Ask HN: What kind of side projects are you working on?

110 pointsby 12y ago

12y agoHN ↗

An open source stream processing framework (https://ghostream.com) - it isn't really ready for the limelight yet, but you can find the code base on github (https://github.com/ghostream/ghostream) - final steps on the to do list are a few more example projects, a couple more functional operators and to polish up the documentation.

It has hit the 80-20 scenario. The last 20% is taking 80% of the time :)But it has let me quickly prototype a few little ideas (http://jamielewis.me.uk/posts/2013-11-03-Mapping-Earthquakes...)

12y agoHN ↗

Slick. Aside from the issues listed in github, what is taking 80% of the time? Did you expect the 80-20 split?

12y agoHN ↗

Honestly, part of it is motivation. I keep getting distracted with other things.

I expected it to go the 80-20 way, the initial ideas are not new ones, I have been building similar frameworks for a few years.

The time is mostly spent on the more difficult problems like "How should operators hang up when the program is closed?" " Should the program be expected to close?" "Should there be a global context object, or a default one" "Should an operator have a window by default or not"

There is no right answer, so its just a case of sucking it up and implementing something, seeing if it works, and going from there.

Plus the side escapades with earthquakes and space weather and irc channels - although implementing these little things does drive the bigger project.

I am hoping before the end of the year I can hit something I feel comfortable slapping "1.0" on and move onto something else for a while and use it as a base for working on some other ideas I have.

I'm making an online store in Rails for a specific target market (have to be vague). I'm building it mostly on my own and I'm looking for a second developer to help me out.

12y agoHN ↗

would love to learn more.. feel free to ping me, contact info in profile.

12y agoHN ↗

I am tired of repeating this again and again, so I am doing some yak shaving and creating a hosted rest service for managing user accounts and authentication. I will use it as basic infrastructure for future projects.

12y agoHN ↗

Rather than a hosted/solution - I would be think a program language specific (node/php/java) solution would be more useful. For example - something like $199 for lifetime use for account/oauth/etc system that you can use on any project. Maybe even have additional "packages" like invite friend, etc. Just a thought.

12y agoHN ↗

Scala tutorials (http://scalatutorials.com) - it's a "try scala code in your browser" (powered by scalakata.com) and has a basic tour at the moment, but I'm working on making it more like try ruby / codecademy, much more work than I thought by the way

12y agoHN ↗

Nice design and a great resource. Unicode is a complex beast, and making it easier to navigate and understand is a worthwhile goal, if only to improve how Joe Programmer deals with non-English text.

I've just started a site that aggregates open public transit data feeds. It lets you quickly see differences between feed versions, discover new feeds, and I'm working on APIs to easily bring in better real time data into apps

http://transitfeeds.com

12y agoHN ↗

Interesting - I'm working in this area too; more on the consumption of transit feeds - have noticed in the UK at least that there are a ton of T&Cs thrown around these feeds, do you think you have any issues repackaging like this?

12y agoHN ↗

It's definitely on the todo list to categorically make sure I'm complying with each feed. I think the biggest thing I'll need to change is perhaps to not allow download the zip of the most recent feed.

Can you share what it is you're working on?

A columnar time series db with an lmdb backend - I have only just started and it us quite a struggle.

A map / tile server written in go. So far MapBox' mbtiles work.

This came from a peculiar interest of mine, whether my city needs yet another underground parking garage. So I started to scrape the public rss feed of the parking system. I have some gigs of data by now and RethinkDB is not as performant as I hoped it would be. There is no real query optimization as of yet.

What I want to visualize is whether you can find a parking spot at a certain point in time and reach a spot, for instance a shop, within a certain threshold by foot. In short, if you want to shop at XXX will you have trouble finding a parking spot?

12y agoHN ↗

This is really nice. I would love to have the option of displaying a galactic coordinate grid and other bearings, and perhaps labels on some notable stars.

Great work.

Kitten, a programming language based on zero-cost abstractions (https://github.com/evincarofautumn/kitten). Competing in the same space as C++, Rust, and Nimrod. Statically typed, type-inferred, stack-based, higher-order, GC optional, with an effect system to manage side effects. Very much a work in progress, but you should stow it in your brain as a systems language to try in the future.

Cool map. Edmontonians don't generally like their city referred to as "Deadmonton". However, the nickname rings true on so many levels. Good luck with your move. Is it soon?

12y agoHN ↗

Thanks. Hmm the crime in your city is not that out of whack compared to the Canadian average. It actually made me feel safer about the city and will make house hunting easier.

The move shall be in about 10 months time. Am in the process of reviewing the different startups in the city currently. Are you involved in one?

12y agoHN ↗

I'm glad you're doing the research before taking the leap. There are lots of safe neighbourhoods and only a few I would avoid. Let me know if you have any questions about city.

Unfortunately, I'm not involved with any startups at the moment but would love to get involved with the right one (take a leap of my own). I moved back to this city about a year ago after being overseas for six years. I rushed the move due to family reasons and didn't properly set myself up in that regards. I have the right personality, but I'm not confident in my skills. I need to find a company where I can learn as well as contribute and flourish that way.

I hope you find something that suits you. Are you thinking of joining an existing startup or doing something on your own?

12y agoHN ↗

Is there a way to contact you? Your profile does not say.

12y agoHN ↗

Of course. You can reach out to me at j.bryce.rogers@gmail.com. We can exchange additional contact details through email if need be.

You need to press the play button in the top left corner. The data go as far back as last Friday. I will run an update to get new data at the end of this week again.

Yeah thanks, I am originally from Czech Rep. so I am more excited about hockey.

http://hamsterdb.com - a C++ key/value store. hamsterdb is AFAIK the only key/value store which supports typed keys (i.e. uint32, uint64, blobs). under the hood the btree optimizes the memory layout for this type, just like a column store DBMS does. I'm now moving slowly towards adding analytical functions, but it's still a long way to go.

A personal automated email sender, using vars and conditional statements (Eg. Multiple languages are possible, we live in a country where most of them speak: french, dutch, german or english, so that's a big + over here).

Create a poll (or mail) and mail them to clients when you sold for > 1000 € should be an option :)

It's actually meant to get feedback (automated) from clients with a more personal touch or to follow up on a sale of 1 month ago (how the car is, ...)

A simple CSS/JS library recreating the Windows 8 Modal. Still working on tablet/mobile support (which im pretty sure is just a css style cursor: pointer;)

http://ace-subido.github.io/windows8-metro-modal

Another side project I'm currently in the process of designing:

Personal Problem: Me and my wife have some folders with so many random files. Too troublesome and time consuming maintaining it to be clean and organized. Pictures should be in a specific folder, installers in another one, etc. an example is the "Downloads Folder"

Solution: A small command-line utility that organizes a folder on where it runs from. This small command-line tool has only one parameter: a JSON file that contains "Rules" on what it will do on specific files. ex: .mp3's should be placed on a folder, .docs on another, etc. And so on and so forth. It could also come as an "installable" service/daemon that watches over folders. Still learning more about Scala, it's used in where I work, may write this command-line tool in that language for educational purposes.

12y agoHN ↗

A simple script (in linux, windows or whatever) could do that no problem. In fact, I'm pretty sure something like:

find -iname ".txt" -exec mv -v {} /home/user \;

or

mv .mp3 /whatever/folder/youd/like mv .jpg /repeat/as/many/times/as/needed

would work. Is this what you had in mind? Hope I'm not way off base here.

EDIT: for some reason Hacker News edited out my asterisks and the letters within are displayed as italics. Curious.

12y agoHN ↗

Yep exactly! I know that it could be done via bash or a batch file. I just wanted to solve this usual problem with a simple project that also allows me to learn more about Scala since it's used at where I work.

12y agoHN ↗

Ah, I see! Well that's as good of a place to start as any. Good luck in your endeavours.

Docker replacement with emphasis on tool reusability. Docker made incremental builds right, and I love the idea. However, it reimplemented the whole tooling around it instead of using what's in there.

It will support FreeBSD/ZFS/Jails and Linux/LVM|BTRFS|ZFS/LXC on the first release. My goal is to re-use existing tooling as much as possible.

I am writing it in Haskell.

12y agoHN ↗

What I would like in something like that is the ability to push from outside an image to be used. Docker has push to a central location and then you need to pull from it which makes it harder for a small setup like mine.

Great idea ! Plus, your site does have good success as far as I can see! Appart from jQuery & bootstrap, what other technologies have you used to develop this site ?

Btw, is there a point system to reward people who predicts it right?

I'm working on a mobile/web app that lets users track their medication intake. It will use nfc tags that you tap each time you take the medication, so there's no risk of taking it more than the recommended number of times daily. It will also keep track of an side-effects you experience and prompt you to call the nearest pharmacy for refills. At the moment, I think I will target Android for the mobile app.

I found http://printaura.com via Google when we first decided to wire the generator up to a t-shirt print service, then I saw a http://shirts.io post on HN and wired them up too!

When each order is placed, we go with the printer that gives us the largest margin. There is no bidding going on or anything, they just have different prices for different products and calculate shipping fees differently.
