manicdee··on Really Prolific?
“Innocent” third parties who scored a great deal on discount “Prol1fic” chips on AliBaba?

Provenance is an important part of logistics which you lose as soon as you source parts from third party sites like Amazon, eBay, AliBaba and so forth.

manicdee··on Really Prolific?
Your definition of sabotage is quite broad and creative. There is no damage to the hardware. The driver is simply not operating with hardware that Prolific didn’t get paid to support.
manicdee··on Really Prolific?
It is beneficial for their chips: the driver will work exactly as advertised and tested. The drivers do not break clones on purpose, the drivers simply don’t enable clones to work.

Write your own driver if you want to use the clones. It is not Prolific’s job to support hardware they didn’t design, build and test.

Even more importantly it is not Prolific’s job to support competitors who are not going to respect Prolific’s IP.

manicdee··on Really Prolific?
Yet if Prolific support the fakes, they end up wasting time and money trying to provide tech support to people experiencing issues with fakes, or having hostile customers trying to get refunds on fakes from Prolific.

The better option is to find ways to ensure you are buying legitimate items, such as avoiding Amazon, eBay, AliBaba, etc.

manicdee··on A city fights back against heavyweight cars
What encouraged sprawl was R-1 zoning where it’s illegal to build apartment blocks with cafes and grocers in them.
manicdee··on Researchers demo Bluetooth relay attack against Tesla
What lesson is there to learn?

Why do you single out Tesla?

The title is wrong, this is a generic attack against BLE.

manicdee··on Is It Safe to Ship Thousands of Electric Cars on Big Ships?
How many fires did it take to learn lessons about dispensing, storing and carrying petrol?

We’re quite happy with ships have huge reserves of flammable liquids (“fuel”) so why are batteries such a concern? Gas (methane, LPG, etc) doesn’t get this level of attention so why do batteries?

manicdee··on Netflix to Employees: If you don't like our content, you can quit
I don’t think it’s fair or reasonable to hire someone to help produce documentaries and then expect them to produce “ow my balls”.

I don’t think it’s fair or reasonable to hire someone to produce web sites in Flask/Vuex and then expect them to dedicate themselves to maintaining your PHP legacy systems.

manicdee··on Ask HN: Is it true that any community that grows big enough, gets ruined?
Dunbar’s number is basically the rule that when the population exceeds about 150 or so it rapidly fragments, based on observations of prehistoric villages.
manicdee··on Feeling uncomfortable when leaving phone at home shouldn't be normal
Someone expressed a problem they have which having a map helps them with, the reply was that people who need maps are lazy (despite the existence of maps suggesting that needing them is endemic to human existence).

Whose experience am I trivialising here?

I am not interested in participating in your purity politics.

manicdee··on Minnesota Wants to Ban Under-18s from User-Generated Content Services
Minors would end up seeing the same “sort by new” version of the site that everyone who sorts by new instead of hot/rising/popular/etc will see.
manicdee··on Minnesota Wants to Ban Under-18s from User-Generated Content Services
This won’t ban minors from the Internet, it will go a long way to helping avoid bad habits like catching up on social media turning into a three hour binge.
manicdee··on Minnesota Wants to Ban Under-18s from User-Generated Content Services
Yet here I am deliberately avoiding the features that Minnesota wants to ban. There is nothing hamfisted and misguided about this, the point is simply to ban the social media equivalent of casinos where the entire point of certain features is to stop you leaving by distracting you from the rest of your life.
manicdee··on Preview, the Mac app people forget about
The opposite of “sherlocking”
manicdee··on Preview, the Mac app people forget about
One feature I miss from Preview was being able to define bookmarks so I could make the TOC of a PDF clickable.

Still, being able to reorder pages, insert new ones or delete obsolete ones is pretty useful for scrapbooking an instruction manual for my whole kitchen so I can hand guests one document instead of a ZIP file with a dozen different docs in it.

manicdee··on Feeling uncomfortable when leaving phone at home shouldn't be normal
Just because you don’t have the problem doesn’t mean you should trivialise someone else’s experience. How rude.

Try listening more, and hold back from telling people how to solve problems they didn’t ask for help solving.

manicdee··on Ask HN: What's the most stable form of digital storage?
The best place to archive it is your current computer which you use every day, ideally with a VM of the machine that can run that code (maybe Open Virtualisation Format can keep it useable longer?). Then hope that when you want to use that program again in the future the VM will still boot on whatever host you have available.

Then come back to it at least once a year to run it again and make sure it still works.

At present we are lucky enough that Windows programs from 1990s still run under Windows 10 to some degree. Thank the folks at Microsoft for maintaining their operating system as a digital museum of archaic bug-compatible APIs.

Something to keep on the shelf would mean you ignore it for too long and it stops working.

Even something like a Python script may stop working due to changes in the language, and old versions of the interpreter no longer being maintained.

manicdee··on A YouTuber purposely crashed his plane in California, FAA says
The discovery channel didn’t try to pretend it was an engine fire. They set out to plan a plane crash with the full involvement of relevant authorities.

Idiot with dangerous machinery doing dangerous things and thinking they have it under control is the topic of discussion.
manicdee··on Florida says it rejected math textbooks for referring to critical race theory
What would raise my eyebrows is not using real world examples to help children understand mathematics. There are very few people who can handle completely abstract mathematics at any age, and it has been necessary to use examples such as counting rocks or sticks to teach basic numeracy since language was invented.

This need to ground the instruction in practical examples applies especially to statistics in schools where the most relatable population for discussing populations is the human population.

The history of erasing inconvenient populations by various deliberate or accidental means such as focussing on outcomes rather than causes is something that absolutely does need to be taught as part of a statistics course. When studying the physical properties of gasses we don’t ignore the spurious peaks in excitation data, we look for explanations as to why those two peaks in the hydrogen excitation experiment occurred. Binning by wider excitation ranges would have helped erase those anomalies, but the scientists chose to ask the question rather than hide the uncomfortable facts (“eliminate the outliers”).

We necessarily should be asking political questions in statistics because most statistics are innately tied to human behaviour, not pure mathematics or science. Are there more people working in maths and physics or law enforcement and legislation?

The best way to educate future statisticians about invisible populations is to teach them about the mistakes of the past. These mistakes include for example focussing on which current populations commit the most violent domestic crimes per capita without thinking to ask why people commit crime, and then comparing per capita crime rates to the various causative factors of crime (which might be for example wealth, access to employment, police hours per capita).

Everything is politics, any time there are one or more people involved. There is no escaping this even in mathematics. To pretend otherwise is to reinforce the erasure of oppressed populations such as women and non-majority races/cultures (and note that using the word “cultures” instead of “races” doesn’t stop you being racist).

Essay topic for today: is there race or gender discrimination in physics and maths employment in the USA? Why are there so few women in STEM and where do populations start to become more distinct? Is the bimodal distribution of various characteristics by sex sufficient to explain the male dominance of mathematics and physics and the rapid decline of female populations from high school through to the end of a bachelors degree? Are there factors apart from IQ that can explain the lack of women in STEM?

manicdee··on Florida says it rejected math textbooks for referring to critical race theory
It’s odd that you don’t instantly recognise your objection as whitewashing.

Covering up problems by referring to state-level statistics instead of looking at demographics is racist propaganda. Race is indeed a political tool, as are efforts to ignore it.

manicdee··on Florida says it rejected math textbooks for referring to critical race theory
Lots of words there with no evidence.

The actual training teachers are receiving is that there are many ways to teach things like long division, and insisting on only using one method is not useful to students.

As an example, when teaching multiples of 9 you shouldn’t just use rote learning but point out the internal checksum of multiples of nine (add up all the digits to get a single digit and you get 9, for the simple tables the first digit will be 1 less than the number being multiplied, so 4 x 9 is 36, 3 + 6 is 9, 5 x 9 is forty-something so working backwards 9 - 4 is 5, so 4 x 9 is 45).

In addition there’s the “times ten minus one” method: 3 x 9 is the same as 3 x (10 - 1) so 30 - 3 is 27 (and add up the digits to make 9).

Teachers need to be allowed to use multiple methods of instruction, and restricting them to only exactly what is in the syllabus is racist because then the only people who get the quality instruction are the rich who can afford out of school tutelage, ie: predominantly white populations due to institutionalised racism in the USA keeping non-white populations poorer than their mostly white neighbours. Yes, there are white people living in poverty but when you compare white to non-white populations in the same region they are still better off.

The shorthand in the USA is that any policy which keeps poor people from success is racist because the rich/poor divide in the USA is predominantly along racial lines.

manicdee··on Taiwan should destroy TSMC if invaded, suggests US military paper
For the technology we’re talking about a couple of cans of black spray paint and five seconds of operation would be far more effective at destroying the evidence than demolishing the buildings or machines containing the technology.

Why the fascination with violent methods instead of effective methods?

manicdee··on Ask HN: Why do password managers have TOTP?
If the key logger is in a peripheral then the TOTP/password manager can still protect from replay attacks. If the key logger is on the computer then it has access to the password vault and the vault secret.
manicdee··on Academe is a hotbed of craven snitches
Surely the issue there is not Title IX but vexatious litigants?
manicdee··on USB-C hubs and my slow descent into madness (2021)
One piece of e waste I had was an entire MacBook Air which was bricked by a USB-C hub with power delivery which Dane highly recommended. Apple fixed that problem by updating their firmware. Apparently even Apple has trouble with USB-C.
manicdee··on GitHub Incident
It only takes one month long outage of an international undersea cable to negate all the benefit of SaaS when that SaaS is hosted in or heavily depends on other services hosted in the USA or Europe.

DNS goes down for a particular dot com? BGP hijinks? Backhoe through the major fibre serving your workplace?

All of these are going to happen and will lead to downtime out of your control or the control of the SaaS provider.

Thankfully git is designed to be decentralised and developers can continue to work even if they have to use paper books as reference material and not Stack Overflow.

manicdee··on Connecting a gaming PC to Apple Studio Display
Same reason Dell adds USB-C, DP, HDMI to their monitors: so you can use their product in preference to someone else’s.

Buy the Apple monitor, be impressed, buy the Studio to go with it.

manicdee··on BuzzFeed investors have pushed CEO Jonah Peretti to shut down entire newsroom
It’s much harder to go private than it is to go public. Blaming the CEO is a short sighted perspective.
manicdee··on BuzzFeed investors have pushed CEO Jonah Peretti to shut down entire newsroom
Investors are the ones making the decision for higher profits in the short term over long term viability of the company. It is absolutely in the investors, usually profit hungry corporate investors like superannuation or the local equivalent.

Foresight isn’t profitable. Sustainability isn’t profitable. They want next years bonus cheques not a healthy retirement fund.
