  • Code Review tools - to use or not?

    - by liortal
    On my dev team, we're doing code reviews, however not in a proper way i believe. The issues our process suffers from: Not enough time is allocated for proper code review. Doing reviews is not mandatory - many times it is simply not done. Devs sit together for reviews, due to lack of another easy mechanism for doing it "offline" without spending both developers' time. My question is: can integration of a tool for code reviews improve the points mentioned above? Is it not needed? I would love to hear from positive/negative experiences.

  • Programmaticaly finding the Landau notation (Big O or Theta notation) of an algorithm?

    - by Julien L
    I'm used to search for the Landau (Big O, Theta...) notation of my algorithms by hand to make sure they are as optimized as they can be, but when the functions are getting really big and complex, it's taking way too much time to do it by hand. it's also prone to human errors. I spent some time on Codility (coding/algo exercises), and noticed they will give you the Landau notation for your submitted solution (both in Time and Memory usage). I was wondering how they do that... How would you do it? Is there another way besides Lexical Analysis or parsing of the code? PS: This question concerns mainly PHP and or JavaScript, but I'm opened to any language and theory.

  • How to find domain registrar and DNS hosting with good DNSSEC support?

    - by rsp
    Simplified problem I want to buy a domain and make a website that is fully secured with DNSSEC. Background I've been hearing about the insecurity of DNS for years. I've watched all of the talks by Dan Kaminsky and others from DNS exploits to The future of DNS Security Panel. I knew that using DNS without security is a disaster waiting to happen. I followed the development of the DNSSEC standard. I celebrated the key signing ceremony. Everything was on the right track to finally have a secure DNS system in place. And now more than 2 years later I wanted to just do what everyone said I should do: use DNSSEC for a new domain. So I need a domain registrar and a DNS hosting service that supports DNSSEC. Surprisingly it is not that easy to even find out who does support DNSSEC. It was actually much easier to find info on DNSSEC two years ago when everyone was going to support DNSSEC Real Soon Now but now years passed and I hardly see any progress done. I just hope that I was just looking in the wrong places and someone here will explain all of the doubts. I hope that other people who want to have a secure website will also find this question useful. What is needed registrar and DNS servers with full DNSSEC support for .com domains What is not needed IPv6 support Web hosting anything more What I found out so far Go Daddy offers Premium DNS service for additional $36 per year that lets you "Secure up to 5 domains with DNSSEC". easyDNS has DNSSEC available in Beta across all service levels (you need to enable the "beta" flag in configuration) but it doesn't seem to be production ready and judging from the lack of updates it isn't a feature of highest priority (the last update from March 2011 on the easyDNS blog). Name.com - according to The Register (US domain registrar does IPv6, DNSSEC) it has DNSSEC support since 2010 but right now (October 2012) I couldn't find anything related to DNSSEC on their website. Dynadot that is very often recommended doesn't support DNSSEC Namecheap that is also often recommended doesn't support DNSSEC. The support answer from 2011 suggested that it was being added but in 2012 still no ETA is given to customers. DynDNS was supposed to support DNSSEC, I found a link explaining DNSSEC support but it gives 404 Not Found page and offers a search box - when searching for DNSSEC I get "No results were found for your query." GKG was recommended online for DNSSEC support but it's hard to find any information on the level of DNSSEC support - there is a brief explanation on what is DNSSEC and how to sign Delegation Signer records in their FAQ but no information about the level of actual support can be found. Ask Slashdot: Which Registrars Support DNSSEC? from July 2011 - Answers list Go Daddy, DynDNS, GKG, Name.com as registrars that support DNSSEC but: see above. Related questions How to find web hosting that meets my requirements? What is needed to add DNSSEC to my site? DNS hosting better managed by Domain provider or Hosting provider? Registrar with good security, DNS hosting, and DNSSEC and IPv6 resolvers? In no. 1 no one is ever mentioning DNS at all. In no. 2 answers only mention the .se TLD, there are very few answers and they seem very outdated. In no. 3 one answer says "On projects that demand higher security, I might look for a web host that supports DNSSEC" but no more information is provided. The only relevant answers are in no. 4 where easyDNS is recommended by someone who has never used them personally. Meanwhile, as of October 2012, the support of DNSSEC is described as "in beta" on the easyDNS feature list. Another one recommends SiteGround but searching their site for DNSSEC returns no results. Other answers recommend web hosting providers that don't meet the requirement of DNSSEC support. Also the question mentioned above lists 9 very specific requirements other than only DNSSEC (like eg. HTTP-only login cookies, two-factor authentications, no DNS record limits, DNS statistics of queries/day, audit trails etc.) which might have excluded many possible recommendations if one is only interested in DNSSEC support. Conclusions I thought that by the end of 2012 the support of DNSSEC among domain registrars and DNS providers would be nearly universal. I am shocked that the support seems virtually nonexistent. Is this a result of some serious problems with the DNSSEC adoption? Or is it just not a hot topic and no one bothers anymore? According to the DNSSEC Scoreboard roughly about 0.1% of .com domains support DNSSEC. Could that be caused by the lack of DNSSEC support among registrars and DNS providers, is the information too hard to find or maybe no one cares? There is even no "dnssec" tag here. Questions The information is surprisingly hard to find. That is why I am asking for first-hand experience and personal recommendations. Has anyone here actually set up a website with DNSSEC, from the domain registration to the configuration of DNS servers? Can anyone recommend any of the registrars mentioned above? Can anyone recommend any registrar not mentioned above?

  • mysql show databases not showing databases that are in /opt/bitnami/mysql/data directory

    - by hgolov
    and thank you for taking the time to look at my question. I have an ebs-backed ec2 ubuntu server which is running but unreachable. ** There are very stupidly no recent backups ** I made a snapshot of the block, created a volume, spun up a new instance, attached the new volume. I see all the data from my site in the /opt/bitnami/mysql/data directory, but when I go into the mysql console, it shows only information_schema and test when I type show databases; How can I 'point' mysql to the correct folder? Thank you!

  • Why isn't software as reliable as a car?

    - by Alex Angas
    I had a user ask me this question. We know that cars break down, but that's because of something physical (unless software is involved!). I tried to answer that software is a much younger industry, but the user countered with "didn't the automobile industry become much more stable than and reliable with less people?". I also tried to answer that software is more complex, but the user countered that there are many thousands of parts that make up a car. People that design and build cars generally just know their component(s) very well, but they still all end up working together as an end result. So, why isn't software as reliable as a car?

  • VirtualBox Ubuntu Server with DNS

    - by Boris Karl Schlein
    I just want to have a local server inside my VirtualBox that offers dns functionality like www.example.local = 127.0.0.1 . Host: Ubuntu 11.10, Guest: Ubuntu 10.10 On my server I can already ping www.example.local - so I configured my virtual host correctly. Question is, how can I address www.example.local from outside my VirtualBox? I searched Google and askubuntu and found dnsmasq. I installed dnsmasq on my server and followed all steps on help.ubuntu. On my host system I've set 192.168.178.91 to the list of dns servers (192.168.178.91 is the IP address of my local server which uses a bridged network adapter). Thing is, I still cannot ping (or connect to) my example.local virtual host. It gives me an unknown host response. How can I set up my DNS server correctly?

  • SQL SERVER – Find Weekend and Weekdays from Datetime in SQL Server 2012

    - by pinaldave
    Yesterday we had very first SQL Bangalore User Group meeting and I was asked following question right after the session. “How do we know if today is a weekend or weekday using SQL Server Functions?” Well, I assume most of us are using SQL Server 2012 so I will suggest following solution. I am using SQL Server 2012′s CHOOSE function. It is SELECT GETDATE() Today, DATENAME(dw, GETDATE()) DayofWeek, CHOOSE(DATEPART(dw, GETDATE()), 'WEEKEND','Weekday', 'Weekday','Weekday','Weekday','Weekday','WEEKEND') WorkDay GO You can use the choose function on table as well. Here is the quick example of the same. USE AdventureWorks2012 GO SELECT A.ModifiedDate, DATENAME(dw, A.ModifiedDate) DayofWeek, CHOOSE(DATEPART(dw, A.ModifiedDate), 'WEEKEND','Weekday', 'Weekday','Weekday','Weekday','Weekday','WEEKEND') WorkDay FROM [Person].[Address] A GO If you are using an earlier version of the SQL Server you can use a CASE statement instead of CHOOSE function. Please read my earlier article which discusses CHOOSE function and CASE statements. Logical Function – CHOOSE() – A Quick Introduction Reference:  Pinal Dave (http://blog.SQLAuthority.com) Filed under: PostADay, SQL, SQL Authority, SQL DateTime, SQL Function, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

  • Why was Mr. Scott Scottish?

    - by iamjames
    It's a good question:  of all the engineers in the world, why choose a Scottish engineer?  The Gene Roddenberry probably chose a Scottish engineer because of this guy: That's James Watt, the same guy the unit of energy watt is named after.  He was a Scottish inventor and mechancial engineer who built the first made significant improvements to the steam engine.  Made sense in the 60's, however given the past hundred years if they were to make a new Star Trek they might have started with a German engineer (or maybe Japanese), but since World War II had ended barely 20 years earlier the 20-somethings that had survived the war were now 40-somethings and seeing a German engineer probably wouldn't have gone over too well.

  • Java PlayFramework & Python Django GAE

    - by Maik Klein
    I already know Java, C# and C++. Now I want to start with web development and I saw that some really big sites are built with Python/C++. I like the coding style of Python, it looks really clean, but some other things like no errors before runtime is really strange. However, I don't know what I should learn now. I started with Python but then I saw that Google App Engine also supports Java and the PlayFramework looks amazing too. Now I am really confused. Should I go with Python or Java? I found the IDE for Python "PyCharm" really amazing for web development. Does Java have something similar, eclipse maybe? I know that this question isn't constructive, but it will help me with my decision. What are pro and cons of both languages?

  • rsnapshot intervals in configuration file…

    - by Patrick
    A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

  • Why should I consider using the Source Engine?

    - by dukeofgaming
    I've always been a Valve fan, but now that I have the opportuninty to choose a game engine for a project I'm not sure I want to choose the Source Engine after watching this wikipedia entry. My options essentially boiled down to an open source stack (Horde3D + Zoidcom + Spark + SFML + CEGUI, and well, not OSS but PhysX too), UDK and the Source Engine. My question is (because I really have no experience with it) why should any developer choose the Source Engine over any other open source or commercial option?, is the Source Engine really worth it as a game development tool or has it time already passed and it is obsolete against other solutions?. Thanks

  • I've filed an ITP bug on bugs.debian.org - now how do I get the package into Ubuntu?

    - by George Edison
    I've written a development library that I would like to include in the Ubuntu archives. From what I understand, the best way to do this is to first get the package into Debian and then request a package sync. Here is the ITP bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=691467 Now my question is simply... what do I do now? Looking at this page, I see horrifying things like "419 days in preparation" and "last activity 404 days ago". I get the impression that getting a package into Debian is a slow process. Is there anything I can do to speed up the process? I've tried to do as much work as I can to smooth out the process - I've got a branch with Debian packaging (which gets by Lintian without any errors).

  • Wireless driver - how to load manufacturer's STA file (Ralink 3290)

    - by Matt
    Caution: I'm a newb. Hardware: Giada i35G, cedar trail atom with nvidia gf119, railtek ethernet and Ralink 3290 for wireless. Already accomplished: Installed Ubuntu 12.10, loaded GPU drivers and redirected sound out through GPU card to HDMI. Ethernet works like a charm. Issue: Can't get my wireless up and running. There seems to be no package to which I can simply run a sudo get-aspt install ... I found the corresponding Linux driver from the manufacturer's site, but I have not managed to find out what to with the file. Here's the manufacturers site: http://www.ralinktech.com/en/04_support/support.php?sn=501 I get a file with the following name: \2012_0508_RT3290_Linux_STA_v2.6.0.0.bz2 I hope somebody might be able to tell me what to do next. Thanks for reading and apologies for potentially asking a trivial question. Best regards, Matt

  • Silverlight Grid Layout is pain

    - by brainbox
     I think one of the biggest mistake of Silverlight and WPF is its Grid layout.Imagine you have a data form with 2 columns and 5 rows. You need to place new row after the first one. As a result you need to rewrite Grid.Rows and Grid.Columns in all rows belows. But the worst thing of such approach is that it is static. So you need predefine all your rows and columns. As a result creating of simple dynamic datagrid or dataform become impossible... So the question if why best practices of HTML and Adobe Flex were dropped????If anybody have tried to port Flex Grid layout to silverlight please mail me or drop a comment.

  • quick approach to migrate classic asp project to asp.net

    - by Buzz
    Recently we got a requirement for converting a classic asp project to asp.net. This one is really a very old project created around 2002/2003. It consists of around 50 asp pages. I found very little documentation for this project, FSD and design documents for only a few modules. Just giving a quick look into this project my head start to hurt. It is really a mess. I checked the records and found none of the developers who worked on this project work for the company anymore. My real pain is that this is an urgent requirement and I have to provide an estimated deadline to my supervisor. I found a similar question classic-asp-to-asp-net, but I need some more insight on how to convert this classic asp project to asp.net in the quickest possible way.

  • World Record Batch Rate on Oracle JD Edwards Consolidated Workload with SPARC T4-2

    - by Brian
    Oracle produced a World Record batch throughput for single system results on Oracle's JD Edwards EnterpriseOne Day-in-the-Life benchmark using Oracle's SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2. The workload includes both online and batch workload. The SPARC T4-2 server delivered a result of 8,000 online users while concurrently executing a mix of JD Edwards EnterpriseOne Long and Short batch processes at 95.5 UBEs/min (Universal Batch Engines per minute). In order to obtain this record benchmark result, the JD Edwards EnterpriseOne, Oracle WebLogic and Oracle Database 11g Release 2 servers were executed each in separate Oracle Solaris Containers which enabled optimal system resources distribution and performance together with scalable and manageable virtualization. One SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2 utilized only 55% of the available CPU power. The Oracle DB server in a Shared Server configuration allows for optimized CPU resource utilization and significant memory savings on the SPARC T4-2 server without sacrificing performance. This configuration with SPARC T4-2 server has achieved 33% more Users/core, 47% more UBEs/min and 78% more Users/rack unit than the IBM Power 770 server. The SPARC T4-2 server with 2 processors ran the JD Edwards "Day-in-the-Life" benchmark and supported 8,000 concurrent online users while concurrently executing mixed batch workloads at 95.5 UBEs per minute. The IBM Power 770 server with twice as many processors supported only 12,000 concurrent online users while concurrently executing mixed batch workloads at only 65 UBEs per minute. This benchmark demonstrates more than 2x cost savings by consolidating the complete solution in a single SPARC T4-2 server compared to earlier published results of 10,000 users and 67 UBEs per minute on two SPARC T4-2 and SPARC T4-1. The Oracle DB server used mirrored (RAID 1) volumes for the database providing high availability for the data without impacting performance. Performance Landscape JD Edwards EnterpriseOne Day in the Life (DIL) Benchmark Consolidated Online with Batch Workload System Rack Units BatchRate(UBEs/m) Online Users Users /Units Users /Core Version SPARC T4-2 (2 x SPARC T4, 2.85 GHz) 3 95.5 8,000 2,667 500 9.0.2 IBM Power 770 (4 x POWER7, 3.3 GHz, 32 cores) 8 65 12,000 1,500 375 9.0.2 Batch Rate (UBEs/m) — Batch transaction rate in UBEs per minute Configuration Summary Hardware Configuration: 1 x SPARC T4-2 server with 2 x SPARC T4 processors, 2.85 GHz 256 GB memory 4 x 300 GB 10K RPM SAS internal disk 2 x 300 GB internal SSD 2 x Sun Storage F5100 Flash Arrays Software Configuration: Oracle Solaris 10 Oracle Solaris Containers JD Edwards EnterpriseOne 9.0.2 JD Edwards EnterpriseOne Tools (8.98.4.2) Oracle WebLogic Server 11g (10.3.4) Oracle HTTP Server 11g Oracle Database 11g Release 2 (11.2.0.1) Benchmark Description JD Edwards EnterpriseOne is an integrated applications suite of Enterprise Resource Planning (ERP) software. Oracle offers 70 JD Edwards EnterpriseOne application modules to support a diverse set of business operations. Oracle's Day in the Life (DIL) kit is a suite of scripts that exercises most common transactions of JD Edwards EnterpriseOne applications, including business processes such as payroll, sales order, purchase order, work order, and manufacturing processes, such as ship confirmation. These are labeled by industry acronyms such as SCM, CRM, HCM, SRM and FMS. The kit's scripts execute transactions typical of a mid-sized manufacturing company. The workload consists of online transactions and the UBE – Universal Business Engine workload of 61 short and 4 long UBEs. LoadRunner runs the DIL workload, collects the user’s transactions response times and reports the key metric of Combined Weighted Average Transaction Response time. The UBE processes workload runs from the JD Enterprise Application server. Oracle's UBE processes come as three flavors: Short UBEs < 1 minute engage in Business Report and Summary Analysis, Mid UBEs > 1 minute create a large report of Account, Balance, and Full Address, Long UBEs > 2 minutes simulate Payroll, Sales Order, night only jobs. The UBE workload generates large numbers of PDF files reports and log files. The UBE Queues are categorized as the QBATCHD, a single threaded queue for large and medium UBEs, and the QPROCESS queue for short UBEs run concurrently. Oracle's UBE process performance metric is Number of Maximum Concurrent UBE processes at transaction rate, UBEs/minute. Key Points and Best Practices Two JD Edwards EnterpriseOne Application Servers, two Oracle WebLogic Servers 11g Release 1 coupled with two Oracle Web Tier HTTP server instances and one Oracle Database 11g Release 2 database on a single SPARC T4-2 server were hosted in separate Oracle Solaris Containers bound to four processor sets to demonstrate consolidation of multiple applications, web servers and the database with best resource utilizations. Interrupt fencing was configured on all Oracle Solaris Containers to channel the interrupts to processors other than the processor sets used for the JD Edwards Application server, Oracle WebLogic servers and the database server. A Oracle WebLogic vertical cluster was configured on each WebServer Container with twelve managed instances each to load balance users' requests and to provide the infrastructure that enables scaling to high number of users with ease of deployment and high availability. The database log writer was run in the real time RT class and bound to a processor set. The database redo logs were configured on the raw disk partitions. The Oracle Solaris Container running the Enterprise Application server completed 61 Short UBEs, 4 Long UBEs concurrently as the mixed size batch workload. The mixed size UBEs ran concurrently from the Enterprise Application server with the 8,000 online users driven by the LoadRunner.

  • Sharing code in LGPL and proprietary software

    - by Martin
    Hi I'm working on a piece of software that'll be released as a dll under LGPL. The software interfaces with hardware from a small company that has provided me with the needed libraries and some code to use them correctly (not only headers but its all in a separate file). As far as i know, the same code is used in their proprietary software that they don't intend to open source but they'd be fine releasing the piece of code they've given me. Now here's the question: What license could be used on the code I got from the company? I guess using GPL or LGPL would make them violate GPL when using the same code in their other software. Is MIT a good idea? Is it ok to just include a file with MIT license on it in my otherwise LGPL:ed project? Since I'm not the copyright holder, I'd have to ask the company to apply the license obviously but that shouldn't be a problem. Thanks /Martin

  • SEO effect of “You are leaving this site” page for outbound links?

    - by Timo Huovinen
    The problem I am working on an aggregation website that collects reviews about specific products from various websites. The site has many thousands of outbound links (with "nofollow" attributes) to the content source websites where the reviews were collected from. The site has far more outbound links than inbound links and I have read that this is bad for SEO. The question Would adding an intermediate «You are leaving this site» disclaimer/warning page like this hurt search engine rankings? And can you provide any links about this topic? p.s. The exit page would be a POST form instead of a script, that notifies the user that he/she is leaving this site and provides a button to continue to the other website. p.p.s This kind of idea is implemented on many forums, aggregation websites with the purpose of warning the user that he/she is leaving this site and to block search engine bots from following those links because search bots do not submit forms.

  • Specifying a file name for the FTP and File based transports in OSB

    - by [email protected]
    A common question I receive is how to incorporate a variable value into a file name when using the FTP, SFTP, or File transports in Oracle Service Bus.  For example, if one of the fields in a message being put down to a file by the File transport is an order number variable, then how can you make the order number become part of the file name?  Another example might be if you want to specify the date in the file name.  The transport configuration wizard in OSB does not have an option to allow for this, other than allowing you to specify a static prefix of suffix variable.

  • Application for taking pretty screenshots (like OS X does)

    - by Oli
    I've been building a website for a guy who uses Mac OS X and occasionally he sends me screenshots of bugs. They come out looking like this: This is fairly typical of Mac screenshots. You get the window decorations, the shadow from the window and a white or transparent background (not the desktop wallpaper -- I've checked). Compare this to an Ubuntu window-shot (Alt+Print screen): It's impossible to keep a straight face and say the Ubuntu one anywhere near as elegant. My question is: Is there an application that can do this in Ubuntu? Edit: Follow up: Is there an application that can do this in one move? Shutter is pretty good but running the plugin for every screenshot is pretty tiresome as it doesn't seem to remember my preference (I want south-shadow and that requires selecting south, then clicking refresh, then save) and it's more clicks than I'd like. Is there a simple way of telling shutter I want south-shadow for all screenshots (except entire desktop and area-selection)?

  • Copyright notices/disclaimers in source files

    - by mojuba
    It's a common practice to place copyright notices, various legal disclaimers and sometimes even full license agreements in each source file of an open-source project. Is this really necessary for a (1) open-source project and (2) closed-source project? What are you trying to achieve or prevent by putting these notices in source files? I understand it's a legal question and I doubt we can get a fully competent answer here at programmers.SO (it's for programmers, isn't it?) What would also be interesting to hear is, when you put legal stuff in your source files, is it because "everyone does it" or you got legal advice? What was the reasoning?

  • Weekend reading: Microsoft/Oracle and SkyDrive based code-editor

    - by jamiet
    A couple of news item caught my eye this weekend that I think are worthy of comment. Microsoft/Oracle partnership to be announced tomorrow (24/06/2013) According to many news site Microsoft and Oracle are about to announce a partnership (Oracle set for major Microsoft, Salesforce, Netsuite partnerships) and they all seem to be assuming that it will be something to do with “the cloud”. I wouldn’t disagree with that assessment, Microsoft are heavily pushing Azure and Oracle seem (to me anyway) to be rather lagging behind in the cloud game. More specifically folks seem to be assuming that Oracle’s forthcoming 12c database release will be offered on Azure. I did a bit of reading about Oracle 12c and one of its key pillars appears to be that it supports multi-tenant topologies and multi-tenancy is a common usage scenario for databases in the cloud. I’m left wondering then, if Microsoft are willing to push a rival’s multi-tenant solution what is happening to its own cloud-based multi-tenant offering – SQL Azure Federations. We haven’t heard anything about federations for what now seems to be a long time and moreover the main Program Manager behind the technology, Cihan Biyikoglu, recently left Microsoft to join Twitter. Furthermore, a Principle Architect for SQL Server, Conor Cunningham, recently presented the opening keynote at SQLBits 11 where he talked about multi-tenant solutions on SQL Azure and not once did he mention federations. All in all I don’t have a warm fuzzy feeling about the future of SQL Azure Federations so I hope that that question gets asked at some point following the Microsoft/Oracle announcement. Text Editor on SkyDrive with coding-specific features Liveside.net got a bit of a scoop this weekend with the news (Exclusive: SkyDrive.com to get web-based text file editing features) that Microsoft’s consumer-facing file storage service is going to get a new feature – a web-based code editor. Here’s Liveside’s screenshot: I’ve long had a passing interest in online code editors, indeed back in December 2009 I wondered out loud on this blog site: I started to wonder when the development tools that we use would also become cloud-based. After all, if we’re using cloud-based services does it not make sense to have cloud-based tools that work with them? I think it does. Project Houston Since then the world has moved on. Cloud 9 IDE (https://c9.io/) have blazed a trail in the fledgling world of online code editors and I have been wondering when Microsoft were going to start playing catch-up. I had no doubt that an online code editor was in Microsoft’s future; its an obvious future direction, why would I want to have to download and install a bloated text editor (which, arguably, is exactly what Visual Studio amounts to) and have to continually update it when I can simply open a web browser and have ready access to all of my code from wherever I am. There are signs that Microsoft is already making moves in this direction, after all the URL for their new offering Team Foundation Service doesn’t mention TFS at all – my own personalised URL for Team Foundation Service is http://jamiet.visualstudio.com – using “Visual Studio” as the domain name for a service that isn’t strictly speaking part of Visual Studio leads me to think that there’s a much bigger play here and that one day http://visualstudio.com will house an online code editor. With that in mind then I find Liveside’s revelation rather intriguing, why would a code editing tool show up in Skydrive? Perhaps SkyDrive is going to get integrated more tightly into TFS, I’m very interested to see where this goes. The larger question playing on my mind though is whether an online code editor from Microsoft will support SQL Server developers. I have opined before (see The SQL developer gap) about the shoddy treatment that SQL Server developers have to experience from Microsoft and I haven’t seen any change in Microsoft’s attitude in the three and a half years since I wrote that post. I’m constantly bewildered by the lack of investment in SQL Server developer productivity compared to the riches that are lavished upon our appdev brethren. When you consider that SQL Server is Microsoft’s third biggest revenue stream it is, frankly, rather insulting. SSDT was a step in the right direction but the hushed noises I hear coming out of Microsoft of late in regard to SSDT don’t bode fantastically well for its future. So, will an online code editor from Microsoft support T-SQL development? I have to assume not given the paucity of investment on us lowly SQL Server developers over the last few years, but I live in hope! Your thoughts in the comments section please. I would be very interested in reading them. @Jamiet

  • What's a nice explanation for recursion?

    - by Gulshan
    This question is inspired by What's a nice explanation for pointers? So, what can be a nice explanation of the recursion? Update: The idea of recursion is not very common in real world. So, it seems a bit confusing to the novice programmers. Though, I guess, they become used to the concept gradually. So, what can be a nice explanation for them to grasp the idea easily? I expected some detailed answers. N.B. : Even I am going to post one answer. But to be fair, it will be few hours later.
