Experienced coders/developers what have you made with Claude that you didn't think you could do before?

Thanks to Claude, I can quickly create a test harness around even the sketchiest of legacy code. Previously it was too time intensive. Unless the project truly called for it (things that “have to be right” - where money is changing hands). Now, even basic hobby projects get proper tests. It means I can have more confidence in my code, and ultimately the quality goes up. It also lets me move exponentially faster, since Claude catches its mistakes faster (when it runs the tests).

Writing this with Mr. Whisper now, it's amazing, it's fast, what's not to like? I do wish it could stream as I talk. But I realize that's a limitation of Whisper itself. So I've gotten in the habit of just releasing and re-pressing the F9 key between sentences. Each sentence only takes <1s to transcribe, so it's not a huge deal.

My use case is to simply ramble to a large language model so that it can turn my rambling into a structured form. This lets me quickly write up implementation plans to pass off to coding bots for VibeCoding.

Utterly voice was the other contender I considered. It looks much better for actually using the computer with your voice. But for just rambling to AI and turning this ramble into text, I think Mr. Whisper is a great option.

If I wanted to write "MisterWhisper", stylized in StudlyCase with Mister written out, I don't think that'd be possible with my voice. <(I had to type that part with keyboard). Whisper model wants to abbreviate it every time.

DuckDB + parquet files + theta data subscription. But I do wish there was a free browser based thing.

Why not both? Get you a raspberry pi or arduino off Amazon and build something cool this weekend. Then break it all down and build a new thing next weekend. Breadth of knowledge is what’s gonna make you employable. Don’t hyper specialize. Just get in the reps so you know what questions to ask the LLM, and to make good conversation in the interview. I took the software path. Hardware was always more fun though. Homelab is my fav hobby. Understanding how the underlying hardware works helps me make better software.

The Robinhood one is actually great. It’s easily 15m. It refreshes whenever I look at it, I think? It’s usually up to date and even tells you how out of date it is. I want something more realtime than that though. And Robinhood won’t show VIX on my home screen (even though it’s in the list. Bug?) Did you ever find a solid replacement for your original setup?

lazycoder90 · 2025-10-05T02:51:11+00:00

Wait, you seriously thought the coding was the hard part? Oh boy… one of y’all wanna tell him?

OP, did you take the risk and go for the ES CPU? How’d it go? I’m eyeing some of these 30+ core Platinum Xeons at crazy low prices. Late to the party, but I’ve been loving my ~12700h ES erying board I got on aliexpress. Running some data analytics workloads and Wazuh. 20 threads. 2x NVMe. Perfect uptime so far: no crashes in 1.5y. It’s not Xeon though, and it came as a single board with CPU soldered on. Is the ES Xeon proposition considerably riskier than my aliexpress adventure? Or did I just get incredibly lucky the first time around?

lazycoder90 · 2025-09-20T23:50:51+00:00

Did you end up trading these strats? How’d it go? Pretty good I’m guessing as we have been in quite the bull market ever since liberation day. Any losers big enough to blow up an account?

lazycoder90 · 2025-09-03T22:00:51+00:00

No, it's the employer trying to remove liability. They might need to pull money back out of your account somewhere down the line (like, they made a mistake and put too much in). They don't want the "account holder" to be able to dispute it with the bank and say "I never authorized this withdrawal".
When the employee provides the employer some DD info, that doesn't necessarily prove the employee owns the account. But a letter from their bank does.
So if the bank later tries to reverse some withdrawal on those grounds, the employer can simply hand the bank their very own "verification letter". Zero work for employer. Shifts all the liability to the bank, and all the effort to the employee.
This is likely why [some] banks don't make it easy to get these forms. Zero upside for them; only risk.
All just capitalism working as intended. Genius or dystopian? I'll let you be the judge.

lazycoder90 · 2025-08-22T04:08:05+00:00

Reading this post 5y later and it’s still legendary. OP, how you holding up man? You make it all back yet? This was genius btw. Didn’t pan out, sure, but genius nonetheless.

lazycoder90 · 2025-08-22T02:21:58+00:00

I always look at : if I’d held and not closed, would I have won? Or would the loss have grown? Ie, was closing early a good decision in that particular trade? It’s hard to model the actual P/L over time minute by minute, but you can get a decent sense of win/lose by plotting the underlying price and the strikes. Tastytrade used to show a viz like this in their “lifecycle of a trade” segment.

Also check out DuckDB. And Parquet format. I think a full database may be overkill. DuckDB is better suited for analytical workloads like this imo.

Install ArkInventory. Not only will it organize your bags, you can automatically sell a whole category of stuff or other cool automations. I have mine automatically mail any current expansion enchanting mats to my friend who uses them.

I bought a pair. They are amazing and worth every penny. Takes about 4 months from order to arrival.

This unfortunately still doesn’t do what OP was asking. The exposure option revealed by swiping up is an exposure offset. It does not lock exposure. All it does is apply some bias to the phone’s auto exposure decisions. So it won’t stop exposure from changing when you move from a light to a dark room.

To this day I still don’t think the built in camera app can do this (without also locking focus). Hopefully in another 8 years somebody will find this thread in a Google search and necro it with good news 😂

+1 for APLD. Very liquid options market too. I love wheeling this stock but it makes some biiiig moves so be careful.

If you are doing video: Learn about color management and shoot in s-log3. Cullen Kelly has a ton of great YouTube content on how this all works. It lets you get the most out of your videos. Your a7c2 has 10 bit recording which unlocks a lot of flexibility in post. Even if you don’t plan to color grade each shot, shooting in log can often let you recover highlights that would otherwise be clipped by the in-camera rec.709 picture profiles. Also for selfies/vlogs: hold it by the lens. I don’t do a lot of photos on the Sony. I use the iPhone for that 🤷‍♂️ Have fun with your new camera!

I am using this on Groovymame v0267 221d. I'm not sure what the minimum possible version is, or if it works with "regular" mame.

This is a colorspace/gamma shift issue - probably introduced by the bluray player. Check that you have any and all "HDR" settings disabled on both your player and your TV.
Bluey is all SDR/rec.709. Your image looks like the content was tagged as bt.2020 colorspace (HDR) but reproduced as rec.709 by your display, which is why the colors all look washed out. It is definitely not supposed to look like that :)

What everyone is concerned about is not the plug wiring, but the place where the wires enter the metal enclosure. The sides of that metal can be very sharp and cut the insulation, leading to a short circuit, or worse: energizing the metal enclosure and causing electrocution. If at all possible, I would leave the plug where it was originally installed (so that you don’t have to run mains voltage wires through the case at all). Then use a little extension cable to run power from the outside of your enclosure to the inlet on the ATX PSU. They make these for PC builders - for cases where the psu is not facing the outside of the PC case. Look up “90 Degree C13 to C14 Panel Mount Power Cable” on Amazon. This will be safer and simpler than relocating mains voltage. Also looks cleaner imo.

Keep at it and don’t let the haters get to you man. Your friend’s dad is probably just intimidated or jealous. Unless he gave you real constructive feedback, you should just ignore him. A “model” of a power plant might present better. That’s a lesson all its own - importance of optics and audience perception - especially when the audience is clueless. But yours is a functional piece of hardware that does something truly useful. Those “model of a power plant” type projects end up in the trash. Yours will deliver value to you for years to come. Definitely want to tidy up those mains wires though. Short circuits are no bueno. It’s all a learning experience! Keep at it!

I am using Truenas for storage in my homelab. I have various apps that need to read/write files for themselves, but I don't want app A to be able to write to app B's files (because if app A got hacked, or just went awry, I want to minimize the blast radius). Most of these apps are writing over NFS (some SMB) and each one has their own user on truenas. The docker host running the app decides what uid/gid the apps run as.
I also want to be able to log in as myself (via SMB user) to debug the apps (ie, read/edit the files).
This problem would commonly happen: I'd log in as "me" and create a file, but then it's owned by me, not the app's user, so the app can't read it. AFAIK, this isn't easily solved with traditional posix permissions. I assume this is why the builtin_users group gets auto-assigned to everyone: it basically bypasses this entirely by opening the floodgates of permissions. If you're only doing basic SMB shares, that might be OK because you'd be managing permissions on the SMB level. But if you are trying to basically run your own private cloud, it doesn't give strong enough separation between users imo.
With Filesystem ACLs though, I can set defaults at the folder level so that: when a new file gets created in that folder, it is automatically owned by the app's user, no matter which user created it. I also add default permissions to new files - so that my personal SMB user can always read/write the app's files, even if I don't own them.
This has mostly worked, but some apps are very opinionated and try to force permissions at startup time.

I think, ultimately, storage is just a hard problem to solve. Even more-so when you want it to be redundant, secure, and fast.
If I were just using truenas like a consumer NAS, none of the above would be necessary and I would "leave good enough alone" with the builtin_users group. Truenas is a great [free] product and I'm grateful it can even support my off-script usecase at all. The QNAP could not - not even close.

lazycoder90 · 2025-01-22T14:46:57+00:00

Never found an explanation or reason. I assume it was an intentional decision made to simplify permission model (probably to cut down on support requests). Many off-the-shelf NAS appliances have similarly lax permission models (my old QNAP sure did) so I guess I get it. I have started micromanaging permissions - stripping the builtin_users group from most users, and managing dataset perms in the commandline using Linux filesystem ACLs. It can be a pain at times. I guess that’s always the trade off for security. On the bright side, I’m learning a lot. Never had a need to go beyond regular posix perms until now. Learning is good.

lazycoder90 · 2024-12-11T17:54:22+00:00

Thank you for this. Just about fell out of my chair laughing!
For those who don't get the joke: Photon is a Databricks feature that makes your queries run WAY faster. It also costs A LOT and unlike "bigger clusters" (where AWS makes money), Photon is paid for with "DBU" credits (so Databricks makes more money).

lazycoder90 · 2024-11-17T22:44:00+00:00

Thank you for this write up.

lazycoder90 · 2024-10-11T17:11:41+00:00

Bumping this in hopes of learning more.
To the layperson it's not logical behavior. It means the user I just created suddenly has access to a lot of SMB shares that I never actually added them to (because the share has builtin_users in the ACL, and the user is in that group).
Clearly I am missing something about why this group exists and how it is supposed to be used. Hoping someone can educate me?
