i did a smart contract in remix and then send funds and clicked start.
Then my balance went to 0 Ether. Is there a possibility to get it back?
Here is the video i used:
https://www.youtube.com/watch?v=GFHZUn7X52Y&
was it a scam or did i just had bad luck?
The guy made the video said it's stuck in the mempool router adress becaus ethe network was to busy and my 1 ether couldn't create enough slippage.
then he said i can solve this if i send the exact same amount again to reset the bot. (routing duplicstion) but that sounds like a scam. Maybe my money is lost, but if someone can really help me i will thank him with 0.1 ether.
here is my contract adress:
https://etherscan.io/address/0x70f8441337677BA13552E8FC3f956FFB7f078451
the code will be found in the youtube description.
best regards and thanks in advance.

Do not send any more ether to the contract, THIS IS A SCAM !
Sorry to break it to you but this looks like another uniswap bot contract scam .. just by looking at the video, the crazy amounts he's claiming to return, and comments on the video you can definitly say that something fishy is going on.. I got the owner's telegram handler from his youtube and I pretended that I had a smiliar issue as yours and I got the same answer, he wanted me to send more eth, so here is that.
Scams of these genres are very popular and everyone should be aware of! the contract you deployed imports another one from the IPFS that allows the scammer to steal your funds once you deposit them into this UniSwap contract and there's no way to get it back.

When getting conv.user.last.seen, I get a value from Google Assistant on Pixel and from Google Home, but Lenovo Smart Display returns undefined.
A Pixel is a personal device and the user storage is all the time available there. A Smart Display and also speakers are shared devices. The user storage only works if the Personal Results setting inside the Assistant App for that device are turned on.
Important: You never know if you are able to persist data in an Action on Google. You can write data to conv.user.foo but never know if it is there if you invoke the action again. So it's important to make sure that the dialogs are well designed even when you were not able to persist data for returning users.
Update 2019-06-28
Google released a new flag (yeaah) to handle this. The flag is called verification. You can find the documentation here.

From what I understand, you have to enter in all of your usernames and passwords into Mint, so I assume they are actually logging into your bank account and scraping the resulting screen to put this data into a form that Mint and others use.
How do they actually simulate the keypresses and mouse clicks? I assume banks don't like it when they do this - how do their scrapers avoid detection?
I'm pretty sure they don't simulate clicks, etc. In the end, any data that ends up on a user's page is transmitted in a response to a request. If you can figure out how to construct a valid request and then how to parse the response, you'll have the data you want.
As far as I could gather after using Yodlee for quite a while, they deal with sites in two major ways: the sites they have official agreements to work with and the sites they don't have official agreements with. For the first category of sites they, most often, have agreed upon APIs for getting the data. For the sites in the second category they reverse-engineer layer 7 communication protocols and data structures (a.k.a. screen/html scraping).
The way I understand it, Yodlee uses the OFX specification to access banks' financial information.
http://www.ofx.net/
For the banks that don't implement OFX, they use custom screen scrapers, which must constantly be updated when banks change the information that's displayed on their site.
I don't know Yodlee so i simply assume it's like "sofortüberweisung.de" where you give a 3rd party your bank login data (and depending on what you do even a valid TAN) and thus trust them not to abuse it and additionally break your bank's security regulations ("NEVER GIVE YOUR YOUR PIN/TAN").
They most likely simulate what a browser would do. As web-based banking interfaces are usually just HTML/JavaScript everyone can look at the client-side code and do whatever it does with a custom program. Since those actions are not done in a malicious way, actions which require e.g. a TAN or a CAPTCHA to be solved can be simply forwarded to the legit user who will then enter the necessary TAN or solve the CAPTCHA.
Nonetheless to say, it is really bad to use services like that. While they most likely won't do anything bad you cannot know it for sure. And your bank is damn right if they don't refund you anything if you ever get scammed by such a service.
Another solution which would be perfectly safe (as long as you are not concerned about a 3rd party knowing about your financial status etc.) would be the yodlee company making contracts with major banks allowing them to access your data after you've authorized it through some way (you can already do that on pages like Twitter - I'd never do that for bankign though but technically it wouldn't be hard to realize something like that). That would be clean and secure as it would not involve "screen-scraping" or customers entering their banking login data anywhere but on their bank's website. But I believe no bank does something like that and in my opinion that's good as there are way too many people out there who are far too trustworthy and we all know how many information they give out on Facebook & Co. Now imagine a facebook<->bank integration... M.Zuck.'s wet dreams which hopefully never become true... And even if it's not Facebook.. There'll always be companies who want people's personal data and enough people giving them out; especially if it's easy and looks secure ("I have to confirm it on MY BANK's page. so it MUST be safe - it's supported by MY BANK").

I'm in the process of opening up a company that will eventually hire 2-5 developers to work on a large web app.
My main concern is that one or more developers could steal the code. I could make them sign contracts against this type of thing, but I live in a country where the law is "bendable".
Is my only option to lock them up in a room without inet access and usb ports?
I'd love to know how others have solved this problem.
Don't hire people you can't trust.
Break the app into sections and only let people work on a subset of the app, never getting access to the whole thing.
Make it worth their while - you're opening a company, hire people and give them some stock options. Make sure it's more attractive for them to make you succeed than otherwise.
How about keeping them all happy and show that you appreciate their work?
You may find that you think your source code is the valuable part of your business, but you can always build that again. Your real advantage over your competitors is usually in the people you hire, and in the business relationships that you establish in the course of naturally doing business.
My suggestion is not technical but social: Make them feel good.
Most human beings have a moral base that prevents them from hurting other people who have treated them with respect and generosity.
There's a slim chance you'll wind up hiring a psychopath, in which case this approach won't work -- but then, it's likely to be the least of your worries.
The only thing that occures to me is to make them sign a contract where you explicit that if they share any code outside the project ambient, they'll compromise to pay you a large amount of money. But there's no guarantee they'll not do it anyway ..
You can create a vitual environment (a virtual machine) with limited internet connection (only to specific servers - git/svn server, database server, etc) and no copy/paste possibilities.
This virtual machine would be a standard environment with common developer tools.
At the office a developer would remotely connect to the virtual machine and start developing without being able to steal the code.
Of course he could print the screen or type the code on another computer but it's still very hard to steal.
There are many encrypting softwares available to encrypt the code. Here is an example http://www.codeeclipse.com/step1.php
In other words you can hide the code of one developer(one module) from the other developer and he will not be able to take the whole code himself in any case if you follow this approach.
Thanks

I'm a full time software developer, but on the side I'm teaching a university course on web services. I'm going over security right now and was wondering if any of you all have had any security breaches that you could tell about (details obscured as needed) that I could share with my students. Real life stories are a lot more meaningful than made up scenarios...
Here is a story from me:
I once was customer of an online audiobook store. Beside authenticating myself with username and password, I also needed my browser to accept cookies. This wasn’t unusual. The cookie is probably needed for storing the session ID.
But I got confused since the session ID was also transmitted in the URL and I didn’t saw a reason for why there was a need for cookies. So I took a look into my cookie jar to see what oh so important information have to be stored in cookies.
Beside a cookie for the session ID there was another cookie named customer_id that obviously was designated to identify me by my customer number. I thought: “Come on, no one can be this stupid!” I altered the value for fun by changing one digit of the number (e.g. from 12345 to 12346) to see what happens.
Now guess what: I now was logged in as a different user without any further request for authentication just by changing the cookie! The customer_id cookie value was abviously not just for identification (Who am I?) but also for authentication (Am I really the one who I pretend to be?)!
The moral of this story: Always separate identification from authentication.
This may not be what you had in mind, as there was no information compromised, but it still very much a web security issue.
http://www.crime-research.org/library/grcdos.pdf
That is the classic story of how internet security guru, Steve Gibson's, site was attacked by a botnet. It is a very interesting story and would certainly keep the class engaged. I know this story got me more interested in web security.
I could not find the original post of that pdf on Steve Gibson's site (grc.com), but I had a copy on my computer and was able to search for it and found it at the given location.
I also recommend going to grc.com and listening to the "Security Now!" podcasts:
http://www.grc.com/securitynow.htm
You will almost surely hear some stories in some of those podcasts.
Hope this helps!

What's the best way to close the loop and have a desktop app "call home" with customer feedback? Right now our code will login to our SMTP server and send me some email.
The site GetSatisfaction has been an increasingly popular way to get customer feedback.
http://getsatisfaction.com/
GetSatisfaction is a community based site that builds a community around your application. Users can post questions, comments, and feedback about and application and get answers to their questions either from other members or from members of the development team themselves.
They also have an API so you can incorporate GetSatifaction into your app, and/or your site.
I've been playing with it for a couple of weeks and it is pretty cool. Kind of like stackoverflow, but for customer feedback.
Feedback from users and programmers simply is one of the most important points of development in my opinion. The whole web2.0 - beta - concept more or less is build around this concept and therefore there should be absolutely no pain involved whatsoever for the user. What does it have to do with your question? I think quite a bit. If you provide a feedback option, make it visible in your application, but don't annoy the user (like MS sometimes does with there feedback thingy on there website above all elements!!). Place it somewhere directly! visible, but discreet. What about a separate menu entry? Some leftover space in the statusbar? Put it there so it is accessible all the time. Why? People really liking your product or who are REALLY annoyed about something will probably find your feedback option in any case, but you will miss the small things. Imagine a user unsure about the value of his input "should I really write him?". This one will probably will not make the afford in searching and in the end these small things make a really outstanding product, don't they? OK, the user found your feedback form, but how should it look and what's next? Keep it simple and don't ask him dozens questions and provoke him with check- and radioboxes. Give him two input fields, one for a title and one for a long description. Not more and not less. Maybe a small text shortly giving him some info what might be useful (OS, program version etc., maybe his email), but leave all this up to him. How to get the message to you and how to show the user that his input counts? In most cases this is simple. Like levand suggested use http and post the comment on a private area on your site and provide a link to his input. After revisiting his input, make it public and accessible for all (if possible). There he can see your response and that you really care etc.. Why not use the mail approach? What about a firewall preventing him to access your site? Duo to spam in quite some modern routers these ports are by default closed and you certainly will not get any response from workers in bigger companies, however port 80 or 443 is often open... (maybe you should check, if the current browser have a proxy installed and use this one..). Although I haven't used GetSatisfaction yet, I somewhat disagree with Nick Hadded, because you don't want third parties to have access to possible private and confidential data. Additionally you want "one face to the customer" and don't want to open up your customers base to someone else. There is SOO much more to tell, but I don't want to get banned for tattling .. haha! THX for caring about the user! :)
You might be interested in UseResponse, open-source (yet not free) hosted customer feedback / idea gathering solution that will be released in December, 2001.
It should run on majority of PHP hosting environments (including shared ones) and according to it's authors it's absorbed only the best features of it's competitors (mentioned in other answers) while will have little-to-none flaws of these.
You could also have the application send a POST http request directly to a URL on your server.
What my friend we are forgetting here is that, does having a mere form on your website enough to convince the users how much effort a Company puts in to act on that precious feedback.
A users' note to a company is a true image about the product or service that they offer. In Web 2.0 culture, people feel proud of being part of continuous development strategy always preached by almost all companies nowadays.
A community engagement platform is the need of the hour & an entry point on ur website that gains enuf traction from visitors to start talking what they feel will leave no stone unturned in getting those precious feedback. Thats where products like GetSatisfaction, UserRules or Zendesk comes in.
A company's active community that involves unimagined ideas, unresolved issues and ofcourse testimonials conveys the better development strategy of the product or service they offer.
Personally, I would also POST the information. However, I would send it to a PHP script that would then insert it into a mySQL database. This way, your data can be pre-sorted and pre-categorized for analysis later. It also gives you the potential to track multiple entries by single users.
