bArray··on CEOs to Keep Spending on AI, Despite Spotty Returns
> After a year in which trillions of dollars worth of AI investments buoyed global markets and the economy, 68% of CEOs plan to spend even more on AI in 2026

They are too far in to turn back. They got into AI via fear of missing out (FOMO) and now they are too heavily invested to write it off on their balance sheet. To revert now would cause nothing but trouble.

> Less than half of current AI projects had generated more in returns than they had cost, respondents said. They reported the most success using AI in marketing and customer service and challenges using it in higher-risk areas such as security, legal and human resources.

I.e., the best success has been in cutting jobs, not in aiding the productivity of individuals.

bArray··on Pro-democracy HK tycoon Jimmy Lai convicted in national security trial
I wasn't suggesting the time periods are the same. The point is that we were willing to defend Ukraine against Russia, when it's the EU's problem, and refused to defend Hong Kong against China when it's a problem of our making.

Nobody in their right mind is keen for a war. Nobody would fight in one unless they believed they really had no other choice. I don't blame the people who would runaway to relative safety if the option is available.

But. It's clearly a massive security issue.

> If you’re that keen, go join the reserves?

There is not currently a war, and if there was, there wouldn't be a choice but to join.

bArray··on Pro-democracy HK tycoon Jimmy Lai convicted in national security trial
Remember, Hong Kong was supposed to be in a 50 year transition period from 1997 where there were supposed to be one country, two systems [1]. The national security legislation is just one in a long line of failures [2]. If nothing else was learned, it was this: China, specifically the CCP, cannot be trusted.

It makes me sick that the UK sends billions to Ukraine to interfere in a war we have no fundamental right to involve ourselves in, meanwhile, Hong Kong was allowed to fall with only light media coverage. It is outrageous. The politicians that oversaw it should be ashamed.

Not to mention that Carrie Lam, former leader of Hong Kong, sold her people up the river by allowing the national security law in [3]. She was even hiding out in the UK with her husband from her own countrymen.

bArray··on Twelve Days of Shell
Great idea, but a few feedback points:

1. It's difficult to know that it is following from the previous problem, and then on some problems it changes the workspace.

2. It's not always easy to know what it wants.

3. The question about finding a line starting with "The" I successfully cheated:

     cat night-before-christmas.txt | grep "The "
4. Likewise the ending "!":

    cat night-before-christmas.txt | grep "!"
5. On the eighth day I get a "runner error" with the command:

     mv *lve* Workshop
I'm globbing for the filename match, I'm not sure if it's "elve" or "Elve" and then trying to move to the target directory.

Otherwise it's quite fun - the instant feedback is great.

bArray··on Why are 38 percent of Stanford students saying they're disabled?
In Universities in the UK, and likely elsewhere, you get extra time during an exam if you have a qualifying disability.

As said by Charlie Munger: "show me the incentive and I'll show you the outcome". In the UK, 23% (and climbing) working age adults are now registered as disabled [1]. For a qualifying disability you can claim personal independence payment (PIP) that gets you between £73.90-£110.40 for living plus £29.20-£77.05 for mobility, which is not means tested [2]. That's up to $249.98 USD a week untaxed on top of your regular income - you can imagine why people may be incentivised. Worse still, Citizens Advice which is 60% taxpayer funded [3], actively tell people how to fill out the forms to guarantee a positive outcome.

I have no idea why people would want to register as disabled though... /s

I get the feeling that MathML will win out, simply because Firefox supported from early on [1], there is first move advantage. I use an old JS library for backwards compatibility [2] that adds just enough support for any math I'm math'in [3]. I would still prefer SVG, but it ended up being a pain to implement reliably.

One thing I noticed about this site though is that it is laggy - and I have a pretty good system.

bArray··on Show HN: An LLM-Powered Tool to Catch PCB Schematic Mistakes
I've tried it with one of my quick circuits - it does work to some extent. It found a requirement for an IC that I missed in the datasheet. Querying it further did confuse it a bit, instead of talking about the IC it started referring to the MCU and it's limits whilst referring back to the original document.

The real question is whether this has enough value to justify the pricing model [1] - I think so for a company, but would be difficult to justify for a hobby. One thing that should be defined is what "usage limit" actually is.

bArray··on Bringing Sexy Back. Internet surveillance has killed eroticism
> [..] seem to have internalized the internet’s tendency to reach for the least charitable interpretation of every glancing thought and, as a result, to have pathologized what I would characterize as the normal, internal vagaries of desire.

I think the internet has some ownership of this, AI didn't help, and our transition from a high-trust society to low-trust society. It's more obvious if you switch the subject to any other - try telling a joke about racism in the wrong setting [1]. Private things should remain private, and consumed within a private context.

In the UK for example, a person can be found guilty under the Malicious Communications Act and/or Online Safety Act. If your badly received joke involves a protected characteristic, that's now and aggravating factor and you just committed a crime against a protected minority.

> I should state at this point that this is not an essay about “cancel culture going too far,” a topic which can now be historicized as little more than a rhetorical cudgel wielded successfully by the right to wrest cultural power back from an ascendant progressive liberalism.

The author was IRL cancelled by their friend: "In fact, it ended the friendship.". And the main complaint is that this has become part of the culture, specifically for sexuality. The author may not want to associate with the anti-movement for cancel culture, it is exactly what they are aligned with.

> #MeToo was smeared by liberals and conservatives alike (united, as they always are, in misogyny) as being inherently punitive in nature, meant to punish men who’d fallen into a rough patch of bad behavior, or who, perhaps, might not have done anything at all (the falsely accused or the misinterpreted man became the real victim, in this view).

You want the power without the responsibility of corruption. It's not like this stuff doesn't have real world consequences [2]. If, instead of adding names to a document, each of these women just stabbed to death the men they are accusing, let's say for really terrible accusations that we can agree that such a penalty should apply for. Sure, many people who are stabbed to death will have earned it, but we cannot be sure unless there is some right to address the accusation.

The point is that without the ability to represent your counter-argument, there can be no real claim of justice. What is claimed as "social justice" is just the vigilante mob doing whatever it likes without accountability, and a lack of accountability is exactly what they are angry about in the first place. Two wrongs do not make a right.

> But that link between sex and fear is operating in more “benign” or common modes of internet practice. There is an online culture that thinks nothing of submitting screenshots, notes, videos, and photos with calls for collective judgement.

Wait wait wait. Hold on a damn second. We just literally spoke about a series of women submitting online notes for collective judgement. Now it's wrong?

This reveals the fundamental problem, which is that the author is suppressed by the very behaviours that they have supported.

bArray··on ESP32
The ESP32-P4 [1] could be interesting for running native Linux [2], but as the article suggests it was supposed to be released in January 2023. We're now approaching January 2026 without a final design [3].

I believe there is a strong market out there for a low-level Linux capable controller with WiFi, Ethernet, USB host, etc, capabilities. The USB itself would be especially killer - imagine being able to just load the appropriate kernel driver for a USB device and being able to communicate with it directly.

The original author of YOLO and the Darknet framework [1] issued the code under pretty much every license you wish to use [2]. My preferred fork by AlexeyAB is under an equally permissive license [3].

Ultralytics then created their own model under the AGPL-3.0 license [4], which probably would never stand up in a court as they have the model from the likes of YOLOv3 in their source [5].

This entire article is flawed anyway, because they don't state which YOLOv11 model they are using or compare the accuracy. They appear to have just taken the pre-trained models and assumed it's apples-to-apples. They could have at least compared YOLO11n/s/m/l/x,

It would be more dangerous if we had less people who had not taken the UK driving test? Are you mad?
bArray··on Nearly all UK drivers say headlights are too bright
If only we knew!

The real reason we drive on the left is so that our driver's windows meet in the middle and we can use our right hand to do sword battles and jousting with oncoming vehicles.

bArray··on Nearly all UK drivers say headlights are too bright
In my personal experience, ageing drivers drive too slowly, but they are generally safe. They will often stop driving when they feel it is no longer safe, and almost all older drivers I know refuse to drive at night.

Whether it is ageing or non-native licenses, I think a case can be made for checking that people conform with local expectations for driving skill.

bArray··on Nearly all UK drivers say headlights are too bright
It's supposed to already be done at the MOT stations. They are supposed to check the level and adjust it to conform.
bArray··on Nearly all UK drivers say headlights are too bright
Exactly. The signs are different, the cultural norms are different, etc. It annoys me that people believe that all Europeans are somehow interchangeable and universal. It does take time to adapt properly.

I almost did the same in France many years ago taking a slip road onto the motorway, almost rolled the car.

bArray··on Nearly all UK drivers say headlights are too bright
The data is based on casualties, but I think there are some points masking the issue:

1. Traffic is slower due to the decreased speed of traffic because of increased number of vehicles, and they continue to improve their safety (i.e. with proximity sensors & cameras). It's likely we see a reduction in casualties and fatalities even if number of accidents in total increases. For example, the number of accidents on the M25 may go up, but whilst they have speed restrictions for large areas of 50mph and sometimes 40mph, casualties will be decreased.

2. Payouts for minor injuries such as whiplash were pretty much stopped by insurance providers. Historic figures are likely inflated and new figures are likely deflated due to claims not being accepted.

3. Due to the cost of living and insurance hikes, we likely see people try to avoid making a claim. If a claim is made, the insurance premiums for both parties is increased (no matter who is at fault), both parties can be without a payout for a long time, the vehicles may be categorised and lose their value. If both vehicles are still drivable and an agreement can be made, the entire incident can go without being recorded.

The problem with proving the above is the linked data you have is for casualties, and insurance claims data I believe will reflect similar issues. I'm not sure how you would encapsulate people who have an accident but refuse to make a claim. Perhaps motorcyclists and pedestrian casualties may offer a ground-truth, as either rarely have a collision involving a vehicle where there is a choice to not make a claim.

> The source of this claim, which you helpfully did not provide, is Rupert Lowe, a far-right UK politician and shite-merchant who is so toxic he got kicked out of Reform.

On another day you would claim that being a member of Reform is toxic, and that being kicked out is a sign of being normal. Being kicked out of Reform is clearly itself not a sign of being toxic.

Rupert Lowe is an elected MP that has published his own policy paper [1] that remains uncontested, with the only criticism I can find is based on who helped him write it [2] and not on the content. He is democratically elected and partakes in the open exchange of ideas, I think the toxicity lives in your head.

> He does not give any indication as to where his number came from.

He literally says that they are processed from the Department of Transport. I imagine he will publish some materials soon.

> This reciprocal scheme only applies to certain countries: the EU/EAA, Australia, New Zealand, Canada, Japan, Korea, Switzerland, etc.

New Zealand for example only allows UK full license holders to drive for 18 months [3], not indefinitely. New Zealand roads are wide and vast, and public transport is somewhat limited. But for EU/EEA license holders driving in the UK, they can drive for as long as it is valid or until they turn 70. Even if you are on a shorter list and have to exchange in 12 months, it's just a small fee - no test [4].

The point is that we have many, many people driving on the roads that have never done a UK driving test. And this doesn't even begin to extend to those who are disqualified or driving under the influence. As a driver, it is getting far worse out there.

> I think when you are blaming things like headlight brightness on those bloody foreigners, it's time to do some self-reflection.

The second paragraph started with: "The quality of driver is also decreasing.", because I was making a related but separate point. I'm clearly not blaming headlight glare on foreign drivers. Maybe it it you that should do some reflection.

I think most vehicles are operating with their headlamps adjusted too high. I think the majority are now completely out of spec [1]. My normal lights are very respectably adjusted and are the older dimmer type, but my full beams are blinding - I rarely ever use them. A few times a driver comes towards me with full beams on, I flash mine and light up the entire night.

The quality of driver is also decreasing. One of our MPs computed the data and discovered "Since 2016, 1,367,942 foreign drivers have been issued a driving licence without taking a UK test". There are apparently 42.1 mn licenses [2], so ~1/30 never took a UK test. It's getting dangerous out there.

bArray··on Linux on the Fujitsu Lifebook U729
Can back this. Many years ago I purchased a Dell Latitude from eBay. After messing around with a 3D printer, there was a short of mains voltage onto the USB line, frying the laptop and tripping the house electrics. I contacted Dell asking for a schematic of the PCBs thinking that I had blown some components, but they informed me that the laptop was still under warranty thanks to the original business purchaser (by just a few weeks).

They shipped a box and allowed me to swap out a hard drive for a spare (I had study data on there), I then used the box to ship the laptop to them. A few weeks later the laptop gets shipped back with a parts replacement list, which was essentially every single PCB in the laptop and I asked them to replace the keyboard too because one key was sticking. Brand new parts in a slightly cracked chassis.

If Dell still has customer service like that, it's double thumbs up from me.

I'm currently using a Lenovo laptop which has been solid so far. I do want my next laptop to be open to repairability (even if I have to create it myself).

bArray··on Laptops with Stickers
Worth noting is that there is a non-zero number of political stickers on these laptops, and they seem to all tend towards the far-Left. It could make one wonder about the general political leanings of hackers and open source contributors.

Why is it important? A lot of projects took a stance on Russia-Ukraine [1], GitHub blocked the entirety of Iran [2] and I don't doubt that codebases now take a stance on Gaza-Israel.

The top-middle says "NAZI HACKERS FUCK OFF" [3]. They likely mean a new definition of "Nazi", and that could include you. Why point out this sticker particularly? Because it is directly aggressive towards a hacker they perceive to hold that label, and that they have labelled that group with one of the worst possible labels. By doing so, they can justify pretty much any level of aggression through the use of dehumanisation (ironically, a method employed by the Nazis).

The Python Software Foundation refused $1.5mn in funding [5] because they could not agree to be non-political. They would not agree to act without favour. Maybe today this doesn't concern you, but look more closely at the stickers of the people that have infiltrated these institutions. Do you think that you will indefinitely remain on the "good side"?

The Linux Kernel's previous Code of Conflict [6] was quite a rational approach, it was a market place of ideas (contributions) where they did battle. There was no barrier to entry and everybody would be critiqued equally, in the single objective of creating the best possible kernel. Diff this with the current Code of Conduct [7] where there is a barrier to entry, and the focus is on the feelings of the people and not on the quality of the kernel.

We should keep politics out of code entirely, and the quality of the code should speak for itself.
