At around midnight I had a very hard time to stay awake all alone in the hostel's living room. Reading as a pastime wasn't a very lucky chouce, but the only thing I could think of (btw: read Lina Ben Mhenni's book about the Tunisian revolution. Great report! Found it in German and French only, though). My sleep was rather light and I recall waking up twice and in the morning I woke up about 15 minutes prior to my alarm clock. Feeling good.
Nap 1: At the beach again, about 15 minutes early. I was quite tired and slept very well. This was a great, deep and refreshing nap.
Nap 2: At around 5:45 pm I fell into a light slumber with frequent wake-ups in between for about half an hour. I tried really hard not to but couldn't hel it, I was too tired and bored on the train ride back home. Back in Hamburg I laid down at a less crowded spot et the lakeside in teh city center and felt a little like a bum, but had a quite okay 15-20 minutes nap.

This night I went to bed early, at 2 am, and got up in time without any trouble. Today and tomorrow I'm on a bike tour with friends, so this going to be a small test for my sleeping cycle.
Nap 1: During the trainride from 8 to 10:30 am I was so tired I had a really hard time not to fall asleep and yawened constantly. I guess it was a consequence of getting up in time and cutting out the extra 1.5 hrs I had the last three days. And trainrides are boring. At 12:15 pm we were at a beach at the baltic sea. Nice, warm weather and I took a nap on the sand. Totally messed up my timer, but woke up by myself after about the right time an dfelt great.
Nap 2: Biking all day was good and fun, but shortly before I went to bed I read three very annoying and upsetting emails. Although I thought I feed my mind of those thoughts, I wasn't sleeping well. I had the best conditions, however: dark, silent room, alona in a bed. I woke up after ten minutes, reset my alarm and tried to nap again, but this time a weird noise woke me up again. I remember having dreams in both short naps, so I guess I had at least some rest.

Argh! I overslept by 1.5 hrs again. I really need to work on getting up after my core sleep. I'll try with harder discipline. Feeling tired right now.
Nap 1: I was about half an hour late for my nap but slept well.
Nap 2: At about 7 pm I almost fell asleep. Made it hardly until my naptime at 8 pm but had a good nap then.
Samstag, 1. Oktober 2011
Getting up after my coresleep is the hardest thing to do right now. Switched off my alarm at 7 am and then turned right back into sleep. Overslept about 1.5 hrs again. I'll try with more discipline next time. Just getting up, no matter what. Hopefully my naps will work better this time.
Nap 1: This was a nap how I imagine it should be. Falling asleep, waking up, feeling good.
Nap 2: Was good, too.
Talks about Sleephacking
I found two talks so far. If you know of any other talk, let me know in the comments.
Joe Betts-LaCroix tried the 28-Hour Day inspired by xkcd's comic strip
Christiane gave a Lightning Talk at the 26c3 quickly introducing the topic. Search the Lightning Talks Day 1 video in this list and start watching at 1:42:00.

Last night's sleep was okay, but I had a tough time getting up this morning and slipt back into a light slumber a few times before I could escape the bed about 1.5 hrs later. Maybe my previous naps weren't as restful as I needed them.
Nap 1: I dozed off for only 10 minutes and then reset my alarm to get a good nap. Feeling very good right now.
Nap 2: About 20 minutes late, didn't fall asleep, reset alarm clock, then overslept by a few minutes, but I feel okay. I guess oversleeping in the morning messed me up a little.
Different Types of Sleep
I tweeted it before, but I found it so funny and experienced some kinds of these already: Top Eight Kinds of Nap. I'm very excited about experiencing the last kind where you sleep for a few minutes only, but have long, vivid dreams that make you feel you slept for hours. Other poly sleepers reported to get these after about a month of staying on schedule.

TimeCorrection add-in for f-spot Geschrieben von Jan Girlich in technique um 18:38
This add-in for f-spot semi-automatically corrects your photos' time to UTC. This is great if you want to
- import pictures from multiple cameras and keep the order of time
- correlate your pictures with GPS data to add position information
The idea is to take a picture of the UTC time as a QR-Code and correct all photos by the difference between the UTC time encoded in the QR-Code and the camera's time encoded in the EXIF data.
If you run f-spot 8.1 check it out. I'd love to get some feedback. (Source: patch against stable-0.8 branch of f-spot)

Falling asleep at night was no problem. In the morning I woke up exactly one minute before my alarm went off. And I felt better than any other morning before. Took only little time to get out of my bed. Best morning so far.
Nap 1: I fell asleep, I woke up before my alarm, I did not feel very rested for 20 minutes, but then I felt good.
Nap 2: I was about one hour late and again had the kind of nap where it feels like you only closed your eyes for 25 minutes without falling asleep. But I'm pretty sure that I was asleep. Felt quite rested a few minutes after the nap.
Usages of Polyphasic Sleep
I'm wondering why altrenative sleep patterns are a fairly unknown topic. Did you ever before hear of this or anything similar? I learned about it this year. But there are many advantages (and disadvantages like being out of sync with other people) one can make great use of. Every person in the world is able to do this, it doesn't need any special equipment or something else. So why are only few people using other sleep patterns? Well, there are some people who do. http://en.wikipedia.org/wiki/Polyphasic_sleep#Napping_in_extreme_situations Wikipedia has a section on where polyphasic sleep is used. Soldiers, astronauts and one-hand sailors use polyphasic sleep patterns for better performance in extreme situations. Makes me feel a little less geeky
If you find any further sources on usages like the above mentioned ones I'd be happy to read them.

Again, the evening was just fine, but the morning was not perfect. I couldn't get up with the alarm and overslept about 45 minutes. Still in the adjustment phase I guess. But after that I feel awake and alert and ready to get going!
Nap 1: I moved this nap about half an hour ahead because it collided with an appointment I had. When I laid down it didn't feel like I really fell asleep. More like dozing off and slumbering. But time passed quickly and I felt okay afterwards
Nap 2: Same thing again, I didn't feel like I really was asleep, more like dozing a little, but time passed quickly again. In both cases I was awake before the alarm went off. Not in the best shape, but I already felt worse after a whole night of sleep.
Since I started this experiment I got feedback ranging from 'Awesome, I would love to do that myself as well!' over 'Hm, would be interesting to see how it turns out for you.' to 'You are crazy, this is plain stupid suicide!'. Well, I tend to see an invers proportionality between negative criticism and knowledge about the topic. The more people more, the more they seem to want to do it as well. Or: The people yelling the loudest understand the least.
I noticed two things people mostly misunderstand and sometimes don't even want to understand:
1) This is not about sleep deprevation, which is bad, but to get the amount of rest you need in less time. It's about sleeping more efficient.
I try to get the same amount of REM phases like everyone else, but in a different pattern spread around the day, allowing me to cope with almost half the sleeping time less. I'm usually fully rested, but skipped a few sleep stages that don't seem to be important to your health and well-being as far as science can tell.
2) How can you assume the way you're and almost everyone else you know is spending their nights is the right and only way?
Before the advance of artifical light sources people would during winter go to bed at about sunset, have a rather light sleep, wake up at midnight for a few hours and spend this time to talk about their dreams, have sex, eat and even visit friends and neighbours. Then they would go to bed again for a second phase of sleep. It was for long the natural sleeping pattern of humans. You can find historic sources describing this online and even remains of these habits are to be found in modern languages like 'beauty sleep', which was the first phase of light sleep which usually was accompanied by 'beautiful' dreams. A good start on this is the wikipedia page on segmented sleep.

Tonight's coresleep was good. Fell asleep immediately and woke up just a few minutes before my alarm went off. I had no problem with stkipping my second nap and got out of bed quite quickly and painless. Having a good start into the day.
Nap 1: Shortly after reading Rolf's blogpost about his nightmares, I went for my nap as well. I fell asleep quite quickly and had a dream. Usually I can't remember any of my dreams, but this time I did. And guess what, it was a nightmare! Incorporating my mom's wish to redo the bathroom and moving tons of stuff around to empty it out, cramming my room so full I can't even open the door properly anymore and blocking my way to my medication while I have a serious asthma attack and barely can breathe. It felt very real and it took me a while to realise I didn't have an asthma attack and could breath freely when I woke up (Ah, breathing can feel so great!). This means I woke up by myself during a REM sleep phase, three minutes before the alarm. Good for me
Nap 2: Because of the sneak preview I had to move my second nap forward by half an hour. I used my mobile phone with earplugs to play rainymood and to wake me up with a countdown timer app. Worked great. I also got a sleeping mask to cover my eyes for my midday nap.
During a usual night a person has five REM phases within about 8 hrs (if you don't know what REM is, look it up). The idea of Everyman 4,5 is to reduce the number of REM phases at night to three during 4,5 hrs of coresleep. The other two REM phases should be achieved during short (about 25 minutes) naps during the day. It's crucial to find the right length for your nap so you don't wake up too early before going through a REM phase and not too late because you feel most refreshed shortly after or right at the end of a REM phase. But if you sleep longer you enter a different sleep state and waking up is harder and will leave you groggy and unrested. The hard part about the adjustment phase is to train your body to enter REM during these short naps and finding the right length for your naps.

Staying awake until bedtime wasn't a problem after all. But staying awake the next morning is. I wish I could go right back to sleep.
Nap 1: After a slow morning not getting ahead with anything I felt quite good at about 11 am. Then I got some things done and was about 20 minutes late for my nap. Unfortunately my mom woke me up in the middle of my nap and I reset the alarm and fell asleep again. It was a fairly good nap.
Nap 2: Since I was in the theater and watched "A Clockwork Orange" I couldn't take my nap as usual. I got very tired at around 8 pm, but I had no trouble following the play. Later I felt awake and alert enough to skip the nap altogether. We'll see if I'll regret this decision.
All in all this is goin way better and much easier than I expected it to be. I was expecting to feel extremly sleep deprived and hardly functioning by now the latest, but I'm doing quite fine.
I tend to drink a lot of coffee, Club Mate, and sometimes Fritz Cola. But I read and heard quite often not to consume any caffeine because it messes with your sleep cycle. So far I had a cup of coffee after getting up and with about 6 hrs until the next nap I assume this is enough time to get the caffeine of one cup through my system. But in general I'm seriously considering weening myself off this habit.

Apparently I had two pen pals from the US and Canada back in 1999. I can't remember writing them at all, but while cleaning up I found two responses. I think it was through school and didn't last for long, but now I feel it's a shame we didn't stay in touch. Both came printed out on pieces of paper. Looks like all letters for a whole class were put in one email and then cut into strips.
The other one was printed on a page titled "re: letters from La Canada" with the date of October 1st 1999. I was alrmost 17 back then.
See what awesome pen pals I had?

Falling asleep was easy and no problem at all. But, ugh, I remember the alarm going off, but just a second later it was 7:50 am. Something must've happened. But I felt good after getting up. sTartetd right off being quite productive, though I don't feel really rested.
Nap 1: At the library, laying on a table, with a scarf covering my eyes and earplugs with rainymood.com on them. It was a bit tough. I dozed off multiple times and I think I didn't get enough sleep although I woke up bymyself a minute before the alarm went off. Feeling only little refreshed and yawning a lot after the nap.
Nap 2: Ouch. I fell asleep very quickly, but my brother woke me up after about 20 minutes. I reset my alarm and took another nap of 25 minutes and after this one I felt really bad. It's going to be hard staying awake for the next 5.5 hrs until 2:30 am. Maybe crafting on my ship model will help me stay awake?

After hearing of non-monophasic sleep cycles through some friends in Ulm, Germany, I got very interested in this topic. I tried earlier to get more off of my sleep by trying to follow the tips from lifehacker and I even got a Wake-Up light since they supposedly helping you to get better rest from your sleep. Well, that's all nice and stuff, but I still sleep irregularly and need almost 9 hrs of sleep every night.
I read all of Steve Palina's experiences with a sleep pattern called 'Uberman' and had a look at other sleep cycles. I decided to try the same pattern as ulmnotsleepy eventually settled on, which is:
2:30 am - 7:00 am: core sleep
1:00 pm - 1:25 pm: nap 1
8:00 pm - 8:25 pm: nap 2
The experiment started on Thursday, September 22nd and I'm in day 3 now. About 1 hour to go for nap 1 which will be interesting because I'm at a library and don't plan to move much. Maybe a table will accomodate me for half an hour?
Here are some more links on the topic and after that is a short log an my last two days.
Day 1 (22.09.2011)
Went to bed at 2:30 am the previous night. Actually wanted to go to bed earlier, but this way I caught up a little on my reading.
Woke up at 7 by my alarm, felt very tired, turned over and slept until 8:10. Felt much better then and been doing my usual morning routine since then. But at 9:15 I'm yawning a storm and think I'm gonna have a cup of coffee.
Nap 1 at 12:55 pm was only medium successful. Couldn't go to sleep for about 15 minutes, then reset the alarm clock for another 25 minutes. This time I slept and it was okay. Feeling a little drowsy, but okay.
Nap 2 was a complete fail. Tried to fall asleep for about 35 minutes from 7:55 pm on, then I gave up and got a haircut. Hopefully I'll be able to stay awake for the next 6 hrs. Maybe I'll go out on a concert, that'll help.
At 12:45 am it was hard to stay awake. Yawning, eyes falling shut, I wanted to go to bed, but had to wait for another 1:45 hrs.
Day 2 (23.09.2011)
Going to sleep was no problem. I was a few minutes late. This morning I got out of the bed at 7:10 am. And it feels way too early. Going to take a shower and get a coffee to get me started. Then off running errands.
Nap 1: took a while to fall asleep. When the alarm went off I couldn't tell how much time I spent waiting to fall asleep and how long I slept or if I slept at all. Don't feel any different than before. A bit tired, but okay. I'm pretty sure I slept about 20 minute, though.
Nap 2: 10 minutes later than planned and right after a heavy dinner (lamb steak). Again I was wondering how long it took me to fall asleep and it seemed like ages. But suddenly the alarm went off and I realized I was indeed sleeping deeply. Feeling quite refreshed and productive now. At 6 pm I felt very tired and couldn't wait for the time to pass until my next nap.

Positive Erfahrung mit Alice: neuer NTBA Geschrieben von Jan Girlich in Rest um 04:00
Nachdem ich ausführlich über wenig kompetente Antworten von Alice bzgl. IPv6 und der problematischen Rufnummermitnahme berichtet habe, hier nun ein Bericht über eine positive Erfahrung. Leider sind positive Erfahrungen meist auch deshalb so gut, da sie so schnell waren, was dazu führt, dass es nicht so viel zu Berichten gibt.
Seit einiger Zeit, sicher schon ein Jahr, haben wir Knacken und Rauschen auf unserer Festnetzleitung. Es scheint von der Mondphase und Luftfeuchtigkeit abzuhängen, ist manchmal komplett weg und dann wieder so laut, dass jedes Gespräch unmöglich wird. Also rief ich mal bei der Hotline an, die mir sagte ich solle vom Handy aus anrufen, da die Leitung zum Störungstest nicht benutzt werden darf. Mit dem Handy superteure Hotlines anrufen und Warteschleifen bezahlen? Ich bin doch nicht blöd! Und sowieso: Internet geht, wer telefoniert heute schon noch? Falls doch, dann reicht es den NTBA kurz abzuklemmen, dann ist das Rauschen für ein paar Stunden bis Tage weg.
Leider telefoniert meine Mutter noch. In der Zwischenzeit fand sie die kostenlose Störungshotline, die ich dann vom Handy anrief. Ich war total baff: Nach einer Minute hatte ich einen kompetenten Techniker an der Leitung. Der ist mit mir das Protokoll durchgegangen. Jetzt bitte mal hier und da und an die eigene Nase fassen und rauscht es immer noch? Ja. Dann bat er mich den NTBA für die Leitungsüberprüfung aus der TAE abzustöpseln. Daraufhin sagte ich, dass wir das gerne machen können, aber er würde nach dem Störungstest der Leitung nichts finden und dann wird das Rauschen weg sein, da der NTBA vom Netz getrennt war. Dann würde ich da stehen wie ein Idiot, denn offensichtlich ist ja alles in Ordnung und wenn ich dann in drei Tagen, wenn das Rauschen wieder da ist, mit dem nächsten Techniker sprechen und wir das Protokoll wieder durchgehen wird sich das wiederholen. Das hat ihn wirklich überzeugt (!) und er sagte er kreuzt den Test einfach mal als durchgeführt an und wir schauen weiter. Boah, war ich begeistert!
Leider kam dann das nächste Problem: unsere analoge Telefonanlage. Wir haben nicht ein ISDN-Telefon und der Techniker hätte doch gerne die Telefonanlage als Fehlerursache ausgeschlossen. Kann ich nachvollziehen. Nach nur einer Woche hatte ich dann endlich mal von einer Nachbarin ein ISDN-Telefon ausgeliehen und getestet. Das Rauschen ist auch mit ISDN-Telefon präsent.
Nebenher hat Alice mal wieder Mist gebaut. Wir hatten uns darauf geeinigt, dass ich mich bei Alice melde wenn ich den Test mit dem ISDN-Telefon gemacht habe. In der Zwischenzeit wird der Fall aber intern an eine andere Stelle, die evtl. auch einen Außendiensttechniker entsendet, weitergeleitet und die würden sich möglicherweise nochmal am Montag melden. Aber im System wurde auf mein Bitten hin vermerkt nicht einfach auf meinem Handy anzurufen (mag ich nicht, ist immer auf lautlos), sondern mir eine SMS zu senden auf die hin ich dann wieder die kostenlose Hotline anrufe. Alice hat aber stattdessen am Sonntag auf dem Festnetz angerufen, meine unwissende Mutter komplett verwirrt und als ich anrief war der Fall bereits als geschlossen und gelöst markiert.
Aber bei meinem zweiten Anruf hatte ich dann wieder jemand Kompetentes an der Leitung. Die Person hat den Fall einfach wieder geöffnet, wollte aber dann mit dem Protokoll von vorne anfangen. Daraufhin habe ich der Person geschildert was wir bereits gemacht haben und was die Ergebnisse waren. Und dann hat er die Schlussfolgerung gezogen, dass es ja am NTBA liegen müsse. Mein Reden! Nochmal einmal den NTBA abklemmen, nur um das nochmal zu testen. Kein Ding. Und dann kam tatsächlich zwei Tage später ein NTBA. Eingebaut und kein Rauschen. Mal sehen ob es die nächsten Tage noch in der Leitung rauscht, aber es scheint alles in Ordnung.

Yesterday I went on a little geocaching tour deciding spontanously on which caches to try. 2 out of 4 were climbing caches although I wasn't prepared and were wearing the most slippery shoes I own. I didn't care, dropped my backpack at the trees' trunks and climbed them. No safety gear, no person knowing where I am and what I'm doing. Up in the treetops of about 5 m (~15 ft) and maybe 8 m (~24 ft) I picked up the caches' logbooks and took a few pictures. Then I got down, took the bus and went to the sneak preview. It was about an hour later when I realized: Wow, that was pretty dangerous! I could've fallen down and break my neck! Those trees were tall!
That's the moment I knew I'm a grown-up now. When I was young I did the same things and many crazier things, but never thought about how dangerous they were. Now I do. After I did those crazy things, but I do weigh the risks.
