  • I don’t understand why Cloudflare gets bashed so much over this… EVERY CDN out there does exactly the same thing. It’s how CDN’s work. Whether it’s Akamai, AWS, Google Cloud CDN, Fastly, Microsoft Azure CDN, or some other provider, they all do the same thing. In order to operate properly they need access to unencrypted content so that they can determine how to cache it properly and serve it from those caches instead of always going back to your origin server.

    My employer uses both Akamai and AWS, and we’re well aware of this fact and what it means.




  • ‘21 Model Y long range. Overall it drives well, and the supercharger network is really nice. We took it on a trip up & down a good portion of the east coast last year and never had any issues charging it. We have a couple 30 lb dogs that love going for rides, so things like dog mode are really nice as well.

    Things I really do not like:

    • The reliance on cameras for all sorts of features like auto high beams and auto wipers on top of traffic aware cruise control (aka autopilot) (and full self driving, if you have it). I regularly have the wipers go off on clear, sunny days. The auto high beams are so unreliable I don’t use them, and that means no autopilot at night. I have no faith in even trying out FSD because of how glitchy everything else is.
    • The minimal use of physical controls. I have to take my eyes off the road just to switch wiper speed/mode.
    • Software updates have, more than once, changed my settings for things like autopilot without warning, and I’ve only discovered it when driving and turning autopilot on.
    • The maps have lots of routing issues. It shows roads in my neighborhood that don’t yet exist (new development under construction), regularly routes me wrong ways (there’s a left turn near my home that it thinks it can’t take so it tries to route me two sides if a triangle as a result), and on our road trip we found a stretch of highway that it thought it couldn’t drive on and kept trying to route us along side streets. And there’s no way I know to report these issues so they can be fixed. Apps like Waze make that trivial.

    Pretty much all of these are reasons why I refuse to even try FSD and discourage others from using it. About the only way I’ll give it another chance is if a truly independent third party tests it and says all these issues have been resolved.


  • I admit I own a Tesla. Given all the recent erratic behavior:

    • Not only will I not recommend Teslas to anybody who might ask about it, I will warn them to look at company & CEO behavior over the years, and actively discourage others from buying one.
    • When the time comes, I will not be replacing my current car with another Tesla. I will still likely go with an EV, but by then there should be significantly more good (better) options available.

    About the only way I’ll change either of these will be for Elon to step down and completely remove himself from any control over Tesla. But I don’t see that happening and I certainly won’t be holding my breath.












  • 10 years ago I worked at a university that had a couple people doing research on LHC data. I forget the specifics but there is a global tiered system for replication of data coming from the LHC so that researchers all around the world can access it.

    I probably don’t have it right, but as I recall, raw data is replicated from the LHC to two or three other locations (tier 1). The raw data contains a lot of uninteresting data (think a DVR/VCR recording a blank TV image) so those tier 1 locations analyze the data and removes all that unneeded data. This version of the data is then replicated to a dozen or so tier 2 locations. Lots of researchers have access to HPC clusters at those tier 2 locations in order to analyze that data. I believe tier 2 could even request chunks of data from tier 1 that wasn’t originally replicated in the event a researcher had a hunch there might actually be something interesting in the “blank” data that had originally been scrubbed.

    The university where I worked had its own HPC cluster that was considered tier 3. It could replicate chunks of data from tier 2 on demand in order to analyze it locally. The way it was mostly used was our researchers would use tier 2 to do some high level analysis, and when they found something interesting they would use the tier 3 cluster to do more detailed analysis. This way they could throw a significant amount of our universities HPC resources at targeted data rather than competing with hundreds of other researchers all trying to do the same thing on the tier 2 clusters.



  • The email protocol, SMTP, was originally not designed with encrypting content in mind. Encryption was added years later, but as an option that is negotiated between mail servers.

    While large email providers like Gmail, outlook, etc. likely all support encryption as best as they can, all it takes is one misconfigured server, etc. to cause emails to be sent in clear text at least part of the way from location to another.

    It’s largely for that reason why a lot of people & organizations don’t trust email to be secure unless you use mail clients that encrypt and decrypt mail at both ends. But that’s a PITA to set up properly and manage.

    If your email is sent entirely within an ecosystem like Gmail then it’s likely encrypted the entire time. But as soon as it passes outside of Gmail to another organization there’s no guarantee it’s still secure. These days it probably is, as virtually every reputable internet provider & company is going to take the issue seriously, but there’s still the history of SMTP not being encrypted that haunts those in the security fields.
