altmind··on Updating the Git protocol for SHA-256
because the speed is not the only concern. also, sha2 is already hardware accelerated, and may still be faster than the rest of the hashes.
altmind··on Why did post-8008 CPUs not keep the on-chip stack idea?
low-end PIC8 micro-controllers still use tiny hardware-based stack, these are still sold and widely used.
altmind··on Serverless LAMP stack
Its never "serverless". Its compute outsourcing.
altmind··on GitHub is working on renaming default branch from “master”
`Out of memory: Kill process 4447 (python) score 519 or sacrifice child`
altmind··on GitHub is working on renaming default branch from “master”
But "master" in git is not about master/slave relationship, its about a "master copy"?
altmind··on In defence of swap: common misconceptions
While I find the question puzzling, i find the description lacking. The whole explanation of anon maps is redundant, since the behavior of anon maps seems to be the same as the behavior of plain memory - its evicted on low memory conditions with LRU behavior and there is no anon maps specifics mentioned.

To recap: swap makes anon memory pages reclaimable, by offloading it to disk. This does not explain anything. Its basically "swap allows anon maps to be swapped"; so what?

>> You need to opportunistically handle the situation yourself before ever thinking about the OOM killer.

Or, just rely on OOM killer, minimal swap(so the application dont agony in low memory conditions) and restart policies. There are no reason to do the kernel work handling memory over-commit.

altmind··on Warren Buffett’s Berkshire dumps most of Goldman Sachs stake
> Many in finance think we're headed for deflation.

More in the firnance think we're headed for inflation. as soon as money leave equities/deriv markets.

altmind··on Building a Gaming PC for 100$: Is It Possible?
This topic is not new, there are a lot of youtube videos about that(and done in exactly same manner - repurposing used office pc with a new video card). The resulting machine is not well-thought, why buying SFF case, if your video card does not fit?

altmind··on Gitlab.com Is Moving to 13.0
as an admin and a user, im totally happy with gitlab. its a easy enough to administer, its reasonably priced even for a small company, and they dont try to push their "cloud offerings".
altmind··on How Much Is a Human Life Worth?
In monetary value, there's couple estimates in Wikipedia. I've heard that for airplane designers, they assume the value of life at 10M for safety features design purposes.

altmind··on Ask HN: Is your company sticking to on-premise servers? Why?
to control the costs. after the original purchase, the MRC is a fixed cost for hosting and for the network access. also, for the total control - the network, io, cpu performance does not change randomly. with better predictability our IT team can give more precise SLA.

we're not 100% on-prem, but aws, gcloud and azure are the worst examples of 3rd party hosting - unpredictable and with complicated billing. we're considering the alternatives to big 3 for the "cloud hosting"

altmind··on [dead]
tldr: Stimulus package will spark the inflation. QE did not spark the infrlation, but the stimulus(wich will 95% will be spend on goods/services) will. (well, ofc the money going back to economy boost inflation more than money not spent yet. but thats not the point)

its a poor article boasting a flashy headline.

altmind··on Apple aims to sell Macs with its own chips starting in 2021
So shipping bytecode is not mandatory? Interesting, what % of developers are actually sending the bytecode in, then.
altmind··on Apple aims to sell Macs with its own chips starting in 2021
So does it mean Apple users will need to migrate to ARM builds for their software? It took smth around 3 years with powerpc->x86 migration.
altmind··on Ask HN: Successful one-person online businesses?
hmm. is it dracula or is it darcula theme? intellij idea is pretty persistent calling it darcula
altmind··on Ask HN: Programs that wasted you 100 hours?
I'm surprised no one mentioned openstack. I never deployed it, but by mere reading its deployment docs, its going to be a mess in production and its not doable by a solo dev. Anybody care to correct me?
altmind··on Scaleway is retiring its ARM instances
>> the physical servers hosting them are indeed randomly affected by several stability issues

this may cast a shadow on ARM64 servers credibility.

they used to design their first generation of arm servers in-house. it looked like a blade server with slottable cpu(or was it the whole system on a micro-board?). check the video from 2014(at the end) for some glimple on a physical machine https://blog.scaleway.com/2014/online-labs-public-preview/?f...

altmind··on Ask HN: Programs that wasted you 100 hours?
Docker. Images without command line tools(best practice!) Obscure init systems. Unmountable overlay FSes. Dangling images eating all the disk, not removable by prune. Root permissions everywhere and general necessity to debug images way too often. and looong checkout times for every image update.
altmind··on Ask HN: Programs that saved you 100 hours?
Maybe not 100hrs, but ~40 Regex Buddy $40. regex tester, debugger and in a lesser extent, regex applier.
altmind··on Linux Bash vs. Windows PowerShell
Have anyone replaced *sh with powershell on linux for scripting?
altmind··on Show HN: Dashboard for tracking insider trading at S&P 500 companies

altmind··on Private equity is a scam?
This seems like criticism of leveraged buyouts, than criticism of PE. Many good companies were driven into bankruptcies when purchased for their own money and there were a lot of talks about Bain Capital in 2012 pres elections cycle. Actually, i was expecting a thread about how PE scams their investors, not how buyouts are destroying busineses
altmind··on How does Monzo keep 1,600 microservices spinning? Go, clean code, strong team
Its a weird to flex about how complicated is the system that you created. Creating simple systems is harder.
altmind··on Mobile CPUs and the Performance Inequality Gap
specint2006 shows that A13 outperforms desktop ryzen 3900x. 5W vs 105W. 6 cores vs 12 cores. something is wrong with numbers here.
altmind··on Mobile CPUs and the Performance Inequality Gap
geekbench have unreliable perfromance stats that've been favoring iphone for a looong while.

check your conclusions - 90% of articles with rocking iphone performance cite geekbench.

altmind··on Warren Buffett has the cash to buy Tesla, Starbucks, or McDonald's
... but is probably smart enough to buy other 10% of our lives. look at this and tell me this man got no 20/20 forward vision https://news.ycombinator.com/item?id=22401875
altmind··on Delivery workers are keeping California fed. They say no one’s keeping them safe
with the food-industry people cannot afford healthcare for themselves and made to work, to get the means to live, I'm very scared to order anything from any prepared-food establishments. the chances of getting contaminated food are incredibly high, esp if you order smth not thermally processed.
altmind··on Minimalist Hyperscale Servers for the Rest of Us
"Minimalist servers" dont mention the depth of their 1U offerings. they wont even fit in your normal rack, yet they are "minimalist".
altmind··on US now nation with most coronavirus cases
> It seems this virus propagates much better in cold weather.

Its the first time i hear such claim.

altmind··on Firefox for a Better Web offering privacy and faster access to great content
Can mozilla do something with forceful pocket integration? I know that mozilla straight off bought pocket, but every day I use the browser, I'm reminded of they decided to profit off their users, as well as the moments when "google.com" was not even a selectable choice for a search engine, for their political game.
