This is not quite an accurate telling of rockstar's reaction, there were actually receptive to it and paid out $10k for the discovery. Though it's an understandable mistake given rockstar's hostile history with the gta modding scene.

See the original post and discussion for the whole story:

It's a bit ridiculous to imply Tokuyama gets better shinkansen service than Hamamatsu, because it has Nozomi service.

Looking at the schedule towards Tokyo for Monday, April 27th: Tokuyama has: 4 16 car Nozomi trains to Tokyo 19 8 car Kodoma/Sakura trains to Shin-Osaka 9 8 car Kodoma/Sakura to Okayama

Hamamatsu has: 31 16 car Kodoma to Tokyo 19 16 car Hikari to Tokyo

Keep in mind the fastest Kodoma seems to only take around 1 hr 40 mins to Tokyo, and the fastest Hikaru is only 1 hr 20 mins.

I'm sure it's nice getting a 1 seat ride to Tokyo from Tokuyama if you can get on one of the 4 Nozomis, and unfortunate you can't get a one seat ride past Shin-Osaka from Hanamatsu, but the service levels seem pretty proportionate to me.

This should be at least (2001)[0], if not (2000)[1]

For those interested, the key takeaway from this IMO is that by issuing many sequential reads, the memory controller will hold a target row open for an extended amount of time to service the consecutive accesses.

This is in contrast to the original rowhammer attack, which issues accesses such that target rows are repeatedly opened and closed to trigger bitflips in neighboring rows.

By stretching out the row open time to 30ms (!), the authors claim they are able to reliably trigger bitflips with a single row opening in 13% of tested rows at 50°C[1]. Some rows in certain chips can be flipped with access times of under 10ms[2].

At more realistic row open times of 7.8 - 70us, there seems to be a 1/x relationship between row open time and number of activations required, they cumulative amount of time the row needs to be held open for to trigger a flip seems to remain fairly constant (around 50ms total from my very approximate estimations). Note that the attack needs to be executed in under 64 ms total, otherwise the automatic DRAM refresh will reset any progress made.

The authors demonstrate this attack with a userspace program that maps a 1 GB hugepage to be able to directly manipulate the lower 30 physical address bits[3], although they don't seem to provide the row open times they end up being able to achieve in practice.

The attack code itself: https://github.com/CMU-SAFARI/RowPress/blob/main/demonstrati...

Try adding the EasyList Cookie List[0] to your adblocker to block them all.

It's present in the uBlock Origin filter list settings under Annoyances but not enabled by default. HN readers may also find some of the other default disabled filter lists interesting such as the AdGuard URL Tracking Protection list which strips tracking parameters from URLs.

I'm not sure where your getting this from, a phone number is _optional_ for CSGO, adding one is said to improve your "trust factor"[0], theoretically improving your matchmaking experience.

I don't believe TF2 has any sort of phone number system that I'm aware of. If there is one, it doesn't seem to function very well given the bot invasion over the last few years.

I can't speak to dota 2 as I've never played it.
