>"drag-and-drop data transformation pipelines that comes with app integrations at both ends"

Parabola is very focused on data transformation/manipulation. Our best customers end up with hundreds of steps in their flows, essentially creating full-fledged programs. As part of this focus on data transformation, we primarily operate in a batch-processing fashion. We also perform calculations live while you work on your flow, similar to a spreadsheet or a python notebook.

Zapier on the other hand is great at connecting with TONS of tools, and makes integrations between those tools really smooth. It operates best in an event-based paradigm when you don't need to do much transformation/calculation in between connection points.

There's probably a small amount of overlap at the edges, but in general it's pretty clear when a use case will be a good fit for a tool like Zapier or when it's a good fit for Parabola.

My Asus Zenfone 3 has a lot of flaws, but the battery life is awesome. After a day of very heavy usage, I'll still have over 50% battery life. Light usage usually leaves me with 80 to 85%. It makes up for the flawed custom android they put on it. If only it was stock android, as you say.
Wish the first one had had an OLED screen, but I guess that's impossible to get.
While I agree if you’re going Android make it stock Android comment, I know tech people who prefer Samsung’s software.
I have. Oy.
No framework will save you, it's not about language or framework at that point, they necessarily won't help you, but they can sure hurt you. It's more about your architecture.

I still find it completely confusing when programmers say engineering. Are you talking about real engineering jobs like civil and mechanical engineering or do you mean programming?
Erlang won't have helped twitter. Erlang has a very simple architecture, once they sent you a message and know it has reached your device, they no longer care about it. Twitter has to keep all the tweets, likes, retweets, show it all followers in real time. 100x more demanding than WhatsApp simple deliver and forget.
I don't think Apple has a legal burden to have a coherent policy. They can refuse service to anyone.
But what API do you use that you can get the data faster?
Is there a disconnect between the Silicon Valley elite and the population, when it comes to hardware and privacy? I feel, more and more, that my stance is anachronistic.
>Most sites do nothing more than throw GA on their website, and maybe some Adsense

That actually is a problem. GA is a clear violation of everyone privacy.
Interestingly, the UI was among the most praised features of windows phones, and still has a number of fans.
Strongly agree. Android came to dominate not because of great business, design, or engineering prowess on the part of Rubin but because of the economics of its ecosystem. Google revenue shares with carriers, who in turn demand devices from carriers with Google software. Meanwhile, the user base builds up with a wide variety of phones spanning many user preferences and budgets, leading to a huge market for app developers. You could have put anybody in charge, put out even worse phones, and still achieved smartphone dominance given the economics of the system.

The fact that Android is now also the best choice for users has little to do with the design decisions in the early days.
You could've just done absolutely nothing. That would've avoided service disruption.
I don't see what leaking personal information has to do with collecting crash data, or using Google's infrastructure to store my data. Why should I have to be on the hook for what is most definitely much safer than trying to safeguard the data myself?

Like I said, all it will accomplish is discouraging projects like mine that aim to provide utility to some people. One of my released hobby apps is no great commercial success (I don't show ads or collect revenue), but it's one of the top rated apps in its category on the Play Store, and I have about 20k DAU.

If the GDPR ever came after me for it, I'd just take the app down. Bam, 20k people a day affected because of over regulation.

Also, I wouldn't equate personalized ads with the life and death regulations involved in the auto industry.
Your last paragraph is pretty much where I stand. I'm not trying to fire a shot in a language war. I'm not trying to build a perfectly-architected Gang of Four masterpiece. I'm not trying to produce a mathematically beautiful perfectly-stateless category-theoretic treatise. I'm just trying to write a program that does something.

So I don't really care about FP ideology or OO ideology. I'll pick the tools that best let me get my work done. If that offends purists, that's their problem.

As to your actual question, a reasonable, unbiased discussion of tradeoffs... sorry, no, I don't have one.
I’ve come to believe that ‘are we at full employment?’ is the wrong question
That response could easily mean that they saw that there was an interaction where a message was recorded and sent without the device getting confirmation beforehand which matched what was reported to them, not necessarily that they kept the content of the conversation and could play it back. That's also a paraphrased conversation reported by a possibly non-technical person and likely passed through a customer service representative, so I'd take any technical details gleaned from it with a grain of salt.
If the entire contents of the data center were pressurized, would it increase the efficiency of air cooling? (Denser air -> more heat capacity?)

This website is really nicely designed. I can't quite place it, but I feel very good just looking at it. I can tell it was designed with care.
Greetings!

I'll get straight to the point. I've used Node-Red (https://nodered.org) in building my own IoT network along with automating quite a lot of things. I run my own Node-Red instance locally as well as online. Node-red has 1500 different functionality plugins, including things like "push flow to another node-red installation". Node-red also uses javascript as its frontend and backend. I can share whole code by giving someone the js block - which means that backing up flows is trivial. Sharing is also as easy.

So, I looked at your solution. It seems like a prettified version of Node-red with backup, js, and lack of ecosystem.

So, what's your buy-in? What're you doing better than a spare VPS running node-red? Not everyone is going to install and maintain a server.... but you're here on HN. I'd say that 95% or higher could get Nodered up and running here.
Can you point to a section of copyright law that makes that distinction?
Is it that wild or political to support a leader trying to protect China from communist rule and the cultural destruction caused by Mao Zedong? It doesn’t seem political so much as just supporting basic human rights.
>It does have the assets to let 100% of its depositors withdraw their accounts once its investments mature

This line of thinking is what caused the 2008 crisis. The two metrics are interdependent. If a bank doesn't have liquidity, it can't make loans, which cant support the prices of the assets it owns which results in financial collapse.

Ponzi schemes are 'investment' promises that require ever growing layers of patsies to be recruited for each patsies' pay off to occur.
Fractional Reserve is a practice where an institution leverages themselves by only keeping the expected liquidity needs in reserve and using the other capital for other means. Eventually they blowing up, when the market demands the apparent liquidity.

A ponzi scheme has to continue to grow or else it will collapse. Frantional reserve risks can perpetuate indefinitely until the liquidity is request:

StableCoin takes $100MM in USD deposits. Issues 100MM StableCoins. StableCo notices that it's 'never' had more than $10MM in USD of liquidity tapped. It decides "Hey we could make a stack of cash investing the remaining $90MM USD in XYZ" not until X years later does the fractional reserve issue arise as 'unforeseen circumstances' cause a liquidity demand of $15MM
Ha, I now see it and realize I upvoted it as well... which is also why I think I missed it. The upvote arrows act as a bullet point and thus I think I skipped right over that one since it was missing.
The result of which is ... ?

Does this lead to some occurrence such as a mass extinction or something of that nature?

Seems interesting.
No, I'm suggesting they don't add any more compliance rules with new punishments unless they staff up.
This is a nice article. I teach mathematics at a community college and the last section of article resonated with me. What can we do about education of mathematics to improve it?

Years ago it dawned on me that most of the students taking a class of mine needed the class so that they could take physics. It’s been a long time since I took physics and I don’t really know what math problems students in physics classes have. I went to the physics department and asked for a list of types of mathematical mistakes that are common. Give me the list and I’ll make sure I emphasize this in my classes. No response.

I’ve since learned that what my students really need to know to be successful in physics really isn’t covered in course that is a prerequisite. I’m not really sure why I teach the topics I’m required to cover. They mostly are to give my students enough knowledge to take calculus and almost none of them end up taking calculus. I think things are done the way they are because it’s always been done this way.

Change is slow and hard.
Extremely bizarre move frankly. I assume this was some kind or vigilante decision rather than based on recommendation of counsel.
Nice job, remote work?

I fantasize about doing similar, but I live in NZ, so even if I branched out to somewhere in the middle of nowhere in Australia I'd probably be looking at at least 100k USD for a decent place. Still, sure beats 300k USD minimum for a place in a city.
That doesn't really address the issue that the use of Facebook's software supports Facebook. The industry needs to pay more attention to the long-term results of its choices and actions.

There are alternatives to React too, like Vue.
Obviously this is meant for companies or individuals without developers or technical skills. If you have the technical knowledge a lock in service like this doesn't make much sense.

The problem is that someone without a technical background won't initially see the value in a tool like this and I doubt non technical companies/individuals will need as much automation to justify it's price.

Edit: I think a much more sensible pricing would have been to offer a desktop app and then charge users for the automations they want online on a consumption basis.
This is the correct way to do it. I would say that a negotiated Salt isn't necessary and infact should be discouraged. Let the Server use its mystery SALT to make it impossible to use rainbow tables should the database get hacked.
If you completely ignore the violent history of the industrial revolution and reduce prosperity to statistics like population growth, it's such a happy story!

I for one am totally happy that the day is accurately cut into precise pieces so that the best time can be sold off so that I can eat.

Economic history doesn't need to be tinged with a teleological and moral angle-- unless you got something to sell.
Python is the de facto language for the deep learning part of data science, the interface to TensorFlow, PyTorch and Keras. Others may be possible but all the examples, books, etc. use Python.
I like Jim Gray's simple explanation (as always) of the difference.

A database has two white marbles and two black marbles.
Transaction T1: Update all white to black.
Transaction T2: Update all black to white.

A serializable database will ensure that the transactions happen in some serial order. At the end of performing them one after another, either all marbles are white or all black.

In snapshot isolation, T1 updates only the white marbles, T2 updates only the black marbles. So they are not seen as conflicting. The end result is that the database contains 2 black (formerly white) and 2 white marbles (formerly black),because the two transactions are working off a snapshot and not conflicting.
In which direction? Apple is the “elite” or “luxury” brand and also one of the few to take privacy dead seriously.

I think the general population is more happy to give up privacy for cool features built using their data than you may think (unless I’m reading your comment backwards. It is phrased rather ambiguously)

Article could have been a fascinating survey of research on the topic but couldn’t resist bringing politics into it. Really ruins the piece when the author has a clear axe to grind.
Similarly, I don’t understand why so many people think ICE manufacturers will be able to effortlessly build electric vehicle lines. You can’t just use the same suppliers and infrastructure.
You know a Coke bottle, right ? That has a design patent.

Other drink makers are not allowed to make the exact same bottle shape. But you can still make a bottle. And you can still make a bottle that is very similar to the Coke design. But it can't be nearly identical. Translate that to Apple's home screen and that's what we are talking about.
I've tried that, years ago, using a similar rough-draft kind of mockup engine. I still got comments on the styling, and comments along the lines of "this doesn't look finished enough for review".
It takes time. Everyone who considers these issues should speak up.
Their phone was literally set up for failure. It had nothing new to offer over any of the established players, initial price was among the flagships, it had a broken camera, no headphone jack, buggy software. Basically inferior in every way and priced the same as Samsung's S8.
Good stuff. At the end of the day - self discipline and focus are the keys to success.
Do you think that engineering a house is more "engineering" than engineering a social network for 2 billion people?

> If I'm on the sidewalk and take a step toward the road, should it make the car jerk?

No. That's my point. Take less drastic measures earlier, and only escalate when you have to. That's how I drive, and a self-driving car can do the same.
Catch faces?

Hit heads perhaps?

As in, “Ouch! I caught that camera with my face.”
More transformations it looks like. You could probably pipe things through Google Sheets to replicate most of what this is doing but that’s an extra step. The whole point is to eliminate those.
Ask HN: How do I improve?
I just recently started a new job, and I love it. However I believe I'm clumsy, there were times when I send out the wrong emails and several times I made mistakes on the emails. There were times when I didn't thoroughly test of my code, and end up having to do an emergency deployment to fix it. I feel like to talk too fast, and had to stop mid sentence to catch my breath. My supervisor said not worry, I'm still on my probation and that he expects me to make mistakes. I'm worried that I won't improve over time. Did any of you experience anything like this? How did you improve?
Well, it’s probably not that bad. I think it’s more like google makes everything work ok, apple tries to really nail core functionality and let the rest slide.

Music interaction is a great example of the trade off.
I suppose for most thinking rationally, it seems like "stop doing business in the EU" is different than "make it like you've never done business in the EU". Taken to its conclusion, which Instapaper surely won't, it's not going to be easy to punish a business that has cut ties with the EU because of what they collected before. Granted it appears that with the law, like its predecessors, practicality of reasonable enforcement takes a backseat to intent.
Ah, I read that Twitter thread a few days (weeks?) ago and it was much longer. As far as I remember, it started with someone asking Twitter ops people, former and current, to share some stories about things that went spectacularly wrong.

It contained a lot of Twitter ops battle stories, some very interesting. I was pretty impressed to read Twitter internals in the given level of detail, but now it seems that the thread that held them all together is protected (probably didn't expect it to be so popular, or just wanted to continue more privately).
To quote from the abstract: "any device with a thrust-to-power ratio greater than the photon rocket would be able to operate as a perpetual motion machine of the first kind, and thus should be excluded by the First Law of Thermodynamics" seems pretty categorical to me.

The problem is, when you look at an object with a given velocity v, it has a kinetic energy proportional to v^2. To accelerate it from 0 to v, you must have put in all that kinetic energy (ie, v^2 energy). But reactionless drives give you velocity directly in proportion to energy. At some point, the v^2 and v lines will cross, and your object will have more kinetic energy then you put into it in the first place.

For every unit of energy you pump into the drive, the velocity goes up by a unit, but since the kinetic energy of the object is proportional to v^2, at some point the kinetic energy you get out will be more than the electric energy you put in. The problem goes away with photon drives because that crossing point turns out to be at the speed of light.

This is the argument the paper is making: If you can generate velocity directly from energy, you will eventually end up generating more energy than you started with.
Not to mention that cars these days come with headlights, a radical new feature that provides road illumination in the absence of streetlights.
We’re near the Kroger in Oakley.

It’s strange the mix of technology different stores have. One store near us (Hyde Park) has the equipment to effectively scan items into your cart as you go to pay without a checkout line, but doesn’t have the new food kits.

As far as the kits, I don’t think we’ve tried them. My family has been pretty happy with Hello Fresh, so we haven’t tried the Kroger kits. The thing I have found particularly difficult with meal kits is how they handle kids. It can be hard to expand palettes and cooking styles, but still have something that two adults and two kids will still want to eat (let alone be able to make it fast).
He's also the same guy who said, and I quote, "compliance is easy, just read the law."

It surprises me how much this community tolerates such combative cluelessness.
Yes I do. If more people got training or specifically we had some building codes or ethics training about how to make a social network that isn’t harmful to those millions that participate in it, we might not be in the state we are in right now.
>without also mentioning AKS which is much more mature IMHO.

AKS is anything but mature.It's barely working. Last month I was at Microsoft event and everyone was suppose to launch an environment. By the fifth or six environment, provisioning died and no one could provision an environment. And I mean it died globally, regardless of the region you tried to run it at. Provision time is awful even when no one is "stress testing" the provisioning engine.

This is all good and acceptable, relatively, when the service state is labeled as preview, which is how it is labeled officially. Mature isn't a word to use in regards to AKS currently.

The hype Microsoft advocates try to build around AKS gives the impression a highly puffed CV of a junior dev, and IMHO it is unfortunate and a wrong way to build trust. It is fine that Azure haven't yet developed state of the art kubernetes cloud service, no one except Google have, just don't claim you did if you want us to believe you when it labeled GA that we can use it for real workloads.

There has been one successful model for new entrants into the smartphone market, since the iPhone: start with a low-budget phone, and progressively raise your prices and move to more premium products as you build trust among consumers and retailers. It's what OnePlus did, it's what google did with nexus, it's what Xiaomi and Huawei have been doing.

Andy Rubin thinking he could skip this process and just jump in at the top of the market was pure hubris, and as much as I was hoping to see them succeed, it's a little bit reassuring that they failed. Success takes hard work, and essential skipped a lot of that.
No headphone jack, no removable battery, no sd card. Any one of those is a deal-breaker for me.
Approximate counters are much much older than HyperLogLog. Here’s something from 1978: https://www.inf.ed.ac.uk/teaching/courses/exc/reading/morris.... Of course this solves a different problem because HyperLogLog is an, uh, interesting way to count followers (why would you need to do a count-distinct query? You can’t follow someone multiple times). In any case, the Flajolet Martin sketch dates back to 1985 and solves the same problem as HyperLogLog: https://en.wikipedia.org/wiki/Flajolet%E2%80%93Martin_algori...

How much of the content in those sites change as fast as Twitter does? Mainly static content can be displayed using about any framework/language. Moreso when you include caching. I don’t think Rails was simply a good choice for the workload Twitter needed to support (not that they knew it at the time).
