bittersweet··on Mouseless – fast mouse control with the keyboard
In your video you mention not being able to use tab, enter etc for system dialogs on Mac, if you enable 'Use keyboard navigation to move focus between controls' in the Keyboard settings (under Shortcuts), you can cycle the focus with tab (and shift+tab), and select them with space. It's one of the first things I enable on a new install :-)
bittersweet··on Show HN: I am building a Safari Web Extension to switch tabs efficiently
This is a great idea! I have been using Vimium [1] for years now in both Chrome and FF which provides similar functionality, it's a real productivity booster for me.

Vimium calls their flavor the "vomnibar", and you can search in open tabs, history and bookmarks. The bar is my most used feature next to navigating on pages, opening links and managing tabs (Go to previous tab, pinning, muting, closing, duplicating). It might be a nice extension to take a look at for even more inspiration!

For people wanting tab switching like this on Chrome or FF, I'd say give Vimium a shot. Even if you're not into Vim-like key bindings, knowing Vim is definitely not a requirement to getting value out of it. It allows me to be completely keyboard driven.

Vimium provides go-to-previous-tab via `^`.
bittersweet··on Dutch Cities Ban 15-Minute Delivery Services
The article mentions the nuisance caused by darkstores, but does not go in depth. I've recently came across a small instagram [0] that details some of these. I want to mention some of the nuisances.

Especially in Amsterdam the infrastructure in neighbourhoods is not suitable, the stores need to re-up their supply many times a day (10-15 times), leading to (bike) traffic build up in the often narrow streets [1][2].

They also supply in the weekend, which goes against local ruling on when business can load/offload (generally not in the weekend).

Their scooters and bikes take up a lot of space on sidewalks as well, which normally was used by residents only.

bittersweet··on Warez: The Infrastructure and Aesthetics of Piracy
You might be remembering pftp, which had a few modded versions (mew6, "shit").

bittersweet··on Show HN: I've been writing daily TILs for a year
I love this! I started doing this years ago as well via a simple notes dir in my dotfiles (example [1]), and actually wrote a small tool to help me with it [2]. This way I can list all the note files I have (cli, zsh, vim etc) and pretty print them a bit and have search if I can't remember the exact thing :)

bittersweet··on GoPro cutting 7 percent of its workforce
People have mentioned the Garmin Virb being able to do this, and I have to mention that their software [1] is great and easily useable with any video file. I've used it to sync up my bike rides recorded with a Go Pro to my .gpx file and show speed, map etc. You just have to manually sync the start of the file with a start point in the video, which is easy enough.

The GoPro software is horrendous in comparison as I could not even import my video files (one of 4,5 gb and another one of around 1,5) with over 25gb free space. Maybe it needed to convert before importing? In any case I just joined up the files with ffmpeg and imported in Virb and off I went, very recommended!

bittersweet··on Show HN: Golongpoll – Go HTTP longpolling library
I've been using SSE with Go for personal projects, so just one browser, could you expand on the issues you mentioned? I'm curious if it is indeed as bad as you say.
bittersweet··on Running three hours of Ruby tests in under three minutes
Seconded, I have not thought about this before or come across this idea at all and certainly sounds interesting!
bittersweet··on Ask HN: Open source OCR library?
I was actually looking in to Tesseract yesterday, so this post coincides nicely.

I have a hobby project where I scrape instagram photos, and I actually only want to end up with photos with actual people in them. There are a lot of images being posted with motivational texts etc that I want to automatically filter out.

So far I've already built a binary that scans images and spits out the dominant color percentage, if 1 color is over a certain percentage (so black background white text for example), I can be pretty sure it's not something I want to keep.

I've also tried OpenCV with facial recognition but I had a lot of false positives with faces being recognized in text and random looking objects, and I've tried out 4 of the haarcascades, all with different, but not 'perfect' end results.

OCR was my next step to check out, maybe I can combine all the steps to get something nice. I was getting weird texts back from images with no text, so the pre-processing hints in this thread are gold and I can't wait to check those out.

This thread is giving me so much ideas and actual names of algorithms to check out, I love it. But I would really appreciate it if anyone else has more thoughts about how to filter out images that do not contain people :-)

bittersweet··on Rubygems.org compromised
Qrush, one of the guys behind Rubygems tweeted that the credentials of every yml file ended up on pastie: https://twitter.com/qrush/status/296638346283868160

> Someone posted http://rubygems.org 's config/*.yml to pastie. Didn't include the S3 bucket secret key, but going to reset everything anyway.

bittersweet··on Bash One-Liners Explained, Part V: Navigating around
The author notes that there is no meta key anymore [1], however you can often setup your terminal emulator to use another key as the meta key.

In iTerm [2] I have the left alt/option key setup as meta, so things like meta-b are much easier to type then Esc-b.

[1] "You'll often see Meta+b but there is no such key on the keyboards anymore." [2] Profiles -> Keys "Left option acts as meta"

bittersweet··on Goldeneye 64's inspirational startup story
This article seemed very familiar, and I found the original article where a lot of the quotes/text came from, 'The Making of Goldeneye' from may 2011 [1]

bittersweet··on Show HN: Receive desktop notifications from your web apps
And are you poling the noti server? I'm wondering how realtime it is :-)
bittersweet··on Show HN: Receive desktop notifications from your web apps
Interesting, could you shed some light on the tech behind this? For example, does this use a custom solution to display notifications or Growl / ML notifications?
bittersweet··on Raspberry Pi runs XBMC; reliably decodes 1080p (January)
It does have some problems with decoding DTS content (I don't have a receiver) though. I've tried a couple of things already like overclocks and re encoding the audio but I'm still trying to find the sweet spot. This is all on RC5 raspbmc, still have to try openelec.

bittersweet··on Rails 3.2 feature: unreadable production logs
Tim Pope has written about the model commit message [1] and why you should use a short first line, I'm a big believer in this setup and it's done wonders for the readability of my commit messages.

Github itself even uses these rules [2] so I think it's slightly annoying people don't follow them as it looks worse if you use long first lines on the website.

bittersweet··on Hacker homes: Would you couchsurf Kansas City just to get Google Fiber?
I've recently gotten a 500/500 fiber connection (I'm located in the Netherlands) and it's been fun, but I haven't found a way/service to saturate it yet. It's fast enough that I don't think about the speed but 100/100 would probably be able to provide that as well.

An internal network with just fiber subscribers would be cool though, I seem to remember old DirectConnect networks that would only allow university connections with big links.

Not completely what you are looking for, but I found a Chris Granger inspired vim theme: https://github.com/chmllr/vim-colorscheme-elrodeo
bittersweet··on Mandrill - Transactional Email from MailChimp
Are you guys using anything in particular to power the webhooks?

I'll be integrating webhooks in my own app soon so I'm quite interested how others have 'solved' that so to speak.

bittersweet··on Mandrill - Transactional Email from MailChimp
Seems you can set up webhooks to do just that! [1]

These are the events: send, hard_bounce, soft_bounce, open, click, spam, unsub, reject

bittersweet··on Show HN: YourPictureGetsMine.com
You could take a look at face.com for a face recognition API. Have only used it for some demo apps and it worked alright.
bittersweet··on Git-sweep: a tool to remove your merged feature branches
The fun thing is, because you named it git-sweep, you can use it like a regular git command instead of needing to use git-sweep, for example: git sweep preview
bittersweet··on TylerWM - a tiling window manager for OSX
This looks great but after browsing their twitter feed [1] I can see that they have troubles getting updates approved in the app store because of the sandboxing.

bittersweet··on Stealing Your Address Book
I did this as well, it seems very obvious but it's a great insight in human behaviour.
bittersweet··on Google App Engine Mini Profiler
Just like the author of this blog post I was inspired by the MVC mini profiler and started a Ruby gem that has some very very basic functionality at the moment, you can find it here: http://github.com/bittersweet/stopwatch

It just shows the page load duration and amount of queries so far but I plan to have the same functionality as the original and GAE one :-)
