  • This is true, but…

    Moore’s Law can be thought of as an observation about the exponential growth of technology power per $ over time. So yeah, not Moore’s Law, but something like it that ordinary people can see evolving right in front of their eyes.

    So a $40 Raspberry Pi today runs benchmarks 4.76 times faster than a multimillion dollar Cray supercomputer from 1978. Is that Moore’s Law? No, but the bang/$ curve probably looks similar to it over those 30 years.

    You can see a similar curve when you look at data transmission speed and volume per $ over the same time span.

    And then for storage. Going from 5 1/4" floppy disks, or effing cassette drives, back on the earliest home computers. Or the round tapes we used to cart around when I started working in the 80’s which had a capacity of around 64KB. To micro SD cards with multi-terabyte capacity today.

    Same curve.

    Does anybody care whether the storage is a tape, or a platter, or 8 platters, or circuitry? Not for this purpose.

    The implication of, “That’s not Moore’s Law”, is that the observation isn’t valid. Which is BS. Everyone understands that that the true wonderment is how your Bang/$ goes up exponentially over time.

    Even if you’re technical you have to understand that this factor drives the applications.

    Why aren’t we all still walking around with Sony Walkmans? Because small, cheap hard drives enabled the iPod. Why aren’t we all still walking around with iPods? Because cheap data volume and speed enabled streaming services.

    While none of this involves counting transistors per inch on a chip, it’s actually more important/interesting than Moore’s Law. Because it speaks to how to the power of the technology available for everyday uses is exploding over time.



  • I would have a couple years ago. In a flash. We replaced our phones a while back specifically to have eSIMs. It truth, considering the cost of Canadian roaming plans the phones have already paid for themselves.

    Both of our old phones were single SIM, so using a local SIM would mean disconnecting our Canadian numbers which would put us out of touch with people back home. Which means that this card wouldn’t have work for us either.

    I was at the point of looking at buying a portable WiFi hot-spot, when I found out about eSIMs. So we went that route.


  • I have an Orange eSIM with a France number that I have kept alive by reactivating it at least once every 6 months. It’s good for all Europe, without roaming charges, so that’s easy to do. Having the same number all the time is convenient, but more importantly I have gone through the hassle of providing passport info to Orange, which is a government requirement if you want a number for more than a couple of weeks. I think that’s an EU thing.

    The local number is good for calling hotels and for making restaurant reservations. Just having that is a game changer.

    For my wife’s we don’t need a number, so I just use Nomad for her data only eSIM, and get a new one each time. The cost is about $12-15, and you get whatever carrier you get, but the service has been good so far no I keep using Nomad.

    We can text each other using WhatsApp, and you can even use WhatsApp for voice calls. The sound quality is acceptable.

    I think it’s a bit more than that. I think that the idea is that you simplify the problem so that the rubber duck could understand it. Or at least reformulate it in order to communicate it clearly.

    It’s the simplification, reformulation or reorganisation that helps to get the breakthrough.

    Just thinking out loud isn’t quite the same thing.




  • Yes, $15 CAD/day to “roam like home”. I have an Orange eSIM that I can keep alive if I use it at least once every 6 months - with a local french number that stays mine. It costs me about $40 CAD for a 30 day - 20GB top up. My wife uses Nomad for data only, we both don’t need local numbers, and it generally costs $12 CAD for 5 GB 2 week top-up.

    So I figure about $60-70 CAD for 3 weeks travel virtually anywhere in Europe. Calls and SMS included (for one) without long distance charges. Compared to $630 for “roam like home” for two people from a Canadian carrier - doesn’t matter which one as far as I can tell.

    We both recently got new phones to be able to use eSIMs.

    And the physical SIMs stay active. So my elderly parents can call my Canadian number if there’s an emergency and it will ring through.

    In fact, on our last trip to Rome, when we used a credit card at the hotel, it was refused and then seconds later I got a text from the bank asking for confirmation on my Canadian number. I had no choice but to text “Yes” back, and that single text activated roaming for the day and cost me $15.


  • Well, there are specific hardware configurations that are designed to be servers. They probably don’t have graphics cards but do have multiple CPUs, and are often configured to run many active processes at the same time.

    But for the most part, “server” is more related to the OS configuration. No GUI, strip out all the software you don’t need, like browsers, and leave just the software you need to do the job that the server is going to do.

    As to updates, this also becomes much simpler since you don’t have a lot of the crap that has vulnerabilities. I helped manage comuter department with about 30 servers, many of which were running Windows (gag!). One of the jobs was to go through the huge list of Microsoft patches every few months. The vast majority of which, “require a user to browse to a certain website” in order to activate. Since we simply didn’t have anyone using browsers on them, we could ignore those patches until we did a big “catch up” patch once a year or so.

    Our Unix servers, HP-UX or AIX, simply didn’t have the same kind of patches coming out. Some of them ran for years without a reboot.
