In MVCC systems like PostgreSQL, if you don't vacuum (garbage collect the old tuples), your database is append-only and you can query as if your transaction was started at some time in the past. I don't know how to set auto-vacuum

You're confusing symmetric and asymmetric cryptography, it's such a basic mistake that maybe you should not comment on cryptography until you've read some more. SHA-256, SHA-3-256, BLAKE2, BLAKE3, etc. are all not-broken and

Your evidence is that the signal app client knows your phone number and can see your contacts list and your groups and your chat messages, and if it is malicious, it could just send all that to the server which could just store it in plaint

Telegram is used widely by Russian speakers everywhere.

by wolf550e 5y ago
The opposite is the truth. The signal servers don't know who talks to whom, and they chose phone number as identifier specifically so the app could use your local address book for contacts and not store your contacts server side.

I believe this is not correct for future scheduled events for humans. When a human sets an event for 8AM on some day 3 years in the future (maybe through a recurring weekly event), what they mean is "8AM local time in that jurisdiction

Right. Without really solid evidence, it might look like a military junta asserting control over the people's elected representatives. Someone who's not an elected politician would have just lost their security clearance and been

They inherited the military of the Soviet Union, which was overhyped but large and not obsolete. They have invested money into keeping up with tech in principle, i.e. a few demo units, but they don't have money to actually equip their

Let's assume the US had better intentions toward Iraq than Putin has towards Ukraine. But the people of Iraq are not thankful for the results of the US invasion. It did not bring peace and prosperity to Iraq.

When other countries join US adventures, it's not because of the NATO defense pact.

This is technically true and also 100% bullshit. It is phrased that way, but I have never heard anyone actually believe that NATO is anything except the US promising to use its military and its nuclear weapons to defend weaker European stat

The worst thing about the US invasion of Iraq is the civilian casualties of the war, occupation and political instability that followed. But the 2nd worst thing about the US invasion of Iraq is that it is indefensible. This weakens the US p

The problem with "density" is that designers use power optimized transistors for some things and speed optimized transistors for other things, on the same manufacturing process. Also, the quality of standard cell libraries matters

Yes, anyone who cares about chips has known this for years. It's the same as software engineers who don't know what SIMD is or think the CPU in their laptop or smartphone works like a MIPS they studied in college. When something l

On laptop, you would get data loss / corruption on sudden power loss. This is rare. With "flush to storage device's RAM", even a kernel panic would not lose data if you let the storage device flush to flash without power

Didn't Powell build his career in part on lying about the My Lai massacre because he was told to? I'm too young to know, but did he really have a reputation as someone who would refuse to lie if the White House told him to lie?

I believe you can compress into the source buffer and keep the read offset ahead of the write offset, but I don't think you can decompress this way.

deflate is implemented in hardware on game consoles. PS5, in addition to zlib, has hardware [0][2] decompressor for RAD Oodle Kraken [1], which is of course much better than zlib. If at all possible, especially if you control both ends, ple

Both things are true. The Soviets were very afraid of NATO because NATO was always richer and had more population and industry. So the Soviets wanted a lot of buffer. To have the front far away from Russia, and be able to fall back a long w
