aPoCoMiLogin··on Ask HN: Is Google deliberately breaking Firefox?
that issue is visible in any browser, the GCP console is really bad in some places. for example checking metrics can freeze chrome on a desktop with 7800x3d+64gb ram

how is that open source app is smaller but a lot of faster than the official app? never saw this app, thanks
aPoCoMiLogin··on Ask HN: How to handle a senior hire turning out to be junior?
at my $work we are doing hires in 2 phases, first is mostly talk, and second is "trial day". on the "trial day", the candidate gets simple task (with few requirements and optional bonus points), that we could manage to do in 1/2 or 1/3 time that the candidate gets. the task has to solve something similar that we were working on, so that we test how the candidate perform in real scenario.

in the past few years it worked quite nicely but that still is not bullet proof. and we had to refine our methodology further.

for example one candidate solved the task perfectly, but on the end of the "trial day" the candidate was unable to answer some of our questions regarding his code. so we think that he had access to the task details upfront, or someone else helped;

another example was with candidate that solved the task, answered our questions, but in the office was lacking everything that he presented to us in the "trial day". we suspect that the relative of the candidate helped here, as we found later that the relative has job in similar position in another company.

so the "trail day" is good way to test candidate, unless he has early access to the details of the task, or relative is helping with the task. it sorted a lot of candidates that were unable to follow the task details, or worse lacked team working skills

aPoCoMiLogin··on BenQ releases 3:2 aspect ratio 28 inch 4K+ monitor designed for programmers
if someone is looking for monitor, i can recommend the LG 28MQ780 [0], its 2x 2560x1440 stack on top of each other (2560x2880 in total), giving you 16:18 aspect ratio. i'm using one of these in portrait right and it's fantastic for coding.

aPoCoMiLogin··on Vanguard just went live and LoL players are claiming it's bricking their PCs
classic trolley dilemma. i'd do the same thing, if few % has issues, that can be fixed later, having whole industry that's creating and selling cheats, is just too big an issue to simply ignore.

in the grand schema, you'll lose few % of playerbase, in exchange you'll get much more happy customers, so in the end it will be a win.

aPoCoMiLogin··on Loading a trillion rows of weather data into TimescaleDB
things are changing recently in aws, but few years ago R-family instances had one of the fastest uplink to EBS. for example only the larges M4 instance (m4.16xlarge) has 10gbps uplink, versus R5b where it starts from 10gbps (for the lowest tier) and ends on 60gbps @ 260k IOPS. you can very easily choke EBS with DB.

EDIT: only newer C instances have comparable uplink to EBS, C5 or C4 (and some C6) starts from ~4.7gbps. just compare the EBS bandwidth column in https://aws.amazon.com/ec2/instance-types/

aPoCoMiLogin··on Do we need to store all that telemetry?
>At the scale of Netflix or Reddit it very well may make sense to only keep very limited CPU/memory stats on such a massive fleet.

read again what is his argument, that we don't need to store __any__ cpu/mem/storage metrics, other than "business metrics" (or later he crawled back to polling from time to time).

> Look, I have a different opinion as well, but the difference between you and me is I'm not resorting to personal attacks and instead discussing it on the merits.

maybe that's due to difference in culture/region, but i'm unaware where i've attacked him personally. i've just pointed out that what he's saying is to be expected by someone without experience/knowledge "in the field".

aPoCoMiLogin··on Do we need to store all that telemetry?
crossing fingers that the process that is polling the storage doesn't crash in the future, so you won't be left in the dark, as there is no metric stored, so you will never know when things will go down the drain.
aPoCoMiLogin··on Do we need to store all that telemetry?
> You question his competence. > He was answering that. > If instead of dismissing someone outright and question their competence, you had raised specific concerns, this would have been a more productive conversation

he first said that we don't need to monitor anything, just enable debugging when "business metrics" are failing, and then he changed his stance to "polling from time to time". that's just shows that his first take wasn't thoughtful, so I assumed that he never worked in "the field" or worked on smaller projects, as nobody that worked in bigger projects would say that "we don't need CPU/mem/hdd metrics". it's not like hes proposing something novel, that just ridiculous take that needs to be called out

aPoCoMiLogin··on Do we need to store all that telemetry?
> And they provide excellent credentials which you failed to check...

that's logical fallacy, you can work in any place on earth and still be wrong in the subject.

> You can't just weasel out of it by pretending like you didn't start the interaction by calling someone's expertise into question.

why? if his take is bad, then his job or experience doesn't change the outcome. i'm not an expert by any means, but things that hes saying just contradict everything that is standard practice and my own experience. based on that i'm able to say that he doesn't know what he's saying/proposing, and using his "excellent credentials" just make things worse, as it shows that he doesn't have an argument, just wishful thinking

aPoCoMiLogin··on Do we need to store all that telemetry?
I think that you are confusing real-time metrics, streamed with very high precision (below 1s) and metrics that are simply polled every N time (most use-cases).

real-time, high precision metrics aren't necessary. when you say that you don't need metrics and then say that you can poll metrics periodically, you are contradicting yourself.

aPoCoMiLogin··on Do we need to store all that telemetry?
where you worked doesn't matter to me very much, when what are you saying contradicts what you probably did ("experience in large scale systems"), also it sounds like argument from authority.

not having cpu/mem/hdd metrics is just plain bogus and sounds like fantasy world, where everything works like we expect it to work, and there is no bugs at all. ridiculous

aPoCoMiLogin··on Do we need to store all that telemetry?
when storage is full, and you don't know about that, you can't release anything to enable the logs in first place.
aPoCoMiLogin··on Do we need to store all that telemetry?
if you don't have metrics for cpu/memory/storage how do you know when to scale the app, or when you are at limit of the storage? i feel like you have never touched servers/backend in anything more than simple projects (or at all). with full storage/memory there could be an issue that you won't be able to ssh to the server, so it speaks about your knowledge in this matter.

collecting user-identified telemetry is debatable (depends on the case), but not collecting anything at all is just plain stupid.

aPoCoMiLogin··on Bruno: Fast and Git-friendly open-source API client (Postman alternative)
the extensions and ability to write your own extensions, or chain request/response values is crazy. when i've switched to linux box from macos last year, paw.cloud (rapidapi) was one of few stoppers for me, that good of a software it is. also not to mention the integration with keychain for credentials encryption was nice.

postman is really bad, nobody should use it. same goes for similar solutions, even this one.

aPoCoMiLogin··on Why desktop Linux is finally growing in popularity
you can't use whatever external monitor you have, because you need specific dpi ratio to make scaling works, otherwise blurry screen, because apple only do things for their hardware.

you can't charge keyboard/trackpad (and probably a lot of other stuff) with (some, or most) non-apple blessed chargers. i was unable to charge the trackpad fully, even in a week; had it constantly connected to charger, couldn't connect to mbp as the mbp had only usb-c ports. after few warranty replacements, someone asked me what charger i'm using, so i've tested the usb-c -> usb-a adapter and connected the trackpad/keyboard to the mbp. it charged fully, and the battery didn't died in few hours. after that i've returned/give away all apple-made accessories. fuck that hostility

aPoCoMiLogin··on Starlink's laser system is beaming 42 petabytes of data per day
so you are asking if the traffic is additionally encrypted? i don't think that additional encryption is needed, like your ISP doesn't additionally encrypt your TLS encrypted traffic, that would be waste of resources
aPoCoMiLogin··on Ask HN: Are height adjustable desks worth it?
that sounds like really cheap desk. i've got adjustable desk mostly because the one that i've seen in ikea etc were the most stable desks that there were available.

the unlimited plan was phased 7 months ago [0] so got few notices, with the final one 7 days before termination. so the guy with 250tb of data neglected that for half a year and now is surprised.

your data can be public without your consent, what then ?
aPoCoMiLogin··on Ask HN: To what extent have digital payments replaced cash in your country?
never heard of such fee, 40% sounds crazy, like impossible. from what I know living in Poland for my whole life, the fees aren't pushed by ATMs, but banks itself, so you should check fees in your bank, which sounds like foreign bank, so it might be that the exchange was that high or something.
aPoCoMiLogin··on Apple's Scary Fast event could spell the end of its Lightning port
wait till you find out that the lightning needs to be connected to apple device/charger to fully charge trackpad/keyboard.

i didn't know that, returned trackpad 2 times, because it didn't fully charge and the battery drained like in 1-2 days of use. when i found out that it needs to be "blessed by apple" source of power, i've returned all the apple peripherals that i've had, so i'm not going to participate in this stupid ass fuckery.

aPoCoMiLogin··on The killer features of the Steam Deck
had a lot of issues with magic keyboard & trackpad, plenty of times they just disconnected, not to mention apple still doesn't show the battery level for a lot of BT devices.

after switching to linux, BT has the same issues just multiplied because now there is N vendors with each having their own quirks.

aPoCoMiLogin··on The killer features of the Steam Deck
I was just reading your comment when my BT headphones disconnected from the USB BT dongle and had to restart the BT service, what a timing haha
