**I have a job now!**
I'm a Chinese shitizen, but I generally don't post in Chinese to avoid being suffering from other Chinese.
I'm physically a male, but I don't care how people think about my gender. I can be male, or female, or cat. But if you ask, I'd prefer to be referred to as a male. Also, I support LGBT+ people, and I'm a copyleft. I don't think I'm too aggressive in arguing things, but sometimes I do. You should handle it with care.
I post about programming (most time is Java and Kotlin, unless I have a new love), and some random things I find interesting. I also post about my mental health, which is in a stable state of instability, thanks to my parents and Chinese society.
Anyway, if you want to follow me, I'm glad to see you. And, have a nice day.

Well, although windows is suck, the powershell is not bad. I like it more than bash.

为了在圣诞老人真实性上最后挣扎一把，问娃你猜圣诞老人现在在干嘛？是不是在包装礼物呢。
娃：应该是在准备报税文档吧。
我：？
娃：你看他有那么多礼物要买要送呢，税务上应该很不好处理。
我：？？？
一时间竟不知道他是不是早就看破了事实真相反过来在耍我...

Friend: it was so cold other day.
Me: so?
Friend: my laptop froze.
Me: 😦
Friend: it was my fault. I left too many windows open.

Do you need a fun game for the kids for Christmas this year? 😰🤣
This is technically a backup. While cygwin has some performance issue with pipe, I can avoid that by letting dd read the whole disk and write to tape.
It's hard to read (have to dump to a spare disk then pick the file I need), but it still cound as a backup, I guess.
Tried a bunch of method to speed up/buffer the write speed to tape drive in Cygwin. Then found out the pipe itself has performance issues.
With `dd if=/path/to/test/file of=/dev/nst0 bs=4M`, it can easily get 160MB/s writing speed. But with `dd if=/path/to/file bs=4M | dd of=/dev/nst0 bs=4M status=progress`, I can only get about 65MB/s.
That's not usable.
Wrote a hacky bash script using LTOEnc (a windows cli tool for setting up LTO hardware encryption) and tar to backup my PC. (Using Cygwin)
But I'm confused with `tar -b`. With larger blocking factor, each record get bigger but when dealing small files there are more space wasted. I'm backing up both C and D drive, where D drive lives my code and movies/animes/shows.
Don't want to be too extrem on parameters, so I use `-b 1024` and enabled compression to make balance.
Also enabled encryption. While I don't want to encrypt long time archive, backup is a more short term thing, which I'm pretty sure I won't forget the password.
Should be fine I guess? Now I'm testing it.
Want to test how good the hardware compress is. So I decide to test is using block number. I assume the block number will be smaller if compression reduce the total amount of data write to tape.
But then I suddenly realized, that compression is transparent to the system. No matter compress or not, the block number is same since I use the same dataset to test.
So now I'm measuring rewind time😋
hmmm
looks like stenc cannot be compiled under cygwin.
Still, not found any way to enable hardware encryption of my LTO tape drive.

印象中两年还是一年多以前，在fedi刷到一条嘟大意是：加拿大社工以及政府的服务逻辑并不是为了让人们获得资源，而是不让人们得到这些。我当时觉得非常反直觉，隐约觉得能懂但也没太想明白。但工作时间久了接触到的case多了之后完全理解了那段话。我最近才知道这边的工人赔偿（worker's compensation），在claim和拿钱阶段都不能工作或者是有非常严格的限制工作条例，背后逻辑是所谓“保护工人”，既然你受伤了为什么还要去工作？工作了不就说明你可以工作不需要补贴？
但实际上，claim的过程通常非常繁琐非常漫长，在这段时间里你拿不到钱，但是也不能工作，就等于完全断了收入来源。而且不仅不能工作，也不能去上学。我有个case是client因为长期在Child and Family services工作，如果有相关经验的人看到CFS这个缩写都应该知道这个领域压力有多大。她工作的领域非常前线非常高风险，直接面对了caseload中太多死去的儿童之后觉得自己不能继续做了，在supervisor建议下申请了精神工伤补贴。听起来很健全吧？精神工伤补贴都有哦。
但是政府一是刁难认证过程，说你要怎么证明这份工作确实给你带来了精神伤害？于是她花了二是用大量的paperwork和漫长的等待时间折磨人，申请过程非常繁琐，而且精神工伤的claim是很容易失败的，那么等待期的零收入就全是沉没成本。但她还是通过种种努力很不容易地成功了，但是呢，在拿到这笔钱中间又被拖了很久而且仍然有很多钱还没拿到，这期间也还是不能上学工作。期间她申请了一个在线项目，但因为不能上学一再推迟最后取消了。此外，申请工伤赔偿还需要用掉也就是清空all the holiday hours，如果在之后找到的工作里她需要喘息都没有机会再用这个假。在这些漫长的反复拉锯里，我的client说她最明显的感受是“政府是在想尽办法证明我不能得到这些”。可能有些人会觉得，这些都是那种陷入贫困陷入绝境没怎么受过教育的人吧，否则也不会对这些程序都handle不了——我这个client有三个degree。And that's how the system works.
Wait, what?
Cygwin can detect my tape drive and put it to /dev/st0?
Now I'm going to read the 9th chapter of tar manual.
Also I noticed the JVM's impl of SHA3-256 doesn't perform well. It's kind of 150MB/s and can't saturate my tape drive which can read 160MB/s.
I have no issue with Bouncy Castle's impl which is purely in Java.
I thought native impl is better. Why? (I tried Java 21 LTS, no improvement)

Finished two tape cartridges. One more to go.
But at least I think my software is working and usable. Although I notice HPE include utility tools that functionally similar to mine.
Anyway, for anyone who use LTFS with LTO 5 and later tapes, you may have a try:

最近在做跨境汇款的一点点经验总结。
1.尽量不要使用中国银行，如需使用，请提前致电客服查询自己的跨境转账限额，以及国内转账限额。
2.每年五万美金限额是指购买限额，是央行直接统计，按身份证号码统计。你的卖出并不扣减。比如你买了五万卖了一万，再想买一万是不可能的。换银行也不行。
3.如果遭遇转账限额，app提示超出限额，打客服咨询解决办法，如果本人不在国内，客服表示无法解决时，要求对方寻找可解决的主管。并且登记你的问题，给出问题记录号码，会在三个工作日后，有你的开户行工作人员联系你。
4.如果遭遇转账限额，本人在国内，可持本人身份证到网点或开户行解决该问题（提升限额，或临时提升限额）
5.限额问题四大银行均有，目前国内银行大概有钱荒，未来可能会更严重。直接后果是，自己的钱在账户，但是，转出或取出存在障碍。
最后，人如果在国内，我没啥建议，找个信得过的非四大银行？我也不知道。
人在海外就是，钱转出来就ok了。
