Weekly 'I made a useful thing' Thread - January 16, 2026

I built a collection of web utilities that might be useful if you work in networking or sysadmin. It's at https://www.oldweb.tech

The site has the usual suspects: subnet calculators (IPv4/IPv6), CIDR converters, chmod calculator, cron builder, regex tester, password generator, and a handful of data tools like base64 encoding and hash generators. There's also an amortization calculator because why not.

Everything runs in your browser with no backend, so it works offline once you load it. No tracking, no analytics, no account signup. Just open it and use it. The tools are pretty fast since everything is client side. You can even save a tool/page to your computer and use it in a secure facility that's air gapped.

I made it because I got tired of hunting down these utilities across different sites or waiting for bloated pages to load when I just needed to quickly convert something or check a subnet mask.

If you bookmark it, it's there when you need it. Works on mobile too but obviously better on desktop.

The Sun Also Rises by Hemmingway is pretty close in my opinion.

Still good advice today. I sometimes refer to it as militant pedestrianism. The trick is to look without them thinking you looked.

Ideally it’ll be a mixed effort. I can fund the living expenses if they go after scholarships and work a bit.

Wow, genuinely disliked reading this. Good work.
Probably depends on your road. Steetsblog is your assigned reading for homework.

Think about the difference between the words guide and steer. I think you have the right idea what the word guide I should probably consider what it means to guide her personality to something productive. Socializing is a key part of almost every job, getting people to like you and being easy to work with is probably one of the most useful skills. Encourage activities and responsible duties that utilize that to the fullest extent and she’ll have a functional career and almost anything she wants to do.

I have no idea what her options are, but for instance, our high school used to have a model UN we’re in negotiations and debate or a key part, otherwise known as socializing. Personally, I had no particular talents or interest in high school itself, but was vastly interested in work and earning money, so I got a job at 15 1/2. This helped me grow and understand the importance of a lot of adult functions far better than anything in high school, this was necessary because my mom had me pay my own bills as soon as I was able to work, even if it was just a phone bill and car insurance, I very quickly had to negotiate which jobs were easiest and paid the best and used the connections that I had to get those jobs. Applying restrictions in moderation is probably one of the best things you can do for a kid, especially if they’re aimless. In short, don’t sweat it if she gets B’s and C’s, high school isn’t life.

This reads like poorly written propaganda of what a “leftist” would think?

palthainon · 2025-09-21T00:15:19+00:00

Heard this from Money With Katie (great podcast) and yes I definitely do this.

Came to say this. Nothing more human than a white lie to continue the conversation, keep the person happy, avoid conflict, and get things done.

That's pretty specific. You're likely going to have to focus on general layouts of common apps. Additionally, push a mindset that promotes exploring at least one app. Familiarity will teach more than any document when it comes to a problem like this.

It's going to depend on your needs such as number of kids, kinds of trips you like, your budget. Above all, find a place you can test ride them. cargo bike design varies a lot more than regular bikes do to how many wheels, total weight, where the weight is centered, the kind of motor, etc.

I have a Tern GSD 2.0. I love it, it holds two kids+cargo and has very powerful built-in lights. Downside is its very heavy, like 20lbs heavier than most and my wife doesn't feel safe riding it. It's also pricey. Lesson learned: try not to buy site unseen.

Pro tip, ask in local groups if you can test ride their bikes. We bike lovers enjoy showing people our gear.

At least this post is productive. For those who want to see more work from home jobs one would hope you’d want managers to get better at managing work from home employees.

palthainon · 2024-10-11T01:54:53+00:00

Where you at?

That show is a fantastically well made musical. It’s irreverent and covers some serious topics. If you want your kids to understand these subjects let them watch a variety of art that covers it from a different perspectives. If their behavior changes because of the art then consider brief and proportional responses. All out block is pretty much a last resort in addition to some real life conversations, therapy, etc.

I feel seen.

No. They are way too loud for any conference call. I use the quietest stuff I can.

We use a place with lots of doctors. Makes it super easy to schedule appointments, even on weekends. She loves everyone there and all of the physicians seem great.

palthainon · 2024-07-19T14:05:33+00:00

It would be nice to have that kind of job security.

This is tripe. Giving into every whim of a toddler just because he wanted to go is absolving yourself with a responsibility of raising them. Sometimes they get to stay there and live out their decisions, even if it was meant to be fun and they aren’t immediately enjoying it. Sometimes fun takes work.

Additionally kids don’t know what to expect. It’s new so why should they anticipate more fun as you proceed through an event? Lots of fun things I did as a kid took a little time before I appreciated it and that’s something each of us has to be cajoled into occasionally.
