DavidKarlas··on Show HN: SQL-tap – Real-time SQL traffic viewer for PostgreSQL and MySQL
Could I put this into default docker-compose for developers, so when they work on project with micro services they can quickly inspect SQL queries if something weird is happening? How would this UI work with that scenario, feels like React frontend would better serve that purpose.
DavidKarlas··on Fast and secure translation on your local machine with a GUI
https://cordis.europa.eu/project/id/825303 seems to have a lot of info.
DavidKarlas··on EVs are lowering Bay Area's carbon footprint
Ye, because fossil fuel extraction and refining for lifetime of car is all roses and sunshine.
DavidKarlas··on Brazil Hits 92% Renewable Energy Milestone
Isn't this just cycling carbon in ecosystem? Same as planting tree on 100 year scale is pointless... I would imagine that hydro is ~neutral on 100 year scale, while coal is not, since we introduce carbon into ecosystem. What am I missing?
DavidKarlas··on AvaloniaUI: Create Multi-Platform Apps with .NET
Eco probably means ecosystem, which I assume it means lack of UI Controls like Maps view, Graph/Charts for visualizing data, Date pickers and other stuff they you can get from vibrant UI ecosystem. But I think some of this stuff is already handled in Avalonia ecosystem like https://github.com/Mapsui/Mapsui, https://github.com/beto-rodriguez/LiveCharts2 and few others...
DavidKarlas··on Solar and wind to top coal power in US for first time in 2024
My biggest problem with solar and storage is not day/week energy management we can solve that easy, add more batteries, pumped hydro, use car batteries, incentivize customers to use electricity when sun is up... All easy problem compared to seasonal storage.

Where do we get enough renewable electricity on cloudy week in December? Synthetic gas/oil produced in summer? Anything more promising?

DavidKarlas··on DIY Home EV Charger
Well there is also software... I really liked go-eCharger HOME+ 11kW, because it has 3-phase "European connector" and I can go almost anywhere in europe take it with me and charge there... I usually take it with me when I go to my parents so I don't have to stop on way at fast charger... Anyway.. I paid 650EUR, well above price of parts cost... But mobile app and firmware keep getting updated and it keeps getting features like "charge from solar" better scheduler, also supports multiple chargers to limit total amps...
DavidKarlas··on Sam Altman, Greg Brockman and others to join Microsoft
I will never forget something I read in his "Hit Refresh" book(I'm Microsoft employee)... He wrote something along the lines, Office should write best app for iPhone, Mac or even Linux if that helps them grow. They should not help Windows sell Windows copies by doing better Office features on Windows, it is up to Windows team to make Windows best operating system, it should not rely and keep back Office team... This makes Windows and Office better, because it allows Office to be free and do what they need to grow, and it forces Windows to improve OS and not rely on others... Just one example where CEO can help teams grow...
DavidKarlas··on .NET 8
C# design team is ~5 talented well paid engineers who think how to improve language for past 20 years, every week and don’t let flawed features in and can spend years on how to add async/await, nullables, SpanT and many other features so whole language makes sense and is joy to use. And they have another ~20 engineers implementing features in Roslyn making sure performance of IDE and compiler is acceptable and bug ~free. Unfortunately not many languages can afford that…
DavidKarlas··on Detroit wants to be the first big American city to tax land value
So my house is worth 500k, someone looking for house in range 500k-700k, really really likes my house and just kicks me out for 750k? Sounds like terrible idea.
DavidKarlas··on There's a new map style on OpenStreetMap.org
I just wish it displayed buildings at zoom 16(today at 17, while default OSM renderer at 15). And similar for addresses displayed currently at 19, I wish it was at 18, while OSM default renderer displays at 17.
DavidKarlas··on InfluxDB Cloud shuts down in Belgium; some weren't notified before data deletion
Why did you feel need to send 3 emails, and not just 1? Is it because you find emails not reliable enough?
DavidKarlas··on StarCoder and StarCoderBase: 15.5B parameter models with 8K context length
Sounds same as when I started codding, hallucinated some code, compiler told me it is non-sense, and eventually I understood most of the rules... I still mess it up...
DavidKarlas··on GPT-4 writes an entire 115 page fiction novel
I was thinking few days ago, In 20 years we will probably be able to say something like “Make a TV show that is mix of Game of thrones and Lord of the rings, has 4 seasons with 10 episodes each and main character is played by Tom Hanks and co-star Sandra Bullock” and you just start watching, probably tweak it as you go, saying more fighting, explore more story in desert about dragons…
DavidKarlas··on Scheduling My Electricity Usage
I set my heat pump to only work between 9:30 and 16:00(since I got floor heating it keeps house warm over night and concrete works as storage). I set 200L boiler(inside heatpump) to heat water between 12:00 and 14:00 and we never run out of hot water. I charge car either between 12:00 and 15:00 or between 01:00 and 05:00, depending being sunny day. Dishwasher is on timer to run at 01:00. Washer runs around 12:00. All this is doable when working from home.

Hardest part avoding peaks is cooking diner… But even then induction is pretty efficent.

DavidKarlas··on Solar canopies on parking lots
Also water cooling air under panels improves performance…
DavidKarlas··on What is the cost of a cashless society?
Working with cash is not free either, you need security truck and drivers that come pick up cash at end of day... Afaik in EU debit cards are capped much lower than 3%.
DavidKarlas··on Saskatchewan, Ontario to roll out mini-nuclear reactors
If you calculate 300MW/240k homes, it comes out at 1.25kW per home which is not enough for peak demand...
DavidKarlas··on Large-scale ‘sand battery’ goes online in Finland

DavidKarlas··on Show HN: RootMy.TV
I’m aware of shortcut long press # keys, but that only works once TV is powered on…
DavidKarlas··on Show HN: RootMy.TV
Could I change functionality of buttons on remote with this? For example Amazon, Netflix or “Movies” with different app?
DavidKarlas··on OsmAnd 4.1 adds inital support for Android Auto
If such datasource becomes available in future we will just create osmV2 from it and be done… I’m working on import for my home country(Slovenia) for buildings and addresses, and I like to think our GIS is well organised and maintained, and yet I find things like demolished buildings still in GIS or new buildings not added… Relocated buildinga/addresses…
DavidKarlas··on Germany is closing half of its reactors before the end of the year
Thanks for that insight, I did find it weird why they only use 2/3 of nuclear capacity...
DavidKarlas··on Germany is closing half of its reactors before the end of the year
People keep saying that but looking at https://app.electricitymap.org/zone/FR it seems reverse... That is probably happening in summer at nights...
DavidKarlas··on “Our house is running on a repurposed battery from a wrecked Tesla Model S”
All this is pretty interesting but it is a bit click-baity tweet... In one of replies he states "when all else fails, a propane generator kicks on, but rarely."

DavidKarlas··on 10 years of whatever this has been
Nice example of American football, since players have brain injuries, should we ban it too?
DavidKarlas··on Rivian valued at over $100B after biggest IPO of 2021
I read "pop corn" as "dot com" :P
DavidKarlas··on Macron says France will build new nuclear energy reactors
I have been watching https://app.electricitymap.org/zone/DE?wind=true&solar=false for past 2 days... Winds weak, yet even when electricity was expensive yesterday around 6PM, Germany was pushing to France, mostly coal generated electricity... Someone cares to explain?
DavidKarlas··on .NET 6 Released
.NET is sane now... .NET 5, .NET 6, .NET 7... all cool, no more confusion going forward... .NET Framework(full Windows only Framework) is .NET Framework 4.x, stuck there forever only security patches...

Only remaining confusing part left in ecosystem is "ASP.NET Core", because even though .NET got rid of Core, latest version ASP.NET didn't
