> That awkward phase of internalizing that '=' is an assignment operator and is different from another operator meant to test equality gets a lot shorter for a beginner.

Pity language designers don't take the more obvious solution of making their maths-derived operators behave like the language they're drawn from.
It could be due to hormone imbalance, have you checked your thyroid and testosterone levels?
In 1999, an accquaintace of mine had his Internet company bought out for $1 million in cash and $19 million in stock of the buying company with a 2-year vesting period. One year later he was given the option to cash out his stock early, but given the momentum of the stock market at the time (he now had nearly $30 million in stock) he elected not to cash out.

A few months later the tech stock market crashed.

He lost his wealth, his job, his wife, the house and the cat.

"PowerShell is like a little set of APIs you can use to get at data - nothing outside of that, play within the rules "

Bullshit. It's engineering rule that all Microsoft products have all the admin capabilities exposed via powershell.

Most admin gui's are now simply a call to a powershell command.

You can pipe, and redirect input/output just like unix shells.
Yeah, I don't think that Google is even interested in buying that domain.

Exactly.

I find it funny how the biggest proponents of regulation are also those who oppose big companies as well

Because regulations are a very nice way of eliminating the (smaller) competition

Saudi is not like other Middle Eastern countries. Taxis may exist, but the limitations placed on women are far more extreme in Saudi. The rest of the Middle East are varying levels of liberal around women, with the UAE not having any legal restrictions on them, Oman having only social regulations (somewhat strict, but only for natives) on women's outfit and segregation from men in public, etc.

Availability of taxis is less of the issue here.
Ask HN: Could secure offline transactions be possible?
Offline transactions are available on many of our system : machine distributor card, local transport card, Visa/Mastercard payments.

On the firsts case (machine distributor), the amount/credit is saved inside the card without a global synchronization mechanism; so an attacker could read/change the card, generate new money and put them in the network. (http://esec-pentest.sogeti.com/post/playing-with-nfc-for-fun-and-coffee)

On the second one (cardlocal transport card), Tthe balance isn't stored centrally on oyster cards - rather changes are uploaded to the central system IF you have registered it, at the end of the day. (https://www.reddit.com/r/london/comments/2dmasr/has_there_ever_been_a_case_of_someone_hacking/)

On the last case (Visa/Mastercard), the operation should be saved on the card and on the reader POS devices (POS). Most of the Credit Card Processors (like Square) accept transactions while in Offline Mode will be processed when you regain internet connectivity within 72 hours.
( https://squareup.com/help/us/en/article/5095-process-payments-with-offline-mode )

Is it possible build some extra features for offline system to increase the security? (ok.. cryptology is a suggestion but not a solution)
PS: on the other hand, bitcoin network is completely distributed and totally synchronized by nature.
How much savings did you have accumulated one year after graduating? It doesn't seem surprising to me that stock grants are a significant part of it, though I can't say I have experience working for a large tech company.
Some of the unevenness is for occasionally non-obvious, but valid reasons. It's done in RoHS, too, for instance: lead is banned out of solder, but still allowed for some equipment, such as radiation shields for imaging machines.

The reason being that lead-free solder can still be used effectively. Lead-free radiation shields -- not so much.

The aim is to reduce the usage of hazardous substances to those cases where there's just no way around them, in the hope that it will make things like waste management easier.

Edit: CE marking requirements are also reasonably easy to work out. I know several one-man businesses that solved that problem without that much hassle, so -- anecdotally -- the minimum size imposed on a business is one :).
It's a commodity manufacturing industry. It's going to have big turnover and thin margins. There's scope for innovation-driven cost reduction, but not for SV-style "unicorns".
Thank you for understanding the choice of the language :).

In fact we (3 of us) are all working in a "big" enterprise settings so we kinda know (and suffer sometimes) about the general constraints of deploying external software (it's more probable that a java or dotNet app will be accepted than something built with an exotic stack that require others additional software that nobody is able to operate internally).

Anyway, for running lavagna you don't need a big server, I'm running it on a small (free) 512mb of ram server from openshift _with_ a mysql instance in it! This is a 5usd/month instance at digitalocean.

>What's your business model with Lavagna?

We are developing it in our spare time (I don't work full time so I can do projects like that), so nothing concrete at the moment, we are open for any opportunity.
Not student. By "23 year old", I meant a CS grad one year out of school who has been working for a year at a large tech company. Even if the tech grad had the 2014 national average student loan debt of ~$29k for all majors (tech majors have less debt), after 1 year the student will have easily paid off the debt and saved $25k.
Ask HN: Is Twitter failing?
While being one of the first users of Twitter (my numeric ID is 11278) and followed it all along the way, today I look at the list of my un/followers and I find many that follow me just for a couple of days in order to get some visibility.

Like Henry's Tavern on 1st Avenue, Seattle, followed me and then unfollowed me. What for? I've never been in Seattle, I basically live on the other side of the globe.

And this happens constantly, people that follow looking for followers and then unfollow without any sort of shared interest or connection.

It feels like I am walking along a crowded boulevard and people try to sell me any kind of stuff along the way, most of it totally unrelated to me.

And the voices of people I was interested in fade away...

What is the Twitter promise and is it succeeding to deliver it?
I've talked about the x = x + 2 / x == 0 "problems" with a couple of people during university and it seems there's different levels of problems/irritations people have with the syntax. For me it was mostly a "shrug ok so that's that, don't see the problem" when it came to accidentally using "=" instead of "==". A couple of friends seemed to have mental blockades and often wrote code containing the typical bug of "=" instead of "==" (the hotfix of 1 == a instead of a == 1 helped some).

For me the irritating thing was x = x + 2 since it triggered my math brain which protested and simply said...well that can't be, error. So I guess I did have the exact reverse problem always seeing the assignment as an equality.
Thankfully this passes really quickly after you immerse yourself in it for a day.

Of course years later one of the first sentences from our Prolog 101 prof was "so you have been programming for a while now...let me write this down...i = i + 1...someone explain what this does...what would you suppose a (stereotyped) mathematician (that only knows math) would tell me"
Kind of made me smile.

Dell's academic-facing sales force (sales and support are their core business value) seemed to start sucking around 2007+. For enterprise IT critical boxes, I would today probably shop around IBM, HP, Cisco, Dell but for web I would go the ODM/OEM route if it were a big enough order. For test lab stuff, Unixsurplus FTW.

(Dell tried to hire me thrice because I could actually use Visio to communicate visually and detail drilling quotes (BOMs) to ferret out upselling and ensure we had supportable configurations (SANs and such). I even had the pleasure to due-diligence several of their solution presentations across the table from 6 of their SE's in Round Rock with the worst hangover of my life, and we still managed to extract maximum intel from that meeting. Dell's client reception secretaries helpfully stocked boxes-upon-boxes of Advil and Tylenol samples and a righteous Keurig binge didn't hurt either. Interestingly, Dell+Redhat had a massive champagne orgy in an adjoining room and we wondered what sort of treatment the several megabucks USD customer level receives, hopefully not just a backpack or stay at the Dell cobranded hotel.)

Disruptive Technology Weekly Roundup – Jul 31st to Aug 4th
Flexport is hiring a senior front-end engineer
I know a couple of senior managers who follow exactly what's written in the blog. Another friend did something clever. Since he believes in tech industry's indomitable rise (aka Software eating the world), he uses his stocks to trade stocks of other publicly traded companies. He buys Netflix, Facebook, and stock of other lesser known companies when he's feeling like a gambler.

He treats his stock compensation as bonus. And that has worked well for him. He has a set timeline for when he cashes out, and usually draws a lot of funds only when he's investing that to buy land or house or put that money in indexed funds...

The managers I spoke about have, by my estimates, lost 10x value on the stock grant. They sold too early, too many years back. But they are still at the company. No matter how risk averse you are, that must hurt.

Some stocks are chickens that lay golden eggs.

I wonder if there's a nice mathematical way of maximising income from this.

How to Recover Deleted WhatsApp Messages on Samsung Galaxy Phones and Tablets
Not all the purposes. Abstractions can still make the complexity more manageable. Linux kernel developers write the vast majority of their code in C but very often inspect the assembly instructions generated by the compiler. Web developers have many templating languages with macro capabilities (or sass for css), but still want the generated html to be basically readable, so they can verify the templating is doing what they want, and they can debug things.

Some people really can and do ignore things below a particular abstraction, but then there are others who must service that layer transition. And not just the original authors of it. If you have an effective web company of more than, perhaps, 30 developers, at least one of them is dealing with server connection state statistics, occasionally problematic internet routes, occasionally problematic switch configuration or hardware (even on an opaque cloud platform). Someone has to deal with it, or else stuff is kinda flaky, and no one seems to know why...
Is there anything in text format? I really cannot follow the whole video right now. I tried to follow the slides, but they do not make much sense alone.

Here are some examples of things I do not understand.

The article below the video states that "By co-locating the queries with the view code, the developer can reason about what a component is doing by looking at it in isolation" but nowhere in the tutorial treasure hunt application I see this in action. There is a single React component called App, and I fail to see where it declares its data dependencies.

Moreover, according to the article, "Each component specifies its own data dependencies declaratively", but it seems that a core concept is that of mutation, which does not sound very declarative (although I am not sure I understand what that is exactly). The code for the mutation seems to access the this.props (which I assume live on the component). This looks like a cyclic dependency between components and mutations. The mutation also access a query over something called CheckHidingSpotForTreasurePayload which seems to be defined only in schema.json, although - if I understand correctly - that json is auto-generated.

All of this leaves me confused, which is why I was asking for a more conceptual explation. In other words: given the aims expressed in the article you linked (declarative data dependencies and so on), what is the reasoning that lead to the actual design of Relay?

A good way to treat the risk:

If, instead of the stock, you had been given the equivalent cash value (at today's prices) - would you choose to invest all of it in GOOG stock?

I would use that way of thinking to determine what amount of stock I wished to hold.

You're correct about Mono being complex. It was easier to install than IoT core though. Including installing the OS first. Having a package manager like apt is a revelation coming from a Windows and Mac world.

I previously tried Mono on the Pi and it had lots of bugs related to the processor architecture. Problems with the hard float support stopped things like Datetime from working properly.

This was a while ago so I imagine it's been fixed in a recent build. It shouldn't be a problem on the newer architecture of the Pi 2 either.

I think it's better to bite the bullet and just learn Linux and Python. You can then add those skills to your CV along with Windows and C#.
i live off grid inside of a 500w/h peak footprint.
i paid around $1000 for proper German (Schutten) panels, a charge controller suitable for them, 2 110ah "solar batteries" (lead acid usual cheapo old school stuff), and a Xantrex inverter.
After nearly 1 year running a fridge, lights, computer, router, & studio monitors, I'm ready to add more battery capacity before the winter (cloudy days) and a small wind turbine.

grid-tie systems are another story and a bigger investment. (need a proper electrician to wire it etc...)

feeding ignorant "city ways" in terms of people's silly habits fed by years of cluelessness (no a hairdryer will never ever be possible, as that's 2kw right there...)
that's where the biggest expenses come in...
if you don't try to keep up with the usual clueless electrical consumption, a well organized person can begin cutting their footprint down...

for example my alleged 85w macbook pro power supply consumes less than 20w typically... my inverter says so...
The first of these links gives an overview of the risks, pointing out that it depends very much on the particular factory's safety record. I don't think normalising is even possible across so many different possibilities. All the risky chemicals can be recycled and non-CO2 emissions neutralised, but this is not always done. It also says the majority type sold is polycrystalline, so CdTe are rare. (Both cadmium and tellurium are quite nasty, but also bound in by the manufacturing process and not prone to leaking)

Eh maybe somebody can explain for me. This is surely just some aberration of using enterprise value as a metric for company health, while ignoring other important metrics, right?

Like the 'value' of the company, as described here, is partially based on market sentiment, but doesn't mean that the company is necessarily any less profitable or healthy than last year...? Surely many companies go in and out of having "zero value" just as a matter of course, in that case, given that shareprices could go down for reasons other than a decline in net profit, and cash assets could go down for reasons other than ill-health.
Samsung resumes Android 5.1.1 rollout with Stagefright fix
Regarding ExDOS (or your EyePC), would we be discussing it right now if it weren't for the creator's age? Not to discount this work, but if it had been the side project of a mid-career engineer, it would be a non-story. Not because the work is good or bad, but people simply wouldn't care.

The point being, you benefitted tremendously by your work being judged relative to your age, so it seems disingenuous for you to suggest Omar shouldn't get the same treatment.

I doubt ExDOS or EyePC will be remembered in the annals of history as engineering marvels, but that's irrelevant. They are indicators that the creator has the talent, intellect, and dedication to accomplish a lot in a very short amount of time, and they hint at great potential.

It's an interesting article, because after making assumptions about the Palestinians, she actually meets them and realises that there is plenty she doesn't understand yet.

She refers to American privilege in Ramallah, but glosses over the fact that had she been visibly identifiable as a Jew or Israeli, she would likely have been attacked.

The missing context to her observations about limits on freedom of movement is that Israelis aren't allowed into Palestinian areas because it's way to dangerous for them and that Palestinians aren't allowed free passage to Israel, because that would be way to dangerous to Israeli civilians.

For casual home cooks I'd recommend hard anodized aluminum. It's an excellent non-stick surface, easily hand washable, non-toxic, fairly durable, and low cost. Really as long as you aren't constantly gouging it with metal things then it'll hold up for years and years.

Cast iron is great too though, don't get me wrong.

I think, it is not that simple. In your case you have access to a lot more information about the company than most of investors. If you really believe in business that you are in, I think you should keep the stock. If something happened in company, you would be the first one at the door since you live and breathe the company's news.

I just sold all of my Microsoft stock two days ago and now I come across this article. Avesh is absolutely right about the points he is making and I think that everybody who are entitled to stocks as a part of their payment package should sell these immediately and construct a more balanced portfolio instead.

If you (like myself) feel like you are better at writing software than acting like a wolf on Wall Street you should take a look at index funds. An index fund is a fund that reflects the development of an index (e.g., S&P 500 or FTSE 100). Rather than paying a portfolio manager a high fee (of up to 5% of the invested portfolio) to actively manage your investments, an index fund is designed so that it simply follows an index. This is much cheaper than actively managing the portfolio. Since John Bogle came up with the idea about 40 years ago and founded The Vanguard Group, history has proven time and time again that active investors can't beat the market in the long run. Index funds therefore yield a higher net return because of their lower costs (typically around 0.5%).

If you are new to investing, I would suggest to go with the three-fund portfolio[1]. Divide your portfolio into three parts and invest in a domestic stock market index fund, an international stock market index fund and a domestic bond index fund. This would probably yield an annual return of 10-15% with a very controlled level of risk. I have constructed my portfolio like this and I am really happy about it. I don't have to constantly worry about my investments and at the same time I can expect a fairly solid rate of return.
