I suppose this stops working if you SSH into some box and run tmux there? I've implemented something similar, but as an urxvt plugin instead, which avoids that limitation: http://www.cs.helsinki.fi/u/tmtynkky/urxvt.png (Once Alt-O is pressed, the hotkeys with the red background appear next to each link; pressing the hotkey opens the link in browser and copying to clipboard is also possible)

Would like HN feedback on a few areas (or course any area is fair game and I appreciate any and all feedback):

+ Performance, responsiveness

+ Usability, UX

+ Use cases

Tivia is Titanium-based so I am particularly interested in HN opinions on the first two items, especially as compared to similar native apps. Thoughts?

The Tivia alpha is an MVP - it is too broad right now - basically the plumbing. However, next is extending into use cases that are important to community groups. Ideally, replacing their website, mass email distributions and mass text messages. Thoughts?

Finally, please be as harsh as you wish, that is exactly the feedback I need, but known shortcomings that will probably be repetitive:

+ Security/encryption (WIP)

+ Address book filter/search (WIP)

+ Media zoom

Dashing is prevalent throughout my company (we have them on TV's throughout the office), so if you monetize toward that angle, perhaps as an already baked widget that would definitely be appealing as well.

No. Watch is typically used as a piece of jewellery, so it should look like one. I'm yet to see a good-looking smartwatch.

Moreover, idea of a watch that needs to be recharged every two days is ridiculous. A quartz watch can go for months on a single battery.

And in exchange for frequent recharges one basically gets nothing that couldn't be done with a smartphone. It's not like smartwatch allows playing with software-defined radio, which is the case for Texas Instruments.

It's all about how you look at the problem. I bet you can easily divide 100 by 25 and multiply by 3.
I can't help but look at the roads and sidewalks and think there's a solution that could be implemented there. I'm no engineer, but I expect that you could install something along the fault line that allows the road to slide apart without disruption. It seems like a waste to just keep repaving the same spot over and over, just for it to crack again.

Maybe tear up a couple feet of pavement and put in two metal grates that can slide past each other. That should at least buy you a decent amount of time, until the road is so warped that the lanes don't line up.
Just wanted to add onto this with some information I've gleaned lately. My business consultant takes me through a lot of different ways of looking at personalities and right now we're on Jung.

A lot of INTJs hang out here; here are some common INTJ mental tricks:

* Holding yourself to a higher standard than those around you

* Expecting yourself to make extremely bold, large career moves

* Holding yourself to a tighter timeline than you hold others

* Expecting yourself to achieve things on an unrealistic timeline

As INTJs mature (i.e. through and past midlife), it is common for them:

* To learn to make the small, bite-size steps that can help them put their big-picture plans into action

* To learn to be easier on themselves

An INTJ in the grip of their inferior function (stress, illness, tiredness / exhaustion) will commonly:

* Binge on things that indulge their senses (from TV to loud music to porn to food to exercise)

* Get zero enjoyment out of the binging

* Take an adversarial attitude toward the outer world (so-and-so is plotting against me, etc.)

An INTJ can escape this by:

* Using their gift for thinking to plan, learn, write, chart, and strategize about ways to escape their unrealistic expectations, currently sub-optimal situation, etc.

* Remembering that what others think about you is often a result of that person's personality dynamics, rather than whatever you, (the INTJ) think the other person must be thinking about you. For example, if you think an ENFP may be plotting against you because of something he said, that probably says more about your stress levels than it does about the ENFP's disposition.

A good reference (and not just for INTJs): "Beside Ourselves," by Quenk.

I hope this can be helpful to someone. It helps me just about every day.
Jacking and lifting of houses are typically done when it's a relatively "static" issue that was improperly addressed when first built. For example, certain soils (mainly clays, very fine grained soils) compress and undergo consolidation (i.e. compress downwards) as a function of weight and time. Consolidation, when expected, can be mitigated and/or accelerated to "get it all out" so that there is no differential settlement in the future. For example, this here [1], looks to me like a case of differential settlement that resulted from improper excavation and back filling during original construction. In the case of fault-lines and stochastic motions? It's a lot harder to say what can or should be done in a general sense. Luckily the frames of most houses are made of wood, which has more forgiving properties (failing more with more ductility) than masonry. Unfortunately, the exterior shell of some houses are brick, which won't be so forgiving as the wood that it surrounds.

There are used in drug interdiction and other coast guard functions. My brother was an Air Force test pilot that tested these for that purpose (he was originally a surveillance pilot flying kc-135s). They are basically a kc-135 in a small jet (e.g., leer jet 35) form factor, and not carrying a team of technicians in the back but instead just equipment, or maybe a technician or two. Officially he's not supposed to know.
I'm fully aware that octane isn't energy density - octane is a long chain which prevents pre-ignition - hence pinkpinkpink - pre-ignition - pinking. I had to fill up a mercedes 190E 2.6 on 60 on one occasion, and fuck did it hate it - particularly as I'd lost my exhaust somewhere in the desert. Set off car alarms when I got into town, just by driving by.

My point was rather that they require fuels with such incredibly low octane ratings due to the astonishingly crap compression ratios on ladas, volgas, and yaz trucks, and most soviet technology. The point was that they could run on near-as-damnit bunker oil, watered down with expensive petrol.

Because these vehicles are still in use, they produce an extraordinary amount of pollution, as the low temperature burning that occurs in them results in a crap-tonne of soot.

Same kinda deal with diesels, but again, their diesels will literally run on bunker oil, and you wouldn't believe the incredible clouds of crap that spew forth from them - particularly when they have no exhaust system.
Thing is, with lightning it is dead easy because you're talking about what is essentially a straight line through the atmosphere.

It's because the engineering school is destroyed in America (and elsewhere too).
Can you even get a 10-20mpg car without resorting to niche items like heavy trucks and such, where the buy would be fairly sophisticated in fuel usage considering its pretty much a work truck? This probably isn't too big of a concern from a practical standpoint. Avg fuel economy in the USA in 2014 is 24.1. Changes from there are small increments, ignoring hybrids and ultra-efficient vehicles.

True. However we know shockingly little of how neurons actually do computation. Everything a neuron does it does so with a combination of electrical and chemical signals. This is why it's slow, but it also introduces considerable noise in the process.

Also, because they're usually in some skull-like object, and because neurons are incredibly hard to culture, we simply lack the tools to observe them in their natural environment to the resolution you might want. Simple questions like how often a neural signal fails to cross a synapse in a brain are remarkable difficult to answer. Do we need to know how every neuron is connected to every other neuron in the brain to understand it? Even if we had such a map, would it be missing something so crucial as to be useless (for example how glia interact with the neuron)? Nobody can say for sure right now.

I think you hatin on the company is unwarranted. Millions of people already trade stock. Given that they do, they are better off paying less for it than more. Investors who trade infrequently and trade something like SPY also benefit because they get lower fees and, hopefully, they don't need brick and mortar support. "Whales will always take their money elsewhere" - why ? Why do "whales" want to pay more for their trades. I am not saying Robinhood is the second coming of Jesus, but I don't see any good reason for hatin' on the company, the way you do

Spend 5 mins on the road in Missouri and you'll see 100 new cars go by with a scant trace of engine noise, and 1 1994 geo metro missing an exhaust, plastic wrap over one window, two doors of different colors, with the driver on a cell phone smoking a pack of Pall Malls, riding on 3 bald tires and a spare, with the rusted tail pipe spewing white smoke. They pull into quick trip and run inside for a bottle of oil so they can fill up the engine before they pump their gas.

Once again, liberal regulations new cars hardly solves any problems, but looks great for pleasing the voters of "blue states." ...sort of like providing tax credits for new home owners for energy efficient homes... Where apartment complexes have air conditioners from 1970 and the tenants pay the electric bills. All these regulations just add cost to doing business without providing any real benefit to the environment. But the regulations buy votes, so why not?

If we want this changed, we really have to start voting for science, which currently, neither party can associate with. Stupid stupid stupid.

What to Do in 12 Hours in Whistler
As far as whacky comparisons go, I'd always wanted to do some back of the envelope calculation comparing smokers' CO2 output to cars'. Also, always wonder how much cigarette filters (that are supposed to capture various chemicals) that get thrown on the floor could contribute to (e.g.) water pollution, if at all.
Ah yes I remember this! I was always bad at typing out the numbers though. We support range selection as well, but it does require a keypress for each (which is less than ideal if you have a ton of entries).

Redwood City, CA had the first system. It was much simpler than this. They had analog microphones on phone poles, connected to a logarithmic amplifier which traded dynamic range for bandwidth. Phone audio is 8 bits at 8KHz; think of this as remapping to 16 bits at 4Khz, although it was done with analog hardware. They needed the dynamic range to see the full risetime of a gunshot, and gave up a big chunk of the voice spectrum to get it.

Each microphone had a wired phone line connection to the central system at the police station, which was a PC with a data collection card running LabView. A LabView program turned gunshot information into map plots. It was a simple, local system.

The new systems are much fancier. They're "cloud-based", which means the data goes first to ShotSpotter's HQ. They have synchronized clocks (probably from GPS), so they can send in timed audio snippets to be matched at the analysis center. It's a service now, rather than just hardware. Not clear what kind of data connection they have; probably cellular data.

Relentless self-promotion?

Oh, community college.
With regards to your concern, it's important for any leader to know their own weaknesses. Given that you know you're not a superstar developer so if you'll be hiring one as part of the technical team, make sure you pay attention to what he/she says. Listening to others will help you gain respect. The CTO's role will be enable the technology to fuel the business. It doesn't necessarily mean that you have to be the best developer but it means that you have to help your technical team to achieve it. Give them the tools, ask for their expertise, let them make it happen and communicate the business strategy to them.

At such an early stage, you'll probably need someone who is a self-starter who can play multiple roles rather than someone you will have to "manage". However, given that you don't have a solid technical background, it will be tough to make a lot of decisions without consulting your technical team. Find someone who is a technical expert but is also willing to help you, not overtake you.

They mention gigapixel cameras, my (brief) googling couldn't find any evidence that such a thing exists, except for an experimental one at Duke https://www.youtube.com/watch?v=ldQXHP7TFUE. Although I suppose a gigapixel photo can be made by taking pictures by multiple cameras at the same time just as well. Still, wouldn't that sort of thing be available commercially, at least for the enthusiasts out there?
I am blessed and I do know it. I never said that other careers are more or less "trapping" than mine - I know that for the most part they are not.
My advice to others is the same as yours - quit now and try working in another profession. But it is not to see if their definition of "trapped" will change, but to find out, before it is too late, if there is something they find more rewarding.
I always interpreted my colleagues "trap" statement from long ago not to be about software being career/financially limiting but about satisfaction limiting. Am I coming/rationalizing when I say "I love my work"? I don't know.

The problem is the proximity of humans to cars. The results are form a study done at UofT Eng Dept. The crux of their findings were that it takes much longer than anticipated for the levels of 'pollution', in various form, to drop in concentration with distance from the source. I think the following excerpt from the UofT press release is the most intriguing[1];

“The ultrafine particles are particularly troubling,” says Evans. “Because they are over 1000 times smaller than the width of a human hair, they have a greater ability to penetrate deeper within the lung and travel in the body.”

On a typical summer day in Toronto, Evans’ instruments measure approximately 20,000 ultrafine particles in each cubic centimetre of air. This means that for every average breath, Torontonians are inhaling 10 million of these nano-sized particles. These numbers increases to 30,000 and 15 million in the winter, when there is more stagnant air and less evaporation of the compounds."

I have also spent long tenures at a company or two, and also took continuous self improvement seriously. And yet I can think of plenty of people I knew 15 years ago who are focusing on the same kinds of problems and technologies today that they were back then, who have fallen victim to the sweet lullaby of the comfort zone.
Or any form of wide-area surveillance, which isn't necessarily the same as surveillance of mass amounts of people. From an article I read yesterday, the first documented use of FBI domestic surveillance planes was a bribery case that involved a payoff package tossed out of a train in the 30s.

So, these things do have other uses.
The difference is that a general purpose database typically organises data by fixed-size pages, so new data could be anywhere in the file as there is no guarantee of page ordering with regard to inserts. Whereas a specialised file format for logging would add new records at the end of the file (or in a circular fashion, depending on the design). But will have features similar to a database like a defined schema, and some form of indexing. This is true of systemd journals and Windows event logs anyway.
That's a good point, though I don't think it's such an uncommon thing; think of the beginning programmer who has to be laboriously convinced that the first definition they learned for "type" or "function" is not the meaning of that word.

I'd speculate that true appreciation for jargon comes more from multidisciplinary studies than anything else, so in any field the most passionate, least experienced members are likely to make a mess of things-- and if there's one thing the activist community has in surplus it's members with a high passion:experience ratio.

Having acknowledged that issue, I'm still reluctant to excuse anyone in this case, simply because we're talking about a term that doesn't have any other meaning. If you see a word you've never heard before, and think "I can probably figure out what this refers to based on its sounds" with Google sitting right there, naah, the problem isn't the jargon.

Edit: Like, seriously, would this happen if the word was "microclimate" or "microevolution"? Yeah, on the YouTube comments, but not usually on HN.
