> If they had just stuck with 12VDC and buildings had 12VDC wall sockets everywhere, everything would have been fantastic.

Huh? We used to have low-voltage AC and DC powered cameras in the world (and we still do, too).

Those are awful in implementation because buildings, whether or old or new, don't have 12VDC sockets everywhere -- or at all, really.

Nor should they have 12VDC sockets for cameras; they're unnecessary.

I've run my share of siamese coax for low-voltage-fed analog cameras, and also separate power for low-voltage Ethernet-connected cameras, and I'm completely over those concepts.

With proper-fucking IEEE POE, we have standards and it only takes one cable to make it work properly instead of more than one.

If a switch isn't up to the power demands of a particular camera, then: No big deal. I can upgrade or supplement that switch without rewiring even more of the building than was already necessary to get Ethernet going.

(Structured cabling for the win.

Passive POE: Not even once.)

Yeah. When I was a high school student, we set up the new school network (end of the 90s). We used Windows NT on all the desktops and the domain/file server and SuSE Linux as a firewall/router. The whole setup was super stable and NT ran well, even on the modest desktop hardware.

When we graduated, maintenance was taken over by a local consumer PC builder and had no clue experience maintaining corporate/organization networks. They replaced all desktops and servers by Windows 9x (probably 98), as it was all they knew and the network was constantly down, desktops broken/compromised, etc.

NT 4.0 was a really good OS in those days for servers/work desktops. It was less great for games (though IIRC there was DirectX at some point).

> There are multiple PoE standards.

No, there aren't, not in the way you imply. There is the IEEE 802 PoE standards, which are all compatible (save for not enough power), and designed to carefully negotiate and especially never break non-PoE devices. And there is bullshit (sorry) like "Passive PoE" that is ironically an active violation of the IEEE specs, can break pretty much anything, and you shouldn't buy so the likes of Ubiquiti and Mikrotik finally get the wallet vote and stop f*cking doing. Unfortunately, the proper PoE PD logic is a few dollars of extra expense.

Yes, there is a slightly higher risk of killing devices due to faults in the PoE supply logic. I have the official PoE HAT for a RPi 4. I have to say it is somewhat poorly designed due to space constraints; the isolation between 48V and 3.3V should be better. I'm not even sure the RPi PoE HAT is spec compliant.

But I don't think you can/should blame this on PoE.

It's trendy on the left, including among leaders, to resign, to talk about being powerlessness and afraid, etc. Today's NY Times had an article interviewing pro-Palestinian protestors mostly saying it.

What a bunch of losers. And who would support them? Who is going to advocate for people who won't advocate for themselves?

Have you ever heard a leader talk like that? Is that what they remember Churchill saying, standing alone against the Germans? MLK facing the overwhelming racist power structure, law enforcement, etc.? Washington at Valley Forge - 'to my soldiers, I feel really hopeless. The Brits are the most powerful military in the world and we're just a ragtag, irregular local force. There's nothing we can do. I'm going to resign, cross the Delaware, and return to my farm to wait out the war with my family.'

Maybe Musk shouldn't have tweeted (then deleted) the obvious fact that Trump is on the Epstein list.

Makes you wonder, since Musk knew Trump is a pedo all along (and he loves calling people out as "pedo guy"), why did he invest so much money, time, reputation, ketamine, and Nazi salutes into getting Trump elected, then cowardly retract one of the only true things he ever tweeted, just to support the coverup instead of the truth?

The rule of law, democracy, freedom, justice - these things don't matter? They not only matter, they are the foundations of the U.S. and have inspired people for centuries, all over the world. Only the Democratic Party could fail to sell them to the public - they couldn't give candy to a baby.

It's bizarre to me how many professionals turn into raving idiots working for the Trump movement. Look at Gulianni, and many more who have filed error-riddled court cases and made absurd arguments.

There is something politically tactical about making extreme claims - it shifts norms, signals extremism to followers, etc. - but why shoot yourself in the foot like Halligan and many others?

How many people are needed to maintain instagram, facebook, etc? Wikipedia isn't just a collection of static content. The page contents include static and dynamic content (via a lua scriptable set of templates), semantic data (wikidata), multimedia management (wikimedia commons), editing tools (WYSIWYG editing, with full support of the wiki markup and templating), global caching infrastructure, multiple datacenters for HA/DR, etc.

There's also the need to support the staff and volunteer developers, which includes wikimedia cloud services, git hosting, config management and orchestration, CI, community hosted tool/bot services, etc.

WMF has ~600 employees, and that's quite lean, for a service of their complexity.

Yeah, and who's going to force the issue? The minute someone kicks over a trashcan it'll be declared as the latest national emergency and the loyal forces of law and order will be told to terminate whiny radicals in sight.

>after so many decades of squandering everything and letting itself both be bled dry and run off a cliff by a subversive element within

After everything is all said and done, I wonder if it would be possible to build out a data project tracking the people and the decisions that led to the outcome and also where all the wealth went. I guess this is impossible because too many people are unnamed figures just doing their part succumbing to inertia.

In that case, you don't want cloud; you want an MSP, whose core competence is running those IT services. They, in turn, have the skills to colo a rack at a DC or to manage rented servers, amortized across a number of clients.

In practice, there are two situations where cloud makes sense:

1. You infrequently need to handle traffic that unpredictably bursts to a large multiple of your baseline. (Consider: you can over provision your baseline infrastructure by an order of magnitude before you reach cloud costs) 2. Your organization is dysfunctional in a way that makes provisioning resources extremely difficult but cloud can provide an end run around that dysfunction.

Note that both situations are quite rare. most industries that handle that sort of large burst are very predictable: event management know when a client will be large and provision ticket sales infra accordingly, e-commerce knows when the big sale days will be, and so on. In the second case, whatever organizational dysfunction caused the cloud to be appealing will likely wrap itself around the cloud initiative as well.

It doesn't matter if they kiss to talk or pass on their memories as DNA or they exist in a permanent stat of ego death.

I like that this post and the migration focus solely on staging. Far too often, people report how much money they saved by migrating from Heroku/Render/Fly to a VPS with Coolify/Dokploy/Kamal. What these calculations usually fail to take into account is the additional management and maintenance effort required. While this is fine for side projects and non-critical parts (such as staging/preview environments), it represents a significant burden for productive environments with business-critical services. In this case, a correct and understandable decision was made. Thanks for sharing!

Exactly why I referred to drawing glyphs instead of characters :)

There's even more depth one can go into here: subpixel positioning. To correctly draw glyphs that may be on subpixel positions, you need to rasterize and cache glyphs separately for each subpixel position (with some limited amount of precision, to balance cache usefulness and accuracy).

However I have a feeling that describing an entire Unicode-aware text stack here may not be useful, especially if TFA seems to only care about simple-script monospace LTR.

> - Was having a conversation today about isolation and grounding for POE (product has a metal case). Do you have a reference? Or standard?

Huh. I'm not the GP poster but interesting question. AFAIK there is no proper ground reference on the LAN cable. I'm not sure I've ever seen a metal case… wait, I do, outdoor wifi APs have metal cases sometimes.

If you find out, report back ;D

> - Do you have a part recommendation or reference design for ideal diode POE?

I've done a PoE device (802.3at, 25W) and just went with TI's reference design; the higher power ones use ideal diodes, sometimes there's multiple circuit variants.

(It's not worth mucking with the PoE design for small-scale builds; the reference design might be a bit more expensive but you get that money back on way less trouble to deal with.)

I sometimes have to decide between running Claude Code headless with a prompt or let CC generate an application based on the prompt. (coining: Codification Threshold tradeoff)

The tradeoff is that the prompt is non-deterministic, but also more flexible. It can handle unknown situations. The generated code executes much faster and reliable for known situations.

If auto-learn would reduce the non-deterministic nature, i.e. chance of failing, that would speed up software development.

Well... not quite a rolling shutter.

It takes >900k pixels to shoot one frame of that (amazing) video, and requisitioning each of those pixels required physically moving a mirror along X and Y to align the single-pixel camera properly.

There isn't really a shutter at all, whether mechanical or electrical. And from my understanding, a "rolling shutter" usually refers to things like reading out a CCD array or similar, or maybe some mechanical aspect of a film camera.

But this isn't an array of anything. It's just a pixel, and some very clever work with motors, lenses, and mirrors.

(Up next: Someone will show up to tell me that an array of 1 item is still an array. yawn)

I mean.. Werner von Braun wasn't just "sort of a Nazi if you squint real hard", but an ACTUAL Nazi. At some point you need to focus on getting the job done, and not on purity tests and struggle sessions. THAT is why the US once got to the moon, while China starved 40 million of its own people, and the Soviet Union collapsed.

systemd-oomd, oomd, and earlyoom all do poll for when to actually take action on OOM conditions.

What I was trying to say is that the actual information on when there's memory pressure is more accurate for systemd-oomd / oomd because they use PSI, which the kernel itself is updating over time, and they just poll that, while earlyoom is also internally making its own estimates at a lower granularity than the kernel does.

For context, it's not even the first time he's condemned, but this time the crime was sever enough so he couldn't avoid prison.

He delayed the case enough (almost 13 years) so that he's now more than 70 though and I doubt he stays to long in prison because of his age.

But it's nice to see that he couldn't run away from justice forever and is finally in jail.

This is a solved problem, but for reasons I don't understand it has only been used in a few elections. Do this:

• Use paper ballots that are marked by the voter filling in ovals next to the name of the candidate or proposition they are voting for using a marker supplied by the election officials.

• These paper ballots can be hand counted or counted by simple optical scan machines that are already widely in use in many places.

• By using some clever chemistry in the ink when you print the ballots and in the marker used to mark it you can print a code in each of the ovals that is invisible until the oval is filled in using that special marker.

By using some clever cryptographic techniques to come up with those invisible codes you can make a system with the following properties.

1. After the election all of the cast ballots can be published, allowing anyone to do an independent recount.

2. Any individual voter after the election can, if they noted the code that was on their ballot for a particular candidate, verify that their particular ballot was included in the count and that their vote counted toward the correct candidate.

3. An individual cannot prove to a third party that they voted for a particular candidate.

Here is a paper on such a system: https://eprint.iacr.org/2010/502.pdf

Wikipedia article on it: https://en.wikipedia.org/wiki/Scantegrity

> The comment about Wikipedia supposedly putting companies out of business is so goofy I'm not even gonna comment on it.

I've learned that when people don't have any merits to argue, they turn to ridicule. Right back at you buddy.

> The difference is humans have a concept of truth, humans have intent. A person, taking an aggregation of their research, expertise, and experience to produce an article is (presumably) trying to produce something factual.

It's pretty naive to think that humans have intent and motivation for the truth, and no others. Just look around you in the world - most communication disregards the truth either carelessly or incidentally (because they are motivated to believe or claim something else) or intentionally (lots of that).

> LLMs have no concept of truth, they have no "intent".

My calculator app has no intent or concept of truth, but outputs truth pretty reliably.

I would not call validation of PCBs easy conceptually. We had to develop a lot of automation in validation to enable today production. Optical verification has been standard for many years, and X-ray is now getting commonplace also. Flying probes commonly used. Functional automated testing is standard for any non-hobby product. But you are right in that the automation overall was/is bottlenecks on the ability to do QA - which not only prevents defects from being sent out, but is also critical to systematic improvements in the production process (both tuning and new iteration). And I believe you are right to call out LLM based systems to be weak in this area, and it is a limiting factor. I believe that automated QA will be more and more critical to positive LLM impact.

Hi everyone, creator here. Thanks for checking out the project.

I started building this because I felt existing AI dev tools weren't truly "agentic." The real challenge was the self-correction loop—teaching the agent to read error messages and debug its own code. It's not perfect, but I'm proud of where it is today and think it's ready for the public to try.

The main reason for launching now is to get feedback and see how it holds up in the wild before I build more. The next major feature planned is a one-click Supabase or Shopify integration.

I'm here to answer any questions. Let me know what you think

I highly recommend visiting the niagara parks power station museum on the Canadian side - they have a very interesting exhibition of the old power plant. You can even go down to the old tunnel and walk through it to see how the water was diverted back into the river, fascinating stuff.

The Welland canal is also very interesting. There's something really cool about seeing a large ship moving _on_ a bridge while driving under that same bridge with a car. Also, the city of Welland has some nice bike trails iirc.

Seventh biggest economy with the 21st biggest population seems like an economy that punches above its weight. Plus a low GINI coefficient suggests there's less wealth divide than a lot of other places. Seems like they have a mature economy and don't need to grow forever like a tumor. Once you reach a certain point, optimizing for quality of life seems nice, and the French do seem to aim for that.

So my arista 710p-16p isn’t entries because it’s not 48 ports? Or my Nexus 9300 24p? I’ve got some old juniper 4300 32F ports handling 1g fibres (moderns arista switches aren’t great as the 25g SFPs won’t autoneg at 1g on fibre as they don’t support clause 37)

I thought it's interesting that GPT5's comments (on prompting it for feedback on the article) seem to overlap with some of the points you guys made:

My [GPT5's -poster's note] take / Reflections I find the article a useful provocation: it asks us to reflect on what we value in being programmers. It’s not anti-AI per se, but it is anti-losing-the-core craft. For someone in your position (in *redacted* / Europe) it raises questions about what kind of programming work you want: deep, challenging, craft-oriented, or more tool/AI mediated. It might also suggest you think about building skills that are robust to automation: e.g., architecture, critical thinking, complex problem solving, domain knowledge. The identity crisis is less about “will we have programmers” and more “what shapes will programming roles take”.

Don't buy Ubiquiti. Personally speaking, anyone doing passive PoE (even if only on other device series you're not looking at) is automatically on my shitlist.

I'm not surprised they can f* up a basic PoE injector. The reason for doing passive PoE is saving a few bucks, on the back of safety and compatibility. Of course they would try to pinch hard on the PoE injector too.

Oh and I'd say they (together with Mikrotik) are responsible for 90% of the bad rep PoE gets. The IEEE 802 stuff really just works. And I say that having been part of rolling out 15000 people conference deployments with several hundred wifi APs in the span of a few days. The only real problem is broken cables, but the Ethernet link commonly fails before PoE is impacted.

Hi everyone

We’re excited to share DreamOmni2, a new open multimodal image generation and editing model that supports both text and image instructions. It’s designed for creators, developers, and researchers who want more control, consistency, and creativity in AI-based visual generation.

What makes DreamOmni2 different

Most existing models (like SDXL or DALL·E) work only from text. DreamOmni2 goes further — it understands both language and visual cues. You can describe what you want and guide it with reference images. For example:

Replace an object or background while keeping the same lighting.

Transfer artistic style or material texture.

Adjust pose, hair, or expression based on a photo reference.

Blend multiple sources (up to four) to create new compositions.

Key Features

Multimodal Input: Combine text and up to 4 reference images for precise control.

Unified Generation & Editing: One model handles both creation and modification tasks.

Identity Consistency: Maintains subject appearance across edits and poses.

Abstract Concept Understanding: Works with concrete and abstract attributes (style, lighting, texture, mood).

Open & Extendable: Benchmarks, data pipelines, and model weights will be released.

Use Cases

Product image editing or visual prototyping

Concept art and style transfer

Fashion, portrait, and design exploration

In-context generation for creative studios

How to Use

Upload two images (the first one is your editable base).

Add your text instructions — for example: “Change background to sunset beach, keep lighting warm.”

Click Generate — DreamOmni2 processes both image and language cues to create the result.

Why we built this

Instruction-based editing has always been limited by language. DreamOmni2 solves that by introducing multimodal understanding, enabling AI to “see” what words can’t fully describe.

It’s all fine and dandy, but I wonder why so little discussion around this (mainly high-level comments “DBs are hard”?

> disco provides a "good enough" Postgres addon.

> This addon is a great way to quickly setup a database when Postgres is not mission critical to your system. If you need any non-basic features, like replication, automatic failover, monitoring, automatic backups and restore, etc. you should consider using a managed Postgres provider, such as Neon or Supabase.

How come automatic backups is considered an “advanced” feature?

Also I can’t think of a single application since 2012 that I have worked on that did not have a secondary/follower instance deployed. Also suggesting Neon and friends is fine, but I wonder what is your average latency, Hetzner does not have direct connection to the DCs these databases are hosted.
