concerned_user··on Transfer files over an Ethernet patch cable
Back in the day you needed a modified cable for this with RX/TX swapped on one end but nowadays probably all nic chips have auto-detect so you can take a normal patch cable and do it.
concerned_user··on The August 17 outage
If page has 15 requests and needs data from all of them to work correctly, then with 20% failure rate you are suddenly close to 100% non-functional page from the user perspective.
concerned_user··on Offline card payments should be possible no later than 1 July 2026
There is no rule that there has to be a single payment per authorization, if you read for example mastercard API https://in.gateway.mastercard.com/api/documentation/integrat... it says you can partially capture, you can extend authorization. So for all you know when you buy at amazon it just updates the authorization and charges you later but keeps authorization going and amazon might just check if they have auth token for your card and if they do system allows you to continue and to you it seems instant.
concerned_user··on How to handle people dismissing io_uring as insecure?
This is only true if people stick to a version of a language and don't upgrade.

If you upgrade then, for example, you can't run all of your PHP 5 code in PHP 8, most of it you can but you will have to change the parts that are broken, which are the areas that are repaired in PHP 8.

Same goes for other languages like C# or Python

concerned_user··on Bunker Busters probably failed to penetrate Iranian concrete
They are only sensitive to vibration while running, if turned off then just checks and re-calibration needed before turning them on again.
concerned_user··on We Tested 7 Languages Under Extreme Load and Only One Didn't Crash
Is that just sloppiness on their part or is it LLM chat bots being used with a prompt "hey give me current versions of these languages" without verifying the result?
concerned_user··on We Tested 7 Languages Under Extreme Load and Only One Didn't Crash
I think by crash they mean program stopping execution and being unable to continue, so by that metric Erlang didn't fully crash.

Erlang is designed with a mechanism that makes it easy for external processes to monitor for crashes (or hardware failures), rather than an in-process mechanism like exception handling used in many other programming languages.

Erlang was designed with the aim of improving the development of telephony applications.

The Erlang runtime system provides strict process isolation between Erlang processes (this includes data and garbage collection, separated individually by each Erlang process) and transparent communication between processes on different Erlang nodes (on different hosts).

The "let it crash" philosophy prefers that a process be completely restarted rather than trying to recover from a serious failure. Though it still requires handling of errors, this philosophy results in less code devoted to defensive programming where error-handling code is highly contextual and specific.

concerned_user··on Finland announces migration of its rail network to international gauge
It is ongoing project but there doesn't seem to me enough financing, the money that EU allocates only cover about half of the required budget so they are looking for investors.
concerned_user··on Finland announces migration of its rail network to international gauge
Correct it is a new rail line not an alteration of existing tracks, but it goes into some existing and new (mostly cargo) stations so some stations will have both gauges of track.
concerned_user··on For Delivery Workers in Latin America, Affordable E-Bikes Are a Superpower
I don't think it is fair to compare Netherlands to other countries like UK or France because Netherlands has a well established culture around bikes and bike lane infrastructure is one of the best in the world, so it will be the last country that will have any issues because of e-bikes.
concerned_user··on Zelensky leaves White House after angry meeting
They already did, about a month ago.
concerned_user··on Marine pilot loses command after ejecting from F-35B that kept flying
> I don't know if switching modes like he did was standard procedure and if the resulting failure was unusual or not.

Pilot switched mode back to normal flight because it was the switch to landing mode is what caused his HUD and PFD to turn off in the first place.

concerned_user··on Why the CrowdStrike bug hit banks hard
Yes it is a driver which is signed and tested by Microsoft. Driver allows to run arbitrary unsigned code. Why is that allowed?
concerned_user··on New Recovery Tool to help with CrowdStrike issue impacting Windows endpoints
You are right Microsoft are not checking the 3rd party code itself they are only running a lot of tests on the compiled code.

There is a recent video now from a former Microsoft employee where he explains that those drivers that get WHQL certification are ran on test machines in stress conditions for some time, or at least that is how it used to be when he worked there.

Since that process is probably quite slow to be able to push update within a couple hours Crowdstrike just bypassed the QA testing by injecting their own data files into the driver.

concerned_user··on New Recovery Tool to help with CrowdStrike issue impacting Windows endpoints
WHQL signifies it is tested and that driver is WHQL certified.

I also think Microsoft should be responsible, they gave the keys to sign the kernel driver so I expect that driver to at least be subject to regular testing and scrutiny not just when initial release was made.
concerned_user··on The tiny chip that powers Montreal subway tickets
It depends if the tickets are trip based or time based, for time based system you don't always need validator.

I have visited Prague in 2019 and their subway had no barriers, ticket machines were tucked somewhere in the corner so that I had to actively look around. Interestingly the metal poles where sticking out of the floor up to waist height with a spacing like that they used to have validators on them before.

Since I had a 3 day ticket and I validated it on the bus when going from the airport I didn't need a validator. Their trams and buses had validators in usual places, so subway probably has them too but not in an obvious place or the ticket machines already print ticket with time on it so you don't need to validate it.

concerned_user··on Helldivers 2 Removed from Purchase on Steam in over 150 Countries
There is a screenshot of an email that someone from Ukraine sent to Sony support and their response was that you can create an account using PS5 but not from a PC.
concerned_user··on London Drugs closes stores until further notice due to cyberattack
Here in europe it is a government database where all the clinics and pharmacies are connected to, so doctor essentially creates a record in the database.

When you visit pharmacy they ask for id and enter your id number system shows them all your active prescriptions and past ones as well, which sometimes helps when your prescription is not renewed for some reason they can give you a week supply while you sort it out.

concerned_user··on London Drugs closes stores until further notice due to cyberattack
Before internet was commonplace you would have to go to a doctor and get a paper prescription which was sometimes done on a paper with watermarks and verification was that this piece of paper has a stamp or a seal on it and doctor's signature.

There were more forgeries with paper prescription than there is with online system.

concerned_user··on Microsoft suggests command line fiddling to get Windows 10 update installed
I can only see it using dism to apply the patch but there is no commands to manipulate partition size so if the cause is lack of free space it will fail same as update did.
concerned_user··on The UX of delivering parcels
Here in europe that is exactly what I see, a store will show me tracking number and if I click on it carrier website says - "Label printed" so you know it is not picked up yet. DPD carrier does it like that.
concerned_user··on 23andMe updates their TOS to force binding arbitration
You are correct, I can not find where arbitration is forbidden in the directive also it is quite the opposite.

I think in this particular case we are talking about Directive 2011/83/EU of the European Parliament and of the Council on consumer rights.

Article 6(1)

(t) where applicable, the possibility of having recourse to an out-of-court complaint and redress mechanism, to which the trader is subject, and the methods for having access to it.

concerned_user··on There are now two types of PayPal dollars, and one is better than the other
I think it depends on the country your business is in (i.e. local laws and regulations) and what is your transaction volume is through Paypal, if you have large transaction volume I am pretty sure you will get better conditions.

Our company has very low volume through Paypal, we only provide it as a convenience and we had to limit payment amount due to fraud we had in the past, so these are likely the worst conditions you can possibly get.

concerned_user··on There are now two types of PayPal dollars, and one is better than the other
If you accept payments via Paypal you can't withdraw money for 21 days, at least that is the case in the company I work for. Explanation is that in case a dispute will be issued so that they can refund, so my guess is large proportion of those funds is such payments being held.
concerned_user··on Discord’s username change is causing discord
My guess is that they look at application analytics what features are used and how often and see that in 40% of cases the send friend request form is not being submitted and just closed.
concerned_user··on YouTube CEO Susan Wojcicki is stepping down
> Sponsors don't pay a fixed amount to creators. They pay for (estimated) views.

This can't be right, I've seen many videos from creators that say the opposite, it is a fixed amount per contract which can be one or more videos. Maybe it is different with creators that have more than 1M subscribers.

concerned_user··on Stripe increases price for business in the European Economic Area
In many online shops in EU you can see "Administrative fee" if your order is too small for example. So while companies are not allowed to do "Credit card fee" they still do it indirectly in one way or another, those that don't impose extra fee usually have higher delivery fee.
concerned_user··on Send a text message about Ukraine to a random Russian mobile number
Yesterday, I have read in russian independent newspaper in a live feed that woman was arrested and charged with organizing a protest, after posting on Twitter "Let's go and take a walk on the main square".

This can of course be fake, but if true, then having SMS like that could lead to being questioned in the very least.

If you want to encourage the protesters and give them words of support then text of the message is wrong, those people already know that press is twisting the facts. They do read foreign media, while they still can, but Russia has been conducting exercises on cutting their internet segment from the rest of the internet since 2018, so at any moment they can just flip the switch.

You are correct the broadcasts were not wrong, people were eager for that information, but it was discussed mostly in private and with close friends only.

Other issue is that SMS spam is really bad in Russia so likelihood of that message being taken seriously is quite small, especially with official media saying that West is waging information war. So message with content about mainstream media lying received by a supporter would probably not have the impact you would imagine. Bringing some facts that would cause people to investigate further would go a lot better in my opinion.

Those are state-run polling agencies, there is no recent independent polls as far as I am aware.
