`throw` in Java's exception handling also prematurely exits a function. So?

While `try!()` is a macro and not a core language feature, most of the macros in the standard library can be treated as such. So a Rust programmer will know that `try!()` can return, just like a Java programmer knows that `throw` returns early.

Besides, macros are syntactically distinguishable in Rust. When you see that exclamation mark, you have to rememeber that it's a macro and might be doing arbitrary compile time things along with arbitrary token tree expansion.

Not exactly. Git uses per-file, per-commit, and per-directory hashes. It does make up a sort of hash tree, but the tree does not descend within a given file. You need to hash the entire file and determine its hash to know if any of the pieces you have are valid. This would be a problem for large files if many of those pieces come from untrusted sources -- you'd have to spend a lot of time/bandwidth downloading invalid data before you realized it. This isn't generally the case for Git, but it for BitTorrent.

BitTorrent traditionally solves this using a hash list. All of the data in a torrent is broken up between pieces of a chosen size, and hashes are calculated for each of those pieces individually. (These are generally not aligned with file boundaries, which is why you may have noticed that even if you tell your torrent to only download a certain set of files, you may still end up with some data from adjacent files.)

This entirely hash list is included in the torrent file. For torrents with a lot of data, this could be 10MB or more.

If you're using a magnet link, that torrent file needs to be downloaded from peers. This brings back the original problem: you need to download this entire large file before you know that the peer isn't just sending you random data.

BEP-30 proposes a solution: generate a binary hash tree whose leaves are the torrent pieces, and include only the single root hash in the torrent file to keep it small. When you're getting pieces from a peer, they send you the missing inner hashes of the tree that you need to verify the piece.

The minimum data transfer in ideal circumstances is increased a bit, but the peer-to-peer system is made more robust, able to identify invalid data much faster.

I think it's a great modification to the protocol. Unfortunately it isn't widely-enough supported to be practical for general use.
It's just too bad the speed of light is what it is. A few orders of magnitude higher and we've have a galaxy to explore. A few orders lower and we've have fun relativistic effects in daily life.
If these can be triggered so far in advance of a quake, couldn't we bury instruments of some kind that also trigger under those conditions? That would be useful regardless what types of rocks are in the area.

And the corollary to that: space is empty, really really empty. The government could encourage space exodus, even offer each citizen $1 million to leave. It's still just not possible right now.
A few notes:

1. Average and amortized have very different meanings in algorithmic analysis.

2. One mistake - Okasaki's queues in "Simple and Efficient Purely Functional Queues and Deques" are actually constant-time in the worst-case.

3. Okasaki makes a strong case in his book that the kind of analysis that rejects amortization over ephemeral usage when a structure can be used in a persistent setting is not "more egregious than describing quicksort as O(n^2)". Note, for instance, that quicksort is O(n log n) with high probability with good randomness, and O(n log n) in the worst case with median-of-medians. This quadratic queue case may be degenerate, but the degenerate algorithmic complexity attack of turning hash tables into linked lists by manufacturing collisions is well-documented and worth worrying about. I claim the same is true of queues if a persistent interface is exposed to the user.
"Large torrent files put a strain on the Web servers distributing them".

Finally! bittorrent designers are acknowledging the centralized deficiency in the torrent protocol and implementing Merkle / root hash distribution model, as eDonkey / eMule used since 2000's:

> we have every reason to believe there’s plenty more, and perhaps even infinitely more [Universe out there beyond the portion that’s accessible to us]

Which order of infinity do you mean when you say "infinitely more [space]" here? Aleph-One?

> we can extrapolate the Big Bang backwards to an arbitrarily hot, dense, expanding state, and what we find is that it didn’t get infinitely hot and dense early on

And what order of infinity here for the energy?

> the Universe was filled with energy inherent to space itself: a state that causes the Universe to expand at an exponential rate

If the infinity used to measure 2 different entities are of different orders, then there'd be at least an exponential differential between those entities. But what if the order of infinities is switched around between energy and space, could that then mean there's only one instance of inflated space in existence?

I've never read a discussion of multiverses, whether wrt inflation or quantum mechanics, where the order of infinity used is mentioned. Specifying what order of infinity is to be used for each measurement seems to be crucial to what result is infered.

Scry Analytics – Raleigh, NC

Senior ETL Developer (Pentaho/Talend)

We are in urgent need of a senior ETL developer professional with some or all of the following skills and background (7-9 years of ETL experience):

* Pentaho and Talend experts on a full-time basis; for most situations we are using Pentaho suite and Talend-DI.

* Applicants must have a development background with enterprise Databases like SQLServer and Oracle (or preferably PostgreSQL) and their respective scripting platforms.

* Applicants must have a development background with high-performance ETL tuning and a reasonable amount of experience in core Java development.

* Applicants should eventually be good teammates within Scry Analytics and good at working directly with our enterprise customers.

* We have these openings in our San Jose and in our Raleigh offices (in the United States) and we are looking to hire at the associate level, and at the mid-manager levels.

* Domain knowledge of networking technologies and operations will be good to have; in any case, the candidate should be open to learn the skills on the job.

* Working knowledge of parallel computing, structured and unstructured databases, machine learning and artificial intelligence is definitely a plus (but not a pre-requisite)

* Scripting skills on Linux is a must.

The English word, "Scry" means "crystal ball gazing".
Scry Analytics (www.scryanalytics.com) provides Big Data Science solutions to do predictive and prescriptive analytics (i.e., to "forecast the future") and our aim is to:

* Codify work-flows in the services industries so that they are well-defined & repeatable.

* Collate and harmonize client's data that is required for such work-flow systems.

* Provide Scry Analytics' proprietary data that improves the key performance indicators and the characteristics of such work-flow systems.

* Use our proprietary Big Data Science platform as well as deep Computer Science & Math algorithms to build decision support systems that improve the metrics related to these work-flows.

Although Scry Analytics provides analytics and Big Data Science services, our aim is to minimize these services by providing automation and software solutions (where we can). We are currently solving problems in the following domains:

* Retail

* Banking and Insurance

* Inventory & Transportation of After Market Parts; Maintenance

* Utilities and Telecom

* Health care

Since most techniques that Scry Analytics is using are taken from cutting-edge research, the kind of solutions that we are building are unlikely to be built by companies that provide data analysts in a staff augmentation mode or those that provide IT professionals. So, we are looking for Bachelors, Masters, and PhDs in computer science, data analytics or math that have a "research" or "advanced development" bent.﻿

Anyone who has taken a JD Jackson based course has derived this result. Special relativity is a fairly obvious consequence of E&M in hindsight.

FWIIW, this is a terrible proof with bad notation (you don't need to write out the matrix), which doesn't actually prove the interesting piece, which is the fact that the permittivity of free space is the same no matter what your frame of reference is.
Said a different way, if you believe in the fine-tuned universe theory, then the multiverse theory would by definition predict our own outcome. It doesn't make either true, rather one of many puzzle pieces that happen to fit together. In 200 years, we may have proof of gravitational waves (or have found none) and many other interesting puzzle pieces that will continue to drive the thinking within quantum mechanics and string theory. Some believe the entire branch of string theory to be philosophy -- though I think this is limited by the belief that because we can't test many of these theories today that we will never find a way to test them in the future.
Yes they do.

This would benefit who exactly?
Have you, or someone else, got a source for this or articles/studies done?

Not questioning it, just curious.
I'm sick of people like you. You really do not know anything about the socio-political situation on Brazil nor Croatia to state that.

Probably you are just a high class "worker" that compose the high income "class" which only say and trust their peers, wihtout seeking to know this huge country of ours.

You probably do not go to the city hall to get a say about the year's budget planning nor associate with peers to increase the power of representation, nor call or email your congress member to vote to which law you think will improve the situation.

Please do not be a teenager that think that everything is wrong and compare with Croatia that have a HDI avg "very high", a country that got it's independancy in 1991 and still have a better quality of live than us.

Please state your facts before comparing Brazil with a completly distinct scenario.

Edit: Please! your about.me says that you live in "Amsterdam, Netherlands". Get back here! do not run away. Help us get this great country better rather than escape and live "bettter" in another country, helping their economy.
I'm also interested in an answer to this question. Perl 6, as a feature set, looks awesome and I'd really consider replacing my use of Python with it, espcially because of the gradual typing and fast startup time (assuming Perl 6 follows Perl 5 in this regard; my initial experiments haven't been encouraging though).

In general, I think there's huge latent demand for a relatively fast, "next-gen" scripting language, as even Python is showing its age in terms of the programming styles it doesn't support, and has no plans to.

Will it really be released by the end of this year? Obviously the history of this project induces a healthy bit of skepticism. My two cents would be that the dev team should just release it next week and fix the inevitable warts gradually.

On a related note, should I, as someone who does not know Perl, bother learning Perl 6 yet? Or is it likely to change a lot before release?
> These impossible combinations are discarded. For example, the bear said he saw a fox. Therefor [sic] it is not possible for the bear to be truthful and the thief to be a raccoon.

Per the story, there is a 20% chance a truthful bear may have mistaken a raccoon for a fox. Not automatically discarding possibilities like "a truthful bear saw a fox, though the thief is a raccoon" is a hallmark of probabilistic thinking. Thinking through these examples formally has advantages over starting with code.
Welocalize | Los Angeles, CA (Santa Monica) | Lead Developer

We help Google, Harley Davidson, PayPal, Expedia, John Deere, Blackboard, Marriott, Cisco, and many more demanding brands get to market around the world by providing a global localization workforce.

----------------------------------------

About the project

----------------------------------------

We already have an automated supply chain and internal project and accounting systems. we now want to build:

- predictive models to estimate the output quality and delivery date of a task, at every stage of execution

- a work assignment system to decide which worker in our pool should be assigned each incoming task

- tools that use NLP, machine learning, and signal analysis to analyze incoming content and improve the signal for our predictions

- web applications(s) to help our supply chain management team better analyze the worker pool, run training campaigns, discover at-risk tasks earlier, and generally benefit from the smart stuff we're doing

We're starting a new team in Santa Monica to focus on this. Starting with two developers and a data scientist (plus some extra support), we'll build an MVP and pilot it in production with some of our largest clients.

----------------------------------------

Who we're looking for

----------------------------------------

Looking for an experienced senior developer who has built complex production web applications.

Skills needed:
- Able to take the lead on making design decisions, setting standards in a team, and resolving issues

- Able to learn new programming languages

- Able to assess the merits of frameworks and 3rd party systems

- Basic knowledge of html / css / javascript (e.g. to build simple admin screens)

- Know enough linux and AWS to set up servers and clusters

- Willing to help steer the product direction

Nice to have:

- knowledge of Rails or Django (so we can reference the design of these frameworks when discussing how to set things up)

----------------------------------------

What we offer

----------------------------------------

This is a chance to build systems from scratch in whatever technologies we choose, while gaining data science and machine learning chops.

We are a stable, profitable company, and will not be asking for death marches.

We have 401k match, health insurance, and other typical benefits. The environment will be flexible and informal.

----------------------------------------

Tech stack

----------------------------------------

I'm thinking we should consider using python as our main backend language, since many of the toolkits on the data science side use it. But we're going to have a heterogeneous environment regardless. I'd be fine with using Go, Scala, Rust, Elixir, or some other hot language for some of our stack if it helps interest the right person.

If you have any interest in this, please email me directly: doug.knoll@welocalize.com
Ionic vs. Native JS
I don't think you know what the word "political" means. You can't just use it as a term for people who uncritically spew whatever bullshit they were fed out their mouth hole.
How much do you think a bank would have lent to someone with anyway a fair chance of not paying it back?
The article doesn't seem to mention this at all, but Latin definitely lives: it's called modern day Romanian. There are many differences but if Latin survived anywhere into modern times it would have to be Romania. I had some Latin in high school and that came in surprisingly handy, much more so than in other Latin derived languages.
Stolen right off of LowEndTalk.
The current batch of government sponsored technology seems different to me. With radar and transistor technology they were doing something that was fundamental (perhaps some hindsight bias here, but that's my opinion anyway). The new technologies are just putting together existing technologies. The fundamental research is things like the work on neural networks being done at Google, Baidu etc.
What do you recommend, then?
But does it work with near-zero inflation or deflation?
Thanks. So the main benefits are from simply enumerating sub tasks, assigning best/likely/worst case values, and repeating the exercise to improve sub task coverage. It sounds like the actual statistical analysis is only an incremental improvement beyond that, and probably does not add significant value to small projects.
> Well, there's this crazy concept called "saving money" where you don't borrow from a bank but rather put some money aside every month to be able to afford something expensive

That's great, except that everyone is born short housing. You're not trying to afford something expensive, you are trying to cover your short position. And you're either going to do it by buying or renting. And since renting is just throwing the money at someone else, it can make a lot of sense to get into a mortgage instead. (This is why rent vs buy calculators exist.)

> I wonder what would happen to property prices if lending was severely restricted, maybe then the value would actually be affordable and not a lifelong debt that becomes unserviceable in the first hiccup

Agree on this point. It's a lot like universities and student loans. They have the numbers; they know the average student can afford $x / semester. They also know the average student can take out $y / semester in loans. So what are they going to charge? $(x + y)! Increasing the accessibility of student loans just gives the universities a reason to increase the prices. They don't care how much debt students walk out with; they already got theirs.
Not sure why you're downvoted. Its true. And as ride shares like Uber take off, car ownership will continue to decline. Self-driving cars? Even more so.
This stuff does happen in the US at least. I've only heard stories, but always from the "technically guilty" (e.g. the guys that destroyed/burned things down as retribution). One thing that's consistent in the stories I've heard is that the crooks always failed to carry insurance. Their "cheap" nature extended even to protection policies on their own ill-gotten gains.

We're an advertising agency that has helped take our clients app to #1 grossing for education with an ROI positive budget.We've done some awesome work for other tech companies as well. We're less traditional than most agencies. Think less 6 month marketing plan and more rapid deployment and iteration. If you like the idea of an outsourced marketing team that uses scrum modified for marketing instead of software, we're probably a good fit.

"You get a percentage of the gross or you are not taken seriously."

Correct, but you also have to be taken seriously to get a percentage of the gross. Not everybody who asks for gross points gets them. Generally speaking, you need to be on the A list, or have a killer agent, or have a property that incites a bidding war between studios.
For all we know the NSA may have made some interesting advances in computing or mathematics, and the CIA have probably advanced optics and image processing by a few generations. Unfortunately for us, neither of them are sharing.

I wish bundling Python was easier. I read this morning in the Kivy docs that you can't even bundle python 3 at all yet.

Many years ago a friend of mine wrote a Python binding to the PopCap engine. It was so great, the exe and the script. Thats all you needed and you could just whack those two things in a zip and you're done.
To me it seems the article is completely mixing up two multiverse theories - one is that there are several essentially completely independent universes separated in space (or time) and the other is that there is no collapse of the wave function but all the possibilities encoded in the wave function are actually real and therefore many universes are kind of overlaid at the same time in the same space and in each universe you observe the wave function collapsed to a different state. Did I get it wrong or the article?
I earned a pretty good living for 10 years taking data in form A and turning it into form B. It still amazes me with all the programming and reporting tools that this is still a thing.

On languages, I wonder if language designers would in addition to a standard library provide a standard set of templates for common needs (e.g. representing a person). It would save a lot of the plumbing time to get a template that has had some thought and best practices added.
