Data center heat, with a little external help, warms homes of nearby residents. Nothing unusual or interesting.

Saved you a click.


Keep your ebook readers dumb and use them offline. Load them up with books and read them.


With plasma.

Saved you a click. The article is still good, though.


Looks like they need to learn a thing or two about integration tests, redundancy, and fail-overs.

A software update didn’t take it down. Negligence did. You should wonder why it doesn’t work before you ship to production.


A fuse is just an electronic component. It can be used for circuit protection, but it doesn’t have to be. For example, a transistor doesn’t have to be an amplifier, a resistor doesn’t have to be for dimming bulbs, etc.


“fuse” implies that the CPU will stop working

It’s just an electronic component, like resistors and transistors. Samsung has something similar in their phones called Knox.


I own the LCD deck and goofed off with the OLED deck. The screen is perfect, just like I imagined. But the thing that caught me off guard was how much lighter it feels. They say it’s 30% or something lighter, but because of the way that you typically hold it, it feels half the weight. The joysticks also have a deep recess on the inside, which makes your thumbs slip a lot less.

Overall, I would say that if you currently have a Deck and play it every day, if you can sell your old one for a reasonable price, the cost is probably worth it. If you’re a casual gamer and you only play every so often, the upgrades on the new Deck are great to have but probably not worth the cost. As a new purchase, OLED without question.




Whatever happens on my browser is client side, which is hardware and software I own. I can make what I own do what I want. It’s a right.

It’s like Google saying that I can’t skim a magazine in my home, and that I must read the ads. Google can do what they want server-side, and I’ll do what I want client-side.



Oh no! Now that shitty government websites with 12-character passwords don’t work, Firefox is dead!!

Get real. Too many of their websites only supported IE when it was around.


X is a confusing name, and news articles want to write clear content. That is all.


Personally, I’m okay with a small set of folks being rich as long as they pay taxes. I’m this case, a hell of a lot of taxes. You know, the taxes they should be paying, not what they manage to get away with now.

Let the legal system enforce that they give back to society in a meaningful way. Close the stupid loopholes. I want to see a meaningful improvement in society from their contributions. Everyone else is worse off unless they contribute.


It’s more or less a consumer version of their RA2 system, which is its own protocol. The gateway interacts with the whole system using commands issued over telnet though, so you actually have a command line for operating and configuring it. It integrates with a bunch of closed systems, and it integrates right into Home Assistant with a first-party HA integration.

It’s not like you can inspect the source code for their firmware push up pull requests on GitHub, so I’m this aspect, yes, it is proprietary. However, with tools like Home Assistant, which is something you probably should be using, this becomes much less of a concern, in my opinion. It’s robust, high-quality, and is commonplace, so you can get bits and pieces at Home Depot.

If you’re interested in something that will work with mesh networks and you aren’t interested in running software like Home Assistant, you should look for Z-Wave or Zigbee hardware. Read reviews though; I’ve had a lot of mixed experiences with hardware, even from “trusted” vendors.


I honestly think that he doesn’t have to face consequences like normal people because he has enough money to make problems go away. He can be an awful person in interviews, and mean his words too, then even bankrupt his company, and you know what? He will continue being excessively rich.

His money could be used to fix so many issues en masse. It’s disgusting that he chooses not to do so every day.



Try a Lutron Caseta dimmer with a Pico remote. They work together as-is without a gateway, and the Gateway Pro will join it to something like Home Assistant in the future. Or you can simply use the Caseta app.






Who needs FREEDOM when you can have ADVERTIZING COMPANY

Lower latency can be a big help as it allows quicker access

How much latency? Consider the speed of electricity at a few centimeters.

there’s a reason CPUs have caches on the die

The static RAM on the die is a different type of memory that’s appropriate for the CPU to use. It’s not that short conductor lengths magically make it faster.


Ah it’s cool, you can just open the little door in the back and upgrade the RAM anytime you want.

Right??


Putting RAM physically closer to the CPU does allow you to utilize the RAM better. It’s physics.

If the RAM was 3x closer, would it somehow be faster? I’m looking for metrics. With the same stick of any given DDR5, how much performance loss is there on a few example motherboards of your choice?

My point, again, is that yes, on paper, shorter wires means less opportunity for inductance issues, noise, voltage drop, cross-talk, etc. But this is all on paper.

It’s not like every motherboard manufacturer doesn’t know what they’re doing and Apple’s brilliant engineers somehow got a higher clock speed than what the RAM is rated for because… shorter wires?

Case in point: DDR4 is meant to operate at a maximum clock speed per the specs of DDR4. However, on plenty of motherboards that are overclock-capable will support memory that is more than 3x the clock of what DDR4 should be capable of. How does this work with memory that is not soldered into the motherboard?

Additionally, without overclocking, the memory is designed to operate at a clock speed. Will shorter traces to the RAM magically increase the capable clock speed of the RAM? Are these the “physics” you’re referring to?


The longer the trace, the more chance there is for signal loss.

While this is true on paper, we don’t need to pretend that this is an unsolved problem in reality. It’s not like large-scale motherboard manufacturers simply refuse to put their RAM closer to the CPU, and it’s littered with data loss. Apple also didn’t do anything innovative by soldering the RAM onto their motherboards. This is simply bootlicking Apple for what’s actually planned obsolescence.



Behind Every Self-Made Millionaire is a Father with Money

Well that’s just not factually correct


RAM is RAM. If you’re able to manage it better, that’s nice, but programs will still use whatever RAM they were designed to use. If you need to store 5 GiB of something in memory, what happens with the other 2.5 GiB, if they claim that it’s 2x as “efficient?”







It’s correct. The “1 billion” is a number written out. Think of it like $(1 billion). It can also be abbreviated to $1b.


Maybe I didn’t convey what I’m saying well. Facebook is attempting to take a name because they have money. Laws don’t really apply to them, they seem to think, and it’s because of their bullying and their money.


Heya! I thought I'd mention that I've been doing a bunch of development on the optical Timex Datalink watches! I have been carefully sniffing data from the original Timex software with a logic analyzer, and have fully reverse engineered every Datalink protocol, the serial Notebook Adapter, and even the CRT syncing graphics! This means that every Datalink device, including every Timex and Motorola watch, all PDAs, and the funny e-BRAIN talking toy is supported! For those that aren't familiar, the Timex Datalink is a watch that was introduced in 1994 that is essentially a small PDA on your wrist. The early models (supported by this software) have an optical sensor on the top of the face that receives data via visible light. ![](https://lemmy.world/pictrs/image/a44ab666-b473-429c-a122-ebe41d5dc767.png) The original data transfer method involves [drawing patterns of lines on a CRT monitor](https://www.youtube.com/watch?v=p3Pzxmq-JLM) for the watch to receive with the optical sensor. CRTs use electron beams that draw scan lines one-by-one from top to bottom, then it returns to the top and repeats for the next frame. This means that the electron guns turn on when its drawing a white line, and and turn off when its drawing the black background. This produces flashing light as the graphics are drawn, which is ultimately received by the optical sensor and decoded by the Timex Datalink device. ![](https://lemmy.world/pictrs/image/d6dbcb51-6c08-4c0d-954a-7c6da3eddd1f.png) For laptop users, Timex also offered the Datalink Notebook Adapter. Instead of using a CRT monitor, the Notebook Adapter simply flashed a single LED light. This adapter is fully supported by the Timex Datalink software, and sends the same data as a CRT. ![](https://lemmy.world/pictrs/image/b13cc9d1-890e-40fe-86d5-2d803f3ad3f9.png) However, Notebook Adapters are rare and expensive now, so I reverse-engineered one! Here's my timex_datalink_client Ruby library communicating with my DIY Datalink Notebook Adapter to emit data to a Timex Datalink watch! ![](https://lemmy.world/pictrs/image/15408128-09d1-4615-829b-d812d2a61af3.png) And if you want to try the reverse-engineered CRT graphics, I got you covered! I reverse-engineered that, too! ![](https://lemmy.world/pictrs/image/97488413-0b79-4467-982e-df7c66f5b81d.png) As a fun tidbit, these watches are flight certified by NASA and is one of four watches qualified by NASA for space travel! Here's a shot of James H. Newman wearing a Datalink watch on the Space Shuttle for STS-88! ![](https://lemmy.world/pictrs/image/5a55ed87-a974-4e5b-86b6-f77aafa4a1eb.png) Here is my Ruby library with all options for all watches reverse-engineered into a tidy model-based syntax! - https://github.com/synthead/timex_datalink_client Here is a Notebook Adapter emulator that is fully compatible with all Timex software on old and new machines, and also works with my library too! - https://github.com/synthead/timex-datalink-arduino And if you have an anchor that happens to contain an electron beam and wanna try it, here's my library for drawing graphics to a CRT to transfer data! - https://github.com/synthead/timex_datalink_crt This has all been done over months of careful effort with lots of VMs, Pentium machines, Windows 98SE, logic analyzers, and solving data puzzles little by little. On July 4th, 2023, I'm proud to announce that I have reverse-engineered every Datalink device with 100% feature compatibility! This is definitely a passion project by all means, and I thought I'd pop in and share this passion with y'all! Enjoy!
