If you don't need components on the bottom side, it saves money to not do so. That means the board doesn't need to go through another pass on the SMT machine.

Even if a board is double-sided, it is common to avoid putting major ICs on both sides, unless the space constraints are severe. Often, people will only put passive components on the bottom side.

The one I really don't get is that they funded Adam Neumann's new company after the collapse of WeWork. How stupid do you have to be to give that guy any more money?


You can insert arguments into an SQL statement with the (?1) style syntax. See the example here:

That is basically the idea behind https://lobste.rs/ . There's approximately zero spam or other bad behavior.

You can look at the full user tree (https://lobste.rs/users) and see if there's anyone you know who might be willing to invite you to join.


Very little spam, but also very little engagement. The same post on hn might have 100 comments and on lobsters it has four.


I think we need to stop using "engagement" as a measurement of anything related to quality and usefulness.


Quantity has a quality all of its own.


Sure. But the odds of finding an insightful comment on HN is much higher than finding one on lobsters, merely because there is more content.


As long as the growth rate is positive and it isn’t too expensive to host, a small stable growing site could be fine.


Hey!

I have been a good citizen of Hacker News for fourteen years now...

Anyone here would want to throw me an invite to lobste.rs?

:)


Haha that's my line! I would guess that those people who are already on the seafood website know other technical people in their day-to-day workspaces like silicon valley or Palo Alto or wherever, so it's easy for them to get a link. Meanwhile for those of us on the opposite side of the US or, barely in the Anglo-Sphere at all, we are on the outside looking in and are not likely to get a link just by being mostly lurkers and occasional contributors.

At least for me, I'm the only HN user I know except my dad who doesn't even post, he just got lurk links from his knee if the woods like hackaday.


I requested an invite from a guy I have only known via Reddit, we've never met IRL.


I can't actually remember who is the person who I requested the invite from, I think they were given out somewhat freely by some users.


You can look on your user page, or search for your username on the user tree page.


I did, but I can't say who that username is


Well, that would be an awkward DM to write. "Hello, you invited me to the website, but I don't actually know who you are."

Modern problems...


Why do you want to stick your opinion into something that you hadn't previously known about? What are you going to positively contribute to the discussion that will move things forward? How does that help?


Not OP, but stating that "ban for merely mentioning an un-person" is nuts looks like a positive contribution to me. Policies like this often stand because no one openly disagrees and no one openly disagrees because no one else does so you just assume everyone is OK with it. Until a child blurts out that the king is naked.

A prudent response, the revised ending of "The Emperor's New Clothes".


I want to shine more light on the nonsense.


The high-voltage side should be separated from the electronics, so it shouldn't be dangerous if you are observant.

It may be sufficient to just disconnect the antennas from the WiFi module, that will help prevent any network connections.


Disconnecting the antenna would still have leakage at close range. Grounding the antenna might be a better option. But in practice, the dangers highlighted by the article only surface when an attacker has control of many solar plants at scale.

Compromising an individual one by getting close-range physical access will be a local annoyance but wouldn't scale to a level where it can threaten the grid, so it limits the pool of potential attackers to local vandals (which can achieve their goals easier by just throwing rocks at your panels).


Without an antenna, even at close range, initial handshakes will fail or be unreliable.


Disclaimer, ymmw, if you have no clue about these systems (average people), you can still easily kill yourself in the process.


This is an interesting and fun project, I was glad to read about it.

It was a bit of a bold move to base this on a Model I. That system had an unreliable expansion interface, limited memory options, and emitted a lot of EM interference.


The museum has "Columbine III" (a slightly newer Super Constellation), which was also used by Eisenhower. It was delivered to them soon after it was retired in 1966.

https://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/Fact...

I saw this plane decades ago when it was in an auxiliary hanger, before being moved to its present location. It was in decent shape then (you were allowed to walk through it), and hasn't spent decades sitting outside.

Obviously, Columbine III is not in flyable condition, and will likely never fly again.


You can do this sort of thing easily with an old Chromebook as well. You can re-flash the BIOS from https://mrchromebox.tech, and then install a standard Linux distro on it. You can use an SD card or USB drive for additional storage.

Look around and see what you've got laying around!


As long as it's not an ARM Chromebook, yes. (I think due to ARM just being difficult to work with in general rather than malicious behavior from Google?)

Also note that you'll most likely have to open it up and unscrew the firmware protection screw. It's kind of annoying but it's not difficult and at least it's not iPhone-style "impossible".


Yes. The ARM Chromebooks suffer from long term support issues just like phones. Qualcomm and the other chip vendors will only support a given chip for a few years, and then that's it.

For x86-64, the peripherals are mostly standard, with the sometimes exception of suspend / resume support. So a regular Linux distro will often just work with little tweaking required.


There's a lot of quackery around these days, especially with regard to tech and finance.

There's quite of bit of quackery just with nutritional supplements, too. And people and companies try to bypass the FDA all the time with fake cures, the COVID-19 epidemic was just the latest version of that.

The FDA is over-zealous with their testing requirements. However, without them we will see an explosion of fake cures for everything. The legitimate pharma companies will lose money, or otherwise start cutting a lot of corners in the pursuit of profit.

We need something like the FDA to keep things in check.
