These were all across-the-line, 3-phase 600v starters so there was no option to slowly start things up. Soft-starters would have been ideal but they are 5x the cost.
None, they will just claim that opening the device voids the security features.
I get a disturbing amount of equipment that does not take into account the inrush current of starting many loads at the same time. While each individual device is protected by a breaker that can handle the inrush of it's load the main breaker for the equipment is not sized to handle every load starting at the same time. The fix is to include logic that starts things up one at a time but convincing engineers, project managers, and machine owners that they didn't think of everything is an uphill battle.
Ones and twos of MW are indeed tiny loads, there is a 1MW motor where I work that gets flicked on and off like a light switch, but hyperscale canters are in the >100MW range, that's >1% of even the largest generating stations in the USA.
And you're not aiming for some physical resonant frequency of the entire grid, just the controller on your local generator, getting it to ramp up and down chasing just behind your changing load.
I live in Ontario and in the past week the difference between our highest and lowest demand was ~4.5GW, but those changes take place over hours. If you can ramp up and down a 0.1GW load over minutes there is going to be a point where some control loop can't keep up. Generators have physical inertia but compute loads do not.
I agree that it's not trivial, not cheap, and not efficient but with the state of the world it would not be a surprise if some nation thought it would be useful to burn resources in order to disrupt an important event, maybe elections?
Cool, I thought grid stability attacks would rely on large numbers of IoT devices but it looks like computing infrastructure is the better target.
Whether it's by buying and using a trillion tokens strategically or by inserting synchronized malicious jobs it should be possible to find some resonant frequencies in the line frequency control system. By loading and unloading multi-megawatts of draw you could get the local supply throttling up and down enough desynchronize from the larger grid. If you could get real time measurements of the line frequency you could use that to tune your malicious load and do the whole 'pushing a kid at the peak of their swing' thing.
To mitigate you would have to put dummy loads or some kind of minute-scale power storage onsite or nearby to compute loads.
Marketing wank made to sell e-waste to middle management.
Oh no! Not the businesses! They are like poeple but better!
Activism is expensive, canadians are poor but also have a lot to lose. Are you going to give up your apartment, your car, your internet and cell service because you think the canadian government is slightly more evil than other govenments?
I have noticed that the list of potential leaders is made up of a disproportionate number of stupid, ignorante or corrupt people.
> professional iPad users
No such an animal. I have recently been issued an iPad for logging jobs and material use, it's terrible. Tablets are essentially little TVs made for consuming images and video with minimal user interaction, when you have to start typing up a dozen lengthy descriptions of jobs on a touch screen it gets frustrating in a hurry. Most of the contractors that come buy have been been given iPads as well and are equally impressed with the experience.
I've used 3 Apple products for more than chance interactions. A MacSE for 5 years in school, a 2015 Mac desktop for 6 months in a printshop, and an iPad for the past 2 years at work.
The SE and desktop felt like modern machines, clicks and key presses had predictable results, applications did what you told them too. On par with the Win95 and Win 7/8 I was used to at the time.
Jesus Christ, that iPad on the other hand, feels like janky Windows Vista tech rammed together by an intern. Weird UI artifacts, making the same gesture can have unpredictable results, the only function that everyone in the shop found without failure was 'undo' because it is triggered by violent shaking.
Even simple tasks like sharing a photo saved from a website is bizarrely broken. Depending on whether you saved it as a file or 'to your photos' dictates which applications can then open/share the image. And I know Android is full of it's own foibles but they took a few months to internalize. I'm going on 2 years of 'features' breaking workflow, and pixel perfect taps to activate input elements that are 5% of the screen width.

It's weird how lazy people are unwilling to take the advice:
> Stop using the lazy answer box, it will make you lazy.
Oh no, don't want to hurt the tech billionaires' feelings.
The majority of LLM use is to make slop or answer simple questions that could have been searched. The mythical AI-Chad Coders are so rare that catching them in the anti-slop dragnet will not meaningfully decrease the quality of a big project.
I flashed my 4XL today (from the no longer supported Graphene). It's nice to be able to keep a 7 year old device runnin, when most people bin theirs after 3-4 years.
I flashed my 10 with Graphene as soon as it was supported and RCS was a bit of a challange as well. Both because of the recipient's device/settings as well as my own privacy settings.
Google hosts a significant number of bots. About half of my fail2ban list is google cloud IPs.
You mean exactly like rich cunts today? You never hear a politician or a CEO say "boy am I glad all those interns do the bitch work so I can look good on TV".
> There seems to be a real reduction in property crime in some places with cameras. I don’t think it’s realistic to take these down everywhere.
And the guy at the Honda dealer says I should buy a CRV.
Steal, lie, cheat, do what you want as long as you do not take from other _people_. A government is not a person, a business is not a person, a museum is not a person. They should not have the power to deprive you from accessing any media which they "own" but did not create.
I hooked up my local LLM with zim-tools and a 120GB copy of Wikipedia. With some very strict instruction it's turned into a bar-trivia machine, it can answer factual questions faster than I can look them up and it's all offline.
The fun starts when you ask it more complicated questions like 'i have a device that communicates with microwaves and draws a maximum of 20mA at 12v, is it safe for use near humans?' It will look up microwave safety, ionizing and non-ionizing radiation, workplace exposure limits and eventually come up with 1/4W is already safe and the device likely is not a 100% efficient microwave transmitter.
wtf, I thought this was THE cheap way to 3D.
> Your replies here suggest a level of cynicism that is, well, … , it ain’t pretty. It seems you think “fuck the human cost as long as I’m making money”. I’d suggest changing your outlook on life if I didn’t feel like it wasn’t such a lost cause.
This is the default business mindset. Push every rule and regulation to the limit in the name of profit, if you can break a rule with minimal concequsnces then pay the fine and move on.
Stellantis has a recall out for >1M vehicles because they catch fire even when turned off. Unless that kind of fuckup is met with business threatening fines it will happen again.
It's only behind a paywall for US users, for making their country great again a second time.
You expect people to treat devices with respect and responsibility? The VAST majority of people use their phones to stream an infinite sequence of clickbait, ai slop, and conspiracies for 6 to 8 hours a day.
Blue collar maintenance worker here. I will have a yearly average income much higher than most of my peers because I'll likely die before I can retire and spend it ;)
> it lets people who are good at setting direction to leverage these tools to have the direction concretely followed by something, without having to create a group of collaborators
It lets the unskilled access the tools of the skilled without having had to learn all the pitfalls, traps, and safety concerns. With video editing there may not be much at stake but we've already seen how sloppy code ~= vulnerable code when the prompter does not know what they are doing. What's going to happen when project managers start vibegeneering cars and buildings.
The browsers on the computers at work show that it is very much still the driveby tool-bar install days.
Chromium forks are not the same as Chrome but it does help Alphabet keep a strangle hold on the render engine ecology. And eithr way, monocultures are bad, a surprise vulnerability could nuke 70% of users overnight, which could be partiularly bad with features like WebSerial and WebUSB.
It's like Reddit and Lemmy. The majority of users did not switch to Lemmy but the ones that did seem to engage more and share cooler stuff. They are there on purpose, not because it's the default platform.
