yes.There are very fast laptops, but there is a basic problem, they have too little space. And too little space means too little things that you can add, that you can update for little extra if better hardware becomes available, but most importantly it means more space.
And more space means more air.More air means more cooling. More cooling means more switching elements that can switch faster without the box dying from heat death.
safe.A friend has a laptop with which he loosely inserts my desktop. In the end, it’s about twice as fast. He paid 7000,- Euro for his box, which is more than me for all the computers I have owned since 1990 together.
My last update, with which I caught up at 2/3 of his speed, cost me 70 Euros.Since I could still sell the old CPU for 45, actually only 25 Euros.
There’s a rule of thumb: you get half the power for double the money on a laptop.Many laptops (not my friend’s) also have reduced performance, narrower bus systems on the motherboard. If you compare a “same” PC or laptop that are the same as the processors, you usually find (not always!) that they are still much slower.
Because certain high freqens on components are not possible precisely because of space constraints, for heat reasons or because of the inadequate shielding, i.e. for weight reasons.And if they are possible, then only with the next generation chip. They are then significantly more expensive.
And not properly warpable.And you’re set to a monitor. You look down at him instead of straight. You can’t take off the keyboard and use it ergonomically under the table top, don’t let me start from the ergonomics of laptop keyboards.
A lot of things are worse.And if you don’t really have to be mobile with your computer, then a laptop is not worth it.
I have one.That’s the kind of laptop that others would throw away. In fact, someone threw him away and I caught him. I didn’t pay a penny for it. Runs. Have a computer on the go and the battery is fine. But I work on my main computer.
And the functionality of the laptop, which I need, now my smartphone is done.Together with a Bluetooth keyboard with touchpad. Together with installed Termux (a free Linux console with package manager). The thing can do everything I need. And it puts my laptop in my pocket.
And it wasn’t even expensive.And if I really need power, then I go via SSH via the Fon to my computer and work there, remotely. So to speak, my own “cloud”. If that’s not enough, I turn on my sleeping dwarfs arranged around my princess, my CPU. With a “wake” from the wakeonlan package, a small cluster then drives up and provides enormous computing power in the short term. After that, I turn it off remotely, because I don’t want unnecessary electricity bills.
That’s how I solved it.And I’m more computing power than anyone I know. Except said friend. He still has professional access to a cloud in a data center and that exceeds the possibilities of an individual there.
But it’s even less transportable.Only: the transport problem has been completely solved by working remotely and via SSH.
I call my cloud my scrap cloud.That’s all hardware that gamers have thrown away. And when you unite them, with graphics cards and processors, you get to insane performance data. Performance data that goes far beyond anything you could buy as a single computer.
In general, I’m totally in favour of Windows.Windows forces people to throw their computers away far too early. I catch them, I Linux eat them; they will continue to run successfully and productively for ten years. The complexity of my network is enormous, which is not much behind what you get in data centers. Of course, the hardware is all scrap value in the professional field. clear. But don’t mean it’s useless. At least not for me. What I have here, I have calculated it for fun, would have been the fastest cluster computer in the world in 2005, if I count the whole graphics cards of course only.
But it’s harder to program than in a data center.The hardware is very inhomogeneous. Soon I will expand my cluster with scrap laptops. They are still running, but are no longer to be used as laptops with burnt-out video outputs and the like. It’s going to be fun. That’s another ten nodes, maybe if I can revive them all.
And since I’m playing around with old simulators out of interest, I might build a cluster of simulated VAXes or something.In general, it is now possible to simulate mainframes from that time on a laptop without any problems. On my Raspberry Pi runs very successfully a PDP-8 with everything on it. Play around with it and I think there are some important drivers missing from the virtual drives available by default today. I’m doing this anew and maybe there’s a market for the service to host old big computers? That has to be hundreds that I could host here, without any problems.
I have moved away from the subject.But that is relevant. These are things you can’t do with a laptop. You can’t open things up, get out what’s valuable, unite the best things and throw away the real junk. They are as they are and are only a part broken, they are almost gone.
And everything I do, you couldn’t do on Windows, not even think.The software used makes more than the hardware these days. How much computing power do you really need?
Why, as an expert, is the hardware that others throw away enough for me?I don’t need more performance than anyone else. That’s right. But I know how to pick up and use what’s there. And scrap PCs are much better to use than scrap laptops.
Once the graphics card is through with such a thing, it will be hard to put on a Linux.This must all work out immediately with SSH or you have to start again from the beginning. With a scrap PC, I click one at short notice and can put the thing on.
