You missed the "Beidou" positioning system, your news is too out of date.

Ask HN: Which way for storing client's RSA public key is correct?

For end to end encryption, client should pass his own RSA public key to server after every re-login. Client should have a dynamic RSA public key. Client may have the same credential but with different RSA public keys. Client will generate a RSA key pair randomly after start the app for the first time.In other words, client will login from different devices at the same time.For now all user...

Re:A new way to make maps with OpenStreetMap on Friday April 23, 2021 @10:58PM (#26921879)
As it was said

5 mins? It took me a night to build the map system using openstreetmap in the original way

Ask HN: Is there a reader app/site to store a link for reading the link later?

There are tones of interesting links/images I want to read always when I surf on the internet. But those articles are somehow too long which need me 30mins or more to read. I don't want to put down the work I am doing. So is there any good methodology to read those articles later? I used Kindle, Evernote, Microsoft To-do list, Trello but I need to read the link or save the link or even write...

Re:Ask HN: Where to publish tech blog posts these days? on Friday April 23, 2021 @10:41PM (#26921793)
Medium is nice place but not so nice. If you don't have the intension to build your own brand or try to catch other traffic of those Medium users, you can simply setup a personal Wordpress blog. It's easy and quick. But here's a thing that you might feel so bad if you wanna transfer all your blogs to other platforms. Or you just stay with wordpress(or similar) forever since you can do the backup and whatever you want there. I wouldn't suggest static site generators. Because it store blogs in simple HTML and it's troublesome to interact with readers.

Is there any Rossetta 2 (SBT Static Binary Translation) alternative on Linux?

On an Apple Silicon chip such as M1 (ARMv8), x86 instructions can be translated statistically by Rossetta 2 when the program runs for the first time. It's fast. Because Rossetta 2 does the SBT (Static Binary Translation).I had used qemu to emulated an x86_64 Linux OS on a M1 MacBook Pro and it worked. But qemu is doing the JIT (Just-in-time compilation),the performance is so bad, very slow,...

Some good gdb plugin for vim?

I used vim/tmux/gdb separately. But now I want something can integrate GDB within Vim.I tried Conque GDB which is written in Python. But it was so slow. This video shows how it works with Vim. https://www.youtube.com/watch?v=ZcSjaYSoqnc But on my Linux PC, the Conque gdb plugin view would refresh every time I typed a letter.And I tried vim-vebugger. https://github.com/idanarye/vim-vebugger ...

Sorry to hear that. But really StackOverFlow is place for people to share, ask and answer questions. I think this is mainly a problem of StackOverFlow itself. Amateur admins can do whatever they want to the community. If no more StackOverFlow, where can we ask/answer/search materials?

Do you think stackoverflow is bullying users?

I had been using StackOverFlow and its other products, such as ServerFault for a long time. But recently my account at ServerFault had been abandoned. It's because that one of the community admins answered my question about resecuring a LUKS encryption disk. And the admin thought this was a lame question. He voted down my question. And suddenly my account was abandoned.Why are those amateurs...

Re:What OS should I used daily (Linux or OS X)? on Friday January 13, 2017 @02:56AM (#13389170)
Thank you. I have dig a bit into xquart and found it to be a nice X11 tool.

Firstly, so did you refer that you work on Linux and connect to your MacOS which is running a X11 server using xquarts?

Secondly, how do you manage the files on your Linux machine if you use your Mac as the main machine? Do you use SSHFS to mount your Linux drives on your MacOS? (I'm used to the environment that Linux gives me, and try to work on Mac without giving up Linux tools)

Re:What OS should I used daily (Linux or OS X)? on Wednesday January 11, 2017 @04:35AM (#13372804)
Homebrew depends on git when fetching sources. Sometimes it fails at compiling or so. Not like the binary fetched directly from `apt-get` or others.

For other GNU/Linux package managers, they have package distribution standard (testing). Homebrew maybe give us latest package but I can't be sure whether it's stable and reliable for production.

`apt-get` or others are backed by companies or major communities.

---- But words in short, I really don't want to carry 2 computers (ThinkPad & MacBook) to work, travel or anything. Do you have some suggestions?

Re:What OS should I used daily (Linux or OS X)? on Wednesday January 11, 2017 @04:27AM (#13372774)
Okay. So basically this guy uses docker to set up a X11 server with qt creator and other development environment in a server. Meaning while, the user can use a local X11 client to connect to the X11 server which do the real computing.

But this highly depends on the quality of Internet. Every PC can do it with a X11 client.

This is a good try, but not very practical.

Re:What OS should I used daily (Linux or OS X)? on Wednesday January 11, 2017 @02:58AM (#13372468)
Yeah. But docker is a just a container. Not only do I sometimes develop things in console ( for services) but also develop tools in DE (such as PyCharm, IDEA, QT creator, android studio).

What's the difference if you install GNU/Linux on a Mac, will you regret it?

What OS should I used daily (Linux or OS X)?

I had been using Linux for decades. And I am used to the software and packages on GNU/Linux(Debian). But recently I got a Mac, preparing to develop iOS apps on it. But I found that gradually I had to migrate/port some other Linux tools for OS X. It really costs time to do so when you replace the development environment. GNU/Linux has great tools for developing most things in console. But it...

Thanks for the advice. But AWS cloud will not work in my region -- China.

> There are tools to refresh those certs automatically.

I know these tools. But I have set it up every time. And it will increase the labour work if you have dozens of domains, dozens of servers. Really troublesome to maintain only for the certificates.

Re:How to startup in China on Tuesday December 13, 2016 @02:51AM (#13165266)
The article points lots of the realism of startup in China. However most importantly "Guanxi" is the key if you want to have startup in China. "Guanxi" means 'relationship' generally.

And as the author stats the key is "The dark arts of guanxi". Ordinary people who don't have this relationship with governors, authorities can not have licence to run startups in China. Licences usually cost and are in short. If you use your "Guanxi" to gain license, you are hurting others who are born poor. Think about it if you have conscience.
