  • Postgres handles NoSQL better than many dedicated NoSQL database management systems. I kept telling another team to at least evaluate it for that purpose - but they knew better and now they are stuck with managing the MongoDB stack because they are the only ones that use it. Postgres is able to do everything they use out of the box. It just doesn’t sound as fancy and hip.




  • Extremely cheap per kilowatt? Every statistic out there that I’ve seen and that includes government funding, as well as construction and deconstruction costs, paints a different picture. Nuclear is only competitive with coal or the relatively underdeveloped solar thermal.

    In 2017 the US EIA published figures for the average levelized costs per unit of output (LCOE) for generating technologies to be brought online in 2022, as modelled for its Annual Energy Outlook. These show: advanced nuclear, 9.9 ¢/kWh; natural gas, 5.7-10.9 ¢/kWh (depending on technology); and coal with 90% carbon sequestration, 12.3 ¢/kWh (rising to 14 ¢/kWh at 30%). Among the non-dispatchable technologies, LCOE estimates vary widely: wind onshore, 5.2 ¢/kWh; solar PV, 6.7 ¢/kWh; offshore wind, 14.6 ¢/kWh; and solar thermal, 18.4 ¢/kWh.

    Weird, I’ve never had problems over the past 15 years or so and I’ve been using VPS servers exclusively. Maybe my providers were reputable enough.

    I realize my evidence is only anecdotal, but that’s why I started “in my experience”. Also, common blacklists are checked by the services I mentioned.

    In my experience, this is nothing more than an urban legend at this point. There are great standards, like DMARC, DKIM, SPF, proper reverse DNS and more, that are much more reliable and are actually used by major mail servers. Pick a free service that scans the publicly visible parts of your email server and one that accepts an email that you send to them and generates a report. Make sure all checks are green. After an initial day of two of getting it right, I’ve never had trouble with any provider accepting mail and the ongoing maintenance is very low.

    Milage may vary with an unknown domain and large email volumes or suspicious contents, though.


  • As part of an iterative test programme, many milestones were achieved. Perfection is neither expected nor desired at this stage.

    Sounds reasonable, except for the final bit. It’s just ridiculous to claim that perfection was not desired. Sensors provide the same data, investors will be happier and invest more, clients will gain more trust and spend more. It feels like the excuse some kid would come up with, who is lacking self confidence to stand by their limited success and claimed it was all intentio… oh.









  • Everyone keeps saying that but I just can’t see it. The only time my mails were rejected was because I didn’t know what I was doing at the beginning of my journey. Now, whenever I changed my stack or did some major updates the past 20 years or so, I just go to 2-3 sites that analyze my mail server from the outside and tell me if there is anything wrong. The free tier is always more than enough. Just make sure there is at least one service in the list where you send an email to a generated mailbox and have it analyzed. Just looking at the mail server is not enough to find all potential configuration issues.

    I aim at a100% score. It’s time consuming the first time around but later it’s just a breeze.
