Thanks for your interest in our work! (Lead author on the ultrafine particle mapping paper).

The SOCAAR facility has operated at this roadside location since 2006 and is one of the largest air quality research lab in Canada.

Over the years, we have routinely seen peaks in CO2 as vehicles pass our monitoring station. However, when some vehicles pass, we also see NOx, black carbon or ultrafine particle peak(s).

While we have video footage of the road, it can be extremely difficult to link the measurements to a single passing vehicle. Identifying these vehicles and why their emissions are different from the rest of the vehicle fleet is where the research our heading.
I programmed in my spare time because I was curious. After a few months I started building little applications to make my life easier. My co-founder and I then had an idea and we wanted to bring it to market. I continued teaching myself until we got to our beta complete.

I figured we're a two person startup and I'm writing code and building the beta, I guess that makes me the CTO?

You seem to be suggesting that using local i/o to read inputs would be preferable to using remote i/o, but I don't think that's a supportable statement in a datacenter with a high-performance network.
And insanely, they're interested in "detecting gunshots" rather than stopping them in the first place, by, you know, taking guns away.

I'm not from the US, so it was quite shocking to be a friends BBQ outside LA and hear multiple gunshots over the course of the night. They are quiet teachers, and have kids. They don't need gunshots in their lives.
Literally any photo you see will be 'impure'; as soon as the image is captured from the sensor, the raw data goes through many, many transformations before it arrives at the final image (white balance, exposure adjustment etc. etc.). I guess we could draw the line at how much post-processing is applied. Having said that, photography is very much an art form, and post-processing is just one of the many steps which goes into creating the intended image.

Film photography also has many variables such as film type and development process - fascinating stuff!

Function call overhead in cgo is considerable. You're right that it's not from copying, but the runtime scheduler still has to coordinate the blocking call, and the stack needs to be switched out to the C stack, kind of like a context switch.
" Among the companies offering this technology are major defense contractors working for the Pentagon and an Ohio company called Persistent Surveillance Systems, which is trying to sell it to local police departments."

I know this is an unpopular opinion these days but the people working for these companies should be ashamed. There is little use for this technology, especially on US soil, except mass surveillance of the population.
Yep, that's still going on. I've received a couple of letters offering to buy my 1993 Toyota MR2. The letters do say something like "If your vehicle is a classic or is otherwise special to you, ignore this letter." It is a bit of a classic -- in any case, it's worth a lot more than the $500 (or $1000? not sure) they're offering.

With 92 shooting victims in that same time period, I'm guessing that's a massive undercount. Probably only counts times they catch and charge a shooter.
Through some rough lessons I no longer take on many projects that I am personally developing outside of a day job. In general, I bill $x per person:block:day (being each day that I work on something 0-4 hours, and each additional block capped at 4 hours)... Anything that is not a core part of the product (business logic, or specific design elements) may be abstracted away, reused and/or released as open-source. I will also use, as appropriate already written open-source code that won't elevate the risk of said project (no agpl, only gpl if it's a server-side solution). Once a solution is finished and paid in full, any copyright over the solution will be signed over, and will not include outside libraries, even those written to help with said project. I emphatically do not believe in Patents on software, so will not apply for or assign any such rights on what I develop.

For the most part when you talk to a client openly about how software is assembled and crafted, and that their part of the product will be theirs, and that you will deliver a finished product while also respecting the larger development community in contributing back, it's usually a smooth process. These days we, as software developers, tend to use large amounts of mit/gpl/isc/apache and other openly licensed software/libraries, that when you explain that what's out there saves you time, and giving back saves everyone time, it's usually less friction.

I also expressly do not bid on entire solutions that are not well defined, or are too strictly defined. It tends to become a time sink if you do. And prefer to bill in blocks/day against a deposit against the estimated work/time. I also make clear that what I give is only an estimate, and actual billed blocks may vary depending on changes through the lifecycle of initial development.

----

As far as a day job... I tend to line-out anything that can be construed as assigning rights of work I do outside of the office on my own time, or Patent assignment. As a rule, I only interact with hardware through defined software interfaces. If I were building/designing custom hardware to accompany the software I might have a different stance.

----

If you are uncertain, or unsure of how to establish a written contract, as always you should contact a lawyer.

A lot of people hate having bluetooth enabled because it enables another potential tracking vector.
No problem.

Yes, that might appeal to law enforcement, even if their intentions are good. It would be interesting to compare the benefits to other programs, like raising the amount of patroling police etc.

I happened to start working with a similar system today. For our customer there are several factors they are interested in:

# Mapping gunshots in both time and space. These types of sensors can attempt to classify the type of weapon used based on the audio signature. If there are are several shots from similar-sounding sources moving through the city at a certain, or in a certain area over the period of days (or month), this can tell you more than you could determine from just emergency calls.

# Tieing the gunshot sensors in with other input devices, like cameras. You can reduce the time spent looking through, say, traffic camera recordings that happened in the vicinity of the gunshot looking for related video.

# Automatically pointing moveable cameras to look in the direction of a gunshot. Means you don't need as many camera for the same effective coverage.
This isn't really true as the Windows event logs contain text as well as the other structured data, which you can search for using tools on the system. For example to search for some specific text in the system log using Powershell:

Get-EventLog -LogName System | Where {$_.Message -Match "something"}

To process text as fields, as with awk, one would use the Split method (at least to start off with):

Get-EventLog -Log System | Where {$_.Message -Match "something"} | %{ $_.Message.Split()[5,4] }

But as message text is often parameterised, it may be easier to take advantage of this data to get what you need. For instance, this command would extract the latest machine sleep and wake times from the system log, and calculate the duration:

Get-EventLog -Log System -Source Microsoft-Windows-Power-Troubleshooter -InstanceID 1 | Select-Object @{n="SleepTime";e={$_.ReplacementStrings[0]}}, @{n="WakeTime";e={$_.ReplacementStrings[1]}}, @{n="SleepDuration";e={([DateTime]$_.ReplacementStrings[1])-([DateTime]$_.ReplacementStrings[0])}}

One can also sort and get unique values, just as in Unix-type systems - this command lists all drives defragmented in the past 30 days:

Get-EventLog -Log Application -Source Microsoft-Windows-Defrag -InstanceID 258 -After (Get-Date).AddDays(-30) | Select @{n="Drive";e={$_.ReplacementStrings[1]}} | Sort Drive | Unique -AsString

So all the same capabilities are there, and then some. You just need to know your tools well enough to take advantage of it.

As framed/contrasted in the article, the term "learned helplessness" seems a bit off. If we look at the venn-diagram, it would appear that we have: things we care about, things we can change, and things we don't realize we can change. It's those things, that are "learned helplessness" -- and a way to avoid it is to form "informed helplessness": to have an accurate idea of our world: what we really care about, what we can really change and what we really cannot change.

First find out what we actually care about. Then figure out which of those things we are unhappy with. Then which of those we cannot change. This is our area of "informed helplessness". Periodically re-examine this area, to check if some things have become more malleable by ourself (this is to avoid "learned helplessness", or "artificial helplessness".

The point being: if you sit down and figure out "what you cannot change" -- you're effectively teaching yourself to be "helpless" about those things. The key difference is presumably that it is a rational, active, decision.

Perhaps the literature/research have some better terms for this -- but I felt it looked a bit inconsistent in the article.
I'm pretty sure pinging services and such were out of their ToS anyway. They're better facilitating non-sketchy free users by giving them the Scheduler and a worker, and have given people who absolutely need 24/7 service a great service for dirt cheap.

I bet most people who need the 24/7 service probably have the money to spare, and I bet most people are overestimating the uptime they need anyway.

On the flip side, for a small flat fee, I can now have 10 processes running on a 24/hr server, effortlessly. I'll pay the 7 bucks for an easy deploy. Most of my projects are going to be hosted on Github Pages or Heroku's free tier anyway.
Yeah, well, trying to "[take] guns away" would trigger a civil war that would kill orders of magnitudes more people. That, in fact, is what sparked the American Revolution, when the British attempted to seize or destroy gunpowder, cannon, etc. (they did manage to damage 3 cannon).

If those people don't need gunshots in their lives, they should move to some place where they're not so common. Like the majority of the US where concealed carry is legal and, it is my impression, such bad areas are much more compressed.

How about cryptogenic stroke?http://www.ncbi.nlm.nih.gov/pubmed/23366107

I think it's relatively clear that the tech works in a controlled setting. It even works surprisingly well in an uncontrolled setting. But as these devices become more mass marketed, sensitivity and selectivity become a much bigger concern. If you detect 99% of all true events, that looks great at first. But how useful is it if only 10% of all detected events are true? Selectivity must be tight before we can issue strong health warnings to masses of people. The challenge of real world noise can be bigger than getting the first principle tech to work.

It's a limited-purpose trust company - it can only accept assets as trustee and cannot hold cash as a customer deposit. Because depositors' funds aren't at risk, these entities don't have to join the FDIC and are exempt from some other regulations.

I guess because itBit acts as a custodian for Bitcoins and not just a transmitter, the DFS thought it was a closer fit than a money transmitter license.

There's also solar electric propulsion, which when combined with water as propellant, leads to dramatic (10-100x) cost reductions due to increased propellant efficiency plus the synergies created by using water as reaction mass (it can be used for everything from radiation shielding to crew consumables prior to being sent to the engines, which effectively turns most of your consumables mass into propellant).

This approach also benefits from ongoing improvements in component technologies (thin film PV, electric propulsion, and inflatable structures), so a reusable spacecraft based on this design pattern could be upgraded as things improve.

> this thing is a solution to a very tiny problem: gunshots that are not reported via emergency calls

I wondered how big a problem this is, but the only number I quickly could find is annoyingly from their advertising material and claims that in some areas only 10 % of shots were reported, which is not really the relevant number. Does anyone have a number on how many people die of gunshot injuries that either weren't reported or reported to late?
Yes! Probably my biggest workflow pipe dream since getting some fluency in vim is to be able to drop into an "outside mode". I've cobbled something vaguely modal together for bspwm with abuse of shkd, so a lot of the binds map similarly, but like your solution it's far from ideal.

As for "Why would you want this?" For me, the straightforward answer is "modes are modular". A core concept in vim is that your input can be thought of as a string describing the edit you wish to make, and modes help me keep that manageable in my head: I can first think about the mode I plan to enter, and then separately what I plan to do under the constraints of that mode. It's a little hard to explain, and I'm sure acolytes of other paradigms have their own philosophies, but it fits in really well to my workflow.

It's a subtle thing in the limited world of text editing, but I definitely miss the semantics whenever I leave it, whether to a terminal or a browser or whatever. So for me, it comes down to wanting to bring the cost of task switching closer to what it is in the editor.

This is true for smaller companies, that hire for targeted roles, take the time to write good job descriptions and may even think a bit about what they are doing, because every person they hire makes or breaks the company.

The moment a company enters growth phase and they need a lot of talent, nearly everything goes out of the window. Most (not all) job descriptions become generic and less thoughtful and they resort to generic technical questions in interviews, simply because there aren't that many candidates who have relevant backgrounds (e.g. I need someone to work on deployment systems, but you have payment systems background) and they can't wait forever.

Obviously there are exceptions on both sides, but this is generally how it pans out, in my experience.

Respectfully sulphur is air pollution and causes significant harm.

From Wikipedia (section of Environmental impact of shipping: Conventional Pollutants)

"...Of total global air emissions, shipping accounts for 18 to 30 percent of the nitrogen oxide and 9 percent of the sulphur oxides.[15] [16] Sulfur in the air creates acid rain which damages crops and buildings. When inhaled the sulfur is known to cause respiratory problems and even increases the risk of a heart attack.[17] According to Irene Blooming, a spokeswoman for the European environmental coalition Seas at Risk, the fuel used in oil tankers and container ships is high in sulfur and cheaper to buy compared to the fuel used for domestic land use. "A ship lets out around 50 times more sulfur than a lorry per metric tonne of cargo carried."[17] Cities in the U.S. like Long Beach, Los Angeles, Houston, Galveston, and Pittsburgh see some of the heaviest shipping traffic in the nation and have left local officials desperately trying to clean up the air.[18]

This is one of the things that is at the heart of many arguments about "deep culture", bigotry, sexism etc -- and why people so often talk past each other. If an actor is blind to the effect of their actions, they are difficult to convince that they probably should change their actions. To them, their actions don't have any effect (or given the audience, their functions aren't as side-effect free as they think they are... ;-).
Congratulations on the birth of your daughter. You won't regret the good fortune of any time you can spend with her before she grows and goes.

My spouse worked four day weeks in all sorts of configurations for many years. My observation is that the rhythm of the workplace makes a difference over which days are better to take off. Sometimes Mondays matter a lot, sometimes Fridays, sometimes Wednesdays, and in some environments weekends. If you're off on a critical day of the week then you're always running a bit out of sync.

There were times when the split weekend...particularly Thursday off seemed really good. The three day weekends were good if we were going to travel but Mondays and Fridays aren't always the best days for running errands.

Three days off Sunday through Tuesday seemed to work pretty well. Two days for errands provides a lot of options. Sunday, at least in the US, syncs up better with everyone else's workweek.

Good luck.
