  1. Price query about Samsung mobile phones

    Will get a new smartphone next year, choosing between Google Pixel and Samsung. We've had a few Samsung, they are in general quite good and display quality is top notch.  
  2. The War in Ukraine

    Whatever is going to happen, it's going to happen fast, not in 6 months. On the ground, it seems likely that Russian defenses will collapse quickly. Nukes won't change it. Chemical and biological weapons might, and I'm surprised not many people are talking about it. Russian defenses are falling so fast, that even if US and allies cancel support to Ukraine to force it to the negotiation table, I think the equipment on the ground is probably enough for the final push. So that invalidates Putin's current plan: to get western public opinion for negotiation, from nuclear threat. So Putin might escalate slowly, by using chemical and biological weapons. Those would be effective in reducing Ukrainian advances, and at the same time test US and allies, while holding the nukes as a threat of further escalation. One problem is that Russian troops themselves might not be equipped against biological and chemical weapons, so using them close to their own troops might be a problem.

    @Janx Spirit, I'm unsure if the occupancing network works in scale good enough for parking sensors. One thing is a 30cm accuracy (estimated by many) when driving, another is a 30cm accuracy when parking. Of course this accuracy is probably much better at short distances, so it might work at all, let's see.

    I guess supply chain issues, but I would wait to see how well it performs. Radar was removed and the system actually improved, from my experience.

    Starlink. His tweet was wrong on so many different levels, but the worst is it sounds amateurish. He knows shit about it and tweets a naïve solution.
  6. The War in Ukraine

    Musk is either afraid of having a russian sniper on his back, or as usual he's tweeting from the toilet between joints with friends. Seriously, just focus on engineering!
  7. The War in Ukraine

    No, US threatens to cut weapons and forces ukraine to sit on negotiating table. That's Putin's plan. I don't think it will happen and I don't support it.
  8. The War in Ukraine

    There is a 20x200km land strip near Kupiansk, that is not part of the "annexed" zones. Unsure if Ukrainians focus there now, to avoiding giving the russians excuses for the next week, or if they just focus on grabbing more inward, and ignore the nuclear threat. I think they will ignore the threat and attack both, Russians don't need valid excuses to do stupid things.   One thing nobody is explaining is where should Ukraine focus next. The south area are in theory easier to defend after occupation, as they have no border with Russia. But they are probably heavily defended by the russians now, and perhaps the logistics value of the east is more important.   But one questions why they don't attack: - down to Mariupol and cut the annexed areas in half? - Kherson, which is within 20km? And it's the door to Crimea. - Donetsk city, which is within 10km, and is the center of this mess?   Perhaps they are just waiting for southern troops to come to help on east, and then attack an undefended south. One thing is sure: east is now easier to attack, because russians keep falling back and have no long term defense placements.
  9. The War in Ukraine

    It's surreal that half the Donetsk and Zaporizhzhia regions, supposedly now Russian, were never, ever under Russian control! On Friday, a russian journalist asked a Kremlin representative if the annexation was only for the occupied parts or the whole region. The representative had no answer! This is so fucking stupid in so many different ways!   Again, I think Putin's plan is to scare western public with nuclear (with or without actually launching them) and forcing US and Europe to force Ukraine to concede land. So whoever on the west or in this forum who thinks we should negotiate, please don't make Putin's day.
  10. The War in Ukraine

    Conflicting news about Lyman. Ukraine clearly entering the city limits, but there are still troops inside. Seems many Russians left, but many were also caught or killed in the process. The Russian media is going nuts on this, saying either the Ukrainians are on drugs (they actually said "zombies"), or that reinforcements will come, or that Ukrainians are being killed by the thousands...    The minimum consensus information is that Lyman is hours away from falling, that many troops, especially the mercenaries, already fled (or tried to) and there are a few hundreds of regular troops, plus local militia, still making a final stand.   This is all happening while Ukraine army is already attacking further into occupied territory, so it seems we might see a large land grab in a few days, like we saw some weeks ago. Probably much less land area, but much more important settlements.   EDIT: Russia just recognized they lost Lyman. No news about troops who got stuck inside the city, but this might imply mass surrender or they managed to evacuate most during the night.

    I watched the whole thing in detail, here are my takes: - as an engineer, I would like to see as much as possible, but as an investor, I think Tesla should keep the robot project hidden, it's a weapon from far left against Tesla, and clearly an early prototype which media will make fun of. - the most impressive thing about the robot is they are thinking from the start in cost and energy consumption. This is not going to be a fancy prototype to show to investors, like Boston Dynamics. This thing is going to be mass produced! - the battery, power electronics, sensors and computer are all mature and already in mass production, because they are the same used in every Tesla. This is huge. My estimation (based on known costs) is that those core parts cost less than $2500, so a $20.000 "price" is not completely unrealistic - The big problem with Boston Dynamics is their software. The mechanics are wonderful and clearly the largest jump in robotics ever. But the software is very basic, and that's why the company goes nowhere and keeps being sold around. Tesla on the other hand is using the same software as self driving. Expect fast progress - DOJO is not yet paying off, but in Q2-Q3 next year will accelerate self driving improvements by a large factor - self driving team seems to be on a path for incremental improvements with no ceiling so far, avoiding local maximums found in 2017-2020.   The general media won't take this well, but anyone with more technical background can see there is some serious engineering going on, and especially a serious business plan.
  12. The War in Ukraine

    Seems Lyman will be recovered tomorrow. A Russian convoy is trying to break through, no chance to hold it for a few days, as Putin expected. Funny thing is this morning he said the Russian flag would never leave Lyman   Ukrainians are being smart. Instead of frontal attacks on entrenched cities, they get all surrounding villages and try to encircle them, forcing russians to flee and saving big cities from war damage.
  13. The War in Ukraine

    Lyman, an important city held by the russians, is currently surrounded. Inside the city there are thousands of Russian troops, with a lot of equipment. The city could fall into Ukranian hands before the official annexation on Tuesday, and deal a huge blow to Russia's claims. It seems like Russian leadership told them to hold the city as long as possible, in normal circunstances they would have withdrawn some days ago. Either they surrender quickly or this will be a bloodbath, just so they hold until Tuesday.   Putin now talks of "Peace talks". Typical tactic to slow down ukraine and allow russians to regroup. He seems scared.
  14. I never understood wind turbine opposition from the argument of landscape. For me they look like the best integration between technology and natural landscape, from pure aesthetic perspective.
  15. The War in Ukraine

    Tactical nukes won't win him the war. Ukranian plains are no good for that. He will just piss off people and if we're lucky, lose china's support. For sure he would lose India's support, Modi already started distancing himself.
