jsonau··on Djinn Split Keyboard
Are you referring to controlling the mouse cursor? If so, it's possible with "Mouse control" in Oryx.

I have a layer(Media 4) that is activated when holding a specific key on my default layer so I can control my cursor: https://configure.zsa.io/moonlander/layouts/bdYBP/latest/0

jsonau··on Ask HN: The most useful Mac keyboard shortcuts?
Command+? (Command+Shift+/)

Brings up the Help Viewer where you can search any menu items for the current app.

This IS pretty much the built-in command palette for all apps!

jsonau··on Password expiration is dead, long live passwords
Another worst offender are security questions to unlock accounts. Answers to these questions are usually visible to customer service reps and similar set of questions are asked among different services. This is scary.

It's dangerous as having password stored in plain text as answers to the security questions can potentially unlock many other accounts.

I highly suggest everyone answers each of them with a unique answer.

jsonau··on Show HN: Mochi – Make notes with markdown, study them with spaced repetition
Kudos on the homepage "screenshot" -- It's actually the app itself.

Love the app!

jsonau··on Ask HN: What are your favorite utility desktop apps?
OSX:

Dash - Snippet Manager and API Doc Browser https://kapeli.com/dash

Flycut - Clipboard Manager https://itunes.apple.com/us/app/flycut-clipboard-manager/id4...

Spectacle - Window sizing Manager https://www.spectacleapp.com/

jsonau··on Show HN: Kite, copilot for programmers, available for Python
Yea was annoying. To prevent them from resurrecting, remove kite processes managed by launchd before killing the current processes

* launchctl list | egrep kite

* launchctl remove :KITE_LABELS

jsonau··on Generals.io – Capture enemy generals to defeat them
I'm definitely willing to pay $1 for a dedicated lag-less "channel"
jsonau··on Bitcoin Beat the Trough of Sorrow
What you said is true. Banks can always lower their transaction costs as they see fit(competitions) and beat BTC transaction fee anytime. So transaction cost might not be an advantage in such situation.

But people might still use BTC and pay up that extra cost because of its special property: true ownership.

jsonau··on Ask HN: How to tell if a home is unoccupied?
Cheapest method: Assume the government really want this number, they can have all mailman help keep track if there are leftover mail(a letter is created/given if resident has no mail) after x days.

Technology wise, I cannot think of an easy and cheap way. Camera with vision for each residential door will be a robust approach. Accuracy can be precise by more investment in software from detecting opening-of-door-event to facial recognition of the expected household members.

jsonau··on Ask HN: What are you reading this weekend?
Hitchhiker's Guide to the Galaxy
jsonau··on Herman Miller Launches New Aeron Chair
Yea your assumption is right. What's worst is I have to put a tshirt on my back so my sweat won't transfer to the fabric-back.
jsonau··on Rant HN: I hate hackerrank
@OP: You sound almost exactly like me. I have not done any interviews for a bit more than 5 years. I think the what really can be improved is to test us in a more familiar and friendly environment. I have to spend time on handling time-pressure, and fix/adapt with my thinking habits.

## Coding Problems:

I do think coding challenges(algorithmic) has merits, but I think there are two factor that really hinders a interviewee's performances:

- time limit

- require an unfamiliar algorithm

Time limit is obviously needed in a test, but problem solving in real life is never instant unless it's done before. Nevertheless everyone have their own pace. I have to dedicate hours each day to train myself to adjust my brain to act quicker yet calm for these algorithmic questions. Sometimes my initial solution in my mind turns out to be the best, but I discard it. Nevertheless if one is stuck, the time limit just makes it worst. I'm also known to be the slowest in turn-based board game -- I have high win rates though!

## Possible Solution?

* Allow interviewee pick from a pool of equally-difficult-challenges to solve (within a minute or two). This can solves the "obscure algorithm" or "trick" question. This also helps the time-limit problem as the interviewee WILL interpret the question twice in two different VIBES (with and without time pressure)

Even choosing 1 out of 2 would dramatically reduce nervousness and time pressure.

jsonau··on Tell HN: MacOS turns off the fans when Siri is listening
Would noise cancelling(ANC) help in this case, even if the mic and fan are near each other?
jsonau··on Ask HN: Interview tomorrow – How to learn whether an org is “healthy”?
Or they're being transparent with good intentions?
jsonau··on Pokémon GO: The Data Behind America’s Latest Obsession
Everyone now with a smartphone can Pokémon game for free! This captures the previous market who grew out of it. Furthermore AR works very well with the Pokémon theme.
jsonau··on Show HN: Teevox – Twitch Multistream Player,made in Static HTML, React, Firebase
The other 2 stream might be boring at the moment(streamer afk, in a game queue, etc)
jsonau··on Half a year later, the Apple Watch feels like a stalled platform
Yea I'm really surprised Apple didn't go with this route initially. Add the heartbeat measurer + calories burner and it will be the perfect fitness assist device.

I guess they don't want to pigeonhole a device into a specific category.

jsonau··on Perl secret operators and constants
I used !! in many languages including Perl. Not exactly secret and very useful
jsonau··on Google Tone
I can see meetings and presentations using this very well. You can broadcast a link locally with a push of a button -- no need to know anyone's email or screen name. Listener don't even need to know the URL itself. This makes UX near seamless!

Imagine giving a presentation in a public conference, you can provide resource (per x slide) to all of your listeners(strangers and what not) for referencing without ever saying anything about it.

jsonau··on Show HN: Sssaving – Are you gaining or losing money each month?
Intriguing font choice and design! I like it. Unfortunately I'm hesitant on giving my bank credentials.

Big banks should step up and offer APIs via OAuth or the likes

jsonau··on SpaceX Profitable as Musk Pulls in NASA Contracts, Google Cash
Assume self-driving car is perfected, Google can easily offer better mobile/local ads for both business and consumer because of context.

Show popups ads of ongoing/upcoming events of the current street you are on. Going to the movie theatre, recommend a nearby lunch spot. Feeling lucky? Let the car plan your weekend

This bring huge potential to ads

jsonau··on CMU Accidentally Sends Out 800 Acceptance Letters To CS Program
I will put money that they use the incorrect email template (acceptance vs reject)
jsonau··on Why Warren Buffett Just Bought Duracell
A bit off topic. Looks like Duracell has a cloud storage service, which is really strange.. https://www.duracellcloud.com/
jsonau··on Show HN: Hack Your Mortgage
The interview UX is well done. Definitely didn't feel intimidated or bored answering those questions.
jsonau··on Show HN: Automated Discounts on Amazon
Based on their FAQ, they act as a proxy, in which you pay them to order goods from Amazon. And you will use this proxy because they will do the heavy work of finding the lowest price for you.

If anything, Amazon will punish Zinc rather than the receiver of the goods.

jsonau··on hr for your terminal
should rename it to hrd
jsonau··on Ask HN: How much recurring income do you generate, and from what?
Haha good job! Interesting niche and decent site!
jsonau··on Apple’s iPhone 5s And iPhone 5c Sell 9M Units Over Opening Weekend
Assuming you dont voice much. T-Mobile offers prepaid(bring your own phone) $30/mo unlimited 4G and SMS with 100 minutes. Assuming you always want the latest iPhone, you save about $200 per 2 year. This deal was way back before LTE availability, So it WAS a hot deal.
jsonau··on SSL Report: duckduckgo.com
Cool tool.
