Do you find them that much better? We're a small HipChat-using company who moved three teams over for a month, and the communal response was "eh?". It's no-doubt prettier and easier to write integrations, but for the core competency of chatting, the two were very similar (and most people preferred the native HipChat apps to the Slack browser one). It's big selling point for us was integration with Google Docs, and in testing we found that it didn't work that well.

It's also 3.5x more expensive. In absolute terms that's not much (<$400 a month), but no one could point to $400 of incremental value in it. If we fully embraced it and turned off emails for those teams, would we see it? Maybe, but we'd still need emails to deal with external vendors, and there's no way that we'd get non-developers to see it as an email replacement.
I'd love to hear the substantial difference between Clash of Clans selling you gems that make your building finish faster and LOL selling you XP boosts?
Just implement an FPGA in Verilog, then use that FPGA as your target. It has the added bonus of making your bitstream portable across Altera, Xilinx, Lattice, etc. One could use genetic algorithm to map the search space so that the virtual fpga compiles cleanly using available resources of the hardware.
At this time, the title of the article is actually "ALMA Reveals Intense Magnetic Field Close to Supermassive Black Hole", and I believe it's a substantially better one.

Sketchwrite is a hybrid notepad that combines the free-form nature of drawing with a line-based text editor. This allows sketches to be placed anywhere while maintaining their relationship with lines of nearby text; all without needing to tediously drag things around or worry about positioning.

The way drawings and text relate may seem like a subtle change in perspective, but it opens up an entirely new way of interacting with digital paper. You can even draw around words for emphasis or pointing as you would in a physical notebook.

Sketchwrite works on any device, so give try it from anywhere and let me know what you think (or if you run into any issues!).

How does that work exactly? Of course, my intuition is that lower air pressure means less to "push off of" but also less drag. And you've got certain constant overhead, like internal friction. Is there some sweet spot of air pressure where you'll get the best efficiency?
"The Art of Commonplace" by Wendell Berry. It's a collection of his essays on just about everything. Usually read one, and set the book down to gather the pieces of my blown mind.
While you're right in a broad sense, I think in fairness slack has a lot of polish where others tools don't -- they get a lot of UX details right that seem "obvious" because they are getting them right. But they're actually far from trivial.
Incredibly true; for something as simple and necessary as messaging, the company I work for has:

1. A company-wide and approved solution (proprietary) that's very buggy.

2. A jabber server someone threw together so everyone could use their client or choice.

3. Google chat (through various clients).

4. MSN messenger / Skype.

And they all get used by different people for different things. It's very frustrating. Switching to a new thing would be a non-starter, probably (and we couldn't move to Slack anyway, but that's another issue).

What the other reply said is true, Slack by default only sends mobile notifications when you're 'away.' In addition, by default, it waits 5 minutes before sending notifications (this can be changed).

The v2 Android app is currently in beta - I've been testing it for several weeks. It's lightyears ahead of the current release version which is admittedly pretty faulty (no caching means that resumes are very slow). I've also found notifications to be more reliable. Perhaps give it another try once they ship the v2 Android app.

What's wrong with VirtualBox shared folders? Also, Windows-native sshfs-alike is SMB.
The problem with trying to kill email is that you're never going to have everyone migrate off of it. It's going to have to be some type of layer on top of IMAP that then moves to a more sophisticated protocol. Google has done such a great job with NLP/AI/ML that spam from facebook, twitter, etc. are all put into a separate tab that I only see when I want to. When I click on an email about a flight, it gives me updates on the status of the flight. Gmail also makes it seamless to share docs. I could make a clean interface for email groups using the Gmail API and have the same product as slack. What am I missing here?
> but so far as I can tell nobody, at least in the hobby size quadcopter world, has done so

It's not the motors that are the problem. They can spin freely any direction. It's programming the ESCs to be reversible.

Anyway it's already been done a hundred times over:

- Fixed pitch props but reversible ESCs https://www.youtube.com/watch?v=UoReJULASkw

- Variable pitch prop styles exist such as HobbyKings Reaper https://www.youtube.com/watch?v=mAFxkHAiimY and Curtis Youngblood's StingRay http://curtisyoungblood.com/V2/products/quadcopters/stingray....

Autorotation on quadcopters is possible with the variable pitch configuration.
One thing they get really wrong is embedded code snippets. The formatting, chrome, and UX around snippets is not as good as HipChat.
Can you highlight a few of the reasons you love it, in comparison to HipChat? When we ended our trial month and announced we were going back to HipChat, the biggest reactions was "OK".
>No one in technology should ever find themselves uttering these words. It's like asking for it.

It's a completely different matter to be saying the same words in private vs in a public interview that will be read by millions of readers. A CEO must say this (or something to the general effect while being PC) when speaking in public. Doing otherwise can only have negative consequences with respect to employees, customers, etc.
Slack executes so much better at every level that stating it's a wash between Slack and HipChat just doesn't compute.

One key example is the multiple teams feature: the ability to have multiple accounts logged in at the same time, and the ability to easily swipe between them on iOS or toggle on desktop is a huge advantage.

A quick look at HipChat indicates this still isn't possible [1].

Considering more and more people wear different startup / company / organisation hats not having this feature is a great way to limit participation / growth in a communications platform.

That Slack had this feature at the outset for me meant I've already spread use of Slack to multiple orgs and participate in all of them at the same time.

Chargespot makes a charger that has both Qi and Powermat, it isn't a difficult problem to support both:
http://www.chargespot.com/documents/ChargeSpot-Product-Sheet...
WPC 1.1 is Qi
I belive the only reason Starbucks has Powermat only is because they were provided for free by Powermat. The fact is that built into devices, Qi is far more common, but where or where is Apple?
How can you possibly reconcile the idea that demos would somehow beat out micro transactions if only they had their own category despite the fact that they fail living side by side with microtransactions?
If you sold your app for $600 I bet you could create that kind of experience. And if Apple sold phones for $2 you can bet the buying experience would be a lot different.
I think we can flip this upside down and frame it in terms of "what are they doing wrong wrt the product and design"?

I think the list will be much shorter for Slack compared to its peers.
Mediocrity principle
I thought it was fairly self evident that I used flashlight apps as a stand in for any specific segment you want to isolate in the app store.

That said, here's something to think about: I myself have paid real money for a flashlight application for my smartphone. Why? Because I wanted a flashlight app that didn't take three screens and button presses to get to light, and I also was a little leery of what the ad supported apps were really using the network for, so I wanted one that didn't require network access. This was a few years back and on Android, but I think the point is applicable, what you think you know about a market on a cursory review may not turn out the be correct upon deeper inspection. Some people made money on these apps, either through advertising or through the initial app price.

Flashlight apps may have been a poor choice on my part, but I think the original point stands. How does the market for tower defense games look? What about platform games? Do you think the average developer in these markets markets makes as much as they did 5-6 years ago? Do you think the advertising cost is the same?
> people can go years slowly dying from something that they could fix with a few pills from the corner pharmacy, if a doctor would deign to "tinker" rather than working from theory.

This is a principal-agent problem. Doctors don't have much incentive to cure you. They have a strong incentive to avoid malpractice lawsuits. Thus they are extremely risk-averse.

Either these takedowns need to be documented in the report, or the reasoning should be on the repo itself (i.e. "broke rule x" or "offended too many users" (which hopefully isn't a reason something is taken down)).

> "it's becoming increasingly difficult to justify a >$5 price for a game", but I haven't seen any sign of that being true

But isn't that the crux of it? If you are charging $5 per game and you spend $100k developing then you simplistically need 30k installs just to break even. When the app store was small and you had a good chance of being the only app in your category that was not hard to achieve. When you are just 1 of 100 other apps in your same category it is 100 times harder to achieve. If you could charge $20 or $50 which was historically how software was priced then you could tolerate 4x - 10x less installs, but the app store culture has been permanently set now such that it will not tolerate that. 99c apps got Apple off to a great start, but it has locked in a situation where only the largest (or most sophisticated) developers that can reliably get to the top of the charts can stay afloat.

There are quadcopters with collective pitch and mechanical linkages to a central motor. They should be able to autorotate in theory (although there might not actually be enough rotor momentum), and not to mention fly upside down. Of course, you don't get the mechanical simplicity of 4-motor quadcopters, and there's still no redundancy for propeller loss.

By the way, it's worth noting that there are also quads with 4 electric motors that can reverse so you can fly upside down:

> I've never asked anyone to change. Note how I described getting stuck and hearing chinese pedestrians admonish each other to let me by.

I've been that pedestrian. We're walking on the pavement. We become aware of someone behind us on a bicycle, who cannot get through unless we move aside. My friend suggests we stop at the side and let the bicycle pass. I reluctantly do so.

Did the cyclist ask me to change? No. Did the cyclist inconvenience me? Yes.

> Bicycles on the sidewalk are fairly common. They're not dangerous.

I was walking to work in Shanghai, ~90 minutes ago (shortly before 7am). A cyclist on the pavement nearly hit me. He was a foreigner wearing a business suit. He was cycling on a pavement which had explicit markings and bollards to separate what was a pedestrian walkway into two lanes (one for cycles). He was cycling along the (narrower) pedestrian part.

Gladly.

First off, i need to clarify how the two work, since they work substantially different to one another:

LOL boosts come in two variants, but the net effect is the same: XP income per time unit played is doubled. You can spend more money to have them apply to more time units played, but you can't increase the effects of the boosts. They do nothing else. (I assume rising in level also pushes one into higher level matches against stronger players.)

Meanwhile CoC gems do a multitude of things: They permit access to items that are otherwise inaccessible and increase competitiveness. They are very powerful multiplicators in allowing constructions times (that i assume to span days in the extreme) to be entirely removed. Lastly, they allow the player to ... play more by restoring heroes.

So, the practical effects are:

LOL XP boosts do not increase competetiveness of the player. In fact, they can detrimentally affect it by pushing a player into high level matches before they themselves earned the necessary experience to function well in them. Further, players are discouraged actively from spending too much on them, since they may be stockpiled, but not increased in power and past a certain amount of stockpiling it's senseless to buy more.

CoC gems increase competitiveness fo players massively, in some cases (build times) applying literally infinitely large multipliers compared to the x2 multiplied of LoL xp. Further they also serve lock the player out of playing the game unless the player spends real money to buy and spend them on healing their hero.

TL;DR:

LoL xp boosts are fixed subscription fees with a maximum cap.

CoC gems are literally consumable cheat codes designed to encourage unlimited spending.
Honest question, outside of writing your own bot are there any real IRC integrations for even half of the services Slack integrates with? It's really useful to set up monitoring services in a dev channel where we can not only read errors, but share code snippets with pretty formatting, Github integration to let us know when a PR has been opened to fix the issue, and then Trello to manage features too.

Not to mention the integrations outside of developers. I haven't worked in enough large companies, and never as a nontechnical employee so I'm not sure what sales teams were using for communication but I doubt IRC was their cup of tea. I imagine they used a lot of email, maybe some CRM communication but that's still not as useful, or rather I imagine it's less useful than Slack. Having a single place to discuss Stripe purchases, hiring with Breezy, MailChimp et cetera that isn't a gigantic email forward sounds seriously useful and I don't know that anything like that exists on IRC.

There are alternatives like HipChat, but they clearly didn't it the mark the way Slack has.
It's a slang word and other people i see online like to use. It's never gone mainstream since understanding the meaning behind it requires actually putting in some time to study psychological effects.

To expand on this, the desktop clients keep you active for much longer than say the web client. I was also having these issues so I asked for a clarification from their support.

I stopped using the desktop client for this reason and now I have a separate window open for the web client. Push works much better for me now.

Microsoft's actions that lead to its conviction did not benefit consumers in the immediate term. It hurt consumers both immediately and in the long term. And their intention was, as proven in court, to harm competition in the OS market; not to integrate stuff for a better user experience.
