Perhaps it is just travel anxiety? I book hotels a few hours in advance and stats like "only 2 rooms left", are usually correct when I check with hotel reception. At least in Europe booking.com is much better than competition. It has loyalty discounts, transparent pricing and consistent experience. Reviews and descriptions are actually useful, not BS. Emails I get are usually "place you looked at become 30% cheaper".

Does it make a sense to turn it into fuse fs, with transparent deduplication?
Re:Office 2000 is good to go on Tuesday November 16, 2021 @10:41AM (#29241751)
Win95 had very strict and consistent UI style. Office2k and Win2k were peak of this consistency. After that came WinXP and mismatch of inconsistent UI styles.
Re:Java Virtual Threads Preview on Tuesday November 16, 2021 @03:04AM (#29238091)
Java uses some memory for stack, about 1MB for each thread.
For start they could provide private offices. Open-plan office is hygienically unsuitable for regular use.
I had run LineageOS for some time. It works, but FDroid is missing too many apps, even opensource like Signal. I have to update apks manually every few months.
Japan has very good public transport, and does not really need cars.

In america the question is why invest in carbon based transportation? It is "obsolete technology"! In japan cars are "obsolete"!

Better to eradicate ticks.
$10 nozzle repair requires new battery pack for $16,000. Call it what you want, but that is not green car.
Why should people care about some 50 year old obscure cultural references? It is not 1980ies, when 99% unix users were from western culture.
Re:Facebook and Google Are Not Public Utilities on Wednesday July 28, 2021 @11:46AM (#27985183)
Many public institutions treat Google as public utility. Children can not attend school, unless they agree to privacy policy on school issued Chromebook. Town hall meetings announcements are only on FB...

If those are not public utilities, there should be law to prevent public institutions from using them.

I always seen it as public threat that politicians are on private social media, what if private company declares war on our behalf?

Re:Licenses alone do not govern behavior in open source on Sunday June 20, 2021 @02:54AM (#27567787)
OS author also distributes, maintains and supports project. Just compiling some opensource projects (Firefox, Chromium) is very complicated.

I am not sure what happened here. But if large project would use outdated or broken version, author may get bombarded with support requests for problem, that was solved years ago.

It searches content of referenced webpages. Also has filtering by year intervals (for example 2012-2016), domains, tags etc.. And I find usability better.

I think it is great product.

Chariots were invented, but lightweight chariots were VERY hightech and expensive, something like Ferrari today. See youtube link.

Location: Prague, Czechia

Remote: yes, Europe

Willing to relocate: no, remote only, preferably async

Technologies: java, jvm, data, kotlin, scala, defi

CV: https://github.com/jankotek , CV on request

Email: jan @ kotek d0t net

I am consultant with 15 years java experience, last 10 years I worked on opensource projects. I worked on IDE, compilers, but mostly on database engines and data processing. All Java. I have some experience in cryptography and defi. My clients were Apple, a few banks, and some startups that are now worth multi billions. More details on request.

Looking for part time, JVM related, temp contracts. Code audit, refactoring, performance fix...

Re:BPF for storage: an exokernel-inspired approach on Saturday March 27, 2021 @10:37AM (#26602567)
Many databases can bypass filesystem and use block device (partitions) directly. But modifying NVMe drivers is pretty novel approach. Maybe Redis compiled into Linux kernel is not bad idea :)
Re:ZGC – What's new in JDK 16 on Tuesday March 23, 2021 @01:11PM (#26557383)
It really depends on application and complexity of object graph. Short lived object usually have low overhead. Long lived objects with huge heap may cause a problem.

In past GC had bad reputation for increased and unpredictable latencies. In old JVMs GC would pause execution to traverse object graph.

In general do not worry about GC, unless you run into performance issues. If performance is a problem, run continuous profiler such as Flight Recorded. It has very little overhead.

Human brain. IP protocol is computable by humans. There is even RFC for transferring packets over pigeons.
Saturating modern SSDs is not that hard, if datastream is constant. Write performance usually degrades rapidly after couple of hours/days, once caches are filled and fragmentation grows.

But I totally agree modern SSDs will cause shift in computer and software architecture. Dealing with async disk IO is very frustrating.

> [a]: Obviously, for absolute security, a hammer and/or a shredder does much better.

This still leaves large pieces of magnetic plates intact. At uni we could read some data from floppies that went through shredder.

Hammer and shredder is NOT "absolute security".

Hell no!

In this case Github is just unreliable piece of infrastructure. My phone provider bans me for receiving phone call from wrong country? Nice joke.

Hm, yet another cloud based app with zero privacy and questionable life expectancy. Personal notes are very valuable and may go back 30 years.

What I need:

- self hosted server app

- data stored in human readable independent format with revision history (text+git)

- auditable security

- clients for web, mac, android

- integration with other platforms

Ships were often carried across land, for example over Isthmus of Corinth. Ship wood was also expensive, maybe they took and reused some parts...
It quotes Herodotus, this is first link from google, wiki has some pages as well. I am not an historian, but it seems credible. Some details are matching.

Re:Flow Browser Preview on the Raspberry Pi 400 on Tuesday December 29, 2020 @02:20PM (#25573655)
Main selling point of Presto Opera engine was it could run on any CPU. Often on poor feature phones, without MMU, floating point arithmetic...

Raise of cheap full featured ARM CPUs made it obsolete.

》Bees are the only living thing on earth that doesn’t carry any type of pathogen, including bacteria, viruses, and fungi.

That is simply not true. Bees have many parasites, fungi, diseases ...

Re:What’s the best non-smart TV sold today? on Saturday December 26, 2020 @03:12PM (#25546110)
Hacking used to be about modifying your hardware.

Smart TVs are relatively cheap compared to large industrial displays. They are also reliable. If you need large secure (no wifi) display, this is pefectly valid option.

Re:What’s the best non-smart TV sold today? on Saturday December 26, 2020 @02:30PM (#25545773)
Perfectly valid solution, and it gets downvoted on Hacker News...
