Today I am Chinese

5 Comments

Google thinks I'm ChineseI’m going about my merry life and I use google every day.

Today Google decided I’m in China and redirects me to google.com.hk and it shows me all text in Chinese. It’s just another proof how silly it is trying to use the IP address to figure out location (or even worse trying to guess language based on IP address).

Click on the image to get it in its full glory.

I haven’t changed anything locally, but it seems Google has updated (broken) their database somehow.

Just to be perfectly sure my browser isn’t playing any tricks behind my back, I snooped up the headers sent in the HTTP request and there’s nothing notable:

GET /complete/search?output=firefox&client=firefox&hl=en-US&q=rockbox HTTP/1.1
Host: suggestqueries.google.com
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.13) Gecko/20101209 Fedora/3.6.13-1.fc13 Firefox/3.6.13

Luckily, I know about the URL “google.com/ncr” (No Country Redirect) so I can still use it, but not through my browser’s search box…

Fosdem 2011: my libcurl talk on video

1 Comment

Kai Engert was good enough to capture all the talks in the security devroom at Fosdem 2011, and while I’m seeding the full torrent I’ve made my own talk available as a direct download from here:

Fosdem 2011: security-room at 14:15 by Daniel Stenberg

The thing is about 107MB big, 640×480 resolution and is roughly 26 minutes playing time. WebM format.

I did a talk today at Fosdem with this title. The room only had 48 seats and it was completely packed with people standing everywhere it was possible around the seated guys.

The English slides from my talk are below. It was also recorded on video so I hope I’ll be able to post once it becomes available online

News flash! Tech terms used almost correctly!

6 Comments

Ok, The Social Network isn’t a new movie by any means at this time, but I happened to see it the other day. I’ll leave the entire story and whatever facts or not it did or didn’t portrait in a correct manner.

But I did spot the use of several at least basic technical terms used in the beginning that struck me as amazingly correctly used! The movie character Mark actually used wget to download images (at about 10:05 into the movie), and as you can see on my first screenshot the initial keystrokes we get to see on the command line also actually resembles a correct wget command line. You can click on these images to get a slightly larger version of the pics. I’m sorry I couldn’t get any higher quality ones, but I figure the point is still the same!

After having invoked wget, as is explained he gets many pictures downloaded and what do you know, the screen output actually looks like it could’ve been a wget that has downloaded a couple of files:

the-social-network-wget-output

He also mentioned the terms ‘Apache’, ’emacs’ and ‘perl scripts’ in complete and correct sentences.

Where is the world heading?!

Update: Hrvoje Niksic, the founder of wget, helped out with some additional observations:

The options looked right to me, something like -r -A.jpg …

I was wondering about the historical accuracy of the progress bar, but it checks out. The movie takes place about a year and a half after the release of Wget 1.8, which added the feature. The department that takes care of these things did a good job. 🙂

Cookies and Websockets and HTTP headers

So yesterday we held a little HTTP-related event in Stockholm, arranged by OWASP Sweden. We talked a bit about cookies, websockets and recent HTTP headers.

Below are all the slides from the presentations I, Martin Holst Swende and John Wilanders did. (The entire event was done in Swedish.)

Foss-sthlm number five!

In the series of Free Software and Open Source talks and seminars we’ve been doing in the Foss-sthlm community, we are about to set off the fifth meetup on February 24, 2011 in Kista, Stockholm, Sweden. This time we will offer six talks by six different persons, all skilled and well educated within their respective topics.

The event will be held completely in Swedish, and the talks that are planned to get presented are as following:

  1. Foss in developing nations – Pernilla NĂ€sfors
  2. Open Source Framework Agreements in the Swedish Government – Daniel Melin
  3. From telecommunications to computer networks – security for real-timecommunications over IP – Olle E Johansson
  4. Maintaining – how to manage your FOSS project – Daniel Stenberg (yes, that’s me)
  5. Peek in HTTP and HTTP traffic – Henrik Nordström
  6. Cease and desist, stories from threat mails received in the Rockbox project – Björn Stenberg

As usual, we do this admission free and our sponsor (CAG this time) will provide with something to eat and drink. After all the scheduled talks (around 20:00) we’ll continue the evening at a pub somewhere and discuss open source and free software over a beer or two.

See you there!

Rockbox on Maemo

Nokia-N900Thomas Jarosch has been quite busy and worked a lot on the Rockbox port for Maemo, it is the direct result of the previous work on making it possible to run Rockbox as an app on top of operating systems. It is still early and there are things missing, but it is approaching usable really fast it seems

The work on the app for Android has also been progressing over time and even though it is still not available to download from the Android Market, the apk is updated regularly and pretty functional.

Back in the printing game

HP Officejet 8500AAfter my printer died, I immediately ordered a new one online and not long afterwards I could pick it up from my local post office. As I use both the scanner and the printer features pretty much I went with another “all-in-one” model and I chose an HP model (again) basically because I’ve been happy with how my previous worked (before its death). “HP Officejet Pro 8500 A910” seems to be the whole name. And yeah, it really is as black as the picture here shows it.

This model is less “photo-focused” than my previous but I never print my own photos so that’s no loss. What did annoy me was however that this model uses 4 ink cartridges instead of the 6 in my previous, but of a completely different design so I can’t even re-use my half-full ink containers from the corpse!

My new printer has some fancy features. It is one of them that I can give an email address and then print on by sending email to it. The email address then gets a really long one with lots of seemingly random letters, it is in the hp.com domain and I can set up a white-list of people (From: addresses) that is allowed to print on it via email.

It also has full internet access itself so it could fetch a firmware upgrade file and install that entirely on its own without the use of a computer. (Which made me wonder if they use libcurl, but I realize there’s no way for me to tell and of course there are many alternatives they might use.)

Driver-wise, it seems like a completely different set for Windows (hopefully this won’t uninstall itself) and on Linux I could install it fine to print, but xsane just won’t find it to scan. I intend to instead try to use the printer’s web service for scanning, hopefully that will be roughly equivalent for my limited use – I mostly scan documents, bills and invoices for my work.

Going to FOSDEM 2011

1 Comment

Fosdem 2011We’re going to FOSDEM again. This year we’ll ship over the entire company (all three of us) and we’ll join up with a few fellow Rockbox hackers and spend a weekend in Brussels among thousands of fellow free software and open source hackers.

During this conference, 5-6 February, I’ve submitted a libcurl-related talk to the embedded-room that wasn’t accepted into the regular program, but I’ve agreed to still prepare it and I then might get a slot in case someone gets sick or something. A bit ungrateful as now I still have to prepare my slides for the talk but there’s a big risk that I’ve done it in vain! I’ve also submitted a suggestion for a second talk in the opensc/security room (also related to stuff in the curl project) but as of now (with but 16 days left) that schedule is yet to be announced so I don’t know if I’ll do a talk there or not.

So, I might do no talks. I might do two. I just don’t know. We’ll see.

If you’re a friend of mine and you’re going to FOSDEM this year, please let me know and we can meet and have a chat or whatever. I love getting faces to all the names, nicks and email addresses I otherwise only see of many people.

Update: My talk in the security room is titled “libcurl: Supporting seven SSL libraries and one SSH library” and will start at 14:15 on Saturday the 5th of February.

NASed and RAID1ed

Synology DS211jI finally got my act together and bought myself a Synology DS211j NAS  with two 2TB drives. I’ll use it as a shared network disk at home and I intend to backup to it – as I also have a home office it’ll feel better to be able to also backup company related data somewhat more safely. My previous backup was only copying data from one HDD to another within the same physical machine.

To make it slightly more resistant to disk and hardware errors I’ve configured the disks to do RAID1 (all data is stored on both disks simultaneously).

The GPLv2 license was provided printed on paper in the package.
