Estimated taxes
I forgot to pay my taxes. Yes, I know it’s September, and no, I’m not talking about my annual tax return. For the last few months, I forgot to pay estimated tax, which is a thing that some in...
Network traffic analysis
In the last 8 months, I’ve captured and analyzed 4.4 billion network packets from my home internet connection, representing 3833 GiB of data. Life basically occurs via the internet when you’r...
Hisashiburi
Hey reader, it’s been a long time. I hope you’re doing well. You haven’t heard from me in a while, but it’s not because I’ve been busy. If anything, I’ve had more free time this year ...
Undeletable data storage
I buy stuff when I’m bored. Sometimes, I buy random computer parts to spark project ideas. This usually works really well, but when I bought a 2TB external hard drive the week before thanksgivi...
The case for pro-death
Political polarization is a hot topic right now. People say it comes from misinformation or social media, but I think it goes deeper than that. So today, I’ll be playing devil’s advocate and ...
Yet another Mac
Last year, I sold my laptop. I owned it for about 15 months, and in that time, I took it outside on maybe three occasions. The laptop hardly left my desk. I didn’t even open the lid, because mo...
Tragedy and loss
Among my favorite anime, there are a few that I never ever recommend to others. It’s not the weird ones. It’s not even just the ecchi. I’m talking about shows that are so precious to me tha...
A data backup system of one’s own
One of the biggest solo projects I’ve ever completed is Ef, my custom data backup system. I’ve written about data loss before, but that post glazed over the software I actually use to create ...
Catching up
Hey reader. Happy new year? It has been eight months since I last posted anything on this blog. Is that the longest hiatus I’ve ever taken? Maybe. Probably not. I enjoyed writing those longer p...
Pretty good computer security
I don’t cut my own hair. I can’t change my own engine oil. At the grocery store, I always pick Tide and Skippy, even though the generic brand is probably cheaper and just as good. “Well, th...
The rules are unfair
It’s 11pm. I should go to sleep. But sometimes, when it’s 11pm and I know I should go to sleep, I don’t. Instead, I stay up and watch dash cam videos on the internet. Nowadays, you can pop ...
Computer programming
I think I like being a computer programmer. Really. It’s not just something I say because it sounds good in job interviews. I’ve written computer programs almost every day for the last five y...
Net neutrality
I don’t know a single person who actually supports the FCC’s recent proposal to deregulate broadband internet access by reclassifying it as an information service. However, I also never did m...
Feel bad
The hardest truth I had to learn growing up is that not everyone is interested in the truth, and maybe that’s okay. I’m not talking about material truths like the mounting evidence for climat...
The serving path of Hubnext
I’ve always liked things straight and direct to the point. But I feel a bit silly writing that here, since most of my blog posts from high school used a bunch of long words for no reason. My wr...
Something else
I talk a lot about one day giving up computers and moving out, far, far away to a place where there aren’t any people, in order to become a lumberjack or a farmer. Well lately, it’s been not ...
Training angst
Have you ever used Incognito Mode because you wanted to search for something weird, but you didn’t want it showing up in targeted ads? Or have you ever withheld a Like from a YouTube video, bec...
Data loss and you
My laptop’s hard drive crashed in 2012. I was on campus walking by Evans Hall, when I took my recently-purchased Thinkpad x230 out of my backpack to look up a map (didn’t have a smartphone), ...
Life lessons from artificial intelligence
If you speak to enough software engineers, you’ll realize that many of them can’t understand some everyday ideas without using computer metaphors. They say “context switching” to explain ...
The data model of Hubnext
I got my first computer when I was 8. It was made out of this beige-white plastic and ran a (possibly bootlegged) copy of Windows ME1. Since our house had recently gotten DSL installed, the inter...
What’s “next” for RogerHub
Did I intentionally use 3 different smart quotes in the title? You bet I did! But did it require a few trips to fileformat.info and some Python to figure out what the proper octal escape sequence...
Child prodigy
I watched a YouTube video this morning about a 13 year old boy taught himself to make iPhone apps and got famous for it. He took an internship at Facebook and then started working there full-tim...
Email surveillance
There’s a new article in the SF Chronicle that says the University of California, Office of the President (UCOP) has been monitoring emails going in and out of the UC system by using computer h...
Website updates
Last December was the biggest month for RogerHub ever. We served over 4 million hits, which consumed over 3 terabytes of bandwidth. By request, we released the 6th calculator mode, “lowest test...
Grown ups
I haven’t posted anything to my Tumblr blog in 649 days, but in that time I’ve gained maybe 50 new followers, and they’re all strangers. I don’t think any of them are bots either. They fo...
Notes and reminders
This is Notes.app, which I use to save rich text and organize ideas. I like it because it’s not a website, it’s a native OS X app. And because it opens in a small window that fits on the side...
Sticky note
1 I put this sticky note on my window on the first week of school. I needed pictures of something where the foreground was close by, but the background was far away. It was for the project I was ...
Catching up on this year
Welcome back reader! I’ve been gone for more than a year, and a lot of things have changed. I haven’t stopped blogging. I was just scared off of this blog, because of all the visitors spillin...
Miscellaneous things
Last friday, there was an outdoor concert on campus and I went with some of the people I lived with in the dorms last year. I hadn’t heard of either of the bands performing, but that didn’t w...
Dead man's switch
A few years ago, I started toying with the idea of leaving behind contingency letters in case I died an early and unexpected death. I usually like being fairly well-prepared for all kinds of data...
