rasz_pl··on What the death of the CRT display technology means for classic arcade machines
Obviously not, there is no memory inside the glass, and bandwidth is limited. LCD screens still scan in.

The difference is LCD keeps picture until told otherwise, whole picture is emitting light. CRT has limited phosphor persistence, there is only one point/pixel being lit at any given time.

This was common in all Eastern Bloc countries. In Poland under Russian occupation UB/SB https://en.wikipedia.org/wiki/Służba_Bezpieczeństwa "secret police responsible for internal and external intelligence and counterintelligence to fight underground movements and the influence of the Catholic Church" would send its agents to schools to befriend children and try to get them to rat on the parents.

You mean giving control back to the users of your software? Google doesnt play like that. Motership knows best!

You were admired the same way people admire iphones or European supercars. Great to have a token white guy for random photo op, but dont count on getting real job or any kind of power/control (like being able to create a company etc.)

what air ducts? this is a mac we are talking about, not a thinkpad. There are thin inadequate slits in the case, they are the reason any cpu load results in 80'C, and every discrete GPU mac dies to be eventually grudgingly covered by some small time window "we care enough to not get sued" recall program.

Those prices match Intel promotions and bonus gifts Intel ordinarily offers to big distributors for pushing hi-end product (CPU and Chipsets). There is nothing suggesting Microcenter is running a loss on this, they might have a very thin margin, or even sell at 0 and only count Intel gifts as a potential profits (Intel will give distributors gifts like "free" SSDs for selling X number of expensive parts). Its all in the spirit of tactics that were killing AMD in ~2002 and lead to Intels monopoly trial, just made a little more subtle this time.

Quicksync is a marketing bullet point. Nobody sane uses this crap because quality is abysmal. Its bad for streamers (they usually run second PC just for stream compression), and bad for archiving video(quality again).

Water utility company is a epitome of dumb pipes, but they will cut off bad supply instead of pumping poison while cutting out customers.

I can install hardware backdoor in a macbook in under 3 minutes (with prep obviously).

Even you could do it https://www.youtube.com/watch?v=qGPGOoJn54E hint: there are internal USB buses in the macbook, you can hijack one for something like rubberducky +management circuity to trigger only when laptop is powered on for a longer period of time but not touched (no imu/keyboard/touch events/dimmed screen).

You cant restore SSDs. I would assume Googlers are rolling SATA SSDs, if not M.2 PCIE ones.

What Google could be doing is remote logging on the laptops - logs uploaded to ze cloud every time you connect to the mothership. Plugging in USB drive leaves trace with USB ID, volume information etc. Windows also logs this and more http://www.forensicswiki.org/wiki/USB_History_Viewing

Protip: to exfiltrate data with minimal trace your best bet is taking out the drive and reading it in another computer (using write blocker for best effect), this can still be traced if someone is logging SMART written/read data (I am, but Im paranoid), not all HDD/SSD vendors provide this info. Second best is booting from USB drive so the original OS never sees the plug/unplug event in the first place, I have no idea about current state of UEFI/AMT logging going on tho.

Disclaimer: I used to do forensics.

rasz_pl··on AMD Ryzen price and release date revealed
Its still better than nothing. AMD management is dysfunctional, they treat engineering as a cost and were cutting it badly during K9-K10 era.
rasz_pl··on AMD Ryzen price and release date revealed
AMD has a history of having dysfunctional R&D:

386DX - copied Intel design verbatim (1:1 microcode). Got sued, won only because Intel had multiple source agreements with IBM.

K6 - purchased NexGen. Designed 100% by outsiders.

K7 - once again hired somebody else's engineers. This time almost whole DEC Alpha design team.

K8 - DEC people had some more steam left in them.

K9-Zen period - no more companies to take over and claim credit for their designs, add terrible management bleeding engineering talent while burning money on stupid ideas like Seamicro = in house garbage with 50% Intel IPC.

Zen - finally managed to rehire competent ex DEC engineer Jim Keller after his successful career at Apple.

rasz_pl··on AMD Ryzen price and release date revealed
I have to wonder if the AMDs console win for the current generation gave them this badly needed R&D to reach decent TDP.
rasz_pl··on AMD Ryzen price and release date revealed
They might play dirty games instead (again). Intel loves incentivising its distributors with bonuses and deal combos. Sell top Intel CPU + expensive motherboard with top Intel chipset = receive free Intel SSD etc. Of course distributors are free to do what they like with those rewards, consumers almost never even know about it = bigger hidden margins for pushing hiend models.

rasz_pl··on Bash and Windows Subsystem for Linux Demo [video]
Even if they optimize to the point of native Windows speed it will still be slower than native Linux. Its a well known fact some heavy IO programs run faster under Wine than native.

is it really? last time I read tests WSL was slower than VMs

Yeah, I automatically went into what I know :/ Its impossible to route manually there days, which doesnt mean automagic tools are even remotely good, same goes for synthesis (fpga).
