• DSL vs Cable latency

  - by tovmeod

  currently I have a 10Mbps DSL line and I'm thinking to switch to a cable since they got 100Mbps for a little less than double the price I'm paying for 10Mbps. In other words the cable company is offering 100Mbps for the price of 20Mbps DSL. Since 10Mbps is more than enough for me I am worried about the latency, I saw this that is just a guy experiment, that shows that cable and DSL are the same in practical terms, and this but I couldn't grasp it, not sure if it is helpful. So my question is if there's any practical difference between cable and DSL, mainly in latency terms but I would be also interested in other advantages/disadvantages. This is for my home connection, I work from home but I don't run any server, I most of the time code, skype and eventually game.

• Does it make sense to write a build scripts in C++?

  - by Klaim

  I'm using CMake to generate my projects IDE/makefiles, but I still need to call custom "scripts" to manipulate my compiled files or even generate code. In previous projects I've been using Python and it was OK, but now I'm having serious trouble managing a lot of dependencies in two very big projects I'm working on so I want to minimize the dependencies everywhere. Someone suggested to me to use C++ to write my build scripts instead of adding a language dependency just for that. The projects themeselves already use C++ so there are several advantages that I can see: to build the whole project, only a C++ compiler and CMake would be necessary, nothing else (all the other dependencies are C or C++); C++ type safety (when using modern C++) makes everything easier to get "correct"; it's also the language I know the better so I'm more at ease with it even if I'm able to write some good Python code; potential gain in execution speed (but i don't think it will really be perceptible); However, I think there might be some drawbacks and I'm not sure of the real impact as I didn't try yet: might be longer to write the code (that said I'm not sure because I'm efficient enough in C++ to write something that work quickly, so maybe for this system it wouldn't be so long to write) (compilation time shouldn't be a problem for this case); I must assume that all the text files I'll read as input are in UTF-8, I'm not sure it can be easilly checked at runtime in C++ and the language will not check it for you; libraries in C++ are harder to manage than in scripting languages; I lack experience and forsight so maybe I'm missing advantages and drawbacks. So the question is: does it make sense to use C++ for this? do you have experiences to report and do you see advantages and disadvantages that might be important?

• Technology Choice for a Client Application [on hold]

  - by AK_

  Not sure this is the right place to ask... I'm involved in the development of a new system, and now we are passing the demos stage. We need to build a proper client application. The platform we care most about is Windows, for now at least, but we would love to support other platforms, as long as it's free :-). Or at least very cheap. We anticipate two kinds of users: Occasional, coming mostly from the web. Professional, who would probably require more features, and better performance, and probably would prefer to see a native client. Our server exposes two APIs: A SOAP API, WCF behind the scenes, that supports 100% of the functionality. A small and very fast UDP + Binary API, that duplicates some of the functionality and is intended for the sake of performance for certain real-time scenarios. Our team is mostly proficient in .Net, C#, C++ development, and rather familiar with Web development (HTML, JavaScript). We are probably intending to develop two clients (for both user profiles), a web app, and a native app. Architecturally, we would like to have as many common components as possible. We would like to have several layers: Communication, Client Model, Client Logic, shared by both of the clients. We would also like to be able to add features to both clients when only the actual UI is a dual cost, and the rest is shared. We are looking at several technologies: WPF + Silverlight, Pure HTML, Flash / Flex (AIR?), Java (JavaFx?), and we are considering poking at WinRT(or whatever the proper name is). The question is which technology would you recommend and why? And which advantages or disadvantages will it have regarding our requirements?

• Leveraging .Net 4.0 Framework Tools For Encrypting Web Configuration Sections

  - by Sam Abraham

  I would like to share a few points with regards to encrypting web configuration sections in .Net 4.0. This information is also applicable to .Net 3.5 and 2.0. Two methods can work perfectly for encrypting connection strings in a Web project configuration file:   1-Do It All Yourself! In this approach, helper functions for encrypting/decrypting configuration file content are implemented. Program would explicitly retrieve appropriate content from configuration file then decrypt it appropriately.  Disadvantages of this implementation would be the added overhead for maintaining the encryption/decryption code as well the burden of always ensuring sections are appropriately decrypted before use and encrypted appropriately whenever edited.   2- Leverage the .Net 4.0 Framework (The Way to go!) Fortunately, all needed tools for protecting configuration files are built-in to the .Net 2.0/3.5/4.0 versions with very little setup needed. To encrypt connection strings, one can use the ASP.Net IIS Registration Tool (Aspnet_regiis.exe). Note that a 64-bit version of the tool also exists under the Framework64 folder for 64-bit systems. The command we need to encrypt our web.config file connection strings is simply the following:   Aspnet_regiis –pe “connectionstrings” –app “/sampleApplication” –prov “RsaProtectedConfigurationProvider”   To later decrypt this configuration section:   Aspnet_regiis –pd “connectionstrings” –app “/SampleApplication”   The following is a brief description of the command line options used in the example above. Aspnet_regiis supports many more options which you can read about in the links provided for reference below.   Option Description -pe  Section name to encrypt -pd  Section name to decrypt -app  Web application name -prov  Encryption/Decryption provider   ASP.Net automatically decrypts the content of the Web.Config file at runtime so no programming changes are needed.   Another tool, aspnet_setreg.exe is to be used if certain configuration file sections pertinent to the .Net runtime are to be encrypted. For more information on when and how to use aspnet_setreg, please refer to the references below.   Hope this helps!   Some great references concerning the topic:   http://msdn.microsoft.com/en-us/library/ff650037.aspx http://msdn.microsoft.com/en-us/library/zhhddkxy.aspx http://msdn.microsoft.com/en-us/library/dtkwfdky.aspx http://msdn.microsoft.com/en-us/library/68ze1hb2.aspx

• Is it bad to put your computer in sleep mode every time? [closed]

  - by Ivo Flipse

  Possible Duplicate: What is the effect of always sleeping a laptop? Is it bad for batteries or something else? Often I have a lot of stuff open and don't feel like shutting down my laptop, so I just use sleep mode when I'm transferring it. But I have no idea if this might have any disadvantages. So my question is: is it bad to put your computer in sleep mode every time? Things I'm wondering: Should I turn off my computer every once in a while? Will continuous use of sleep mode slow down my system in any way? Are there any bad side effects (in the long term)? Any thoughts? FYI I'm using Windows 7 on a laptop

• Co-worker uses ridiculous commenting convention, how to cope? [closed]

  - by Jessica Friedman

  A co-worker in the small start-up I work at writes (C++) code like this: // some class class SomeClass { // c'tor SomeClass(); // d'tor ~SomeClass(); // some function void someFunction(int x, int y); }; // some function void SomeClass::someFunction(int x, int y) { // init worker m_worker.init(); // log LOG_DEBUG("Worker initialized"); // find current cache auto it = m_currentCache.find(); // flush if (it->flush() == false) { // return return false } // return return true } This is how he writes 100% of his code: a spacer line, a useless comment which says nothing other than what is plainly stated in the following statement, and the statement itself. This is absolutely driving me insane. A simple class written by him spans 3 times as much as it's supposed to, It looks well commented but the comments contain no new information. In fact the code is completely undocumented in any normal definition of "documentation". All of the comments are just a repetition of what is written in C++ in the following line. I've confronted him several times about it and each time he seems to understand what I am saying but then goes on to not change his coding and not fix old code which is written like this. I've went on and on again and again about the distinct disadvantages of writing code like this but nothing get through to him. Other co-workers doesn't seem to mind it as much and management doesn't seem to really care. What do I do? (sorry for the rant)

• Remote Working & Relocation

  - by James Burgess

  Sorry if this question is a duplicate, I did some extensive searching and found nothing on quite the same topic (though a couple on partially-overlapping topics). Recently, whilst on holiday in Munich, Germany, I was taken aback by the sheer number of programming-related posts available in the city that I easily qualify for (both in terms of knowledge, and experience). The advertised working environments seemed good and the pay seemed to be at least as good as what I'd expect here in the UK. Probably 80% of the advertisements I saw on the underground were for IT-related jobs, and a good 60% of those I was easily qualified for. At the moment, I work as a freelancer mostly on web and small software projects, but seeing the vast availability of jobs in Munich versus my local area has me thinking about remote working. I'm unable to relocate for a job for the next 3 years (my wife has a contract to continue being a doctor at her current hospital for that time) but would almost certainly be open to it after that (after all, my wife and I both love Munich). In the meanwhile, I would be very interested in remote-working. So, my question is thus do companies ever take on remote workers (even with semi-frequent trips to the office) from abroad, with a view to later relocation? And, if so, how do you go about broaching the topic with a recruiter when getting in contact about a job posting? Language isn't a barrier for me, here, as 90% of the jobs I've looked up in Munich don't require German speakers (seems they have a big recruiting market abroad). I'm also under no illusions about the disadvantages of remote working, but I'm more interested in the viability of the scenario rather than the intricacies (at least at this point). I'd really appreciate any contributions, especially from those who have experience with working in such a scenario!

• Server 2008R2 in Extra Small Windows Azure Instance?

  - by Shawn Eary

  Windows Azure hosting for an Extra Small (XS) Windows VM seems to come out to be about $10 a month right now. I think this XS instance gives you the equivalent of a 1 GHZ CPU with 768MB of RAM. I think the minimum requirements for Server 2008 is 1GHZ CPU with 512MB of RAM. Also, I think the minimum requirements for SQL Server Express is 1GHZ CPU with 256 MB of RAM and that the minimum requirements for Team Foundation Server Express 11 Beta is 2.2 GHZ CPU with 1 Gig of RAM (this 2.2 GHZ part could be a problem for my 1 GHZ XS VM...). Given the performance of the XS Azure instance, would I be able to install: a very basic MVC web site; a free instance of SQL Server Express; a free single user instance of Team Foundation Server Express 11 Beta and run the XS VM instance without serious crashing? I know there are other Shared WebHost providers that can provide these features for me, but those hosting providers have the following disadvantages: They sometimes cost a lot of money after all of the "addons" are in place They probably don't provide the level of security and employee integrity that Microsoft can provide They don't provide the total control that an Azure VM seems to provide

• SQL SERVER – Using RAND() in User Defined Functions (UDF)

  - by pinaldave

  Here is the question I received in email. “Pinal, I am writing a function where we need to generate random password. While writing T-SQL I faced following issue. Everytime I tried to use RAND() function in my User Defined Function I am getting following error: Msg 443, Level 16, State 1, Procedure RandFn, Line 7 Invalid use of a side-effecting operator ‘rand’ within a function. Here is the simplified T-SQL code of the function which I am using: CREATE FUNCTION RandFn() RETURNS INT AS BEGIN DECLARE @rndValue INT SET @rndValue = RAND() RETURN @rndValue END GO I must use UDF so is there any workaround to use RAND function in UDF.” Here is the workaround how RAND() can be used in UDF. The scope of the blog post is not to discuss the advantages or disadvantages of the function or random function here but just to show how RAND() function can be used in UDF. RAND() function is directly not allowed to use in the UDF so we have to find alternate way to use the same function. This can be achieved by creating a VIEW which is using RAND() function and use the same VIEW in the UDF. Here is the step by step instructions. Create a VIEW using RAND function. CREATE VIEW rndView AS SELECT RAND() rndResult GO Create a UDF using the same VIEW. CREATE FUNCTION RandFn() RETURNS DECIMAL(18,18) AS BEGIN DECLARE @rndValue DECIMAL(18,18) SELECT @rndValue = rndResult FROM rndView RETURN @rndValue END GO Now execute the UDF and it will just work fine and return random result. SELECT dbo.RandFn() GO In T-SQL world, I have noticed that there are more than one solution to every problem. Is there any better solution to this question? Please post that question as a comment and I will include it with due credit.

• Executing symbolic link to exe - "The specified path does not exist"

  - by basic6

  When trying to execute a symbolic link which points to an exe file (on Windows 7), the "Open with" windows appears. When renaming it to a ".exe" file, it says "The specified path does not exist. Check the path, and then try again.". Symlinks to other destinations seem to work fine. I know that because hard links are a reference to the file's inode, they do not have this issue. But because of their disadvantages (like replacing "target file" not possible), I avoid hard links. And Windows shortcuts (lnk files) aren't filesystem links. Although I haven't had any trouble with them yet, I'd rather avoid them as well. So is there any way to execute a symlink?

• Use CompiledQuery.Compile to improve LINQ to SQL performance

  - by Michael Freidgeim

  After reading DLinq (Linq to SQL) Performance and in particular Part 4  I had a few questions. If CompiledQuery.Compile gives so much benefits, why not to do it for all Linq To Sql queries? Is any essential disadvantages of compiling all select queries? What are conditions, when compiling makes whose performance, for how much percentage? World be good to have default on application config level or on DBML level to specify are all select queries to be compiled? And the same questions about Entity Framework CompiledQuery Class. However in comments I’ve found answer  of the author ricom 6 Jul 2007 3:08 AM Compiling the query makes it durable. There is no need for this, nor is there any desire, unless you intend to run that same query many times. SQL provides regular select statements, prepared select statements, and stored procedures for a reason.  Linq now has analogs. Also from 10 Tips to Improve your LINQ to SQL Application Performance   If you are using CompiledQuery make sure that you are using it more than once as it is more costly than normal querying for the first time. The resulting function coming as a CompiledQuery is an object, having the SQL statement and the delegate to apply it.  And your delegate has the ability to replace the variables (or parameters) in the resulting query. However I feel that many developers are not informed enough about benefits of Compile. I think that tools like FxCop and Resharper should check the queries  and suggest if compiling is recommended.

• Benefits of Server-side Coding

  There are numerous advantages to server scripting languages over client side languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripting are scripts that are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9 years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server-side scripts and JavaScript used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid. However, I would have to say that my personal experience would have to sway me in deciding what type of languages to use for form validation because they both have advantages and disadvantages based on the each situation.

• What are the benefits of running a app server in user space, like Unicorn, as opposed to as sudo?

  - by dan

  I've been using Phusion Passenger + Rails/Sinatra for a lot of projects. Passenger runs under the main Nginx or Apache process. But I'm interested in Unicorn, partly because it runs in user space. You just set up Nginx to proxy_pass requests to a unix socket that is connected to Unicorn processes that you fire up under a normal user account. Is there anything to be said as far as advantages and disadvantages of these two alternative approaches to running an web app? I mean in terms of ease of administration, stability, simplicity, etc.

• What conventions or frameworks exist for MVVM in Perl?

  - by Will Sheppard

  We're using Catalyst to render lots of webforms in what will become a large application. I don't like the way all the form data is confusingly into a big hash in the Controller, before being passed to the template. It seems jumbled up and messy for the template. I'm sure there are real disadvantages that I haven't described properly... Are there? One solution is to just decide on a convention for the hash, e.g.: { defaults => { type => ['a', 'b', 'c'] }, input => { type => 'a' }, output => { message => "2 widgets found of type a", widgets => [ 'foo', 'bar' ] } } Another way is to store the page/form data as attributes in a class (a ViewModel?), and pass a whole object to the template, which it could use like this: <p class="message">[% model.message %]<p> [% FOREACH widget IN model.widgets %] Which way is more flexible for large applications? Are there any other solutions or existing Catalyst-compatible frameworks?

• Graph data structures and journal format for mini-IDE

  - by matec

  Background: I am writing a small/partial IDE. Code is internally converted/parsed into a graph data structure (for fast navigation, syntax-check etc). Functionality to undo/redo (also between sessions) and restoring from crash is implemented by writing to and reading from journal. The journal records modifications to the graph (not to the source). Question: I am hoping for advice on a decision on data-structures and journal format. For the graph I see two possible versions: g-a Graph edges are implemented in the way that one node stores references to other nodes via memory address g-b Every node has an ID. There is an ID-to-memory-address map. Graph uses IDs (instead of addresses) to connect nodes. Moving along an edge from one node to another each time requires lookup in ID-to-address map. And also for the journal: j-a There is a current node (like current working directory in a shell + file-system setting). The journal contains entries like "create new node and connect to current", "connect first child of current node" (relative IDs) j-b Journal uses absolute IDs, e.g. "delete edge 7 - 5", "delete node 5" I could e.g. combine g-a with j-a or combine g-b with j-b. In principle also g-b and j-a should be possible. [My first/original attempt was g-a and a version of j-b that uses addresses, but that turned out to cause severe restrictions: nodes cannot change their addresses (or journal would have to keep track of it), and using journal between two sessions is a mess (or even impossible)] I wonder if variant a or variant b or a combination would be a good idea, what advantages and disadvantages they would have and especially if some variant might be causing troubles later.

• I have a server running Windows 2008 R2 Core and it needs to hosts either SVN or GIT

  - by Jason Adams

  The server allocated for our cross platform projects (both Mac & PC) source repository is running Win2008R2 Core. We're really happy with its stability and we aren't interested in moving over to non-core. We need to get either SVN or GIT installed on the aforementioned box in the shortest amount of steps. We know the advantages/disadvantages of both systems. That being said, we don't care which one we use, we're just are looking for the path of least resistance on setting up a repository on a machine running R2 core.

For this project want a very effective structure, which will be easily maintainable and have no compromise about performance issue. Below structures are now present in my old projects. Entity Layer BusinessLogic Layer. DataLogic Layer UI Layer. Bellow picture describe how they are internally connected. For my new project want to change my project structure, I want to follow below steps: Core Layer(common) BLL DAL Model UI Bellow picture describe how they are internally connected. Though goggling some initial type question’s are obscure to me, they are : For new project want to use Entity framework, is it a good idea? Will it increase my project performance? Will it more maintainable than previous structure? Entity Framework core disadvantages/benefits are? For my project need help to select best structure.

• How can I evaluate the best choice of archive format for compressing files?

  - by Mehrdad

  In general, I've observed the following: Linux-y files or tools use bzip2 or gzip for distributing archives Windows-y files or tools use ZIP for distributing archives Many people use 7-Zip for creating and distributing their own archives Questions: What are the advantages and disadvantages of these formats, all of which appear to be open formats? When/why should I choose one (say, 7-Zip) over another (say, ZIP)? Why does the trend above appear to hold, even though all of these are portable formats? Are there any particular advantages to using a particular archive format on a particular platform?

• What did Rich Hickey mean when he said, "All that specificity [of interfaces/classes/types] kills your reuse!"

  - by GlenPeterson

  In Rich Hickey's thought-provoking goto conference keynote "The Value of Values" at 29 minutes he's talking about the overhead of a language like Java and makes a statement like, "All those interfaces kill your reuse." What does he mean? Is that true? In my search for answers, I have run across: The Principle of Least Knowledge AKA The Law of Demeter which encourages airtight API interfaces. Wikipedia also lists some disadvantages. Kevlin Henney's Imperial Clothing Crisis which argues that use, not reuse is the appropriate goal. Jack Diederich's "Stop Writing Classes" talk which argues against over-engineering in general. Clearly, anything written badly enough will be useless. But how would the interface of a well-written API prevent that code from being used? There are examples throughout history of something made for one purpose being used more for something else. But in the software world, if you use something for a purpose it wasn't intended for, it usually breaks. I'm looking for one good example of a good interface preventing a legitimate but unintended use of some code. Does that exist? I can't picture it.

• One vs. many domain user accounts in a server farm

  - by mjustin

  We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

• Is Zabbix the right tool for me?

  - by hortitude

  I just want to monitor a small handful of servers (less than 10). From reading various places it sounds like the top leading contenders (for open source at least) are: nagios munin zabbix From what I have read a lot of people tend to use munin and nagios together -- munin for history and graphs, and nagios for alerting. On the other hand it sounds like Zabbix is a more complete solution and easier to configure than either of the other two. So I was thinking of going that route. My thoughts right now are: What are the general disadvantages of Zabbix? Does Zabbix have a small footprint on boxes it is monitoring? Do I really need to setup an entire other server for it? I currently have a server that is under very light load -- can I dual purpose it?

• Business Forces: SOA Adoption

  The only constant in today’s business environment is change. Businesses that continuously foresee change and adapt quickly will gain market share and increased growth. In our ever growing global business environment change is driven by data in regards to collecting, maintaining, verifying and distributing data.  Companies today are made and broken over data. Would anyone still use Google if they did not have one of the most accurate search indexes on the internet? No, because their value is in their data and the quality of their data. Due to the increasing focus on data, companies have been adopting new methodologies for gaining more control over their data while attempting to reduce the costs of maintaining it. In addition, companies are also trying to reduce the time it takes to analyze data in regards to various market forces to foresee changes prior to them actually occurring.   Benefits of Adopting SOA Services can be maintained separately from other services and applications so that a change in one service will only affect itself and client services or applications. The advent of services allows for system functionality to be distributed across a network or multiple networks. The costs associated with maintain business functionality is much higher in standard application development over SOA due to the fact that one Services can be maintained and shared to other applications instead of multiple instances of business functionality being duplicated via hard coding in to several applications. When multiple applications use a single service for a specific business function then the all of the data being processed will be consistent in terms of quality and accuracy through the applications. Disadvantages of Adopting SOA Increased initial costs and timelines are associated with SOA due to the fact that services need to be created as well as applications need to be modified to call the services In order for an SOA project to be successful the project must obtain company and management support in order to gain the proper exposure, funding, and attention. If SOA is new to a company they must also support the proper training in order for the project to be designed, and implemented correctly. References: Tews, R. (2007).

• Mozilla Thunderbird 3.1.9 - not compatible with GMail conversation view addon?

  - by user69991

  A lot of time I already spent to find a suitable plugin (or addon) for mozilla thunderbird gmail conversation view. I found this : https://addons.mozilla.org/af/thunderbird/addon/gmail-conversation-view/ but it is just not compatible with my thunder bird version.. what I need to solve is: if one of my friends sends an email to me and another 10 friends. and everyone write a response. I can not read all in one mail (one by one). But I have to open 10 new emails. and is very hard to look over all. so can I have it like in Gmail? Do I have to install older version? is this possible and what are disadvantages? Thanks in advance.
