There are mechanisms by which a landlord can raise a rent inside the bounds of a lease. In my experience, multi-year leases have "elevator clauses" that either allow for pre-negotiated upwards adjustments in price based on property tax, CPI, or other measures.
Whenever I need to ask someone a question about something, I take 2 minutes to do just one more bit of homework on the topic.
The goal to give my brain one more shot at figuring it out on its own. Either I figure it out and I don't have to ask anyone else, or I'm now more informed about the topic when I ask someone a question, and I've moved the topic back to the top of my memory.
When it works, I've learned something, saved someone else from being interrupted, and I get a little kick of "I did it all by myself!" satisfaction. Even when the trick doesn't work, the ensuing conversations are usually much more productive.
Of course, I wanted to believe it was true. Unappreciated worker with morally-lite boss in a despised industry. What's not to like?
The lighting was too good though. Specifically, it looked like there was a tripod, a well-calibrated fill-flash and an additional, off-center light source.
Clearly, not impossible for a person and a timer to do, but it began to hit the limits of plausibility.
If you don't understand why people are complaining, you may want to take a moment to understand why.
You have shown how to block it, but there is a larger discussion of why or why not it's bad, how it breaks copy/paste, attribution problems, and so on. You might do well to look outside the narrow technical bounds of fixing a specific technical problem to think about the greater issue.
To answer your specific question, it isn't necessary. It's just another Turing-Complete language, right?
Perl was one of the first popular scripting languages out there to have well-integrated regex handling and was useful for programming purposes. Most old-school systems and network people not only know how to code their way out of a paper bag, but typically grew up with C and Perl as their two go-to languages. C when you needed speed above all else, and Perl when you needed the regex functionality.
While specific functions vary for any given environment, I can safely say that I've written all of these in Perl at one point or another:
- Crunching netflow data to make life easier for those who do capacity planning.
- Running glue scripts against a device database to generate the configs that go to open-source monitoring systems.
- Lexing SNMP data in order to generate a device-independent network configuration, and then turning around and "compiling" it to another target network device.
All of these could be re-written in python. I've done it. Yet, they're all written in Perl because that's what the people who "Run The Internet" historically have used.
In another generation, maybe Python will be the regex-heavy scripting language of choice. For right now though, I suppose the best answer is that that Perl holds the Internet together for historical reasons, because that's what got the job done.
At the risk of self-promotion, a while back I did a presentation on naming schemes for network devices, which have slightly different requirements than servers:
To use a recent movie quote: "If you can dodge a wrench, you can dodge a ball."
ITA's business is all about dealing with fiendishly clever transforms on small-ish sets of data, and the results are needed Right Now. Most of the hiring puzzles revolve around that theme.
Much like any other company giving these kinds of problems, it's not about bringing out that cleverness every day, but it's about figuring out who has the ability to think in that way, along with the persistence to work on the problem until it's done.
At a guess, they're trying to make it up in volume.
If you're a merchant bank, the smallest thing you can profitably target is a small business, so even a handful of significant bad accounts will do bad things to your bottom line.
Assuming that the potential customers of this service are not trying to commit fraud, and that each one of those customers is doing a relatively low amount of transactions, Square could put this device in the hands of enough people that the aggregate chargeback percentage would still be low enough to be profitable.
I'm just glad that the court explicitly said that "nonpracticing patent owners" are distinct from those who would benefit from the use of the patent in manufacturing.
Stating that “we observe that Acceleron is solely a licensing entity, and without enforcement it receives no benefits from its patents.[...]" is a very interesting retort to the standard argument for IP holding companies, that being "A patent is a patent, and it doesn't matter whether the owner is going to use it to produce an item or not."
I'm reminded of the Latin phrase "Age quod agis", literally "Do what you are doing."
It has been my experience that half-hearted attempts to learn/do things end up taking twice the effort of making an honest attempt and getting real results.
