Is working at a startup mandatory as part of curriculum then?

Also, every startup has tons of different problems at micro level even though macro themes are consistent (e.g. getting new customers etc.). It will be hard to generalize problem solving across startups.

I agree that Everpix couldn't find scalable business model for their product. But what I'm saying is you may not necessarily need MBA to find market/business model.

You're not even speaking coherently. They aren't sabotaging it by not adopting it. That's just called... not adopting some arbitrary spec.

Being published by the IETF doesn't mean anything. The IETF has a spec for SIMPLE, too. Should we blame all XMPP networks for sabotaging that "standard"?

Why should a third party have to do something just because you don't like how they run their own networks?

Yes. We moved back to our own infrastructure as well. But AWS has a broad range of services. I can imagine storing photos on S3 makes sense for a startup like Everpix. Because, you don't need to worry scaling on storage level. Sometimes it makes sense to pay a premium, but it should really be tied to your growth metrics. If you see a month to month growth to which you can't keep up with updating and migrating your own infrastructure, then make the move to AWS or another big cloud vendor.
This should be fairly easy to price out, right?

I suggest you start by simply comparing the cost of dedicated hosting-provided hardware. This is the middle ground between owning your own stuff and something like AWS.

Pricing out the cost of owning your own servers can be tricky since you need to account for a number of factors:

* Initial cost of hardware - don't forget to include things like network switches, remote console devices, etc. - you may also want to buy something like a remotely accessible power switch so you can forcibly reboot machines

* Rack space costs

* Bandwidth costs

* Sysadmin time to manage the hardware (you already need a sysadmin to manage things like backups, logging, etc.)

* On-site remote hands if your rack host is not physically near your sysadmin

But regardless, I'm pretty sure that _anything_ ends up being cheaper than AWS once you get beyond a fairly small number of servers. The big advantages of AWS are integration with other services (storage, load balancing, etc.) and the ability to spin many machines up and down very quickly.

However, if you can tolerate waiting a day or so to provision new servers, dedicated hosting-provided hardware is almost certainly going to be quite a bit cheaper.

You could also compare this to something like Linode. Again, you lose the ability to provision new machines almost instantly, but they are pretty quick to bring up new machines (minutes, not hours or days). They also have a number of nice integrated services like backups.

Finally, you can also do some sort of hybrid setup where you have core stable services on dedicated machines but still spin up AWS instances to deal with bursty computation needs.

Isn't he glossing over some actual value in a private Lavabit-like setup?

He's quite right that there are several steps where the server must "avert its eyes" (this is a good way to explain it) to keep the plaintext password, decrypted private key, and resulting plaintext email safe.

But still, if the server averts its eyes at those points, once the user has logged out of webmail, the email is again safely stored, and (as claimed) even an NSA-compromised Lavabit can't access them until the user signs in again (if the server has been modified to capture the password or private key).

Well... except for the loophole where the emails were transmitted plaintext via SSL, NOT using perfect forward secrecy. In that case, anyone who managed to capture that SSL-encrypted traffic can decrypt it after the fact if they can get the SSL private key from Lavabit's servers.

And honestly, that was the weakest point. Once Levison shut down Lavabit (preventing Snowden from sending in his password again), Snowden's emails were safely locked away, except for that last loophole.

What this all suggests is that an open source version of Lavabit could actually be more valuable than the original service, as long as SSL is configured for perfect forward secrecy.

I.e., set up & secure your own email server (or let a trusted person do it for you), with code that verifiably averts its eyes at the critical moments, and leaves your email history safely encrypted when you're not accessing it. If you ever suspect your server may be at risk or has been compromised, you simply don't sign in again.

Marlinspike is right that the best solutions are in sticking with email clients (not webmail... unless you want to dig into the problems of real encryption/decryption in JavaScript, and verifying the JS you've just downloaded). But -- those solutions don't exist yet, and may not exist for years to come.

A private Lavabit seems like a pretty solid solution to me, and certainly far better than throwing up your hands and going with gmail and friends.

It's somehow ironic that a service provider whose name contains 'ever' and promised to store your photos for ever has to shutdown after only two years. As a user, I tend more and more to go with well established providers to avoid such situations. 40 days isn't much to migrate away from a service either. On the other hand, users have probably to be glad that the service wasn't shut down with immediate effect.

I have been knocking my iPhone 5s for the past 10 minutes, but nothing is happening.
On my mac, it seems that everything has been setup correctly, I can see my iphone name in the unlink button, so everything must be set up correctly.
On my iPhone 5s, I see my personal icon for my macbook Pro retina 13'' and a big picture of a macbook pro. I have been knocking everywhere in my iPhone: the picture of macbook pro, my macbook pro personal icon, the white spaces around the app, my home screen, notification center, my locked phone, and nothing seems to happen.

I understand that you are trying to make this as simple as possible, but things you assume to be obvious might not be obvious for others. For example, where do I knock? Does the phone have to be awake? Does the app have to be open? etc.

Also, your app seems to be failing silently. I have been knocking all over the place and it would help tremendously if there was an alert telling me what had gone wrong. That way, I can email support and pinpoint exactly what is wrong. As of now, I have no idea why your app is not working.

Finally figured out what I was doing wrong. Put your phone flat on the table. Then tap twice on your phone and you should see rings show up on your macbook pro. Your phone can even be locked.

Do not hold the phone in your hands while you tap it. I was holding the phone in my hands before, which causes the taps to fail to register.

How is this "Cool C Programming"? What am I missing?
Seconded. I used to work at Betterfly which is in the same space and our lack of focus on a vertical ultimately really cost us. To our VC's credit, they always pushed us to pick a vertical--even if it was something completely random. Building a general product for everyone is super hard and you risk satisfying no one. When I moved on from the job to my own start-up, the single biggest lesson I took was to pick a vertical!

O'Reilly Solid: Conference on Convergence of the Physical and Digital
sadly, this is my first time hearing of this service...
Wouldn't Lavabit be better if all decryption was done on client side, either with javascript or a client side add-on/extension? This way the only thing that is ever on the server is the public key? The only thing left would be if it had been in a man-in-the-middle attack... which is always an issue on the internet unless every part is encrypted which is hard to do... though internally it could potentially be safe as it would not ever be sending out of itself and emails being sent would also be encrypted client side using javascript/add-on/extension...
(also have the keys generated on client side)
yes this would inevitably be a large client side program but for security it would be worth it.

It should probably be pretty trivial to roll together a TimestampMod equivalent using a similar methodology as git-notes. Hell, just store a git-note for every commit in a non-standard ref; each note would have a printout of the tree and corresponding timestamps. To reapply timestamps, you'd just have touch run through the git note, re-touching every file to have the appropriate timestamps.

Like others have said though, I don't understand what a use case for this would be. The page for that Hg plugin seems to indicate that it is just meant to ease the transition to version control, for users who don't yet 'get it'.
I know people who manage server farms for medium to large companies. They lease their servers, and when the lease is over you can often directly contact the lessor and learn they have a room of such servers just collecting dust. Likewise, my colo has customers who abandon accounts - leaving perfectly fine hardware behind. Just keeping one's eyes and ears open for the opportunities pays off.
But your photos are much more important than the life span of one company. So if you're truly trying to solve photos, it has to be as an open source project.

It's possible in both cases.

I doubt (but haven't confirmed) that a standard renter's policy covers damages arising from short-term rentals.

Description of noisy neighbor problem #6 lacks some depth.

AWS noisy neighbors problem is very often misunderstood. CPU steal time under linux does NOT mean that somebody is stealing your CPU. It simply means that you wanted to use CPU and hypervisor has given it to another instance. This may happen because you have exceeded your quota or scheduling algorithm selected another pending instance at this very moment and it would give CPU back to you a bit later. In the end in both cases your instance gets fair share.

Great detailed explanations of steal time: https://support.cloud.engineyard.com/entries/22806937-Explan... and: http://www.stackdriver.com/understanding-cpu-steal-experimen.... The latter article is mentioned by OP but seems to be not fully read/understood.

Why does killing and restarting instance help? It likely moves instance to different hardware node with less active neighbors. When your neighbor is not active your instance can use CPU idle cycles of your neighbor! You sort of become the noisy one. Still hypervisor would prevent it once neighbor starts to fully utilize his CPU quota and you are back to square one.

Amazon does not oversubscribe CPU according to their CTO: http://itknowledgeexchange.techtarget.com/cloud-computing/am...

Amazon specifically states that t1.micro instances do not guarantee CPU performance:
"Micro instances are a very low-cost instance option, providing a small amount of CPU resources. Micro instances may opportunistically increase CPU capacity in short bursts when additional cycles are available. They are well suited for lower throughput applications and websites that require additional compute cycles periodically, but are not appropriate for applications that require sustained CPU performance."

While CPU sharing is pretty well documented noisy neighbor problem still exists for network and disk resources being shared by multiple instances on the same hardware node. The only way to detect these problems is to track network throughput/loss rate for network and IO stats for disk.

You are guaranteed to avoid noisy neighbors CPU problem by using AWS dedicated instances:

I am currently feeling very tied to Mac and iOS due to my reliance on OmniFocus... Pretty much everything else I use is multi-platform, and I want to break this tie so I can just carry one laptop for work (Linux) instead of 2.

What apps do you use for task management, and that are cross platform? For my beginning searches, there is nothing that equals OmniFocus for task management.

To give you an idea of my needs.. I'm a contractor, I have 2 clients. I also contribute to an open source project, part of that is sponsored by one of my clients, the other part is self driven.
