Tidal AI Policy 24 days ago

It would be a shades of gray situation, but I think of this performance by Skrillex where he is mixing live, and thats what I would expect from a live EDM performance. There should be a line between a EDM artist, and a DJ

Tidal AI Policy 24 days ago

I just want Tidal and Spotify to give me the option to fully opt-out of AI generated music. I don't want it mixed in with my music. If others want it great, but I want the option to not engage with the content.

Brave Origin 2 months ago

This is precisely what I want from my browser, let me pay directly for a critical piece of software, and remove myself from the Surveillance Economy, without having to settle for some second class product.

Brave has been, in my opinion, the best browser for a long time, and I am happy to be able to pay for a product that I use without worrying that its going to need to sell its soul to continue to provide support

You make a compelling argument, but thankfully I have data to back up my anecdotal experience

This comparison shows them neck and neck https://benchlm.ai/compare/claude-sonnet-4-5-vs-gemma-4-31b

As Does this one https://llm-stats.com/models/compare/claude-sonnet-4-6-vs-ge...

And the pelican benchmark even shows them pretty close https://simonwillison.net/2026/Apr/2/gemma-4/ https://simonwillison.net/2025/Sep/29/claude-sonnet-4-5/

Also this isn't a fringe statement, you can see most people who have done an evaluation agree with me

The Gemma models are at this point. A 31B model that can fit on a consumer card is as good as Sonnet 4.5. I haven't put it through as much on the coding front or tool calling as I have the Claude or GPT models, but for text processing it is on par with the frontier models.

Just wait until you find out the benefits of taking them away from kids altogether! Phones are a mental health hazard for children, there is no benefit for them having a phone. The only downside is they feel left out when their friends only want to sit around and scroll TikTok, and can't manage to have any in person interactions without their face in a screen.

None of my children have phones, and when they do get one, it will be when they are driving and will be a dumb phone for sending text messages and making calls.

I really wish Graphite had just gone down the path of better Git hosting and reviewing, instead of trying to charge me $40 a month for an AI reviewer. It would be nice to have a real first class alternative to Github

Just Text to speech seems like its largely solved on pretty much every compute platform. However I have found a huge gap going from independent words being transcribed, to formatted text ready for an editor, or further processing.

If you look at how authors dictate they works ( which they have done for millennia), just getting the words written down is only the first step, and its by far the easiest. I have been helping build a tool https://bookscribe.ai that not only does the transcription, but then can post process it to make it actually usable for longer form content.

D1 is fine when it fits the use case, but most of the time I just want Postgres that I will use for absolutely everything. It has happened often enough that I have tried to make systems work with other storage systems, and eventually just give up and revert to Postgres. Every time I just start with Postgres I don't have issues until it turns out my laziness has caused a performance problem, and those I can fix.

Astro on Cloudflare workers has been my goto stack for multiple years now. I am very happy with it, and hope this makes the integration stronger.

Now we just need Cloudflare to buy one of the DBaaS companies so they have a solid relational offering.

No, my wife and I discussed putting them into traditional school as they got older, but now that they are older, they have all strongly requested to remain in their homeschool co-op. I think the biggest reason is they have a good group of friends that they connect with, and have been their class mates for multiple years. So there is a strong desire to continue in the program with people they know.

My kids are part of a co-op where they meet once a week and in this co-op they share some elements of their curriculum with everyone else, they spend one day going over the weeks assignments along with 8-10 classmates, and then during the week they are at home doing their work. As they have aged their school work now has a lot of collaborative elements, so my oldest is actually meeting with kids from his co-op almost daily to go over group projects and assignments.

Additionally they have a lot of extra curricular activities they participate in ( sports, music, church youth group), that also gives them a lot of socialization time with others.

When I recently switched jobs, one of my requirements was I had to remain remote, for at least the next few years, so I could remain at home and help with my children's education. I don't think there is enough money in the world to convince me to change back to public education. Aside from the benefits everyone mentions like a much better education, having so much extra time with my children is a priceless gift that I wish we as a society could give everyone.

Also its given me the chance to learn things that I missed during my primary and secondary educations. Going through each proof in Euclid's Elements again has been a lot of fun, and its been long enough that I have forgotten most of them, so the thrill of discovery is real for me too.

If you can make it work, you should make it work, even if that means moving to a lower CoL area, there are a lot of small towns in the US that have excellent amenities, and are great places to raise a family.

Depending on where you live there are many options. In my school district home school kids can join any club or team offered by the public school system where you reside. Additionally there are numerous non-school related clubs and activities all over the place. My kids could play music with the local school district, with a musical education non-profit that is prolific in our area, or ( where they do play music ) with private lessons that have group classes, bands, and performance opportunities.

This is long term the right choice. Tesla has the best software competency of any manufacture and if you want to compete with them you can't offload major bits of functionality to a third party. At this point in our software journey in cars, user experience is everything. If I can't have a car that I walk up to with my phone in my pocket and get in and drive, with automatic doors unlocking, and all my settings automatically set to me, then its a net loss.

I can barely get my phone to reliably pair with my Ford, but my Tesla always picks up me as the driver and just does everything correctly. Rivian needs to offer me that same level of polish to be competitive.

Litestream v0.5.0 10 months ago

I tried to go the litestream route on Fly.io, but there is too much that needs to be done to get it working. Specifically I was hoping scaling would be a lot easier, but master election kept breaking for me causing the whole app to not be able to come online. I just moved to Fly's managed postgres and called it a day.

Their managed postgres has gotten better, but its still a little sparse, so after about 6 months using it I am going to just take my DB to either Supabase or Planetscale.

I would just point out that its Hosted Postgres. If your looking for a how I think you have the wrong mental model. Its hosted Postgres, there are some nuance there as to why it would perform differently from RDS on Amazon, or CloudSQL on GCP, but its not some novel new technology that needs a long description.

If you are interested in their new technology that extends on hosted postgres check out Neki https://www.neki.dev/

I haven't explicitly tested how it handles TOASTed column's, but since there is an upcoming RC I will try it out next time. I don't generally like using JSONB/text columns for very large rows as they have other performance problems on the DB like causing lots of WAL write overhead.

In term of other workloads it might not be great for, all my testing has shown a great improvement in every workload I have thrown at it.

OrioleDB isn't a separation of storage and compute, its a more efficient storage engine for Postgres to replace the existing HEAP engine. This is like how in MySQL we could swap MyISAM for InnoDB and eventually RocksDB.

I did some benchmarks on it previously to show how much of an improvement it gives over the stock HEAP engine

Not being able to read this article I can only speculate as to what it actually says, but I imagine it is a direct response to Joe Rigney's book "The Sin of Empathy" https://canonpress.com/products/the-sin-of-empathy

One of the criticism that Joe addresses in that book, is that if he used the term "The sin of anger" no one would critique his claim since we don't hold anger on a pedestal, even though there is righteous and sinful anger, but we have exhalted empathy so much that anything that says we shouldn't adopt "untethered empathy" is looked upon as a attack on all empathy.

It looks like this is one of those attacks that tries to totally discredit the idea that our compassion should have a basis in truth, and when we abandon that basis we are in fact committing a sin.

The way funding was allocated is entirely broken, and it was the biggest problem with doing anything in the government. Our budget process at the federal level is entirely broken. Congress tries to micro-manage the budget to get their cut of funds to their sponsors, and their is no political appetite to have a more reasonable budget process ( like Congress approve top line budget, and lets the agency choose how to spend the money ). The Defense Finance and Accounting Service (DFAS) doesn't work for inter agency procurement, and IMO is not a good system for any kind of procurement. The Federal Acquisition Regulation (FAR) should be thrown out, as it has proven its self to be worse then having literally no rules at all. All the rules about Veteran Owned, and Small Disadvantaged Businesses are just mechanisms for fraud. Companies would "dissolve" and then new companies would form that could win those bids, and then they would hire everyone from the large company that just dissolved.

I worked for the USDS in the early days and I am very familiar with 18F, and I don't think your comment tracks. There were lots of issues with agencies using 18F, and not much of the federal IT spend migrated to 18F during its 10 year history, even though most of the products they launched were good.

Even USDS teams didn't always take up 18F on its products, and instead would utilize outside contracts for a majority of their projects. Realistically the government needs to do better then 18F was doing and there are many reforms needed to actually have a paved road agencies can drive on.

I don't think this article is a good faith analysis of Homeschooling. Clearly the author was home schooled and had some concerns with how they were instructed. With that in mind the arguments that are brought up are very much ignoring the breath of options that are all covered under "homeschool". There is far more diversity in the home school world beyond academic overachiever and religious fundamentalist.

Fundamentally home school allows children to be taught in a way that is appropriate for them, and with the speed and oversight they require. Something that you can't really do in a corporate school setting. All three of my children learn at different paces, and require different amounts of involvement. They all require much more involvement then they ever got at traditional schools, and they have at times progressed through their coursework much faster or much slower then the "average" pace.

It is true that if you have a child that is a academic prodigy they will greatly benefit from homeschooling, and its true that keeping your children in your home can allow you to be the greatest influence in their moral and social instruction, but its also true that even "average" students will probably do better with 1-1 instruction from a parent who is well equipped then they will with a teacher who might be better trained, but is ill equipped to actually instruct each individual pupil.

As for the main point that somehow this is some form of elitism where homeschool families don't want their kids around the common rabble. The homeschool families I know range from households where both parents hold post secondary degree's, to ones where the parents got GED's, and the career expectations are suitably broad for the kids being schooled. This stands in stark contrast to traditional school which ranks its self on how many kids go to 4 year colleges, and looks down on anyone who would join a trade, or be a home maker. This is literally my biggest complaint with school in the Bay Area. If your kid didn't get into Berkeley or Stanford your household was perceived to be a failure, and if they had any desire to do something other then be a Product Manager at a FAANG then they were going to be forced to live at home forever or move to another state.

If you have a child on your policy, and you have a collision on your policy, then your child will be required to be included in that policy. Insurance companies don't accept that you can live in a household, but won't be allowed to drive the new car, so they will charge you like the child is driving the new car under any circumstance.
