Why can't a church use a general purpose social network framework? How are the constraints/feature-needs different for a non-church group?

I'm asking from a place of honest curiously. Could a non-religious community group use this? Could a church get by with a social networking tool built for non-religious groups?
Hey! So, we store the whole slide. In terms of deltas, we found the easiest way around it was a combination of tracking the slide through it's markup (OpenXML sucks, but you can extrapolate some UUIDs which help with tracking.) A lot of our analysis actually comes from the images themselves though, as they are an easier format (I.e. to help us see if the slide has changed.)

Ah, so you have to have two dots... I suppose the first one denotes the floating point value, and the second denotes the prototype accessor. Very clever.
I mean, it pays my bills. But they're mostly large corporations that hire consultancies that specialize in this sort of thing, rather than hiring freelancers--much less posting about it online.
To me this just sounds like poor company/project management and passing the buck. I guess I'm envisioning a more healthy/well-managed environment, but maybe those are in the minority.

Does it offer similar features to Dokku or is it more like Deis?
"[W]hat is your favorite programming language / platform and why" while a reasonably good open-ended question, students just haven't been exposed for long enough to different languages/platforms to have an opinion, although this question (as almost any other) will certainly have the "hacker in my own time" types talking.
Why are you not charging money for this?

At the very least, you should offer a hosted version of this (borrowing the wordpress.com/wordpress.org model would seem the best plan) so that non-technical churches could click a button and just have it magically spin up a website and start billing their card every month.

Seems a bit silly looking in from the outside that you'd spend seven years building something that's clearly worth selling, then refuse to sell it. I wouldn't be surprised to see a few "church.io hosting" businesses spring up within a week if you don't build that option yourself.

> In fact, Ranter says it is more common for an accident to happen just one day after another crash than two, three or more days later.

As written, a poisson distribution wouldn't explain this. If you have a crash on day 0, then a crash on day 1 is no more likely than a crash on days 2, 3, etc.

Day 1 is the day most likely to have the next crash, but it's no more likely to have any crash.

(It could easily be the case that Ranter actually found "...just one day after the previous crash than two, three or more days later", and this subtlety got lost somewhere down the line.)

Yeah, the startup costs of helicopters are large. A Marine quartermaster once told me that it costs $N,000 just to turn a military helicopter on, because after you turn it off you have to do a bunch of maintenance tasks no matter what. And chopper technicians aren't cheap.

As far as I know it is completely Dockerfile-based, whereas dokku utilizes Procfiles. Therefore you could build and start any Docker container you like.
An event doesn't have to be purely random (whatever that means) to be an accident.

An accident is something that happens unintentionally. Though I'm sure many crashes are down to genuine negligence, I'd be surprised if most crashes are deliberate, even indirectly (e.g. "Whoops! I've cross-threaded this bolt, oh well, I'm sure it will be fine" vs "Ha Ha! I'll cross-threaded this bolt. That'll make the plane crash one day!").
At my work we use Codility. Every applicant is given a link to a codility test and the decision to proceed to phone screen/etc is made based on their result. There are some exceptions made, i.e. it's not a flat "you need to score at least X" but it resolves the "can you actually write some code" question up front.
I'd second the question in the form of a recommendation. From what I see in the screenshots, it seems like fairly minimal changes would also allow you to also pitch a variant of this as a tool for user groups, non-Christian congregations, and other such communities. Very nice looking tool!
I'm not saying it to be negative. Its the standard way to get any type of endevour that needs a network effect(hype) to get off the ground. When starting a band its really hard to get people to come to your shows and listen to your music. But if you get together with a group of other like minded bands and start pumping each other up, it looks like you are already popular and attracts attention. Standard scene building stuff.

I just wanted to clarify that Product Hunt does not appear to be an organically created phenomenon, but a very engineered process that from the looks of things was very well executed.

I could also be completely wrong.
It is more like Deis. A miniature version :)

Fuzzy file finder was a thing I missed the most. Fuzzy-other-things-finders like ido and helm are there and work very well, but fuzzy file finding is either slow or incomplete with most solutions. So I found one plugin I liked - https://github.com/justinweiss/fuzzy-find-in-project - rewrote most of it and now I use it exclusively: https://github.com/piotrklibert/ffip

It's documented in the code - more or less - and I'm very happy with it, especially with having multiple directory sets I can change between (which I implemented recently) and how fast it is (aside from initial caching done by the ruby backend).

I actually never thought about releasing it publicly, so the readme is non-existent and the Ruby script is hacked with hardcoded ignores, fonts are not customizable, and it's even possible that I hacked the Ruby gem source at one point. I could clean it up a bit if there was some interest in it.
From my experience with local administration here in Italy, I think that a big big problem in doing this is that most of the development work is done by private contractors which, understandably, want to defend their economic interests. Mixing in voluntary work would be very difficult, also because individual volunteers in general aren't dependable enough for anything that is really necessary.

If you want to do something small but that could bring results for sure, my suggestion is to contact some individual department and offer to do for them something that is "nice to have" but they don't have the resources to do. Very often (at least here) the cultural departments have little resources, many small projects/events, and it would be easy to create for example a website/page/small tool.

If instead you would like to do something with a bigger impact, I think you could evaluate collaboration with other developers for some open-source building blocks for software pieces needed by most public administrations. But it would be much tougher.
Hey! Great questions: there is a definite need to collaborate online in some form. This 'collaboration' is currently emailing around the versions. We'd like to think if you can make a process that is just as easy as that, you're in the money for the majority of users. Plus, this is a really big pain in the arse for people, so they tend to look for solutions.

Re GDocs, Prezi, etc: we definitely could in the future, but PowerPoint is still the ubiquitous solution for making presentations for the large majority of people, so will keep us busy for a while. Plus, PowerPoint users are in much more dire straits as to existing solutions than GDocs ones are (we are fans of GDocs, but realise that most people cannot use it because they can't move away from MS Office).
Consulting (and services in general) is a low-margin business. You can only increase revenue by tricking young college grads to work 80-hour weeks at low pay.
I was more interested in your personal feelings about it, since the license doesn't forbid this scenario. I'm glad you have positive attitude toward it. Great work, Tim, thank you for it! Although I'm personally long lost for any church or shrine, I'm glad that local communities now have one more good tool to cooperate.

"Church" definitely is the generic English word for place of (particularly, Christian) worship (or, similarly, for the actual worship services), largely as the result of it being the word used by the religious groups that were dominant throughout the entire evolution of modern English for their places of worship.

Yes, there are certain groups that object to that for etymological reasons because "church" also is the English word for the body of believers, and who don't use the word that way, but that doesn't make it any less a normal (and, in fact, the primary) meaning the word has in English.
There's a queue for that.

"But the chance the next crash is on 3 August is (364/365) x (1/365), because the next crash occurs on 3 August only if there is no crash on 2 August."

What I was always told when I worked as a nuclear power operator in the Navy is that it's not so much that the people could not be found and trained, it was that on anything smaller than a carrier the engine room crew ended up being half the crew of the ship. The larger engine room crew size necessitated designing the entire ship around a larger ship crew, which introduces a whole lot of other logistical and practical concerns.

I think it's worth spending a while with user-level C (maybe complete 1 or 2 nontrivial projects) before attempting to write kernel modules.

There's nothing wrong with giving stuff away for free. Many small churches already have budget problems and phobia of change and technology.

But offering a completely optional hosted version is a good idea for churches with more money than technical prowess.

>Don't police helicopters usually have thermal / infrared cameras? There's very little chance this drone had an infrared camera, correct?

The one in question more than likely used a normal visual spectrum camera. Cheap, repurposed security board cameras or GoPros are the norm.

FLIR cameras are available[1], but they're very expensive, so, yes, it's very unlikely this guy was using thermal imaging.

>What is the max range on a reasonably priced drone these days (transmitter range or battery range)?

The answer is a solid "it depends." For a multirotor, your biggest limitation is battery capacity. 10-15 minutes of flight time would be above average.

As far as radio systems go, again, it depends on the frequencies and antennas being used. The most common systems use 2.4GHz for control and 5.8GHz for the video downlink. 1-2KM is pretty typical. A fixed wing with a 433MHz/1.3GHz system and directional antennas can potentially make 20-30KM flights. This is all with readily available equipment at fairly low cost.

Can the idea be combined with that tech; sorry forgot the name; being demonstrated for cell phones where many small antennae track where the target cell phone is to improve signal quality?

Instead of free beaming, give each device a beacon so it can be located? (I am really not even familiar with viability of any wireless charging solution so shooting from the hip here)

10 Apologies I Will Never Again Make as a Startup CEO
Great work. Please keep adding examples!
Hi.

Let's pretend that I'm an intermediate developer with no knowledge about sysadmin or even deployments. How would you break this down and ELI5 [0].

How does Packer fit into all of this (assuming I'd use Digital Ocean). What's Vagrant for? What does Virtual Machine do here? Do I need these three machines on the target VPS or only on my local development machine? To add my DO keys do I need to ssh into vagrant once it's up and running?

You provide the octovagrant box, is it secure? Is Vagrant production-ready or is it not part of the production mix? You've got 6 cookbooks listed in the cookbook repo. Do I need all of them? How do I use/install each of them?

What does Docker do? Once I've done all of this setup work, how can I push up all of my code to the desired VPS? Do any of the defaults have security provisions and set up ufw rules to only allow port 80 etc [1], disallow root access, only allow ssh access and all of that goodness? If I use this over manually provisioning and securing servers, do I get sane and secure defaults?

That's a lot of questions, but I may not be the only one asking them, so if I may so bravely ask, ELI5?

Accident just means unintended. And while there are causes, they may now well be unknowable, in which case a statistical look is probably the most interesting look you can justifiably make.
people with the ability to immediately fly a drone > people with the ability to immediately fly a helicopter. The drone/rc/quadrocopter IS the news. The fact that one guy put a camera in the sky is news.
At a guess it's probably tracking aggregate attendance, ie: 60 people were at this service. Like page views in google analytics.
Yes, that's what I'm looking for what I ask this question.

There's no wrong answer, but if your resume says you've developed projects in C and in Java but you are not able to articulate any reasons you might pick one over the other, I'm a little suspicious. It doesn't even really have to be languages; I mostly just want to hear you have a well-reasoned opinion on something.

My wife worked at IBM for many years and every year, like clockwork, right before the quarter was up, they'd shut down the power to entire IBM sites for a day or two to save money. Everyone would be told to work from home. That's how important cost-cutting is to IBM.

There are plenty of niche social networks out there. I don't see why having one for churches needs special justification.

That being said, being a churchgoer is a very distinct social experience. The types of relationships, the need to moderate at times, the sensitivity of some conversations, etc. It makes a lot of sense to me that you'd have a specialized tool for that experience.
I read a book once - I think it was the Gift of Fear (but I might be wrong) - that said that plane crashes often occur in clusters, same with other tragedies like mass shootings at schools etc. The author suggested this was because people who might do those things - or in the case of pilots, pilots who might want to commit suicide and take the plane down with them - get prompted to act when they see other incidents have occurred. So according to that author, these events are not random.

Obviously a civilian plane being shot down would lie outside this theory (he suggested more plane crashes were due to pilot depression than mechanical fault/other factors).

I could imagine that those sorts of people, the ones who let interviews go to their head, the ones who feel the need to impose their will on the interviewee and the interview process, are likely to cause problems with the candidate if he/she is hired.

Have you seen people who mesh perfectly well but go to hell in a handbasket when you throw them in an interview? It feels like that is something, however arbitrary and difficult to test, that you'd catch when you interview these people - avoid anyone whose fitment is questionable at all, and that your statement is merely a byproduct of not catching these bad interviewers before you extended them an offer.

I completely disagree that the question is a bad question. He does not say there is a right answer, only that they are able to make a competent argument about what language they like and why. The point of the question is to see if they have actually put much thought into developing software. Enough thought, in fact, to have an opinion on what they like and why. Furthermore, it tests their ability to verbalize convincing arguments for their opinions with logical evidence for those arguments. These are skills that are needed when working in a development team.

Now if he is saying, "well they said python and I hate python, so they are wrong!" Then, obviously, that is not a good interview tactic. But I didn't find that to be the case from the way it was presented in the article.
No, it literally means what you said above, and the majority of applicants literally can't do it. It's shocking and sounds ridiculous, but is true.
Also a terrible interview question.

I don't know every conceivable reason why a church would track attendance, but one reason: churches that use / sing "cover songs" (i.e., not public domain, not original compositions) need to pay licensing for the songs, and one of the variables on how much the licensing costs is the average number of people in attendance.

While I don't think he needs to sell it, the hosted option is definitely something to look into. I saw the "Install in the Cloud" option and thought "Oh cool, they'll provision a DO droplet and install this for you!" Unfortunately any church that wants to use this is going to need someone technical enough to handle the installation themselves.

That said, it's open source - so anyone (including me!) is free to set this up.
