What resources are available that use benchmarks for comparing programming languages?
I am interested in both
How quickly a program in a given language can execute a given benchmark?
How many lines of code are required in a given language to implement a given benchmark?
There is a long-standing web site called the Computer Language Benchmarks Game, originally created by Doug Bagley as the "Great Computer Language Shootout". (You can view a little history at Portland Patterns Repository.)
Is anyone aware of other resources that enable programmers to compare performance and size of programs written in different languages?
Alternatives
After a quick google search, I found a couple other sites where benchmarks for various languages have been done. Some other sites mention the programming language shootout site that is currently down.
There is a CPAN module for Perl that uses the same code found on that site.
Google has a directory where pages on this topic can be found. I have not found any yet that are as comprehensive as the page you speak of, but there are certainly other resources out there for comparisons.
Archived / Cached Page
If you're only seeking some information there, you can view archived pages of the site using the Wayback Machine or Google's cached version. Try searching Google with "site: shootout.alioth.debian.org" and click on the "Cached" links for the pages you find.
Find the Author?
Perhaps the best option is to try to contact the owner of the old site and find out what happened. The author mentioned in the BSD licence on this page is "Brent Fulgham". He may or may not be the one to contact.
Wait until Alioth is Fixed
As #ioguy found out, Debian's Alioth server that hosts the site in question is currently under maintenance. I would suggest subscribing to the debian-devel-announce mailing list for updates, and an idea of when it may be fully functional again.
If you find problems in the future, you can probably post to the debian-user list.
Each year there are two or three
isolated blog posts that claim to
compare performance and size of one
or two programs written in different
languages.
As a resource the blog posts fail for obvious
reasons, most obviously:
not updated with newer versions of the language implementation
not updated with better programs
Every couple of years someone
dissatisfied with something about
the benchmarks game (often some
detail about the code repository or
website technology) starts a project that will
fix everything they dislike about the benchmarks game.
As a resource the most obvious problem with those
projects is that they never seem to get
close to publishing performance
data.
Every year some group of programmers
campaigns to have language X
included in the benchmarks game,
while some other group demands that
some program is included (or
excluded).
Sadly, they rarely accept that among
the resources provided by the
benchmarks game are
scripts they can use to make and publish language performance
measurements
examples of which basic information (language version, build
commands, run commands, measurement
techniques, ...) is required to provide context for the measurements.
They rarely accept that they are
empowered to create what they wish
to see.
The benchmarks game website is now back to normal!
From Friday 20 May 2011 through Monday 23 May 2011, ALL alioth.debian.org subdomains were down - because the alioth admins were upgrading "in every way we can find: kernel, Debian release, FusionForge software, hardware, and so on."
In addition, making the benchmarks game website work again required:
installation of the GD library on the new server, for chart generation
basic information about changes to ssh use on the new servers
basic information about the project cvs repository on the new servers
basic information about the project /htdocs location on the new servers
replacement of the long deprecated
$HTTP_GET_VARS by $_GET in a couple
of dozen PHP scripts
Since the performance benchmark site
for Programming Languages (aka
Programming Language "Shootout" &
shootout.alioth.debian.org) is
permanently down ...
The original question was predicated on a false premise.

I'm sitting here writing a function that I'm positive has been written before, somewhere on earth. It's just too common to have not been attempted, and I'm wondering why I can't just go to a website and search for a function that I can then copy and paste into my project in 2 seconds, instead of wasting my day reinventing the wheel.
Sure there are certain libraries you can use, but where do you find these libraries and when they are absent, is there a site like I'm describing?
Possibly a wiki of some type that contains free code that anybody can edit and improve?
Edit: I can code things fine, I just don't know HOW to do them. So for example, right now, I'm trying to localize a robot/car/point in space. I KNOW there is a way to do it, just based off of range and distance. Triangulation and Trilateration. How to code that is a different story. A site that could have psuedo code, step by step how to do that would be ridiculously helpful. It would also ensure the optimal solution since everybody can edit it. I'm also writing in Matlab, which I hate because it's quirky, adding to my desire for creating a website like I describe.
StackOverflow.com. No, I'm not joking.
At its best, people come here saying "hasn't some library done X already", and very often the Collective Wisdom answers "yes". But the biggest obstacle is lack of a description language: even here, a big problem for many posters is describing the problem clearly enough for others to recognize it as something they've seen before.
And if people can't understand what you're trying to do, no search engine will.
Firstly, two caveats:
Copy and pasting code you don't understand is a bad idea. Make sure you understand exactly what the code does before you use it.
Make sure you respect the license of the code you are copying. This is important!
Those caveats aside, it's often language dependent. Languages with an open development ethos (not just an open source implementation, think Python as compared to Java) tend to have official archives of open source libraries. For example:
Perl (which probably started this trend) has CPAN
Python has PyPI and Python Cookbook
PHP has PEAR
C++ has boost
Ruby has gems
R has CRAN.
Haskell has Hoogle and Hackage
Furthermore, don't forget to look in your languages standard library. Some modern languages have massive standard libraries, which have often contained the functionality I am looking for:
Java has its API documentation
C# and VB.NET have the massive MSDN
Non-openly developed languages often have non-official community archives. For example:
C# tends to have a lot of code at CodePlex and CodeProject
MATLAB has the Matlab Central File Exchange
A third category of sites are language agnostic. They are often best search through POG (plain old-fashioned Google). For example:
Stack Overflow
SourceForge
The confusingly language agnostic Java2s
Planet source code
Github
Finally, a fourth category of sites that I find increasingly useful are source-code search engines:
Google Codesearch
Koders
You may also be able to find useful source code, or at least get help writing something, through various pastebins.
Pastebin is language-agnostic
HPaste is mostly Haskell, but has a little in other languages.
Often, at the end of the day it is easiest just to google it, though.
There is a wiki that contains free code that anybody can edit and improve:
Rosetta Code.
As a means of an overview there is the "Solutions by Programming Task" page.
From the former page:
"Rosetta Code is a programming chrestomathy site. The
idea is to present solutions to the same task in as
many different languages as possible, to demonstrate
how languages are similar and different, and to aid a
person with a grounding in one approach to a problem
in learning another."
Cutting and pasting code you find on the Internet into production code would be like chewing gum found in the street. - Mike Johnson
With that in mind, try sites that host opensource projects like GitHub, CodePlex, code.google.com, etc.
I'm not sure this question is language agnostic, but I use GitHub this way ;) Other languages may have places where this is possible.
Safari Bookshelf from O'Reilly has many, many books that contain many implementations from which to choose.
http://my.safaribooksonline.com/
I was a subscriber for a few years before coming to my current job, where we have a corporate account! It's one of the best perks, and one of the best resources I have available. I haven't bought a computer book in years.
Aside from sites like this (Stack Overflow) I don't think there's many, maybe CodePlex, but I almost marked you -1 for assuming that code found on the Internet is yours to copy.
I'd suggest reading about software licencing, I hope you'd at least comment where you got it from.

What is a best way to organize many software development projects, interaction with clients, project documentation, sources, emails, knowledge, time tracking, issue and features tracking, support for releases and versions etc. for a small company?
For me (and I believe for many others) it is obvious that it must be some sort of web-based solutions. It would be great if it could provide an interface for iPhone (if not, it is also OK).
Important thing: it must be hosted on our servers, so PHP + MySQL is the best platform so far.
I have found the following system to consider:
http://www.activecollab.com/ (but I didn't found issue tracking as well as support for releases and versions, so it is not the best match for software development company)
http://www.mantisbt.org/ (Great tool, but no project planing...)
http://www.twproject.com/ (didn't try yet, but it has very strange interface)
But none of them is a 100% solution for me.
It also should (but not must) support SCRUM
We have about 25 people in our team and about 50 from client side. At once we run about 3-7 projects (some in dev. phase, some in support).
So, my questions: does anybody knows any good web-based system that gives everything software development company needs? I believe this information will be useful for many of us.
I would recommend FogBugz
They have a very interesting (admittedly not everyone's cup of tea) scheduling system and is apparently supporting scrum.
Their support for release management is something i'm particularly fond of, but i should also say that i have very little experience of other similar systems.
Another feature that I like is the ability to link different e-mail accounts as well as pure HTML forms to different projects.
Oh, and it is not a MySQL/PHP solution.
Some of the features are:
Issue tracking
Project planning
Scheduling
Customer support
Wiki

I think it really depends on your company size. I used activecollab for a while but it never really convinced me and then they made it commercial anyway. There is an open source fork of it called ProjectPier.
Even if it is not MySQL + PHP but Ruby On Rails Redmine convinced me the most from all tools I tried (and installing the ruby module into apache is a question of 5 minutes). It is simpel and yet has anything I need (including Eclipse Mylyn, SCM integration, E-Mail Notification and time tracking). With a little RoR knowledge it is easily customizable, too.
The most popular Open Source sollution is probably Trac. It is written in Python, so it is not a PHP either.
But maybe it makes sense to consider a non PHP sollution. I didn't find any PHP open source tool that had the functionality and simplicity of Redmine or Trac. If you don't mind a hosted sollution Basecamp is probably the first address to turn to (never tried it though).
Trac with Agilo plugin might be a good option.
Here is link for Trac pluigns, some category are:
Code Documentation
User feedback and discussions
For another pespective - having used many of the above solutions, and liking them very much for bug tracking, wiki documentation and tracking information - I tend to move towards keeping much of my project "meta-data" (summary information pulling together wiki, bugs, schedules, communication) in spreadsheets now.
For those now climbing onto the top rope of the ring preparing for a takedown, here's why... I come from a programming background, and one of the best books I read early in my career was The Pragmatic Programmer. One of the tenets they preach is finding a fundamental editor that you like, and get good with it (for various Very Good Reasons). After trying (frustratingly) to port and adapt my PM/Dev Management approach multiple times to multiple systems, I've extrapolated that Pragmatic tooling philosophy to the product/project management world I now inhabit. To stretch the metaphor, my editor is now Excel.
I can't guarantee that for any company I work with, they have "Software Project Management xyz" or "Bug Tracking System abc" with the proper plugins - but I can be darn well sure they have Excel or some variant available. I know if I get ninja-like with that tool, I can continue to use it - and focus on the project, not the tools.
This spreadsheet approach comes with some caveats:
Excel done poorly can suck. We've all seen that. Watch for bloat and stupidity.
Keep the bugs in the bug tracking system, the wiki stuff in the wiki. The spreadsheet is meant to pull this stuff together, not replace it.
Keep it readable. Don't stuff everything in just because you can. Summary sheets are good.
Try to standardize your templates and macros meaningfully for tasks and information, to maximize reuse over time and projects. Just like good programming.
Back it up - use a document management system if you can. This approach isn't in the cloud or hosted centrally by default, so be aware of that.
Have you tried Assembla? They've recently released a new product called Portfolio which is great if you have to manage multiple projects + you get free clients! :)
You might like to consider http://targetprocess.com/ We use that in my current job and it works pretty well, from a developer point of view. I'm unsure as to whether it supports your installation requirements, however.
I want to add a "Community" section (Bulletin Board) to my website so everyone can communicate, but I don't know what I'm doing.
How would I go about adding this and which one offers the most documentation and support?
Whatever you do, make certain that you read the instructions on configuring your discussion software to protect you and your community for the worst parts of the internet: spam, spoofing, and abuse.
Make certain that you immediately change the admin password from the one that comes with the installation.
If you leave your communities wide open to all kinds of posting, harvesting, and general mis-use, you'll spend your days playing whack-a-mole with thousands of idiots. Develop your acceptable use policy, configure your boards to support it, then enforce it.
And if the software you are looking at doesn't support things like e-mail verification, moderation, abuse reporting, anti-spamming controls, etc., just keep looking.
Be prepared to spend time managing your community so that it doesn't become another one of the millions of web forums out there full of off topic posts that drive people away from your website.
I think what you needed is a forum software, there are tones of free and open source ones available on the net. DotNetNuke is a .NET one but can be expensive to host and phpBB is another popular choice and there are a lot of cheap hosting solutions.
is your site based on php/mysql or asp/sql? Chances are if you do not know where to even find tables, that you are not able to what you actually want.
HOWEVER, if it's php/mysql, i recommend Cool Php Scripts book. It covers creating sort of a community forum/message board.
As i said again, you are probably not going to do it alone, at least, without a long frustrating learning curve.
You can always post a job and someone would be more than willing to bid on it at elance or rentacoder or any other site of your choice
Wikipedia has a big honking list of forum software. Pick the one that best matches the programming language(s) you're familiar with, the features you need, etc.
This is what you need.
Edit: They don't offer a hosted version there. You can use this instead. It's hosted on it's own site, free, and doesn't require a download.
I find Vanilla to be a much better forum application that phpBB for reasons of aesthetics as well as extensibility. I have not seen/used it in a situation where many sub-forums were required, so depending on your scope it may not be the right choice, but for small-to-medium sized forums I'd suggest trying it first.
First, you need to choose a forum software that matchs your requirements.
Then, just follow the Installation Guide provided by the software you have choosen.

I'm facing developing a new web app in the future and I'm wondering how to decide what framework to use. I've settled on Python as my language of choice. But there are still may frameworks to choose from! More generally how do you choose between different similar technologies that are still in the works as the latest round of web frameworks are? I'm curious what your process is for deciding on technologies you've never used.
Recognize that no choice is perfect -- or even very good.
No matter what you choose, someone will have a suggestion that -- they claim -- is better.
No matter what you choose, some part of your tech. stack will fail to live up to your expectations.
The most important thing is "shared nothing" so that the components can be replaced.
After that, the next most important thing is automatically-generated features to reduce or prevent programming.
Look at Django. Lots of automatic admin features make life very pleasant.
There are a number of things you can do:
Download the frameworks and build something similar with them for comparison.
Look for comparisons by other people, but attempt to understand the bias of the reviewer.
Observe the community at work, see what people are building and the issues they run into when using the technology. Forums, blogs, mailing list etc are good places to check out.
Go to conferences and meet like minded developers interested.
You can also take the approach of using stable versions rather than alpha bits. After a while you might move closer the bleeding edge. People associated with the project in question are generally more biased than those approaching from other platforms, be careful who you trust.
Consider the impact of using a bleeding edge framework versus an established one. Sometimes it's important to your customers that you are on one perceived as stable. At other times this doesn't matter. How comfortable are you with fixing the framework itself? Great developers will learn the internals, or at least know enough to keep things moving whilst a bug is sent to the framework mailing list etc.
Consider some general best practices in building abstractions and reusable code on the python platform. You may be able to save yourself some work in moving to another platform. However, don't be a reuse junkie as this can limit the effectiveness of your use of the framework. The 37Signals guys are right when they talk about extracting frameworks from working code rather than building frameworks from scratch.
I know this is an old posting, but I am in a similar situation (again) and I think there are other people who may want to look for different opinions, and hear of (somewhat) successful experiences.
Since baudtack mentioned Python, I will try to answer this along the lines of my experiences using Python. Here is what has been working for me:
determine the scope of your project - outlining what your application is supposed to be able to do without introducing any programming or design notes will clarify your goals greatly
determine how you would like to work with your code, stack and data:
a. what sort of programming paradigm do you want to work with? i.e. object-oriented, functional, etc. do you want to play to your programming style or do you want to follow somebody else's programming style?
b. use semantic web or not? do you want greater control over URIs and their design? (I found web.py great for this by the way - It is my choice to create REST APIs in Python)
c. do you want to be trapped by framework requirements, or do you want a better separation of the application from the web component, i.e. use a framework to utilize your application as a set of modules, for example. My problem with Django was that I ended up not programming Python, but having to learn more Django than I needed to. If that works for you, then that is the way to go.
d. data stores... some sort of SQL vs. non RDBMS (xml databases like eXist-db with full xquery support) vs. OODBMS vs. a combination of the above? how complicated do you need this to be? how much control/separation do you need to have over how data gets stored and recalled in your application?
e. testing: unit tests... thank goodness for python! if your web app has the potential to grow (as they often do), having a sane and coherent testing platform to begin with will help out a lot in the future - I wish I had learned about this earlier on. oh well... better late than never.
f. how much control over the server do you need? hosting considerations? how much control over an Apache instance do you need to have? OS specific needs? I found that using shared hosting providers like Webfaction has been great. I eventually found I needed greater needs for flexibility and bandwidth. In other words, what can you get for your budget? If you have USD50 to spend each month, it may be better to consider a virtual hosting solution like Linode....
Finally, I echo S.Lott's sentiments that no choice for a solution is perfect, and are subject to obsolescence.
Experience trumps hearsay. I've found that prototyping is a huge help. Make a prototype that uses the features you expect to be the most important for various frameworks. This helps route out any features that may not work "as advertised."
In general though, kudos for being willing to look at new technologies.
I have a set of criteria in different categories:
Activity & Documentation
Is there an active user base?
Is there an active development base?
Is the support responsive and information accessible?
Are there user and development guides and reference material?
These are essential, there needs to be traceability of all of these to build confidence in the solution.
Ease of use
Are basic features easy and complex features possible? I typically give a new framework a test drive and try to roll out a set of use cases to see how intuitive the framework is to use.
Is installation intuitive and simple for a local/dev installation and production deployment?
How is it backed up and upgraded?
What is the effort and UX for implementing a "Hello World" type blog post, static page, menu item, and plugin?
How are versions dealt with for the core & plugins?
Example (on the topic of Automated Testing/Continuous Integration solutions)
Several years ago I evaluated several Automated Testing solution. At the time Jenkins and TeamCity were front runners and in the end I chose TeamCity because of the UX, active user & development base and quality of accessible documentation.
Example (CMS for a blog)
This criteria is also why I prefer to use Wordpress over other options. While wordpress has its shortcomings, the user and development base is strong and active which leads to a software architecture with more potential to evolve over time and maintain its relevance and a development community that provides quality plugins and themes to choose from.

I have been looking for a collaborative tool for developing functional specifications. I am looking for the ability to:
Have multiple users contribute to the specification.
Provide some form of traceability, which could be done manually if needed.
Provide users with the ability to add comments and notes.
Upload and display Visio documents
Upload and display mockup screens using Balsamiq Mockup.
My initial impression is that using a wiki could be a good tool for this task. Does anyone have experience with using a wiki for creating functional specifications? What would be the pros and cons to using a tool like this as opposed to a requirements management tool?
Your input is greatly appreciated!
It's possible to do what you describe, to develop requirements in a collaborative way, in spite of using a wiki. Nothing about the wiki paradigm assists in this process.
I managed a wiki on the Zend Framework project to track proposals for components. They're still using it. Proposals are different from functional specifications, but the usage is similar enough to your question that I think this is relevant.
A wiki doesn't take care of itself. Unless you have someone responsible for managing it and making sure there is some structure and consistency, it quickly becomes a mess. The real-world analogy would be to hand each of your team a blank sheet of paper and tell them to write up their part of the requirements. Problems with this are:
Every contributor has to make up their own document structure, and write about different things in a different order. So it's impossible to compare one page to another.
There's no "index page" to organize all the disparate contributions. No one wants a page to "fall through the cracks," but in a wiki that's the default destiny of any page as soon as it's written.
There's no feedback loop to make sure the writing actually gets done.
The way to make it work is to apply some process to the project, and use the wiki in accordance with that process.
Give people the ability to create a new page in the wiki, but only through an interface that automatically links the new page into the right index.
Define a lifecycle for documents, so they are sure to be drafted, reviewed, and approved at the appropriate stages.
Provide a template for a new page. Provide the section headings that you need in each of these pages, and make part of the review process a confirmation that head section has been filled out adequately.
"What would be the pros and cons to using a tool like this as opposed to a requirements management tool?"
While it seems like a great idea, what you run into are people who can't and won't write.
People who can't write -- well -- can't write. They can't communicate with an email or a wiki or any medium outside voice.
Some people are "disorganized". Actually, writing is too linear and they don't think linearly.
Some people don't get the "write to your audience" and write stuff that's incomprehensible.
Sometimes you can't even figure out what they're talking about, much less what they're writing about. They talk in jargon or code. They don't know much but insist on being heard.
Some people won't write.
Some people refuse to make commitments. Even in a wiki where it can be retracted. They feel they must pre-discuss everything.
Some people are in the habit of doing everything by giving direction to someone else. They either don't write for themselves, or, they make people stand around in their office and listen to them talk and type.
Some people are generally toxic on any kind of project. They spring new requirements at the last minute. Their first response is "that will never work". They don't brainstorm well. When they say it work work, and you beg them for an improvement, they don't have one. They just know it won't work.
My experience is that only programmers can use a Wiki successfully. And only senior-level programmers.
N00bz don't have enough experience to sort out requirements from design from rumors and management fluff.
N00bz don't always have the language skills to write clearly. They may eventually, but one look at their Javadoc comments indicates that they're struggling with the "clarity" part of writing.
It's very appealing. I'm hoping for people to get better at using wiki's because I think it could have a lot of advantages over more traditional approaches where one person interviews everyone and writes things down. But it requires a level of confidence and skill in communication that few people seem to have.
Consider researching Fog Bugz. They tout themselves as the best of the
best for project management. Considering Joel's history I'd give them the
benefit of the doubt. They use a wiki in the way you've just described.
I would suggest signing up for the free trial, if you're serious.
Depending on the size of your project, buying it might be a very good
option.
At very least you could look at how they've structured it, or read the
forums for ideas on how to build your own stripped down version
Specialist tools help keep things on track and introduce a fixed work-flow. This is kind of the point, keeping things focused and functional. Using generic tools like a Wiki might be great for a bunch of programmers but introducing one for 'mixed-mode' work might be bad:
Things can creep and get off-track quickly
Communication can be lost in the medium
Look at things like Basecamp. They can be thought of as an applied wiki, or collaborative tool. A generic tool for specific purpose needs refining. I don't know if MediaWiki or others have enough customization to keep things clean and focused.
Maybe gather the requirements for your requirements management tool (recursive I know) and what aspects (communication aspects) you can take from the wiki culture and an open-communication mindset. If neither requirements management tools or wikis fit the bill, look at building one. Might be the next big thing. It feels like saying Could I use a wiki instead of Bugzilla?
A fixed work-flow webapp for requirements management with an open-communication emphasis that allows people from many roles to see and understand might be good!
We have used TWiki and now FosWiki in that context. There are many things one gets for free (version control, access control, Web-base access, searches, remote management, security patches, ...). In a few minutes, one can define:
a table defining requirements attributes,
which creates interactive forms with field selection and validation (where you can also document discussions and rationales, embed images, attach documents, link to other requirements...),
and then queries on these "requirements" and show them as tables that can be sorted, filtered, printed, reported against, etc. (e.g., http://jucmnav.softwareengineering.ca/ucm/bin/view/ProjetSEG/JUCMNavRequirementsVer2).
Obviously, one can easily use hyperlinks and Wiki links along the way. FosWiki also has features that can be used to enforce specific workflows, if needed. It is also easy to support forms for use cases and other paradigms (we have done this in the past, and that works generally well).
Wikis such as FosWiki are extensible and one could develop further modules for addressing weaknesses related to traceability management and impact analysis, table-based modifications of requirements, overall packaging, etc.
As a middle ground between a free-form wiki and a requirements management tool, consider using a structured wiki like Foswiki. I haven't done any formal requirements management (with a wiki or otherwise), but I have used TWiki (the predecessor to Foswiki) for other tasks, and it permits you to define a workflow, form fields, and so on as you need them, while keeping the flexibility of a wiki when you don't need a formal structure.
I agree with all (most) of the people above - use of a wiki may sound ok, but wiki's are meant to be present information and be updated as needed, not to be used as an interactive project management tool. I would strongly suggest SmartSheet (I'm a strong advocate of the product) - it provides a spreadsheet like interface where you can store multiple files per row/task, send out automated updates to users and maintain specification revisions...
The other approach could be the use of Google email, docs and calendar - a free friendly way of team interaction....I would shy away from issue/bug tracking tools for project management - they tend to have differ on focus: PM tools on the entire project/resource/timeline and Issue tracking tools for specific entered issues....
This may be a bit old now, but I am currently using Atlassian's "Confluence" and it's been great. I currently work as a UX engineer playing the role of "Product Owner" within an Agile process. I can document requirements for discrete interfaces, allow for multiple users' feedback and comments, and intertwine each interface with other interfaces within a larger context (e.g. user story). Everything is very dynamic and template driven. It's suiting my current needs very well.
