I am looking for is a resource of some type that has 'practice problems and solutions' as I think my skills will only get better by practicing this more and adopting better practices. I hope my question is not to vague and I wont get upset with people answering with opinions etc.. thanks

  • Another Java vs. Scala perspective - is this typical?

    - by Alex R
    I have been reading about Scala for a while and even wrote some small programs to better understand some of the more exoteric features. Today I decided to do my first "real project", translating some 60 lines of ugly Java code to Scala to rewrite it using the better pattern-matching features (why? because the Java version was becoming hard to maintain due to excessive combination of regex and conditionals). About halfway through the editing process, Eclipse thew up this error: I get the general impression that the Scala IDE in Eclipse is a lot buggier and less complete than its Java equivalent. Is this correct or do I just have a bad installation? Is there a better IDE for Scala?

  • Which Javascript history back implementation is the best?

    - by Malcolm Frexner
    There are implementations for history.back in Micrososft AJAX and jQuery (http://www.asual.com/jquery/address/). I already have jQuery and asp.net ajax included in my project but I am not sure which implementation of history.back is better. Better for me is: Already used by some large projects Wide browser support Easy to implement Little footprint Does anybody know which one is better? EDIT: Another jquery plugin is http://plugins.jquery.com/project/history It is recommmended in the book JQuery Cookbook. This one worked well so far.

  • iPhone or Android for development?

    - by user974873
    I have programming experience and would like to start developing for mobile platforms. Now I see that iPhone and Android are both dominating he smartphone market, but also that more and more people are buying iPhones. Which one would be better to start developing for? I currently do not own a Mac but would purchase a Mac Mini if I was to buy an iPhone. Would it be better to buy iPhone and Mac because it will be better in the long run because of the amount of users or Android?

  • Migrating from Physical SQL (SQL2000) To VMWare machine (SQL2008) - Transferring Large DB

    - by alex
    We're in the middle of migrating from a windows & SQL 2000 box to a Virtualised Win & SQL 2k8 box The VMWare box is on a different site, with better hardware, connectivity etc... The old(current) physical machine is still in constant use - I've taken a backup of the DB on this machine, which is 21GB Transfering this to our virtual machine took around 7+ hours - which isn't ideal when we do the "actual" switchover. My question is - How should I handle the migration better? Could i set up our current machine to do log shipping to the VM machine to keep up to date? then, schedule down time out of hours to do the switch over? Is there a better way?
