• Question about network topology and routing performance

  - by algorithms

  Hello I am currently working on a uni project about routing protocols and network performance, one of the criteria i was going to test under was to see what effect lan topology has, ie workstations arranged in mesh, star, ring etc, but i am having doubts as to whether that would have any affect on the routing performance thus would be useless to do, rather i'm thinking it would be better to test under the topology of the routers themselves, ie routers arranged in either star, mesh ring etc. I would appreciate some feedback on this as I am rather confused. Thank You

• Good infrastructure design questions for software developers?

  - by JakeRobinson

  Building on Jeff's blog post titled Vampires (Programmers) versus Werewolves (Sysadmins) From my perspective, the whole point of the company is to talk about what we're doing. Getting things done is important, of course, but we have to stop occasionally to write up what we're doing, how we're doing it, and why we're even doing it in the first place -- including all our doubts and misgivings and concerns. So, what are some questions you ask your software developers when they request a server?

• How important is sender validation, and what matters?

  - by Charles Stewart

  When I started learning how to configure email, SPF existed but there were doubts about whether it was a good thing, and the value of offering SPF records in DNS. Now it seems that it is widely accepted that some form of well-known sender validation is good practice. Is this really true? Am I being a bad postmaster by not supporting SPF/DKIM/whatever?

• Rules for setting hostname [duplicate]

  - by Ilia Rostovtsev

  This question already has an answer here: Hostnames - What are they all about? 5 answers Setting the hostname: FQDN or short name? 6 answers It's thought that for the hostname should be used FQDN. I have a doubts about whether using: host.domain.ltd and domain.ltd for the hostname is the same thing and will be equally correct / acceptable? I'm willing to use domain.ltd for the hostname. Is it alright?

• What server setup for a small web development company? [closed]

  - by Giordano

  I co-own a company with a friend of mine and we have decided to buy a new server to support our business (our current server is an Asus EEE Box, working great but too limited :) ). I should mention that we are web developers but occasionally we do small-office sys admin. Thus, 99% of time we work on GNU/Linux (mainly Ubuntu) but from time to time we need to setup a Windows environment to assist some customers (e.g. setup a temporary SQL Server 2008). Our requirements: Low budget: we don't want the cheapest solution out there but we can't afford to spend too much. Budget could be ~1000-1500€ (before VAT) Robustness: we would like to setup a RAID array and maybe have an external disk where we can store backups Virtualization: we need to be able to setup few servers for development. The scenario is something like this (~8 appliances running in parallel): Redmine + GIT server Bacula server FTP server 3-4 virtual appliances that could be set up on demand to test our applications or support a customer. The appliances could be: LAMP, Tomcat+PostgreSQL, SQL Server Support: if something breaks down it shouldn't be too difficult to find a replacement. Now, given the main requirements, there are some doubts we need to clarify: Do you suggest to buy a prepackaged solution (for example a customized Dell PowerEdge T110 or T310) or to assemble the server by ourselves (buy the separate components)? What RAID configuration do you suggest? I was thinking of RAID1 (probably cheaper) or RAID5. should we buy a hardware RAID controller or is it ok to use a software RAID (mdadm)? In case, which controller do you suggest? What processor do you suggest (Intel Xeon, i3, i5, i7, AMD)? How much RAM? (I was thinking at least 8GB, ~1GB per appliance) What virtualization software do you recommend? VMWare seems to be the best choice, but what about XEN or KVM? We don't want to buy licenses at the moment so we would like to consider only free options. What OS do you recommend? We know Ubuntu, Debian, Gentoo very well (we would like to use Ubuntu Server), however it seems a lot of people goes for CentOS. Thanks in advance if you can help us with this! It's our first "serious" server so many doubts popped up :) Please feel free to add further recommendations if you have some to share ;) Have a nice day

• What are the pros and cons of Coffeescript?

  - by Philip

  Of course one big pro is the amount of syntactic sugar leading to shorter code in a lot of cases. On http://jashkenas.github.com/coffee-script/ there are impressive examples. On the other hand I have doubts that these examples represent code of complex real world applications. In my code for instance I never add functions to bare objects but rather to their prototypes. Moreover the prototype feature is hidden from the user, suggesting classical OOP rather than idiomatic Javascript. The array comprehension example would look in my code probably like this: cubes = $.map(list, math.cube); // which is 8 characters less using jQuery...

• Will JVisualVM degrade application performance?

  - by rocky

  I have doubts in JVisual VM profiler tool related to performance. I have requirement to implement a JVM Monitoring tool for my enterpise java application. I have gone through some profiling tools in market but all them are having some kind of agent file which we need include in server startup. I have a fear that these client agent will degrade my application performance will more. So I have decided to JVisual VM because this profiler tool comes with JDK itself but before implementing JVisualVM, does anybody faces any issues with JVisualVM profiler tool? As well as, is this safe if I implement in application?

• Don’t Program by Fear, Question Everything

  - by João Angelo

  Perusing some code base I’ve recently came across with a code comment that I would like to share. It was something like this: class Animal { public Animal() { this.Id = Guid.NewGuid(); } public Guid Id { get; private set; } } class Cat : Animal { public Cat() : base() // Always call base since it's not always done automatically { } } Note: All class names were changed to protect the innocent. To clear any possible doubts the C# specification explicitly states that: If an instance constructor has no constructor initializer, a constructor initializer of the form base() is implicitly provided. Thus, an instance constructor declaration of the form C(...) {...} is exactly equivalent to C(...): base() {...} So in conclusion it’s clearly an incorrect comment but what I find alarming is how a comment like that gets into a code base and survives the test of time. Not to forget what it can do to someone who is making a jump from other technologies to C# and reads stuff like that.

• How to create scripts that create another scripts

  - by sfrj

  I am writing an script that needs to generate another script that will be used to shutdown an appserver... This is how my code looks like: echo "STEP 8: CREATE STOP SCRIPT" stopScriptContent="echo \"STOPING GLASSFISH PLEASE WAIT...\"\n cd glassfish4/bin\n chmod +x asadmin\n ./asadmin stop-domain\n #In order to work it is required that the original folder of glassfish don't contain already any #project, otherwise, there will be a conflict\n" ${stopScriptContent} > stop.sh chmod +x stop.sh But it is not being created correctly, this is how the output stop.sh looks like: "STOPING GLASSFISH PLEASE WAIT..."\n cd glassfish4/bin\n chmod +x asadmin\n ./asadmin stop-domain\n #In order to work it is required that the original folder of glassfish don't contain already any #project, otherwise, there will be a conflict\n As you see, lots of things are wrong: there is no echo command is taking the \n literaly so there is no new line My doubts are: What is the correct way of making an .sh script create another .sh script. What do you thing I am doing wrong?

• What is the correct way to install ATI Catalyst Video Drivers?

  - by Stephen Myall

  I am planning on doing a fresh install of 12.04 LTS and want to know what is the correct way to install ATI Catalyst Video Drivers in 12.04 LTS? In a previous AU question relating to 11.10 (here) NOT 12.04 the accepted response stated that ia32-libs was a dependency (even for 64bit machines). I studied other Q&A on AU and the reason for asking this specific question is that I wasn't sure about some of the dependencies needed. I was also receiving conflicting advice on other reputable websites which put doubts in my mind on what the correct approach was.

• What Are Some Advantages/Disadvantages of Using C over Assembly?

  - by Daniel

  I'm currently studying engineering in Telecommunications and Electronics and we have migrated from assembler to C in microprocessor programming. I have doubts that this is a good idea. What are some advantages and disadvantages of C compared to assembly? The advantages/disadvantages I see are: Advantages: I can tell that C syntax is a lot easier to learn than Assembler syntax. C is easier to use for making more complex programs. Learning C is somehow more productive than learning assembler cause there is more developing stuff around C than Assembler. Disadvantages: Assembler is a lower level programming language than C,so this makes it a good for programming directly to hardware. Is a lot more flexible alluding you to work with memory,interrupts,micro-registers,etc.

• Can I use Google Search to determine if my website contains original or copied content?

  - by Bas van Vught

  I have a few websites from customers that have (partially) the same content as other websites. I plan on rewriting all content that is not original, but how do I know if my websites have original content, or content that's been copied from another website? My customers say all the content is original, but I have my doubts to be honest. They often let other people who don't work there anymore write content for the sites. What I did so far is copy a line from my website that can be found in other websites as well and pasted it into Google Search. If my website is the first link, would it be considered the original source?

• Are RSS feeds used? [closed]

  - by acidzombie24

  I was thinking about implementing RSS feeds on my site. The one thing that came to mind is Are RSS feeds ever used?! I don't use them nor know anyone who does. I know to use them it must be through an rss feed program or built in with the browser. I like my browser clean and i know many ppl dont know how to use/configure their browser. So with my thoughts i deducted that rss are not used 99.9999% of people (thats 4 decimal places which is really saying something). Now twitter on the other hand or even email may be used. But I have doubts about rss feeds. Can anyone give me statistics or change my mind on implementing it? I suspect it would be simple but i dont think i should bother if no one will ever use it. I dont even use SE/SO RSS feeds.

• BDD: Getting started

  - by thom

  I'm starting with BDD and this is my story: Feature: Months and days to days In order to see months and days as days As a date conversion fan I need a webpage where users can enter days and months and convert them to days. I have some doubts ... Should I write my scenarios before coding anything or should I first write a scenario and then write code, write a scenario again and then write code, and so on ... ? If I should write my scenarios before, can my steps be approved and production code still does not get done? When should I do refactoring on my code? After the feature is done or after each scenario implementation?

• navigation menus and SEO

  - by Rodolfo

  I've always have my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• Need some help implementing VBO's with Frustum Culling

  - by Isracg

  i'm currently developing my first 3D game for a school project, the game world is completely inspired by minecraft (world completely made out of cubes). I'm currently seeking to improve the performance trying to implement vertex buffer objects but i'm stuck, i already have this methods implemented: Frustum culling, only drawing exposed faces and distance culling but i have the following doubts: I currently have about 2^24 cubes in my world, divided in 1024 chunks of 16*16*64 cubes, right now i'm doing immediate mode rendering, which works well with frustum culling, if i implement one VBO per chunk, do i have to update that VBO each time i move the camera (to update the frustum)? is there a performance hit with this? Can i dynamically change the size of each VBO? of do i have to make each one the biggest possible size (the chunk completely filled with objects)?. Would i have to keep each visited chunk in memory or could i efficiently remove that VBO and recreated it when needed?.
