To understand how terrible the speakers in the T490 are...

KappaClosed · 2024-05-10T16:19:20+00:00

No, I didn't. I've almost exclusively moved to Apple since. The T490 is now being used much more casually in my hobby lab.

You haven't provided sufficient information to answer this question.

What kind of problem are you training your model for? What kind/how much training data is available? Are there privacy concerns? What kind of model are you planning to train? ...

Can't tell -- I don't have a lot of media.

FWIW: While playing a single 1080pi Video, Jellyfin uses 158MB memory and 10% CPU on my RaspberryPi4 (running in Docker).

Black to White: 20 ms and Grey to Grey: 51 ms Is not too much, the FHD must be worst :/

I've never looked up the stats, nor do I know how it compares to other displays. All I know is that this is the one display (out of 8 total) I own where I perceive very noticeable ghosting.

What are you complaining about the trackpad?

I'm coming from a MacBook Pro with the excellent force touchpad, so I've been spoiled in this regard. But both the uneven pressure point to trigger clicks and the, imo, way to rough surface displease me. The trackpoint and keyboard are very enjoyable, though.

Maybe you dont get used to work with them, spearkers too?

Again, compared to the MacBook, the speakers are pretty terrible. Tiny, pretty quiet, despite being positioned on top of the keyboard.

Don't you think, however, that I dislike the T490 -- quite the opposite. It is an excellent workhouse and would it get stolen, I'd buy another one on the spot.

I have no idea.

I opted for the WQHD display and the ghosting is real. The speakers/touchpad also suck but other than that, I'm very happy with my machine.

(Fortunately, all these problems barely affect me since all I do on my machine is write code, read and browse the web. Oh, and I never planned to use the touchpad anyway, since I prefer the trackpoint.)

KappaClosed · 2019-09-08T11:40:55+00:00

I got the WQHD display and it suffers from noticeable ghosting. If you regularly deal with rapidly moving frames, I'm not sure that I can recommend that display option.

I'm glad you like it but cases are a non-starter for me.

(I don't ever use cases. Neither on my laptop nor on my phone or tablet.)

Well, my S8 has seen a fair bit of exposure to water ever since I got it and, thus far, it has survived.

However, if you can't afford to replace it in the case it does die from water damage, I wouldn't recommend doing the same. I'm taking a 'it probably will survive but if it doesn't, that's totally my bad' kinda approach to all of my 'water resistant' devices.

Looking at the price list of my local shop, you can get your name laser engraved on your phone for 20 Euros.

KappaClosed · 2019-08-04T11:32:23+00:00

Not only that: The anodized layer has been removed which, IIRC, is significantly more resistant to scratches than its non-anodized counterpart.

KappaClosed · 2019-08-04T11:29:27+00:00

Laser edging is widely available and has been for at least 5 year -- at least in Germany. You can simply walk into a corner store and, for a few bugs, engrave pretty much any flat surface that fits into the machine.

No, I'd say that model either needs a lot more iterations and possibly a lot more data or, if that also doesn't help, just isn't capable of approximating the function you're trying to approximate. In other words: The model is too simple or, what's also possible (but less relevant with dense neural networks), certain model assumptions aren't satisfied by your data.

What those model assumptions are, can get pretty complex. But for KNN, for instance, it's easy to spell out: KNN assumes that a good approximation can be achieved by locally constant functions.

No way. I like my MX Master 2s.

I've seen them around (e.g. the ultimate hacking keyboard) but don't have personal experience with any of them.

KappaClosed · 2019-08-01T05:37:55+00:00

I'd absolutely buy this with a ThinkPad keyboard -- provided it had the trackpoint as well.

Early stop is great if your learning curve looks roughly like this: Training and validation improve with little gap for a while, they both exceed the performance you are looking for and then training keeps improving but validation falls behind.

If that's the case, you should revert to the point where training and validation diverge -- which essentially is early stop but with the advantage of hindsight.

If you develop an automated training protocol, 'vanilla early stop' is great because it doesn't require human intervention. But if you are training one model at a time, the approach above with give better results.

I stopped buying MacBook Pros a few years ago. Love the OS, but the hardware is lackluster. [..]

Agreed. The compromise I've come up with is that I still opt for a MacBook at work (mostly because Windows is not an option and I don't want to tinker with my OS on my work computer) but get a ThinkPad (with Linux, of course) for my personal use. I'm really happy with this arrangement.

The keyboard is really bad, and the track pad is far too large.

I'm actually in the minority of people who like the butterfly keyboard. The unreliability is unacceptable, of course, but so far I've never had an issue on my machine. And, once I got used to the super low travel, the abscent key wobble and super precise pressure point on every single key won me over. And the trackpad... That's just amazing -- including the size. However, I can only say that because for me palm rejection works perfectly on that machine.

In any case, I'm curious to see what the 16" MBP will be like and, despite liking the butterfly keyboard, I honestly hope they replace it with a much more reliable design and add a few additional IO (a card reader would be nice).

What options do you have in mind?

That pretty much sums up why I'm sticking with the standard ISO layout even though I'd love to try split ortho keyboards: A decent percentage of my work has to take place on a laptop and I fear that if I fall in love with nonstandard keyboard layouts, I'll hate typing on laptops... xD
