TCP 與 UDP 協議的 socket 通信

[$] Cache awareness for the CPU scheduler
The kernel’s CPU scheduler has to balance a wide range of objectives. The
tasks in the system must be scheduled fairly, with latency for any given
task kept within bounds. All of the CPUs in the system should be kept busy
if there is enough work to do, but unneeded CPUs should be shut down to
reduce power consumption. A task should also run on the CPU that is most
likely to have cached the memory that task is using. [This patch\

I went on a small hike, just 12-13km this time. The weather was great, blue sky, sunny 18°C, but with the wind it felt colder. Leaves and other green stuff is exploding like crazy. It looks super beautiful right now.

I came across an unfortunately dead salamander on the forest road, some fenced in deer, heaps of sheep, some unmagnetic cows (some were aligned very roughly north-south, but mainly with the axis of the best view I believe), a maybeetle and finally an awesome sunset. Not too shabby! The sheep were mehing all the time, that was really lovely to hear. And the crickets were already active, too. Didn’t expect them to hear yet. I tried to record the concert, but the wind messed it all up. Oh well.

Interestingly, you can abuse the scoring system (not manually, only with a script). Since the mouse jumps to the locations along the circle, you can just use very few steps and still get a great score because every step you make is very accurate – but the result looks funny:

Mt. Stuifen is 757 meters above sea level, has a small shelter and a barbie area and is still the most boring one of the three. It’s also the one farthest away from me. Not sure why it has two summit crosses, but both aren’t at the summit. The third, makeshift one at the real summit was gone by now. Four years ago, somebody had cobbled one together and put it up.

We bought our tucker at a local bakery on our way. This was the first time I tried a Teufelsbrezel (lit. devil’s pretzel), a lye pretzel with pepper. Haven’t come across that anywhere else. But I can certainly recommend that, it’s yummy.

We were glad when we were finally back home after some 26 or 27km. I won’t do much today and let my feet rest. Another friend called for a much, much shorter hike tomorrow.

Golang 網絡編程：像 C 語言一樣操作 Socket
在 C 語言中，進行網絡編程通常使 socket()、bind()、listen()、accept() 等系統調用，而在 Golang 中，我們既可以使用 net 庫提供的高級封裝，也可以直接使用 syscall 庫進行底層操作。本篇文章將簡單的介紹 Golang 如何像 C 語言一樣進行網絡編程。使用 net 庫進行 TCP 編程（推薦方式）Golang 的 net 包對 socket 進行了封 ⌘ Read more

We had a very sunny day, peaking at 19°C. This not only decoyed me out, but also plenty motorcycle terrorists. Eh fuckwits, nobody wants to listen to your bloody engine and exhaust noise, keep it quiet for fuck’s sake! Many of your rider collegues can manage it, too, so should you.

I had some sore muscles after yesterday’s waste paper collection with the scouts. So, I only went for a short trip to my closest backyard mountain. Watching two rock climbers was interesting. That’s not something I see very often.

10 Male Characters Played by Women
Casting can be counterintuitive. Studios often hire male actors for female characters and vice versa. Such decisions aren’t that unusual, especially in this age of gender-swapping established stories. For better or worse, they’re a fairly common practice nowadays, meaning they no longer draw the widespread attention they once did. Ironically, it’s the less overt examples […]

Trump Reveals Tariffs Plan to Ruin American Farmers’ Lives
Malcolm Ferguson,  Associate writer  -  The New Republic

Stephan: Thanks to the stupidity of “king” Trump, who clearly does not understand what tariffs are, Americans, like you and me, are about to see a number of farmers go broke, and the prices we pay for produce at the grocery go up by as much as 25%

I went on a 5:30 hours long hike to my second backyard mountain. About 12km to get there and roughly 9km on the way back. It was super nice, sunny all day long, 12°C and luckily just a little bit of wind. Great scenery. I managed to capture one great spotted woodpecker hammering along. There was also a kestrel hovering over a meadow and then landing on a sports field light pole. At the castle ruin I could watch 10-12 gliding red kites (with the V-shaped tail) and other raptors, maybe bussards, I don’t know, for about five minutes. That was fascinating. Unfortunately, my camera doesn’t too well with moving targets.

We went up our backyard mountain again right after lunch. The sun peaked through the clouds sometimes. The 6°C felt much, much cooler with the northeast wind. We got lucky, though, it was dead calm at the summit. At least on the southwestern side, which is a few meters lower than the very top to the east. That was shielded absolutely perfectly from the wind (we were extremely surprised), so we sat down on a bench and could really enjoy the sun heating us up. Apart from the haze, the view was really nice.

There were even patches of snow left up top, that was unexpected. Also, somebody created a cool rock art piece on a tree stump. That one rock absolutely looked like a face. Crazy!

10 Unbelievable Reasons for Why People Faked Their Own Deaths
In the United States, pseudocide, or faking one’s own death, is not a crime in itself, but the Federal Bureau of Investigation (FBI) warns it almost certainly leads to numerous serious criminal offenses. James Quiggle, director of communications for the Coalition Against Insurance Fraud in Washington, D.C., explains it like this. Essentially, you are defrauding […]

@falsifian@www.falsifian.org Neat, I got the principle, so mission accomplished. :-)

I have configured my vim to use a tab width of four. So, I noticed that especially https://www.falsifian.org/blog/2021/06/04/catalytic/reachability_with_stack.cc (but also partially the other C++ file) mixes tabs and spaces for indentation. :-)

It was mostly cloudy, but every now and then the sun peaked through. With very little wind, the 12°C felt quite nice. Especially for a hike. With the sun completely hidden and more wind, the lunch break at the summit was a bit chilly, though.

There’s a bad looking crack in the climbing rock in 10. When you have eagle eyes, you might be able to see the hooks in the cliff for the climbing ropes. I haven’t seen this one before. Also, it looked like several cubic meters of earth, grass and rock fell off the top.

On the way home, it got much more sunny. I found yet another skyrocket stick. That was pretty neat. And we saw the first field of snowdrops. With some bees checking them out. In total we walked a bit over 15km.

Very sunny 16°C, heaps of people outside. As soon as we were a bit further into the forest, we had it completely for us. From the foot we thought that the view might be rather good, but up at the summit, it turned out to be very hazy. Oh well. Surprisingly, I found four skyrocket sticks in premium quality. More than after New Year! Also, we came across two deer. It was a very nice two hours walk. No photos, though, sorry.
