As I recall, this is severely limited in that it does not correctly support sub-searches or pivoting between different indexes. Any news on if this has been improved?
Gravity doesn’t have a speed. It creates an acceleration due to force. The bullet is accelerating over a great distance until it reaches terminal velocity (where the air resistance counterbalances any gains in acceleration).
The easiest way to think about it is in terms of conservation of energy. All the kinetic energy the bullet has at the muzzle is converted into gravitational potential until velocity hits zero. At that point, gravitational velocity starts getting converted directly back into kinetic energy. If not for air resistance, the bullet would reach the ground at roughly muzzle velocity. However, air resistance on the way up zaps some of that energy and presents a velocity barrier on the way down.
There are two components - horizontal and vertical. For a bullet fired straight up, horizontal component is negligible, as the bullet will spend enough time in flight for it to decrease due to air resistance.
The vertical component is primarily determined by sectional density. Tumbling bullet spends a lot of time flying sideways, so its terminal velocity (where air resistance equals weight) is way less than muzzle velocity.
By "speed of gravity" I assume you mean terminal velocity[1].
If not fired fairly straight up the bullet can maintain a ballistic trajectory[2], rather than being in a vertical free fall. In that case, the higher speed compared to the terminal velocity is simply because it has yet to shed the speed it acquired[3] when it was accelerated out of the barrel.
It's not. The magnitude of the velocity of a falling bullet (in the low m/s) is many orders of magnitude lower than the speed of gravity (which propagates at the speed of light)
I can show you plenty of tests "proving" that Newtonian mechanics are correct too. General relativity doesn't correctly predict things at quantum scale.
Ouch. If Troy Hunt of all people can make this mistake, it can happen to anybody. HIBP is an awesome service funded totally by donations, so it's too bad this happened. Of course Microsoft is happy to hide behind their confusing pricing model and let customers overpay for Azure without alerting them.
> If Troy Hunt of all people can make this mistake, it can happen to anybody.
Exactly this. As a low-level / embedded / non-cloud stuff dev, I've been getting up to speed through all the cloud-ification of the industry, but I'm still scared (not literally ofc) of running most things on my own on any big cloud provider (smaller ones seem more manageable).
I'm reading this and seems like being a customer of cloud services is like walking a dangeous path filled with gotchas and caveats, just jumping from cover to cover while hiding from danger, and hoping you're safe and didn't mess it up so far, "fingers crossed".
Like this tiny detail that he didn't realize was critical, so I would fall on it too plus on another 500s small papercuts: "oh I set cache up, so I hope all is well". "Yeah, no you aren't, I guess you didn't think of this detail about maximum cached file size! Gotcha, Game Over!"
Yeah cloud providers should have clearer communitacions and etc etc... but the fact of today is that they don't. So I'd never sleep well feelin 100% confident that I had covered and taken into account every minuscule detail and possible scenario that could end up being a disaster.

Another advantage is his big network that he can ask for help. There's also a chance that his blog post will reach the right person in Azure and he'll get a reduced bill.
As someone who doesn't have the same network or the "fame", I am concerned about what would have happened to me in that situation.
Remember when no-sql came out and everyone was rushing to it because "rdbms don't scale"? I'm beginning to feel the same way towards "cloud" in the Azure or AWS sense. You can go really really far with standard issue VMs from linode or digital ocean and so on. I wonder how many are overpaying for Cloud services so far above and beyond what their actual needs are.
Every cloud makes this mistake easy! You have to manually activate billing alerts for everyone because they want you to spend more snd more each month.
I am still waiting for a cloud without these dark patterns. But that will never happen because it‘s leaving a big amount of money on the table by not being hostile.
Also the billing alerts is just that an alert. They should have something in place to put a hard cap on monthly spend. That way his free website would go offline when he's spent > $X.
I see there is a spending limit for the "intro" or "preview" plans designed for students, Visual Studio users, and resellers (the "hook" part in "hook, line, and sinker").
Not for actual cloud usage, like an actual pay-as-you-go plan where this would be useful.
Yeah, there are trial accounts and things but as far as I know, none of the big cloud providers have a way to say "Under no circumstances are you to charge me for than $X per month even if it means shutting down services."
And the alerts are not instant, at least with Azure - they run reports every 24H or so, and execute alerts every 24H or so. So even if you're careful, you can still be on the hook for a couple of days' worth of spend - which could be very expensive.
Pretty sure fixing deeply technical business to business transparent-but-potentially-terrible pricing models are pretty far down the priority list on things that will get them re-elected right now (not even counting campaign donations).
Contract dispute cases might clarify it, but probably not in the direction any of us is hoping.
Not it is not. It is common industry jargon for people who work with websites. Nobody else knows what it is. If you had to pick a term to sound as inoffensive as possible for fraudulent, deceptive conduct while still sort of capturing the thing without being abjectly false you could do no better than something that sounds like a colourscheme.
"Mr Politician what do you think about $big_co using dark patterns?"
"Mr Politician what do you think about $big_co engaging in predatory death-trap pricing schemes to defraud consumers?"
What is being asked in one of those questions is clear to everybody. The other is jargon and excludes the majority of the population from understanding the intended meaning. And note, you don't have to agree that it is "predatory death-trap pricing" at all. That is simply in the above sentence an accusation. Words have meanings. That the accusation be understood clearly by as many people as possible is important.
I appreciate your point that as many people need to know the meaning accusations and that meaning is important, and I agree.
However regarding your other claims- I dont work on websites, I know the term "dark pattern". so your assertion that "nobody else knows what it is" is false. You might then argue that I'm still in tech, but that's just another goalpost that I can reach anyway: if you google for the term you'll find vox articles, explainer sites, even newyorktimes articles using this term.
So yes, it's a common place term and your assertion to the contrary does not hold any water.
> Dark patterns - this sounds like a colour scheme you don't care for.
Or craft clothing for goths?
But the "dark" comes from its association with evil: "Defense against the Dark Arts", "The Dark Lord", "Turn to the Dark Side of the Force". It's a clear implication that the people are "selling their souls to the devil": knowingly doing something "a little bit evil" to achieve their aims.
We had a similar situation to Troy's where several thousand pounds was charged in a matter of days as a result of our misconfiguration of caching in our azure app services (before that month we typically had around £800 a month costs). We emailed Azure / Microsoft and they were happy to refund us. I don't think this is their intended business model.
My understanding is you hit your bandwidth cap and that's it, no more bandwidth.
(edit) looks like that's not the case, I'm sure I used to have to buy a second instance a few years ago if I did want to use more bandwidth that was allocated
Yes, their support is amazing. I can email the support address and have a real human who knows what he/she is doing reply within minutes or hours at most.
Exactly! It is quite refreshing to not have to battle past first line to find someone with the understanding to help. No shibboleth required. Cheaper hosting, too.
If you use up your monthly network transfer pool, you can continue to use your Linodes normally. That being said, you will be charged $0.01 for each additional GB at the end of your billing cycle.
Sure that's what i am doing. A beefy dedicated machine with no bandwidth pricing. But that also means i need to do everything by my own. I don't get any of the worry-free services of AWS.
If I leave my water running then go on vacation I'll have a huge water bill too. I don't conclude my water company is intentionally trying to overcharge me. The more reasonable conclusion is: building an alert system that addresses every customer need is hard. Most enterprises (where all the customer focus is) want minimal downtime above other considerations, including cost.
This is like you leaving your tap running slightly as you go on winter vacation so the pipes don’t freeze over.
But the water company does not actually allow you to install proper taps to regulate the water so you use duct tape to do so, and due to an earthquake something falls on the tap causing your duct tape solution to fail leading to a massive surge of water, leading to your massive water bill.
Did the water company cause this? No. Your duct tape solution wasn’t resilient enough because it didn’t factor in an earthquake. But I would be justifiably mad that my water company does not allow me to install actual taps, and allows unforeseen and unpredictable situations to make me run up huge bills that could otherwise have been avoided with a proper tap.
The problem with the cloud is that the entire Internet is in control of your tap and can choose to open it and waste infinite amounts of water with no way to implement a cap.
See you when your a even more inflexible (and old) guy who makes the bet on one horse, look i give a *hit about (or anyone else) oracle, what i care for is migration without problems from one provider to another.
Hard requirement: My image can run on it (freebsd and linux), no proprietary BS, no special stuff, give me vm-"harware" make it fast, make it cheap, make it reliable, that's it..that's it.
And ATM i like oracle hetzner and vultr at most. If one of those change to my disgust i change, no big deal...just some dns rewrite.
The Oracle cloud UI is extremely slow and terrible to work with. I'd prefer shenanigans every so often than having to deal with that crap on a daily basis.
Hetzner's cloud offer is limited but they limit your possible spending by default and it's very easy to set up billing alerts. I guess they mostly do it to ensure they get the money at the end of the month, but it's equally useful for their users.
Additionally Hetzner's egress pricing is a lot more cheaper. On hetzenr you pay 1,19€/TB (1.13$/TB) vs. 90$/TB on AWS. That's about ~80 time more on AWS!
Do you have any substance to your allegation of Microsoft hiding behind their pricing model?
This is very straight forward from their view, before: almost no traffic = almost no costs, now: huge traffic = $$$.
On the other hand, it doesn't seem that Troy did try to talk to them about this and seems to want to eat the costs himself. As it was his mistake. I think that's commendable. I also think with the amount of free advertisement Troy has done for them they'd be open to this and I can imagine we might see a followup post like "MS was so nice they waived my costs".
He's also independently very wealthy. Dude drives a GT-R and AMG C-Class (as at 2017, probably upgraded by now). He got a generous payout when he was laid off from Pfizer.
Putting anything internet-facing on the cloud is as irresponsible as posting your credit card number publicly. Anyone can essentially charge you an infinite bill and you can't do anything about it until it's too late.
Maybe it's not a problem when you're dealing with millions of VC money, but there's no way in hell I would host anything in a bandwidth-metered cloud service when my or my own company's money is involved.
Correct me if I'm wrong, but Troy Hunt is a person focusing on security, not infrastructure, deployments or development even. If anyone is near making that mistake, it's people like Troy Hunt. Operators would of course see the problem easily (paying for bandwidth like that would be the first warning sign), while they are sometimes blind to other issues, like security.
> Correct me if I'm wrong, but Troy Hunt is a person focusing on security, not infrastructure, deployments or development even.
Eh, I don't know - either way he is a Microsoft Regional Director and MVP for Cloud (as well as security), runs courses on cloud deployment on Pluralsight, and has done speeches on Azure and reducing cloud bills, so if a he can get stung it doesn't say a whole lot good about my chances.
Thanks for the correction :) I had no idea he did all of those things in addition to the security work. Certainly doesn't paint Azure or him in a good light then.
So I guess one method would be to set spending-limits when you setup your account. But that'd lead to constant moments of having to bump your budget (or worse, get approval to do so from Accounting) when you're trying to work.
There are both spending limits and alerting that you could use, but would be impossible to predetermine from Azure's perspective, so they rightly ask you to.
There's an entire surprisingly-large industry built around providing better UI to the major cloud providers, so you can actually tell WTF is going on with billing, access control, networking, et c. They're so hostile that it has to be intentional.
The underlying issue is that the cloud console is owned by a single product team, and THEY decide what gets exposed - not the underlying product teams for the individual services. At least that's the case for AWS.
The result is that you get a lowest common denominator type of dashboard. And hence a whole industry of providing just a prettier dashboard on top of AWS / GCP / Azure metrics.
Datadog started with a prettier dashboard for Cloudwatch data.
Cloudability started with a prettier dashboard for the Cost and Usage Report.
And also works the other way around. The individual product teams buy development environments to circumvent the console restrictions.
For example, a few years ago, the Redshift team purchased "DataRow".
I would imagine part of the reason is because even if you have a trained COBOL maintainer, they still have to learn and understand the actual business logic of the application. Learning the language is not even half the battle. Maintaining old often undocumented code is a hard task in any language.
Indeed, I've once met someone who migrated a COBOL project to Java, the biggest complain wasn't even the Language itself, but extracting business logic from a 40-year old spaghetti codebase. Sometimes bugs where part of the business logic itself and other developers who consumed the monstrosity had to make corrections on their side.
Yeah basically, but it doesn't validate an email address (user@example.com), it validates say, the From: header of a MIME message, which could contain an email address, a phrase (like a first and last name) comments, and all sorts of dumb dumb ideas like having phrases that have embedded comments and phrases that look like email addresses but aren't and on and on and on. This RFC is a trainwreck and whoever wrote it should feel bad about themselves.
Google DNS is reporting back a different IP for me when I query perl.com (same subnet though). It's all part of the Google Cloud /13 block.
Sure it may have been used for malware, but given those IPs float between ephemeral cloud instances, it does not mean it is currently being used for malware.
I just use emacs. It has enough capability to be an IDE, but I don't use it like that. I use it as an editor, maybe with a language mode to do syntax highlighting and help with formatting.
I tried Visual Studio years ago, didn't care for it.
