Is it possible to hack into a school's grading system
I just want to let everyone know about this good Samaritan....blackhatlord (at) protonmail (dot) com who is ready that smile back to the face of those that's in need of making a better way out of their mess, he's good at various kind of hacking services all it take is just one email to get that smile back on your face. Surely you'll love to work with this guy.
oooh .... sadly I haven't had access to kernel source for maybe 30 years, it's been a long time essentially you need to write a BSD style networking driver (of the era, so likely 4.1) along with interrupts/etc I think without source it's going to be really difficult - on the other hand you can use autoconfig to load it into an old kernel, hook up the interrupts and set it running

A Roadmap for Exceptional Access Research
I don't understand why people don't use Firefox for Android. It's easily the best mobile browser: allows addons (like uBlock Origin) and connects with the desktop browser (share tabs etc).
Would clearing cookies and cache work?

On Chrome, theres an option to list cookies for a site by clicking on that padlock to left of site url, so quicker way of clearing cookies for your Jenkins site. Maybe FF has similar setup.

Then hard refresh browser should clear cache I think (ctr/cmd + shift + r on any system or ctr + f5 on windows).
Even so there's good, better, best on a spectrum, right? :)

Or is my '80% renewable' point naive? I think i get what you're saying, if I recharge during peak demand times, there's a chance nonrenewables are being used in higher proportions to fulfil my charge. Conversely if I charge during low-demand hours, the odds are higher that peak generation methods are not being employed.

But even more complicated than that, is the kind of renewables. NZ has a ton of hydro, and during certain times of the year they are drawn down for peak demand, so kinda ideal. Then again during times of drought, no can do and non-renewables may be the only thing that can meet demand.

If you're getting super fancy, NZ Transpower publishes live stats for the grid, including proportion of renewables in use at any one time! https://www.transpower.co.nz/power-system-live-data
unfortunately its hard to be like "ok i hate this mattress so much I will sleep on the floor until I find something I like better. take it back!"
For the first thing, you're talking about "keyword search" (as ever, knowing the right term to use when you're searching makes all the difference, and good luck if you don't know the right term)

It's present in Firefox and has been for several years now. I use it extensively both with internal and external sites, e.g. I type "people joe blogs" in to my browser and it opens up our internal phone directory and searches for the person.

It's super simple to set up:

Go to the desired site. Right click on the search field, and choose "Add a Keyword for this search". Pick a name for the bookmark, and then pick a keyword to go with it.

That's it, job done :)

The two issues in America are not in practice totally separable. The relationship is not purely correlative. It's pretty clear in America that white people don't like to see some races "getting above their station" by climbing the class ladder. A pretty clear example are the Tulsa race riots: https://en.wikipedia.org/wiki/Tulsa_race_riot

Greenwood was a prosperous black area near Tulsa, doing so well that it was known as "Black Wall Street". White resentment eventually boiled over and 35 blocks were burned to the ground. Hundreds were killed, and it included many horrors, including white people using then-new airplanes to firebomb the neighborhood from above.

If you read Loewen's "Sundown Towns" you can find plenty more incidents where white resentment of black success led to oppression, violence, and sometimes death.
> Well it happened in the solar module market[1].

What is "it" that happened? If you are talking about sustained exponential cost reductions over a period of decades, like Moore's law, then maybe it did happen from a very high starting cost, but it won't continue.

Any market can undergo a rapid reduction in prices over a short period of time, as a product increases in adoption by one or more orders of magnitude.

You could fit an exponential curve to that growth, but ... it will almost never be sustained. The future is what we are talking about here.

Let's take solar modules as an example. From something like [1] prices have dropped from about $4.00/watt to $0.30/watt in 10 years. So that's a price drop of about 23% per year (each year is 0.77 the price of the previous). So today, at 30 cents/watt a 300W panel (the big ones you see on houses) is about $90.

If that is really a sustained exponential drop, those same panels will be $6.75 in 10 years. Possible? Yes. That said, I don't think you can find almost anything that big and heavy almost anywhere for $6.75. Maybe bricks or gravel or something, I'm not sure.

10 years later, those same panels will cost 50 cents. Possible? No way. You aren't going to ship a 300W panel anywhere for 50 cents. You aren't going to have space in your warehouse for something that big for 50 cents. You aren't going to be able to buy even the basic raw materials like glass and aluminum for 50 cents.

There's a common theme here: for something to scale exponentially, at a fixed size, every part of the process has to scale exponentially. The cost of shipping was irrelevant when the panels were $1,000, but it becomes pretty important when you are trying to ship something that weighs 100 lbs across the world or even a country and sell it for less than a dollar. The basic raw materials are a pittance with $500 panels, but they dominate the cost if you are trying to sell them for 50 cents.

The only way this exponential scaling works is if you can make something roughly the same size exponentially more efficient. That's that happened with CPUs. The CPU itself was more or less the same size for decades. They made them in similar fabs. There were some "traditional" efficiencies of scales thrown in, like moving from 200mm wafers to 300mm wafers, but the only thing that allowed exponential improvement was that the chips themselves became a million times more efficient without increasing in size or (mostly) the consumption of any raw material.

CPUs didn't scale up a million times by building a giant fab the size of a country, and using wafers miles across and mining silicon from the moon, which would be how a traditional process would scale up: they scaled up by becoming internally a million times more efficient.

Solar cells don't have that type of scaling available to them. There are hard limits on the efficiency (which is already above 20%) based on the physics involved - but even without any reference to cell physics there is a hard limit at 100% which means the efficiency upside is at most a one time 4x gain from here.

MetaFilter has its own problems. One common trope there is the angry, lonely person in their 30s-50s who paints the isolated life as beautiful and meaningful in order to feel better about themselves and possibly lure others into it. You see this the more you know the stories behind the usernames. The writing there is very nice at times, and I love that the small IRL communities have formed, but the discussion here is more honest and the advice is better.
That isn't the case.

Chrome supports multiple profiles. Mozilla's Multi-Account Container tabs isn't multiple profits. It is multiple isolated containers running under the same profile, in the same browser window.

A closer analogy would be if Chrome allowed each tab to have its own profile, rather than each window, and for each one to be lighter weight than a full profile.
The reason the ongoing drop in battery prices matters is that they are essential for the saving the environment by getting the planet off of fossil fuels.

That being the case, the relevant question is not whether the prices will continue to drop forever at the present rate. Rather, the question is whether they will drop low enough to make the transition possible.

Well, they are already low enough to do that for some uses, and a good deal more price reduction is expected in the coming decade, so it seems the answer is yes, they will drop low enough.
Solaris is gone[1]. Illumos a fork of OpenSolaris still lives on however.

What you are talking about is the USB to PS/2 converter. The "serial" they are talking about is UART. Something like this which is quite common for hobbyists to own already: https://www.amazon.com/WINGONEER-CP2102-Module-Serial-Conver...
Kind of surprised that Microsoft is doing this. The Trident rendering engine is actually really good, and does a better job with the ACID 2 test than Chrome does today.

While I agree with the overall content of this post, it seems dire to the point of hyperbole. Chromium is OSS, and Microsoft has both the incentive and engineering to fork it should Google not ultimately work together with them on it. It is somewhat ironic how Mozilla was basically founded due to Microsoft's monopoly on the browser market and when they (Mozilla) succeeded in breaking that monopoly, they give rise to a new competitor (Chrome / Chromium), which mostly does them in (Do them in being defined as steals most of their userbase).

I only really care that the web stays relatively open and vendor neutral, something Mozilla overall has been a real champion of. Microsoft using an open source standards compliant rendering engine is sort of a step in the right direction from where we were 10 years ago even if that rendering engine is primarily maintained by Google.
The idea is to use economic incentives to keep people honest rather than trusting centralized authorities which can be more easily compromised
I don't think you are wrong. I have both apps, and my last 10 rides have been in Lyft, because it's consistently cheaper. If uber wants me back all they need to do is compete on price, but I think their operating costs are too high to do that, so they will eventually lose out from being too big and have to either scale back or implode.
Personally, I think gofmt made the right call -- let the editor soft-wrap long lines. This is much nicer because you can then dynamically pick whatever window width you want. Hard wrapping defeats this.

(But of course there are downsides, because if you're in a context where the editor/viewer isn't soft wrapping, it's worse. Still, on balance, I think not manually wrapping lines is the way to go.)
Congratulations!

From my experience after the initial first two weeks. I would start work in my closed door office. My wife was only alone to gchat me if needed something. Obviously if it was an emergency, she could yell or come into the office.

When my wife went back to work 3 months later, I still worked at home. 3 days was ananny, and 2 days my parents. It was really refreshing for me to be near by with a new nanny. The nanny and my parents knew they could only chat me.

Working remote, you get to spend more time with your child, it's so awesome and you are not tired from the commute etc.

It helps that I'm extremely disciplined and I followed all the rules. Ultimately, it worked out fine. It's a little bit of adjustment money, work and relationship, but it all works out. Just when you think you got a system down, they start walking!

Regardless if you are work remote or on Mars. I can't emphasize enough taking a "Daddy Bootcamp class" that is generally offered at most hospitals.
I agree with you that on desktop the situation is a bit different. I 've only played around with UI on OSX, and for some reason it is way harder than native ui on ios (old NextStep api vs UI api).
Fonts are handled differently. The coordinate system is different (starting from the bottom left corner if I remember correctly). Coding for multiple screens; like tracking pointer position on windows on different screens is awkward. Lots and lots of legacy stuff.

Perhaps windows is better? What about linux? :p But I see why people are disliking the native ui situation on desktop.
One wonders, what if someone else had bought Be?
It took away credibility. A lot of it. It also alienated too many “almost evangelist” users (like me) who had converted countless users from other browsers in high school and college. Many of them haven’t been able to reconcile with what might seem a tiny change now. Also the jarring and bizarre way Mozilla pretty much stonewalled everyone on it who wanted it to be discussed.

I don’t know it would make sense to you, or most, but it felt like a breach of trust and seeing it is still baked into the browser itself (yes, they bought it; yes, you can turn it “off”) and that you can’t “completely remove” it, I don’t “that part” has changed. Besides the separate standalone add-on was a lot more useful and I was a full time user until that debacle when I moved to Safari (and Pinboard).
Not that I agree with the article but that is literally the opposite of what it said. The article says the voice is NOT the observer.
Computers are not the death knell for chess
Chrome doesn't have this. You cannot run tabs in different contexts in Chrome side by side.

Both additional profiles and incognito browsing open a different window, with its own settings.
If you’re worried about your kids being exposed to that stuff, set up internet filtering in your home. It’s pretty effective these days, and you’ll actually get way closer to the result you want with that approach than with trying to change the internet.
There are likely some positive articles about Facebook posted to HN daily too, but they don’t make it to the front page. There is a great deal of anti-Facebook sentiment here. An anti-Facebook article is much more likely to reach the front page than a positive one in this community, and that’s why it seems like HN is overrun with negative FB articles. Positive articles exist - they just won’t get upvotes here.
No. The certificate's expiration is fixed at time of issuance. You could set the expiration of the certificate to the expiration date of the domain, but the domain could be transferred, cancelled, or revoked before the expiration.
I didn't mean to make it out like Medicare was the sole cause (eg how health "insurance" got started by being excepted from the wage restrictions of the time, and how it continues to be exempt from income tax). But I think the analogy of musical chairs describes the present constructive behavior of the system quite well.

A no brainer step to reforming the health care market is to force all providers to publish a price schedule, uniform across any payer. We wouldn't accept grocery stores forgoing price tags and instead trying to gouge each person for as much as they can, and any free market rhetoric needs to incorporate that fact.

(Note this is orthogonal to what level of care should be guaranteed by the government)

"every hypothesis should be questioned."

It is, constantly, literally on a daily basis. That's how we know.

What does pop culture (Bill Nye) has anything to do with this.

Also many of us are a bit beyond just theoretical discussions. It's 2018. We are increasingly affected by climate change to the point that many of us are packing, because the shit already hit the fan. What's a fun theoretical discussion for you (at the moment) is actually life and death for many.
Ask HN: Which personal dashboard solution do you use?
I'm looking to organize all of my life's information into a single dashboard - things like financial, health, goals and progress information. For example, I want to be able to pull up the dashboard and see things like: My IRA info, bank balance, Apple Health data, analytics data for certain web properties I care about, stock information, perhaps a few posts from HN or certain Reddit subs I follow. Basically, all the things I might check on any given day, in one place so I just glance at it and be done. I imagine it would need the ability to add custom types of charts, perhaps connect via API to various services etc... Does anything like this exists?
Ooh, I also like the Dark Mode stuff. I was just thinking about how I love dark mode, but the fact that I have to enable it on every single site makes it kind of unwieldy. Having a media query for it seems brilliant!
Right, so don’t open pages in new tabs, open them in new windows instead? Literally don’t don’t click ‘open in new tab’ and you won’t get a new tab. Click ‘open in new window’ instead.
What's Party Reply? Is that another tool of Repl.it in autocorrect? Googled but didn't find much
If Go adds generics and a smoother method of doing error handling, I could see it eventually taking Python's place. It already is doing so to an extent, but with those features plus everything else it can do better than Python, it'd be tough to beat. 95% of my programming is in Python, and I honestly don't really enjoy coding in Go that much, but with those changes I could see myself switching.
No. There was some FUD which was spread that was eventually outed to be written by PIA, one of their competitors. The entire thing mostly just elicits an eyeroll.
> You're also leaking your IP address to any website you visit.

As opposed to leaking your VPN's IP address, which is about as meaningful.

> You're also trusting any other networks that you connect to when you open up your laptop in a coffee shop or hotel room not to have a sniffer sitting on them.

True. Which is why a personal VPN to your home network is useful.

> You're trusting tons of faceless organizations across the entire chain of you to the website you visit to be safe with your data.

The connection from the VPN provider still goes through a similar chain.

It's true that the chain will be substantially different if you, say, connect to a service in the US from the UK via an Australian VPN service. On the other hand, the chain will be way longer if you use that Australian VPN to look up your local pizza place's menu.
Ask HN: Are web/marketing agencies inherently difficult to scale?
I've worked for two agencies but have much more experience with one than the other (4 years vs a couple of months). I want to know if this is the typical life cycle of a web marketing agency that is largely B2B to small-medium businesses.

I saw their company in two different "stages" of its life when I've worked for them. First as a junior contract developer making about half of local median pay (the contract mentioned a shift to full-time with higher pay but never followed through on that). In my first time working there, the business was being run from another company's sublet rooms. Structure was "top heavy" over 50% being management that delegated tasks to off-shore teams. Being a local dev in the company was a rarity.

Two years have passed, at some point I was seeking work and decided to go back to my old company since the founder was interested in having me do consulting work for them. I was paid just slightly more than my time as a junior dev, and usually put projects that had clients that didn't interact with the other employees beside myself and the PM. It was very silo'd in. Pretty much, do the work that their regular employees don't have time for.

During this time they had already moved into their own dedicated office. There are still a lot of kinks in the armor but at least things feel more organized in the company. Local dev team is still barebones with the management largely directing off-shore workers. And then I started thinking, if this is 3 years of growth I wonder what is the next step to take this business to the next level.

Do agencies form some proprietary tech that make them attractive for large co's to pick it up and buy them? Is that a general case? I am not thinking of starting a business, but I don't see if there's, if any, way to properly scale up to a national level. Is the agency model just inherently restricted to scaling? Could they expand their vision and scale up?
If I ever interview with a company that would potentially reject me due to coding style, I really hope they do. That's not a place I would enjoy. Not that I am against a common style, I just think it's an extremely petty thing to reject a candidate for.
this is interesting.

could you point to some additional resources on this topic?
What I found interesting is how the CxO doesn't matter much to the industry. It's funny because VC want you to be passionate about the industry. But, if your into technology then to me it not so much about the "problem" as much as the technology and how to make it work. Should the CEO probably care about the problem probably. But the technology/science is more about the technology.
I recall reading something to the effect that the most competent developers by Triplebyte's metrics used vim and Ruby on a Mac. That sounded too much like the typical hipster startup dev to be a coincidence, which got me wondering: is that really a snapshot of the best developers out there, or is it just what Triplebyte, hence their clients, are selecting for?
> things using the new keywords that were introduced (e.g., "await") will no longer compile

That's not backwards compatibility, it's forwards compatibility. Whenever any language adds a new feature, using that feature breaks the build on old compilers. Setting `edition=2018` is no different. But the important thing is that old code continues to build unmodified on new compilers. That's what the edition system is preserving.
Well, on that tune I am sure there are users who’d love Fb and Tw integrations; and deep ones at that.
I guess it's fair to say the latest Safari's are much better, but over the last few years our web team definitely cursed Safari for issues more often than we've cursed IE.
Services like Pool/Express Pool/Line are distinctly different from taxi services in so far as opening up car-based transit to a broader range of socio-economic groups. The efficiencies of Express Pool make it competitive with public transit for pricing.
Does this mean we can finally login to U2F-required Google accounts from iCal?
manipulating JSON (really, just plain native language objects) is way more straightforward than manipulating the XML dom. The purpose of formats like this is to make inexpressible the kinds of documents that result in difficult to untangle bugs, and frustrating UI behaviour.

Using Incognito Mode to Avoid Google's Tracking? You Couldn't, Said DuckDuckGo
Chrome massacres my 2012 MBA, the fan spins up within 30 seconds of launch. Firefox runs smooth as butter, mucho tabs and no fan. It seems people have widely different experiences, very weird. I wonder if it's a graphics card thing.
disclaimer: I have no idea what jenkins is.

If you're okay with using chrome: create another profile and only use it for jenkins, in fact, set up a shortcut that opens it in app/kiosk mode and maybe see if there's a commandline flag to clear all history every time you open it, that way all you need to do is click the shortcut and everything else happens in the background and it doesn't affect the rest of your browsing exp.
Same. 99% of my back-end and robot code is Python. Maybe this is a grass is always greener kind of thing but I'm hitting projects of a size where I miss static typing.

I will say that asyncio is amazing and really solves concurrency for me. But Go looks like you also get parallelism without a lot of work.
