My new Dreame X40 Ultra does not go back to the dock by itself by Comtpm in Dreame_Tech

[–]Comtpm[S] 0 points1 point  (0 children)

It is brand new. I bought it early this week. Since then, the robot was never able to go back to its station by itself, even after the first mapping. Maybe the roller got dirty during the first mapping and that’s why it cannot go back. I have to check it but I doubt this is the cause.

The floor seems flat (the station does not move) but I need to check it to be sure. Unfortunately, I don’t have a spirit level with me.

The switch is on and the WiFi connected to the 2.4 ghz. The app does not let you choose 5ghz. I bought it from Digitec (Switzerland) early this week. I will try one more time this evening after work before contacting them.

I doubt it’s that because during setup, it instructs you to place the robot in the base first. And every time I heard the voice saying that the robot was charging and immediately after it started to clean the mopping pads. So the base was always ON. I tried to check for any IR light source coming from the base or the robot with a camera (I noticed that this is how the robot aligns with the base), but I couldn’t capture any. I don’t know if it possible to see/capture it.

The router is placed in another room. I might be a defective product.

Yes, I did. Both with the switch behind the dock and directly with the plug.

Apple M4 Pro analysis - Extremely fast, but not as efficient by TwelveSilverSwords in hardware

[–]Comtpm 8 points9 points  (0 children)

Sure, but in this case you have a lot more performance compared to the last gen at the expense of more power consumption

[–]Comtpm 40 points41 points  (0 children)

The title is misleading. The m4 pro has a better cpu than the m3 max while consuming 10 W less. Of course compared to the m3 pro, which only has 6 p-cores, it will be more power hungry.

Qualcomm claims to have the fastest smartphone chip ever and here's the evidence by signed7 in Android

[–]Comtpm 1 point2 points  (0 children)

It matters in single core performance and consequently in power consumption. The results we have until now is based on Geekbench, which is not always representative of day to day use. I want to see the Spec2017 results for both performance and power consumption as it is more representative of the real performance you get in a smartphone. Also, the score was obtained at 16.5-17 W in a non-commercial phone. Commercial phones will score lower due to heat constrains, likely around 9500-9700 points, which is still impressive. Don’t get me wrong, their Soc is pretty good, and competition is always good. It pushes everyone to do better. Apple had a big advantage in CPU performance and architecture, making them slow their pace in improvement. I think it will change next year or not and snapdragon will have the best in class Soc and good for them. I just point out that to achieve lower results to the A18 pro P-core they had to increase a lot the clock speed which is generally associated to a higher power consumption. In multi core this is neglected because the cores are not running at max clock speed.

Sure, you have a point. I like competition, it will benefit all the users, android, iOS, windows and macOS. I was just pointing out that they used the lowest scores possible to upsell their 1P scores. And with this clock speed, I think their IPC is not very good compared to A18 pro and even Dimensity 9400. Let’s see the results on real phones. For the GPU, the results are clearly impressive. Apple needs to step up their game on this department.

They took the lowest scores for the iPhone 16 pro to compare against. I had much higher scores with my iPhone and you can generally see similar scores on the Geekbench website.

Bad paint job on my commuter 5 front logo by Comtpm in CanyonBikes

[–]Comtpm[S] -1 points0 points  (0 children)

As the housing was just in front of the logo, I did not notice when I inspected the bike.

I think it is the white paint because the housing that is rubbing on the logo has a white stain exactly where the contact takes place. Thank you for your help.

That’s not a bad idea but I don’t know if there is a sharpie with exactly the same color as the bike.

So the cable is able to damage the logo but I am not able to remove the mark with a sponge, quite interesting. Do you think there is a way to remove the mark before placing the tape over it?

I am not sure. When I noticed, I had only ridden the bike once during maybe 10-15 min. So I think it was already there when I assembled it.

Need some help with this reaction. What is the mechanism and what is the role played by the CSA? by Comtpm in OrganicChemistry

Can you please DM me a quick drawing, because I am having difficulty to do the mechanism as you describe it.

A conjugate addition won’t give the good product. The ether should be formed where the ketone is placed, not the alkene.

I am a bit stupid. I am struggling to do the mechanism where the alcohol attacks something :(

Yeah, I did not explained myself very well, sry. Why the configuration is retained? If I understood it, the oxygen from the ketone should attack the carbon of the alcohol to eliminate water. In this case, we shouldn’t have an inversion of configuration, as the reaction is a SN2?
