FTFY

That appears to be surprisingly uncommon. By that I mean maintaining the authorized keys file at all.

We didn't have DST in most of Indiana until about 10 years ago. When we switched, most of us were wondering why the hell we were even doing it. It's really not necessary, it confuses people, leads to screwed up schedules when the switch happens, and the fact that there are still a few counties that don't observe it screws things up even more.

While I agree that over-testing the wrong parts of your program can have an impact on program design, your end user's needs/desires are usually testable things. TDD helps make sure that experience is reproducible, even through sweeping changes to the codebase.

You'll definitely want to add a '&' at the end of that line so that you don't delay user logins if the network is down or mail barfs.

right, actually I do have a delay in a server with no mail where it fails :-)

I don't know that a Slack bot is the right type of larger solution though. For instance, I use the ExpenseIt app on my phone because it's paired with Concur. That's got a much more flexible input when it comes time to do the actual expense report, and it's already processed all of those receipts for me. Now I just need to go through and pair it all up with the transactions on the card. Is Concur perfect? No. But the ExpenseIt app works there because it allows me to add data on the fly then toss the receipt.

I don't think I would be compelled to use a Slack bot to do the same thing, even though we use dozens of other Slack integrations.

> The real value is in the presentation.

This is true sometimes, but if it's a design discussion and you're whiteboarding how something should be laid out, or even steps of what's completed and what's left, just a snapshot of the final state of the whiteboard is tremendously useful. It prevents the need for another person jotting down everything that was written up on the board.

And though it's not the presentation, its an aide de memoir of it (for those present).

Better than one's own jotting, in that the specific lettering and diagram shapes are linked to the presentation (though the cognitive processing involved in one's own jotting is also valuable).

A time-lapse would be great as well.

seems like the onenote revision history (undo, redo, and version tracking) could be hacked to accomplish something similar.

a video/audio scrubber control that lets you go back and forth.

also another interesting thing about OneNote is that it can record audio, and embed a time index of the audio into everything that is being written,drawn or typed into a notebook. Currently it highlights what was done at that time index of the audio. but it could be used to show the exact state of page at any given time in the recording.

The Audio recording feature has been in onenote since 2003 SP1.

So a GIF (or PNG) of the time lapse, as well as a still image of the final frame?

I was thinking of something with a slider so you can find that diagram someone drew in the middle of a discussion last week.

You should see what Imgur has done in merging GIFs and WEBM videos. Every GIF has full video controls, including a slider and a play/pause button.

So basically if we just hosted the timelapse on Imgur...

We've made a board that can achieve the playback. Made a quick demo video of our first prototype. Would love any more ideas! https://www.youtube.com/watch?v=uxmVtfF6pIo

Since the data on a whiteboard could be vector based, something like a diffed SVG could work better.

MS already has something like this in OneNote, but I'm not sure how frequent the snapshots are. It's more of a revision history than a "watch every letter be written", IIRC.

Where were your faulty detectors? My ex-girlfriend's dad used to do testing for a smoke alarm company a while ago. I learned an interesting thing from that. You know what they use to simulate smoke when they test smoke detectors? Hair spray. The fine mist is actually pretty good at tricking the sensor into thinking there are smoke particulates in the air. This also leads to an interesting failure scenario for many home smoke alarms: those close to bathrooms or in women's bedrooms tend to get gunked up with hairspray.

Hairspray is a bad idea IMO. It will leave residue behind. There are cans of fake smoke you can get at the hardware store. I worked on ships and tested smoke alarms that way.

Except my phone will get itself in a state where that latency stays high, and bandwidth drops for a long time. Only solution is to turn wifi off/on. That definitely seems like a bug.

I'm fine with lower throughput while discovery is going on, but when nothing's changed on the network I've been on for days, and my phone can't use wifi anymore, that's a bug.

Because it's still technically classified. When you hold a security clearance, you're not only agreeing to keep things classified, but also to not pursue any classified information you don't need to know.

This was a big issue when WikiLeaks started leaking info. There were regular memos circulated in DoD and DoE environments reminding people they weren't to be reading classified documents.

As is so often the case with government bureaucracy, that's pretty ridiculous (although I'm not disputing its truth). I can totally see it being a violation to knowingly look at documents that are clearly marked or otherwise denoted as something for which you don't have the need to know. But with something public that probably doesn't have classification markings, how can you possibly know?

Not just Google. Amazon's "Enhanced networking" uses a feature in 10GbE that's been used in smaller HPC clusters for around 5-10 years now. And MS Azure has InfiniBand backing their highest-tier instance types.

Many datacenters are adopting HPC technologies to reach the scale they need.
