There is wal-g that moves the wal files to s3 and you can spin up any number of instances off of that. Works great for catching up secondary servers

Have you tried switching it to a job queue where the GPU instances try to keep themselves busy. That way you can auto scale the gpus based on utilization. I find it easier to tune and you can monitor latency and backlogs easier. It does require some async mechanisms to the client but I have found it easier to maintain

I wonder how many audio conversations were overheard and uploaded during that moment.

Seems like an attack vector for forcing your devices to start recording the mic and transmitting it.

Even if it just takes down the wifi through maxing out internet connection or cellular network. Play a couple seconds of audio and gigabytes get uploaded.

If you have optimized your math heavy code and it is already in a typed language and you need it to be faster, then you think about the GPU options

In my experience you can roughly get 8x speed improvement.

Turning a 4 second web response into half a second can be game changing. But it is a lot easier to use a web socket and put a spinner or cache result in background.

Running a GPU in the cloud is expensive

Here is a quick test

The table of contents points to a single Json object that is 20ish gb compressed

I think it is somewhat like git's creation story. Sometimes a senior dev sees a tool that is close to ideal but needs to work a little differently than what the industry has built.

Databases are up there with encryption. Don't roll your own... mentality.

But sometimes they don't fit the problem your solving. Sometimes the data never changes so why have infrastructure for updates.

Having a big DB running all the time could be too expensive for your business model

Also it is good to be curious about "what is an index" and how does a parquet file look in hex editor. Why can't I write the underlying db table outside of postgres. Why are joins hard..

And then you discover your tools give you a competitive edge

Most of the time there are existing tools, but sometimes they don't.

Insurance price transparency can have 16gb of compressed JSON that represents a single object.

Here is the anthem page. The toc link is 16gb

They are complying with the mandate. But not optimizing for the parsers

There are some exciting ways to continue using the heroku build packs and Google cloudbuild to host on gcp. You can maintain git push deploys costs can be pretty inexpensive. The primary cost is around managed postgres.

It isn't the same as a free plan but can provide a very similar ease of use. My profile has contact info if you want more detail.

I enjoy being lefty. My grandfather was trained into being righty except for golf, so I noticed early on how things were not made for me and I had to do extra work. My father uses a lot of power tools and the extra dangers were apparent there as well.

Overall it has probably helped my programming as I had been thinking outside the box for longer than the righties.

sounds like we could use this for user attestation.

The tailscale client can be queried to convert from tailscale ip to email. This could be used to track who is using the VPN service and to sign them into the protected web app. Grafana allows header auth params for example

Dell precision 54xx laptops with linux are pretty nice but my more recent one had thunderbolt issues and the support didn't live up to the "linux first" support I was expecting. I have switched to the system76 and really like the Lemur Pro 14.

Fast walking with some hills is great. It also reduced my stress quite a bit as after 20 minutes I would stop contemplating/planning and just walk. Doesn't matter the weather and much easier to do

It may take volume first. But you can negotiate with stripe to get better rates. You take on more of the risk though.

maybe. We haven't had any issues with it over last year. The comcast outage last week probably affected more customers.

well written.

Things I would add to the Good side.

- ability to commit to multi year cpu/ram without upfront costs

- they can live migrate your vm to new physical hardware, so no need to have random reboots of your instances

- https load balancers allow traffic around the world to enter google network closest to user, this reduces handshakes and reduces comcast like outages to affect users.

the above greatly decrease my stress.

easily displaying many dashboards within your office is something that I haven't found any off the shelf solutions for. Our office has 20 tv's with chromecasts all displaying specific dashboards, but it took coding effort to get it to work.
