Mistaken my identity on Twitter and the resulting harassment outside Twitter

To those who actually want to follow @coder.sara on Instagram and/ior Twitter. I am not he/she, Twitter seems to misinterpret @coder.sara as @coder . So for the clarification: I have nothing to do with this crytocurrency scammer and nothing to do with crytocurrency in general as I myself am very critical of these. Twitter should fix the handle-parsing, so it doesn't interfere with points/dots (@coder.sara <=> @coder ). 

As a result, among others, a female person from Italy (according to her Twitter profile) contacted me by email, where she found the email maybe by reverse searching my Twitter handle. She seem to have lost money at a crypto scam. At least she is now insulting and threatening me (though I'm the wrong person and not the scammer), even still after I tried to enlighten her about the identity confusion due to Twitter's incompetence. But no chance, she apparently wants to report me at the police now. For my part, my own report has already been filed. 

I had really tried to clarify her friendly, but … (read more)

The problems with the Intel Iris Xe (i)GPU archiecture in connection with USB-C and Thunderbolt docking stations.

I bought a new notebook (a gaming Asus TUF Dash F15 notebook, which I want to use as a workstation notebook), which also has an Intel Iris Xe iGPU (alongside an NVIDIA Geforce RTX3070). And that has exactly the same problems as my Samsung Galaxy Book Pro (also with Iris Xe iGPU) with USB-C and Thunderbolt docks with external monitors, with random dropouts and display timing mismatch problem. So there seems to be a general problem with the new Intel Iris Xe GPU architecture regarding the DisplayPort protocol over USB-C and Thunderbolt. Because I have six different USB-C and Thunderbolt docks, and with all of them the problems occur with these two different notebooks, each with an Intel Iris Xe (i)GPU. And of course, I've also tested through different cables and as well as different monitors, with absolutely no improvement. 

My new Samsung Galaxy Book Pro 13

I now have a Samsung Galaxy Book Pro 13 which weights only 868 grams. Unfortunately it‘s only the variant with the i5 and soldered 8GB RAM, because the variant with the i7 and 16GB RAM is no longer available and even nowhere in stock in the German DACH area. But I have already planned a BGA soldering upgrade to 16GB or even 32GB RAM by an expert in the field, where I am currently looking for someone who can do this for me. That means desoldering the old LPDDR4X RAM chips and soldering the new LPDDR4X RAM chips. Unfortunately BGA soldering is only possible with a professional infrared soldering device and the required skills to handle the soldering on the small scale of the chips. 

At the very least, the Samsung Galaxy Book with the i5-1135G7 beats my Thinkpad T480 with the i5 8250u and 32GB of RAM hands down in plain CPU performance, for the simple reason that the Samsung notebook simply throttles less often, if at all, whereas the Thinkpad T480 throttles frequently, if not almost always, and that's … (read more)
