  • I would say that you make a decent argument that the ALU has the strongest claim to the “bitness” of a CPU. In that way, we are already beyond 64 bit.

    For me though, what really defines a CPU is the software that runs natively. The Zen4 runs software written for the AMD64 family of processors. That is, it runs 64 bit software. This software will not run on the “32 bit” x86 processors that came before it ( like the K5, K6, and original Athlon ). If AMD released the AMD128 instruction set, it would not run on the Zen4 even though it may technically be enough hardware to do so.

    The Motorola 68000 only had a 16 but ALU but was able to run the same 32 bit software that ran in later Motorola processors that were truly 32 bit. Software written for the 68000 was essentially still native on processors sold as late as 2014 ( 35 years after the 68000 was released ). This was not some kid of compatibility mode, these processors were still using the same 32 bit ISA.

    The Linux kernel that runs on the Zen4 will also run on 64 bit machines made 20 years ago as they also support the amd64 / x86-64 ISA.

    Where the article is correct is that there does not seem to be much push to move on from 64 bit software. The Zen4 supports instructions to perform higher-bit operations but they are optional. Most applications do not rely on them, including the operating system. For the most part, the Zen4 runs the same software as the Opteron ( released in 2003 ). The same pre-compiled Linux distro will run on both.

    Are you open to proposing your master plan?

    Ukraine has been invaded. Are you suggesting they do not fight back?

    NATO is not war. No NATO country has been attacked. Engaging against Russia directly would put NATO at war with a nuclear power. I cannot imagine that this is your plan.

    Not just “the West”, but everybody is on the sidelines as far as direct engagement goes. Most countries are assisting Ukraine where they can. Some to the tune of hundreds of billions of dollars. Most have imposed crippling sanctions. So. “sidelines” is a bit misleading from that perspective.

    Even Russia’s allies are “on the sidelines”. You certainly do not see much overt support from China. They have even maintained ( in fact stepped-up ) diplomatic relation with Ukraine.

    Or are you trying to imply that the underlying cause of everything here is something other than Russia’s continued invasion? Everybody could truly go back to the sidelines if Russia just left.

    The only other path is for Ukraine to win. Are you supporting that or not?



  • I have not read the article yet but the headline saying “equivalent to an 8% raise” does not just have to mean some kind of soft value. I have to drive 50 km each way to my office. I am much more likely to eat out while at work ( or to hit a drive-thru on the way home ). Given the price of gas where I live, going to the office probably costs me $50 a day more than staying home. That is $50 after tax so you can simplistically double that in terms of salary that it consumes. If I have two jobs to choose from, from a purely financial stand-point, my current job and a fully remote one that pays me $100 less per day are equivalent in terms of the value they bring to my family.

    Crap. I have been a “want to be in the office some of the time” guy but making me actually type this out has made me question that. I think I need to start shopping my CV.



  • The brand promise of Reddit was pretty simple—it was the “Front page of the Internet”.

    It did not get popular because of the sub-communities or that there was a sub for everything ( at least not at first ).

    Reddit became a thing because it was a single destination that aggregated and curated interesting content from the web that “interesting” people could comment on. If you were only going to make one stop on the Internet, it could be Reddit. Uses could share the main URL by word of mouth and new users would get the same experience. As content grew, Reddit became high ranking in search results.

    Lemmy does not really offer the Reddit experience to a new user. New users do not want an offer to find an instance or create one, they want to experience the content, get addicted, and come back.

    The closest Lemmy has right now to early Reddit is Lemmy World but how do new users know that? Actually, I guess old.lemmy.world is the closest. :)

    My wife drives a Tesla and I drive an ICE SUV. We both drive a lot including long commutes. We have kids and busy lives which means frequently tight schedules to get to drop people off before work or get somewhere to pick them up or something else up after. Once you pick people up, you often have to get them somewhere and, once you do, you may not be able to leave until the next tight turn-around.

    Having to stop for gas when I do not have time is a frequent problem for me. I greatly envy my wife who leaves every day with a full charge and who almost always manages to go everywhere she needs to go without running out. She “refuels” at home. I go further on a tank but I cannot refuel at home and so filling up is just another think that has to fit into the schedule.

    For most “long” trips, we take her car. Far cheaper and again usually easy to charge overnight. Travelling between cities, we often combine grabbing food or taking a break from driving with stopping a charger. It does take a bit more planning but we have a lot more control over our time in these situations. In practice, it does not feel like much of an imposition.

    I would take not having to worry about keeping the tank full day to day for a bit of extra planning on longer trips any day.

    That is the stress and coordination aspect. Absolute time spent, it is not even close. An EV commuter spends way, way less time “filling up”. On most days, it is literally just a few seconds when leaving or returning home.




  • The concept was known but far fewer people had been exposed to those ideas and thought in those terms. That you think it is so obvious or that math as complex as geometric compounding is so obvious to you would be the actual big reveal.

    On prices, the really interesting thing is not that prices are higher but that what things are expensive and what thing are cheap has radically changed. Basic food and clothing is dramatically more affordable. Anything involving human craftsmanship is much more expensive. What os available for sale would absolutely boggle the mind. Not only did a huge amount of it not exist in the past but, only a long could even contemplate buying most of what did exist—at any price. Food is a great example. Empires rose and fell pursuing or exploiting the riches of fruit and spices I can buy for the change in my pocket from any of a half dozen merchants within a couple miles of me competing for the privilege.

    The fact that I can buy anything not only by waiting a piece of plastic at time but also the magic brick in my pocket ( phone ) might intrigue them as well. Basically, not matter what wonder you go to show, the real magic might be something so basic to our everyday that you did not even consider that it was required for the thing you are trying to show.
