mazurnification··on Twitter kills its San Francisco headquarters, will relocate to South Bay
If I can try to explain it - it is overcorrection from times when Tesla and SpaceX were cool with appealing mission places to work on. Bcs of that they could get away with smaller salaries too (although Tesla meteoric rise in value compensate it if you got options as I understand it).
mazurnification··on TSMC unveils 1.6nm process technology with backside power delivery
It will be 18A first.
mazurnification··on TSMC unveils 1.6nm process technology with backside power delivery
There are certain trade offs when designing process. TSMC researched with partners how AI and HPC (high performance computing) chips most likely will look like and adjusted process accordingly.

In fact this is big deal as until recently the processes were more tailored toward mobile application (that is were trading some switching performance for lower power consumption). Look like we are back in 2000s when speed/density is again more important than power consumption.

mazurnification··on EU opens proceedings against X over efforts to combat information manipulation
I am true admirer of US style free speech regulations, but as EU citizen I agree with this action though. Why? Because Twitter already cave in (and rather easily I must say) to the Turkey request for pre election lets call it "special moderation".

So the solution is either heavy anti-monopoly regulation requiring splitting of Twitter to several competing entities (though preferable, probably not feasible w/o US agreeing and enforcing it) or less than ideal some kind of content regulation. Otherwise we are giving away ability to speak and censor to autocrats (again Turkey) while doing nothing. Kind of stupid. If it is already censored and regulated (again Turkey) I do not see big deal if it regulated according UE rules.

mazurnification··on Intel, Samsung, and TSMC Demo 3D-Stacked Transistors
Good question - but it would have to be a one of the kind that decrease latency not the one that decrease bandwidth. Maybe there is a way to achieve such.
mazurnification··on Pico Serial Bootloader (2021)
Yes RO2040 is very good in that regard. It is often hard to gauge from processor clock how fast it will toggle its pins. Example PI4 - I do not think I was able to get more than 5MHz from its GPIOs and this is 4x GHz class processor.
mazurnification··on Tell HN: Twitter switched temporarily to rate limited mode
After hitting rate limit I cannot even read my own tweets (Profile->Tweets). I find it hilarious.

One more thing - it look like rate limit is per client. When hit on mobile app I could normally use TT on web interface till fresh allowance was exhausted. Which did not lasted that long, too.

mazurnification··on PC keyboard hides an interesting secret
Do you have source for the claims? I doubt especially of free parts. As of rumors I have heard about Broadcom it is extremely "capitalistic" company. If you move a lot of chips price can go down a lot (due the fact that NRE divides to more units). The cost of chip manufacturing alone is not that big - example Apple A14 bionic chip was estimated to cost 17$ to manufacture [0] and it should be waaaaay more expensive than anything in RPI.

mazurnification··on Tiny Tapeout: From idea to chip design in minutes!
Raspberry Pi has microcontroller that may work for you (RP2040) it has programmable IO thingy that is quite impressive). Anyway regarding small FPGAs/CPLDs - i am passively keeping eye on small/inexpensive parts - and as far as I know it is not field abound with options (Cypress PSOC, LAttice iCE40, small CPLD from Altera(Intel)/Xilinx(AMD)). Just learned about GreenPAK (Dialog and now Renesas) and I am quite thrilled. Do not know how it could fly under my radar.
mazurnification··on For the first time, the Fed is losing money
FED chairman is elected by POTUS and confirmed by Senate. With 4y term. That is your say - it is indirect but most (all?) things in modern democracies are indirect. Obviously on top of that there are more soft influences - such as public opinion.
mazurnification··on For the first time, the Fed is losing money
Then compare currency stability from democracies to autocracies. Turkey versus Germany for example.

edit: missing word

mazurnification··on For the first time, the Fed is losing money
I am one of the guys that says money do not have intrinsic value. Or more precisely it "value" is due the fact that they enable trade and enable time shifting the trade (That is store value). My mental analogy is that money are lubricant. Too little everything grinds to a halt (deflation crisis) or too much and it burst seals and spills everywhere (inflation crisis). So there is clear signal to the population that something is wrong with money. Then if you live in democracy you have say on the policy. That is why democracies tend to have more stable currencies compared to autocracies. And lack of this stabilising feedback loop is main critique of cryptocurrencies. Note how unstable value of bitcoin is - it goes from massive inflation to deflation and back very often (single years time spans).
mazurnification··on One Year into the War in Ukraine
But Transnistria has between 360k - 475k ppl (from Wikipedia). Plus everybody want Romanian passport (which is not that hard to get if you are Moldovan) - due to UE free movement ...
mazurnification··on How Twitter moderated the Covid debate
Then why dumb pipe should be worth 44B$? And you are contradicting yourself - if something is facilitate debate (as opposed to enable) then it is not dumb.
mazurnification··on Paul Graham is leaving Twitter for now
Honest question. What is probability that Elon will run poll and revert policy change? (My pick 80%)
mazurnification··on Promotion of alternative social platforms policy
My sentiment exactly - just in time for holiday brake "project".
mazurnification··on The Death of SRAM?
Up to this point being firmly in the camp that Moore's law is not dead - this is first data point that convincing enough for me to reconsider my stance. The problem is not that SRAM is important or not. SRAM cell is basically one of the simplest circuit actually doing something useful, where most things important for actual design are in play (not only transistors size, but also its parameters, parastics, manufacturability etc). Also since it is so simple and important circuit it is hard to argue it was not optimized to the moon and beyond. If this do not scale - girl we are in trouble.

) Although signs of slow down were plenty beforehand if you squint your eyes it was possible to attribute it to Intel dropping ball and rest of industry catching up its 1.5 generation lead. (Industry converging back to long term trend).

mazurnification··on Why Twitter didn’t go down: From a real Twitter SRE
Agree, I wonder how much it is thought through strategy and how much is just "natural" style applied indiscriminately. I think one more important part is that he has money/resources to be able to make mistakes without bankrupting and stubbornness to plough thru even when things go wrong.
mazurnification··on “just put Twitter in the cloud” we tried that- $300M monthly
There is nothing simple in data moving. Problem is that it can be abstracted away so you do not have to worry about it. Out of sight out of mind. Example - majority of the CPU area is devoted to data moving problem (cache, branch prediction, out of order execution, register renaming). The same is happening on other levels of the stack (OS, network and so on).
mazurnification··on Elon Musk owns Twitter: The story so far
Source? Surprisingly hard to find in quick search - drowned by fluff articles.
mazurnification··on Coal Prices Rising Exponentially
"Poland is burning more coal than it was in the 90s"

Not true, coal usage[1]: 1990 -> 237Mt, 2016 -> 149Mt

As a tangent, I was shocked that Poland CO2 emission per capita is lower than one of Norway [2]: Norway 9.4t (2018), Poland 8.8t (2018)
