Re:Debian project has plenty of money but not enough developers on Friday September 11, 2020 @05:03AM (#24440560)
The Monero cryptocurrency's developers are all funded via the community via bounties. I think it works really well.

Re:# of days since the last alg=none JWT vulnerability on Tuesday September 01, 2020 @07:06PM (#24348164)
Slightly OT but why should I choose a JWT over creating some opaque token (random bytes) and storing that in a database mapping it to a user's ID?

It seems like people create short lived JWTs and then pass some opaque token to an auth endpoint to get a new JWT signed whenever the old one expires, or they store the JWTs in a database so that they can be revoked, making me question their usefulness.

Re:GraalVM on Monday August 10, 2020 @12:53AM (#24105675)
You need to pay Oracle $lots for a GraalVM enterprise licence to get profile guided optimisations, if you want some of your peak performance back.
Re:Compiler Explorer on Thursday August 06, 2020 @01:52AM (#24068444)
Try making your class final. Then it won't bother looking up the address of the virtual function in cases where it knows which class it is.
Having a proof of work function that did something useful outside of minting new blocks would be awful for a cryptocurrency.

You can opt-in to sharing some info with the popcon tool.
Re:SaltStack Mining Attack on Tuesday May 05, 2020 @06:57PM (#23086107)
Mining with JavaScript or WebAssembly is no longer viable as being competitive now requires using a JIT compiler.

Nothing can really be done about it. Pool operators can ban the wallet addresses of known bot masters from connecting to their pool, but you can't really ban someone from participating in an anonymous decentralised network.

Epic are anti-Linux.
Re:Speeding up Linux disk encryption on Thursday March 26, 2020 @07:27AM (#22692460)
I use Gentoo Linux so it was as easy as putting the patches in a directory, and then rebuilding the kernel with the option to enable the synchronous cipher.

For Debian it's almost as easy: https://passthroughpo.st/patch-kernel-debian/

Yes, I'm running them on kernel 5.5.13 (which came out today)

See Monero. Transaction senders, recipients, and amounts are hidden by default.

There are also existing cashierless stores in China.

Seems like you can, but probably shouldn't since you'd want to run services like chrony to keep time inside the VM.
Can I run a single process in a Firecracker microVM, or do I need to bring a full distro?
Re:Mozilla’s DNS over HTTPs on Tuesday February 25, 2020 @01:08PM (#22415513)

But how many people are going to change it from the default?

Are you using a broken DNS server, like 1.1.1.1 from Cloudflare?

Don't they still mine asbestos in Canada?

Re:Layoffs hit Quora on Saturday January 25, 2020 @08:22AM (#22146130)
It would be nice if there was a way to block certain domains from Google (or any other search engine) results. There are also a lot of sites that seem like they scrape posts from StackOverflow that I would like to block too.
How do I invest in your startup!?!?

Re:Single-Assignment C on Friday December 27, 2019 @04:19AM (#21890148)
If it's a static method (or in an anonymous namespace in C++), it should get fixed at any optimisation level. However if it's a global method, you'll need to pass -flto to defer optimisations to link time to make it work.
Re:My Business Card Runs Linux on Tuesday December 24, 2019 @11:03AM (#21872866)
Your SIM cards, credit/debit cards, GPG smartcard, Bitcoin hardware wallets, etc. already do (probably) run Java :)
It would be cool if somebody created some provably fair ransomware that used Bitcoin script or zero knowledge proofs or something. You pay the coins and are guaranteed the (correct) decryption key.
