zeroflow··on Why are air combat kills so rare? (2017)
These are only assumptions from what I've read and heard.

But from what I know, this also comes from the logistics standpoint. If you need a prescription of any kind to "function normal", they would need to supply that prescription anywhere anytime. I would assume the same with wisdom teeth. The risk of getting any problems during service are not worth taking.

So yeah, there is a difference between "I need this for functioning normally" versus "Take this in case of an emergency"

zeroflow··on Toyota owners have to pay $8/month to keep using their key fob for remote start
The topic with the TVs is going to be a problem for me in a few years. My current TV is from 2013 - it may have some years to go, but at some point, it will fail.

I've had a short look at the market, and all the "good" brands (Samsung, LG, Sony) show horrific ads. It looks like the cheap brands simply sell your data. Then there are some local brands, which sell non-TV TV's (no tuner, there's a tax on that). They don't have any smarts at all, but the one I've seen had terrible picture quality

zeroflow··on Toyota owners have to pay $8/month to keep using their key fob for remote start
That is just bullshit.

A $8/mo charge for a app based remote start? I could live with that. Servers need power, the app needs updates etc.

A $8/mo charge for something which does not incur costs for Toyota? Hell no.

It seems like bit by bit - every single industry is going down a fucked up route. TVs with built in ads? Cars with pay-by-month features? DRM locked coffee machines? I really hope, there is some sort of evil-bullshit-corp ranking homepage.

zeroflow··on E-Shotgun
I would not consider this a self defense weapon. This will probably just irritate the attacker for a second.

Advertising this for self-defense is rather reckless, considering that people may rely on that.

zeroflow··on E-Shotgun
I REALLY doubt the "Good stopping effect". That's the same as the flashlights with "intruder stopping" strobe.

They claim 16J. Well, a typical - Germany Legal - Airsoft gun has 7.5J, so we're talking about toy-level of energy.

Now, looking at some 9mm ammo, you have around 500-570J depending on type - Ball vs. Hollow Point.

Yeah, it's very clear to me, what I want to use if I have to defend myself.

zeroflow··on Playstation 5 root keys obtained
Well, If you look at both the PS5 and XBox One X, both of them are running customized AMD SoC's. But basically, that's just a AMD APU.

If my memory serves me correctly, the PS3 for comparison had a custom Cell CPU which was used for supercomputer clusters. https://en.wikipedia.org/wiki/PlayStation_3_cluster So they must have had some kind of edge compared to normal PCs.

zeroflow··on Node-RED: Low-code programming for event-driven applications
I can on reply from the perspective of a multi-year user:

It is primarily functional programming. This means, you have an input, that is processed through blocks (functions) and does some things.

This is GREAT for things similar to IFTTT (If this then that) applications. E.g. you receive a datagramm via MQTT, and then format it, add some info, and upload it into influxdb.

You can also easily add a small dashboard with some buttons and labels for easy home automation.

What needs some working around with context store are side effects, or persistance. I have two examples that can be worked around, but are rather hacky:

1) Reading a list from a homepage, and only sending updates for new items. This is the prime example for context - you save a list of seen items in the context of the function node, so the next invocation can filter out the existing ones

2) Using a switch in the dashboard for selecting between automatic and manual mode. E.g. I want to have my rack fans controlled by the temperature, but with an override to set it manually. This needs a bit more hacking with context where you have two flows into one node, and you have to set the internal state of the context depending on the override button.

zeroflow··on A USB Fan Controller that now works under Linux
There is the mention of a server grade fan control in the article, and it looks like this is a workstation / server board.

I've seen the sockets on those boards being "90° off" in comparison to normal AM4 / 1150 / 1200 Socket motherboards which lead to those orientations.

zeroflow··on We Test PCIe 4.0 Storage: The AnandTech 2021 SSD Benchmark Suite
PCIe slots come either from the CPU or the Chipset.

Typically, there are 16 lanes used per GPU and 4 per M.2 SSD.

With older CPUs, you had to either reduce the lanes assigned to the GPU to connect an SSD to the CPU, or go through the chipset.

With newer CPUs (newest intel or AMD Zen), the CPU provides 20 Lanes (16+4) for general use and in the case of AMD, 4 additional lanes for the chipset.

If you want more lanes connected directly to the CPU, you have to go to HEDT or Server Chips with up to 128 lanes available.

See this article for a typical block diagram of a AM4 system.

https://www.guru3d.com/news-story/amd-ryzen-3000-new-block-d...

Here you see, there are 1x16 / 2x8 lanes for GPU, and 4x PCIe/SATA combo ports from the CPU which can be used for connectivity.

More lanes can be provided by the PCH (Chipset).

Another example is in this artice by anandtech, which even lists the slots explicitly in the block diagram. https://www.anandtech.com/show/14657/the-asus-pro-ws-x570ace...

zeroflow··on Wehe – Check Your ISP for Net Neutrality Violations
> Mitigate the free rider problem(s), make the system fair.

Which free rider problem? The customer pays the ISP for access to the internet.

I understand that the ISP would like to double-dip on this deal. But I regard this as wrong.

zeroflow··on Show HN: Learn Regular Expressions with simple, interactive exercises
If this is your site, my feedback is, to have a more clear cut destinction between the explaination and the task at hand.
zeroflow··on Teensy 4.1 Development Board
No, it would be performance - for example regarding clock speed and RAM size.
zeroflow··on A detailed look at the router provided by my ISP
Sadly I could not, since the ISP is defining the router as the endpoint of it's network so there is no freedom to choose different models.
zeroflow··on A detailed look at the router provided by my ISP
...and that's why my ISPs router is running in modem mode with a non-ISP-controlled router from Ubiquiti behind it - which I may replace with a pfSense box in the future.

I'm pretty happy that my cable ISP is allowing this mode so I don't have to double-NAT in my setup.

zeroflow··on Driver 'blows up' car with 'excessive' use of air freshener
Am I the only one thinking that this was no "excessive air freshener use" but more like someone huffing flammable gasses?
zeroflow··on German politicans doxxed, massive leak of private information
Sometimes the people in charge fuck up?

They're running a streak of fuck-ups and while different parties run different ideas, I want none of the current politicians running a country.

The problem is, that there is no "sack the heads of all parties and start new without those problematic persons so we can get a new start" option to vote for.

But yes, the typical person does not care...

On the other hand, the government will always stay them. They purely live off work others do. They have no incentive to improve since they do not need to generate income, they simply "take" what they need from the rest of the population.

Any kind of streamlining or efficiency improvement will just kill jobs of their political buddies.

zeroflow··on Slack closes account of an Iranian user living in Canada
As bad as it may sound, but from what I can read in the tweets, he did violate the sanctions by using slack while being in iran.

Well, that is called breaking the law and I fully understand why slack terminated his account when he broke the law and violated their terms of service.

For example, other services or tools (like cisco anyconnect) clearly state, that you are not allowed to use them when in embargoed contries.

zeroflow··on NIST Random Beacon
What would be the typical usecase for this beacon?

The first usecase I could think of would be a warning canary that signs the data of the beacon akin to the plot in movies where someone holds up today's newspaper.

The 2nd would as said on the page as kind of "nothing up my sleeves" random number generator

zeroflow··on Ask HN: Why are credit card chip readers so slow?
They got slower.

Some years ago they punched in all items by number and were even faster.

The downside was that for the first months of your employment you were at home learning all codes.

zeroflow··on How the ARM ecosystem is addressing two key areas of automotive, IVI and ADAS
Also from what I've seen, the typical peripherals around a automotive uC differ greatly from a ARM "entertainment" SoC and that's whats the bigger difference. e.g. Infineon TC29xx http://www.infineon.com/export/sites/default/media/products/... vs Snapdragon 820 http://files.linuxgizmos.com/einfochips_eragon820_com_block.... Block Diagrams

In both of those chips the CPUs themselfes are the smallest part but the on chip peripherals differ greatly by usecase. The automotive has a great plethora of different busses and i/o (digital, analog, complex PWM, CAN, LIN, FlexRay) while the typical ARM core has less but higher bandwith IOs.

The other big step is backwards compatibility. Going to a completely different architecture is a bigger step than going from one iteration to the next one.

So probably even the "new" designs for 2020 may use the successor of the current generation of uC or SoC chips.

zeroflow··on An account of a serious medical emergency on a transoceanic flight
From my EMT course: The lawyer going after you would have to prove without doubt that the patient would clearly have survived if you didn't remove the bullet. In case of getting shot in the head, it's not very plausible that the patient would have survived anyways.

From a actual lawsuit: Someone without the proper training started an IV which later caused sepsis and death. Since the patient was admitted to an hospital it was not clear if an improply placed IV caused the death or an improper care in the hospital.

zeroflow··on Automakers Say You Don’t Really Own Your Car
Thats not true for all Motronic ECUs. The OEM has to decide which kind of tuning protection they want to have activated.

Some OEMs opt for the low settings where tuning gets detected and logged while still allowing you to run new or modified code while others only allow the flashing of signed code.

Also, as far as i know from motronic mods, they mostly only change calibration data and not the code itself, but i may be wrong.

zeroflow··on Replaced occurrences of master/slave terminology with leader/follower
It also wouldnt be a good fit.

- Master / Slave systems are typically locked in. One slave if a database system can only be a copy of one master and cant just switch freely between masters.

- Leader / Follower is coupled to loosely in my opinion. When i hear leader / follower i'm more thinking of a system where the followers follow the state of the leader (e.g. if the database goes down, the web frontend is shutting down / displaying an static error / ...)

[sarcasm] - Parent/child could be offensive to people who cannot have kids or whose kids have died! Have you thought about THEIR feelings aswell? [/sarcasm]

zeroflow··on Replaced occurrences of master/slave terminology with leader/follower
Reminds me of poe's law... http://en.wikipedia.org/wiki/Poe's_law It could be a parody or not, but until the writer states so, you cant be sure.

From my point of view, its a pretty bad idea. Master / Slave is used in nearly every system ranging from basic integrated circuits using a bus (SPI, I2C, ...) up to multi cluster database systems. It has a clearly defined function and and everyone in tech knows what it means. It doesnt matter if youre from USA, England, Germany oder Iran. A master/slave system has a clearly defined behavior.

Trying to bring feelings into the clean technical world it one of the most stupid things i can think of. In this case, it only affects the documentation of a project, but in other cases, trying to be politically correct has destroyed lifes of people. http://www.wired.com/2013/03/richards-affair-and-misogyny-in...
