Open Source, Free Software, and similar
We’ve gotten a fair amount of questions on the libcurl mailing list about how to do the SSH-based protocols SCP and SFTP with libcurl on Windows, and here comes Andrei Jakab bursting in and provides us with this fancy PDF:
Using libcurl with SSH support in Visual Studio 2008
I’m convinced a user or two will find this a fine resource! Thanks Andrei!
From people in the open source community and then especially friends and fellow hackers in projects I am involved in, I sometimes get questions on how my open source participations affect my “real job”.
I work as a consultant during the days and I do contract development for hire. I’ve been a consultant since 1996 and during this time I’ve participated in more than 25 “full-time” projects for almost as many customers.
I contribute to numerous open source projects and I’ve done it for many years. I lead and maintain several open source projects. I’ve committed many thousands of times to public source code repositories.
Does the contributions make me more attractive to potential customers? Not particularly is my rather sad experience. While some of my customers notice my track record (my CV does of course mention my most notable contributions) most of my day-job clients focus solely on other paid projects I’ve done and that exact technologies and products I worked with and created in the past. It may of course not be too strange as things I do and get paid for is then potentially “good enough for someone to pay me for” while the stuff I do for free in open source projects are… well, not paid for and thus it can’t be qualified by that ruler.
Do I get new assigments thanks to my open source projects? Yes, I do, but usually they tend to be on the smallish side and not of the bigger kinds my regular assignments at work are.
And the reality is of course also that the vast vast vaaast majority of all software consultants that people hire to do development have no public record of open source involvement so it could just be a result of that this is so rare the customers never had a reason to learn or adapt to using open source contributions as a “factor”.
Or maybe I’m just ignorant and haven’t figured out how my customers truly work.
Do I work with open source in my day job? Yes almost exclusively. I’ve been working with Linux in various embedded systems basically the last 8 years and working with Linux systems pretty much implies a wide range of open source development tools as well.

There. Now please read this post again. It really isn’t. It never was, it never will be. It’s an entirely separate thing, an operating system written entirely from scratch with its own kernel and OS primitives.

I am a stats junkie so I like my stats in large amounts. But I like the stats to be right and as accurate as possible, and when I look at what ohloh produces I like the concepts and ideas in general, I just think their implementation is lacking in a few vital areas that need improvement:
1. There are no dependencies or hierarchies between packages, so “I use this” counters get worthless since people mark end-user packages they use. Low-level support packages and libraries that are used indirectly don’t get many “use counts”
2. Doing very few commits in a very well used project with few authors gives you way way more points than doing a bus-load of commits in something less used with many fellow contributors. This makes the top-list of people very skewed as some of the top-64 people only did a few hundred commits ever. I doubt many mortals would consider someone who only ever did 300 commits to be a top community person. At the very moment I write this, the #1 ranked person has done 20 commits during 5 months…!
3. Too few versioning systems are supported, leaving out huge chunks of the open source world. Bazaar, mercurial and a few more are a bit too popular to be ignored without the results getting skewed.
4. I’d like to see the “number of users” of products as a percentage, as the total number of users they show include all contributors to all projects. Out of the 140,000 users (which undoubtedly include a lot of duplicates), it would surprise me if more than 10,000 have actually registered what products they use. I’ve tried to find the exact number but I failed. So 3,000 users don’t mean 3,000 out of 140,000 but 3,000 out of 10,000…
I fell over this document named “What’s New in the Solaris 10 10/08 Release” and it includes this funny little quote towards the end:
C-URL – The C-URL Wrappers Library
C-URL is a utility library that provides programmatic access to the most common Internet protocols such as, HTTP, FTP, TFTP, SFTP, and TELNET. C-URL is also extensively used in various applications.
The project is cURL, the tool is curl and the library is libcurl. There’s nothing named C-URL and it isn’t any “wrappers library”… And the list of protocols is also funny since it includes 6 protocols while a modern libcurl supports 13 different ones, and also if you build libcurl to support SFTP you also get SCP (which the list doesn’t include) etc.
It just looks so very sloppy to me. But hey, what do I know?
I’ve mentioned some of my audio problems on my Linux desktop before, and just the other day a frie
nd suggested I should remove ‘esd’ (“apt-get remove esound”) as a means to fix one of my complaints and frequent annoyance (to get the sound working I had to kill esd first, then reload some drivers etc).
Recently my standard “trick” to get the sound brought to life had started to fail so I needed to get a new angle at this and boy, when I did a reboot now without esound installed my on-board sound works! And this without me doing any manual fiddling at all.
My motherboard’s sound info is displayed like this with lspci -v:

I held a 38 minute talk (in English) at the FSCONS conference 2007 about curl and libcurl, and now I’ve realized that the recording from that event is available online in various forms and ways.
You can get the pure Ogg Theora video files by using these links:
The slides from the presentation are still available.
fsfe.org hosts the complete collection of videos from that conference.
I haven’t yet had time and oppurtunity to watch it myself. I figure I’ll do that soon to see and learn from my own mistakes and odd habits when talking in public… and try to not get disturbed too much by my own accent!
If you’re into reading Swedish articles and want to see what I answered to questions asked by opensource.idg.se then go read the article.
They’re starting a series “HallÃ¥ där” (hello there), interviewing Swedish open source people about what they/we are up to etc and apparently I got to be first.
yassl is said to be Yet Another SSL library and I’ve been told that for example it is the preferred library used by the mysql camp. I got interested in this several years ago when I learned about it since I thought it was fun to see an alternative implementation of OpenSSL that still offers the same API.
Since then, I’ve amused myself by trying to build and run curl with it like every six months or so. I’ve made (lib)curl build fine with yassl (and its configure script also detects that it is an OpenSSL API emulated by yassl), but I’ve never seen it run the entire curl test suite through without failing at least one test!
I asked the mysql guy about how yassl has worked for them, but he kind of shrugged and admitted that they hadn’t tried it much (and then I don’t know really who he spoke for, the entire team or just he and his closest friends) but he said it worked for them.
Today I noticed the yassl version 1.9.6 that I downloaded, built and tried against curl. This time curl completely fails to build with it…
Let me also point out that it’s not like I’ve not told the yassl team (person?) about these problems in the past. I have, and there have been adjustments that have been meant to address problems I’ve seen. I just can’t make curl use it successfully… libcurl can still be built and run with OpenSSL, GnuTLS or NSS so it’s not like we lack SSL library alternatives.
The same team/person seems to behind another SSL lib called Cyassl that’s aimed for smaller footprint systems and I’ve heard whispers about people trying to get libcurl to build against that and it surely is going to be interesting to see where that leads!
