Back and Off Again

by Zef Hemel

A couple of days ago I got back from the south of the Netherlands, where I and a couple friends were camping. Photos can be found here.

Tomorrow morning I’m traveling to Latvia again. However, this time the travel won’t be as nasty as last time (at least, if everything goes well). I’m leaving around 7.45 in the morning and will arrive there at 21.35 local time the same day. So I don’t have to stay on the airport overnight this time (thank god).

Enjoy your holidays (if you got them).

Because I’m going to be away from my family and friends a lot in the next year (at least) I’ve set up another weblog (in Dutch) at Zef.Nu. There I’ll post personal stuff, stories and pictures. So if you’re interested and (think you) can read Dutch, feel free to visit Zef.Nu from time to time. I’ve even spent a little time to hack in a simple mailing list feature into my Wordpress installation over there so that you can receive an e-mail whenever I post a new article on Zef.Nu. All I have to do now is pray that no future employer ever gets to see the code.

My PC broke down again. It gives angry sounding beeps when I try to boot it. It has been doing this randomly for the past months. There’s something wrong with some piece of hardware, but I don’t know which, and to be frank, I don’t feel like finding out either. Therefore I’ve been working purely on my iBook the past two days. It’s a good way of getting used to it, because it will be my main computer while in Ireland.

I’ve been playing with some nice Mac software, notably NetNewsWire and MarsEdit. The first one is software that allows you to easily keep track of RSS/Atom feeds of news sites and weblogs. Previously I used BlogLines, but this client-side application is so much more user-friendly. It’s amazing how this application does exactly what you want it to do.

MoonEdit is an application that allows you to add, edit and remove weblogs posts on your weblog, including WordPress (what I use). This is much more convenient than editting in the browser. It even helps a little with inserting HTML and makes it really easy to upload files to your weblog and link to it from a post.

After playing both those these applications I decided to buy them (you get a discount when you buy them both).

I just finished my almost last assignment for my current university before the holidays and before I got to Trinity College. It’s an essay for the software architecture course I took. I thought I’d put it online for those interested. It’s not a masterpiece, but it should do for the credits I get for it (it’s only 30% of the grade).

In this essay, runtime quality attributes of distributed storage systems are discussed. These quality attributes are scalability, security, robustness and performance. For three different distributed storage systems (GoogleFS, DISP and Gnutella), the architecture and fulfilment of these quality attributes are looked at and evaluated.

New Camera and Flickr

by Zef Hemel

A week or so ago I bought my first own digital camera. It’s a “HP Photosmart R707″:http://www.shopping.hp.com/webapp/shopping/product_detail.do?storeName=storefronts&landing=storefronts&category=digital_cameras&subcat1=six_mp&catLevel=2&product_code=Q2232A%23ABA and so far I like it very much. It works perfectly with my iBook, which is important because that’s going to be my main computer for the next year in Ireland. This is what it looks like:

It comes with two batteries, so if one is empty I can put in the second. There’s also a dock that I can use to recharge both batteries simultaneously if I want. I can just put my camera on there and it can easily import the pictures and movies on my iBook. It works almost seamlessly. Did I say movies? Yes! The camera can record 320×200 MPEG movies for as long as it fits on the secure digital storage card (of which I bought a 512MB one). That means that I can record around 40 minutes long, with sound. Cool huh?

Since I came back from Latvia I have been looking for the best way to publish my pictures online. I tried the iPhoto (the photo application I use on my iBook) export function and that works, but it’s not ideal and quite basic. Yesterday I remember people being so happy with a service called “flickr”:http://www.flickr.com. If you’re Dutch you’re probably smiling now. Flickr in Dutch is pronounced in the same way as flikker, which is a term commonly used for homosexuals. But anyway, back to flickr. Flickr is a free service that allows you to upload as many pictures as you want to the internet for free. It allows you to easily organize them into sets, rotate them and do so other funky things, plus it allows you to tag your photos which make them searchable, also for other flickr users (if you want). The most important drawback of the free flickr is that you’re limited to uploading 20MB of pictures in a month which is not a lot. You can, however, upgrade your account for $24 per year which allows you to upload 2GB of pictures each month, which is enough for me. This “pro” service also allows you to create as much picture sets as you like. I upgraded my account and it’s working great for me.

If you want to publish your pictures online I can recommend having a good look at “flickr”:http://www.flickr.com

London Attacks

by Zef Hemel

You undoubtly heard all about this, but London has been attacked by terrorists. There are dozens of injuries. As of now 2 deaths confirmed, but at the very least 10 deaths at Kings cross. I recommed watching sites like “BBC News”:http://news.bbc.co.uk/ and “CNN”:http://www.cnn.com for the next hours.

It’s strange to see places where I’ve been many times blown up, with people running around. I had never been to New York or Madrid, having it happen in London (although it seems not as bad as in New York and Madrid) feels so much closer.

Why do these things have to happen?

Yesterday, at July 4th (yah, I know), YaBB turned 5 years old. I think it’s the second oldest free bulletin board software project alive today. I went to visit the “YaBB community forums”:http://www.yabbforum.com/community/YaBB.pl yesterday and it looked kinda dead. They even seemed to have forgotten their birthday themselves. There seem to be some releases from time to time, though. I think they’re working on releasing YaBB 2 now (would be about time too, since plans for YaBB 2 have started around 4.5 years ago).

But anyways, happy birthday YaBB :)

Latvian Tales, Part 3

by Zef Hemel

At saturday it’s time for me to see some Latvian sights. We go to a place that, if I remember correctly, is called Segunda. There they have caves with very old inscriptions:

Cave

Cave

Cave

Nearby we also walked around through the beautiful nature and forest. It was beautiful, but once again also hot and humid. Which means… mosquitos, mosquitos and above all: mosquitos. Aaargh. With bloody legs and arms, because of all the mosquitos that I killed, we left.

The next day we’re having brunch at 12.00 with Zanete’s friend Maija. Maija is having a bad day that day. While walking to the restaurant a car splashes through some water on the road. Maija’s the main victim. In the restaurant Maija only gets a cup of coffee because she already ate (she forgot all about the fact that we’d eat together). She walks to our table, sees an interesting-looking dog and wham! there goes her cup of coffee. After dinner Maija has to look something up on the internet. We decide to drive to her brother’s work where there’s a wireless access point that we can use. When we get there my and Zanete’s wireless internet work fine, but Maija’s doesn’t. Then we drive to the bus station to let Maija buy a ticket for the bus to Riga (where she lives, studies and works). As soon as she queues up, there’s a technical problem and we have to wait. After around 10 minutes I suggest to her to give the rest of the people in the line a break by getting out of the line. So that the technical problem gets resolved. She laughs, but doesn’t leave the line. Another 10 minutes later the problem is fixed and she can get her ticket.

Tuesday morning we get up at 5.00. Today I’m getting on the plane back to Holland. The bus to Riga leaves at 6.00. When we arrive in Riga at around 7.30, we have to walk about half an hour to the bus station to the airport. We get there at around 8.02, the bus just left. This shouldn’t be a problem, as Maija convinced Zanete that there are multiple busses leaving each hour. Not so. The next one leaves at 9.20, and I have to be checked-in before 9.35, considering that the ride to the airport takes approximately 30 minutes, this is not an option. What now? Zanete calls some people who tell her that at the place where we arrived in Riga there’s also a bus leaving to the airport. That’s just great. We walk/run back all the way, which isn’t a lot of fun with a big suitcase, even though it has wheels. When we arrive there we wait for bus 22. When the bus arrive and check if it goes to the airport, the driver tells us that we’re at the wrong side of the road… Just in time for the last bus to the airport at 8.30 we get to the other side of the road. We arrive at the airport at 9.10. Thank god there’s no long line and I can check in quickly.

The flight back to Berlin went fine, except for the landing which was sort-of roller-coaster like. When I get to the train station I have to get back to the Zoologische garten station. But this time I know how to buy the ticket! I think… I immediately go to the track where the train is leaving, because that’s where the ticket machine is supposed to be. No such machine. I go downstairs to find a machine there. I find one, enter where I want to go, it asks me to pay. It accepts none of my cards. I ask a Deutche Bahn guy who tells me that I can buy my ticket at another track. When I go there, there’s a line. Mainly foreign people like me who have no idea how the railway system works. When it’s finally my turn the sun blinds the screen. I can’t see anything. An impatient german woman behind me asks me where I want to go, presses a couple of buttons and after paying, the ticket comes out. Great.

I arrive at the station around 12.00. At 12.15 the train to Holland leaves, however because I wasn’t sure that I would make it in time, I reserverd seats for the one after… the one that leaves at 16.45. So I have to wait. And I can tell you, 6.5 hours is a VERY long time. Finally, at around 21.30 I’m back in Holland where my dad, who happened to be in the neighbourhood comes to pick me up.

Although the stories may not particularly show it (because I’m only telling what I want the world to know ;)) I’ve had a great time in Latvia and I’m going there again from July 24th to August 4th. Looking forward to it already. You can find the “rest of the pictures I took while in Latvia here”:http://www.zefhemel.com/~zef/Latvia/Latvia.html.
