Title: I lost my ability to focus. I check social media and youtube frequently while doing work. If I do not do that I feel some void and feeling of losing out(I do not know how to express this).<p>How to regain my focus and avoid this trap? Upvote:

Title: I am currently a Linux administrator at a state university in the US. I do the standard variety of administrative things that one would expect: provision servers and VMs, manage storage pools, use monitoring tools to keep track of systems, use configuration management tools to automate installation and configuration of packages and services, etc, etc...<p>As more and more services and tools are rolled into cloud provider&#x27;s portfolios, I can&#x27;t help but think that there&#x27;s no point for me to exist. Here on HN, in person with other tech-minded people that I know, and elsewhere in the tech sphere, I&#x27;m bombarded with a viewpoint that boils down to: &quot;Be a developer, or get out of the tech industry.&quot;<p>Herein lies the issue. I have thus far been unsuccessful in any programming endeavors that I have attempted. I can manage to throw together bash scripts and other glue that&#x27;s necessary to make automation tasks function at my work, but these are largely cargo culted from various stack overflow posts or other online resources. Whenever I attempt to dive into anything that I would consider &quot;development&quot;, such as python programming, it&#x27;s as if my brain completely ceases to function and all of the words and symbols on my screen turn into an incomprehensible alien language. It doesn&#x27;t matter how long I stare at it or how much I reference the documentation, that alien language never reveals its true meaning to me.<p>This inability to understand syntax is not only saddening to me, it&#x27;s made much worse by a variety of mental issues that seem to amplify the issue, such as: PTSD, anxiety, depression, borderline personality disorder, and dyscalculia. All of these feed off of each other in a vicious cycle of frustration, hopelessness, self-loathing, and worse.<p>I suppose my question is:<p><i>Has anyone had a similar experience and managed to push through the mental blocks associated with learning to program while having your own mind constantly working against you?</i> Upvote:

Title: I was just hired as the first permanent data scientist in a big corporation. They’ve previously relied on consultants to build the infrastructure and the data science pipelines. We’re still around 10 people in the team.<p>The code is not pretty to look at, but this is not our biggest problem. We inherited a weird infrastructure: a mix of files in HDF5 and Parquet format dumped in S3, read with Hive and Spark.<p>Here are the current issues:<p>- The volume does not require a solution that is this complex (we’re talking 100Gb max accumulated over the past 4 years)<p>- It’s a mess: every time we onboard a new person we have to spend several days explaining where the data is.<p>- There is no simple way to explore the data.<p>- Data and code end up being duplicated: people working on several projects that require the same subset write their own transformation pipeline to get the same results.<p>Am I the only person here who finds it completely insane?<p>I was thinking about building a pipeline to dump the raw data in a Postgres and then build other pipelines to denormalize and aggregate the data for each project. The difficulty with this, and any data science project is to find the sweet spot between data that is fine-grained enough to allow to compute features, but fast enough to query to train models. I was thinking that in a first iteration, data scientists would explore their denormalized, aggregated data and create their own feature with code. As the project matures we could tweak the pipeline to compute the features. Do you have any experience with this?<p>Finally, I love data science and I really don’t want to end up being the person who writes pipelines for everyone. Everyone else is a consultant, and they don’t have any incentive to care about the long-term impact of architecture choices: their management only evaluates delivery (graphs, model metrics, etc.). How do I go about raising awareness? Upvote:

Title: Ola Bini, privacy defender, cryptography expert, free software developer, is currently detained as political prisoner in El Inca prison, Ecuador. He was arrested on Thursday afternoon, 2019-04-11.<p>This is the result of an irregular detention process[1], dubious claims of evidence[2], and by violating his legal rights. Many, including David Kaye - UN Special Rapporteur[3], have concluded that there is no real basis for Ola&#x27;s detention.<p>Ola&#x27;s detention is a threat not only to Ola himself[4], but to research projects, such as OTRv4[5], PET Symposium contributions[6], DECODE EU-funded project[7], free software projects Coy.IM, and everything Ola has done[8], in the past: programming language &#x27;loke&#x27;, Seph, JesCov, JRuby, JtestR, etc..<p><pre><code> &quot;The case against me is based on the books I&#x27;ve read and the technology I have.&quot; -- Ola Bini, statements from his imprisonment.

Title: Like many folks here, I probably spend too much time reading about, trying and contemplate using many new languages. The (overlapping) paradigms that interest me are metaprogramming, functional, and (newer) statically-typed. I decided to focus only on metaprogrammable ones from now on (as a time saver and to step up).<p>I made a list and ordered them by how much I would be interested in using them (which combines my curiosity with current&#x2F;expected adoption).<p>My short-list for metaprogrammable ones are:<p><pre><code> Clojure Elixir Nim Crystal Rust (would be higher if I did more low-level work) Pony </code></pre> I left most other functional ones off my list because that&#x27;s an exploration in itself for another time. I was surprised that I put Clojure and Elixir first given my preference for static types. Of all the kitchen-sink features that Nim has, I can&#x27;t accept camelCased == under_scored names otherwise it could have been first. Ruby is notably absent as I use it and am looking for something better&#x2F;different.<p>For future adoption, I think interoperability is a key factor, whether it&#x27;s with C or in a VM runtime (e.g. JVM, CLR, BEAM, v8).<p>Which metaprogrammable language do you use or are most interested in using? How compact are your programs (i.e. how extensive do you metaprogram)? Upvote:

Title: I run AutoTempest.com, a car listings search engine. A few weeks ago, someone registered autoStempest.com, with an extra &#x27;s&#x27;. They copied our logo and branding, as well as faking other information, such as their team and location. (For example, their &quot;CEO&quot; is actually the CEO of Edmunds.) They&#x27;ve taken other steps to appear legitimate, such as creating a fake Yelp profile and reviews.<p>From what we&#x27;ve heard from our users, they&#x27;re creating fake craigslist listings, and when people contact them, they&#x27;re directing them to links on their site, claiming to be &quot;Auto Tempest&quot;. Then they solicit payments (presumably reservations or down payments, if not complete sight-unseen purchases), while using our name recognition to gain trust.<p>We&#x27;ve determined that their registrar is Namecheap (as is ours, coincidentally), and they are hosted by a company called Quasinetworks, NL. Interestingly, if you google that company, the first result is someone complaining about how they were unresponsive to abuse notifications; not a great sign. We did sent a message to their abuse contact, but haven&#x27;t heard back. We also contacted Namecheap and did get a reply, but it appears they will only take down a domain with a) a court order, b) potentially a request from law enforcement, or c) a UDRP proceeding: https:&#x2F;&#x2F;www.icann.org&#x2F;resources&#x2F;pages&#x2F;help&#x2F;dndr&#x2F;udrp-en<p>The problem with options c or especially a is that they&#x27;re costly, and nothing would stop whoever is behind the site from simply registering a new confusingly similar domain. So, to start with we&#x27;ve submitted a report to ic3.gov, the FBI&#x27;s Internet Crime Complaint Center. Hopefully if they confirm the site is fraudulent, they can request that Namecheap yank the domain. I&#x27;ve never submitted such a complaint before though, so I have no idea how responsive they are.<p>Is there anything else we could do to shut these scammers down? Upvote:

Title: I&#x27;d like HN to experiment with a &quot;countless&quot; view of the site for a week. As in: all vote, karma, and comment counts are removed from all pages sitewide. An example of this idea is here: <a href="https:&#x2F;&#x2F;i.imgur.com&#x2F;OzE8qgq.png" rel="nofollow">https:&#x2F;&#x2F;i.imgur.com&#x2F;OzE8qgq.png</a><p>I suggest this as a mandatory-for-all sitewide test, as otherwise the compulsion to see integer counts (such as karma) will fork HN into two distinct communities operating within the same shared space. I believe that this experiment is valuable only if everyone participates, and since the data will remain present on the back end, no harm is done to anyone&#x27;s preferred integers of choice while the experiment is underway.<p>I believe this would be a good experiment for HN as I worry that HN is unintentionally causing addictive feedback loops with its pervasive use of counts. Counts are already today hidden in scenarios where the admins seem to have determined that people behave more appropriately when they are unable to see a precise integer ranking of other&#x27;s approval. I&#x27;d like to give the HN community a chance to experience the value of HN without the pressure of integer-ranking altogether.<p>The voting algorithms need not be modified for this experiment, as we already are able to flag comments and posts effectively without being able to see how many flags are present. The front-page links that say whether comments are present or not would simply be replaced with the word &#x27;discuss&#x27; to remove the pressure to &#x27;be seen&#x27; participating in posts, permitting one&#x27;s interest in the post and&#x2F;or topic to become the sole determining factor for participation.<p>I hope that HN is willing to entertain and implement this experiment and am curious to hear how the community feels about the idea.

Title: Received this email a few minutes ago:<p>&quot;On Thursday, April 25th, 2019, we discovered unauthorized access to a single Hub database storing a subset of non-financial user data. Upon discovery, we acted quickly to intervene and secure the site.<p>We want to update you on what we&#x27;ve learned from our ongoing investigation, including which Hub accounts are impacted, and what actions users should take.<p>Here is what we’ve learned:<p>During a brief period of unauthorized access to a Docker Hub database, sensitive data from approximately 190,000 accounts may have been exposed (less than 5% of Hub users). Data includes usernames and hashed passwords for a small percentage of these users, as well as Github and Bitbucket tokens for Docker autobuilds.<p>Actions to Take:<p>- We are asking users to change their password on Docker Hub and any other accounts that shared this password.<p>- For users with autobuilds that may have been impacted, we have revoked GitHub tokens and access keys, and ask that you reconnect to your repositories and check security logs to see if any unexpected actions have taken place.<p>- You may view security actions on your GitHub or BitBucket accounts to see if any unexpected access has occurred over the past 24 hours -see https:&#x2F;&#x2F;help.github.com&#x2F;en&#x2F;articles&#x2F;reviewing-your-security-log and https:&#x2F;&#x2F;bitbucket.org&#x2F;blog&#x2F;new-audit-logs-give-you-the-who-what-when-and-where<p>- This may affect your ongoing builds from our Automated build service. You may need to unlink and then relink your Github and Bitbucket source provider as described in https:&#x2F;&#x2F;docs.docker.com&#x2F;docker-hub&#x2F;builds&#x2F;link-source&#x2F;<p>We are enhancing our overall security processes and reviewing our policies. Additional monitoring tools are now in place.<p>Our investigation is still ongoing, and we will share more information as it becomes available.<p>Thank you,<p>Kent Lamb Director of Docker Support [email protected]&quot; Upvote:

Title: Hi everyone,<p>I am in a situation that I feel some of you can relate to, so I wanted to pose this question in hopes of generating some resources for myself and similar people. I&#x27;ve had a few developer jobs so far in life and on balance, I haven&#x27;t really liked any of them. When I ask myself why, the reason is always the corporate bullshit that I must endure. I find the actual job of being a developer quite fun and enjoy solving problems and building things with code. I also have no troubles with the interpersonal side of developing, as far as working in a team and being a decent coworker is concerned. What I cannot stand is the corporate environment and it&#x27;s associated crap and rituals. I don&#x27;t like being &quot;obligated&quot; to put in extra time with my colleagues on team events and retreats. I don&#x27;t like daily stand-ups that are about talking about what you&#x27;re up to so you look busy, rather than sharing (both ways) useful info with the team. I don&#x27;t like a lot of the personalities I have to interact with at work (IMHO, certain departments&#x2F;roles attract people who I feel are inherently dishonest or manipulative. These people creep me out and I wish I didn&#x27;t have to be so close to them every workday). Many who read this will be able to add a lot to this list of complaints, as I can too.<p>What I want is a remote dev job where I close tickets. That is, one where the gig really is cash for functioning solution that meets spec, code standards, and QA. My ideal world would be where I log in somewhere, pull a respectably specified ticket with clear acceptance criteria, and then pull request myself to at least a modest quality of life. Does anyone know of any remote work where the hassle is just engineering related? I will specify that I am not interested in simply transitioning the interpersonal bullshit to a Skype-based model, so team-intensive remote work won&#x27;t suit this requirement. My greatest thanks for any insightful thoughts or resources you guys can provide. Upvote:

Title: Starting with .org, .info, and .biz, ICANN is planning to eliminate the 10% annual cap on increases of prices that TLD registry operators can charge for domains, both new and renewals. These TLD registries have a monopoly on the entire TLD (they&#x27;re who <i>your</i> registrar buys the domain from when you order it), so you can&#x27;t just switch to a cheaper company without throwing out your entire domain and starting over from scratch on a new one. Large companies may be able to withstand large jumps in prices, but small businesses and individuals will bear the brunt of any increases that occur, increasing the already considerable centralization of the Internet. PIR (who runs .org) already makes $90 million annually from registrations, in exchange for maintaining a database and running some DNS servers.<p>ICANN is currently holding a public comment period, which closes today at 23:59 UTC for .info and .org, and May 14 for .biz.

Title: Hi HN community! We&#x27;re Rahul and Manmeet, co-founders of Trexo Robotics (<a href="https:&#x2F;&#x2F;trexorobotics.com" rel="nofollow">https:&#x2F;&#x2F;trexorobotics.com</a>) At Trexo Robotics, we&#x27;re building wearable robotic devices to help children with disabilities learn to walk, in many cases for the first time in their lives. Video: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;3LW4LJIpa2o" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;3LW4LJIpa2o</a><p>We are both Mechatronics undergrads from the University of Waterloo. Rahul later completed a Master&#x27;s in Robotics at the University of Toronto and I&#x27;ve done my MBA at Rotman.<p>We started this a few years ago when I (Manmeet) found out that my nephew, Praneit, has Cerebral Palsy, and that he would not be able to walk. Not walking can lead to contractures, hip subluxation, and many physiological and psychological issues for kids. We wanted to change that. We decided to use our robotics background, along with help from friends and the top rehabilitation researchers in North America, and in 2016, watched my nephew take his first steps using our device. Watching Praneit walk is definitely the proudest moment of my life, and we realized that there are families all over the world that can benefit from this, so we started Trexo Robotics.<p>The Trexo device is available for $899 per month (via financing) or can be purchased outright for $29,900. It is an exercise and therapy tool, allowing children to get the benefits of daily walking at their homes. We decided to design it so that it attaches onto an existing walker. Currently, it only works with Rifton&#x27;s Dynamic Pacer, but hopefully, we can add other walkers later on as well. Our controller allows you to modify the gait pattern to adapt to the needs of different kids and adjust the amount of force&#x2F;assistance that the robot provides on each joint. We are already launched, with kids using it to walk thousands of steps daily. It has been amazing to see the interest of families. Our device is available for pre-order. Our 2019 production is already fully reserved, and we are now taking reservations for next year.<p>Really interested to hear the HN community&#x27;s thoughts on our approach, and experiences families or others have had in this space.

Title: Try it out on your WiFi: <a href="https:&#x2F;&#x2F;tapchat.com" rel="nofollow">https:&#x2F;&#x2F;tapchat.com</a><p>I’ve always been shocked at the fact that it’s easier to chat with someone on the other side of the world than with someone who is on the exact same WiFi as you. I think that is a shame because WiFi networks are essentially a bunch of existing micro-communities which your phone already automatically connects to. Think about how many other people have used or will use the same WiFi as you at home, school, work, or in public; and so far it has been practically impossible to chat or share pictures with them.<p>After leaving my job earlier this year, I decided to work on a simple chat app that solves this problem, by simply opening a <i>persistent</i> group chat for every WiFi you connect to, which allows for long-lasting conversations and meaningful relationships everywhere you go. So far a great use case I&#x27;ve seen are college campuses where thousands of students connect to the same WiFi, and who can now all chat with each other. I&#x27;d love to see what else this can or will be used for.<p>(Spoiler alert: the app doesn’t bother with mesh networks)<p>Feedback is much appreciated! (the gentle kind) Upvote:

Title: Hello HN! We are Erik, Zach, and Tom, the founders of Centaur Labs (<a href="https:&#x2F;&#x2F;centaurlabs.io" rel="nofollow">https:&#x2F;&#x2F;centaurlabs.io</a>). We’ve built a platform where doctors, other medical professionals, and med students label medical images, improving datasets for AI.<p>The idea grew out of Erik’s research when he was a PhD student at MIT’s Center for Collective Intelligence. In short, he found that by aggregating the opinions of multiple people--even including some people with little or no medical expertise--they could reliably distinguish cancerous moles from benign ones better than individual dermatologists.<p>The three of us have been friends since we were undergrads. When we would chat about Erik’s research, it seemed like a no-brainer that there’d be demand for more accurate diagnoses. We all had our frustrations that as patients, you usually have to trust one doctor’s opinion.<p>So we built a mobile app called DiagnosUs where users around the world analyze medical images and videos. Many are doctors who simply enjoy looking at cases or want to improve their skills. Other users like competing with their peers, seeing themselves on our leader boards, and winning cash prizes in our competitions.<p>Different people (and algorithms) have different skills. Using data on how our users perform on cases with “gold standard” answers, we train a machine-learning model to identify how differently-skilled people complement each other and cover each other’s blind spots. The more we learn about our users’ skills and expertise, the better we get at aggregating their opinions. It is a bit like putting together the optimal trivia team: you don’t just need the five best people, you need someone who is good at pop culture, someone who knows sports, etc. Experts trained in the same way often have the same blind spots, so outcomes improve when you include a range of opinions.<p>We initially thought we’d go straight to providing opinions on demand for consumers like ourselves. There aren’t nearly enough doctors to meet the demand around the world to have everyone’s medical images analyzed. But it didn’t take long to realize that our fledgling startup wasn’t yet prepared to deal with the regulatory issues that would entail.<p>Meanwhile, we’d been hearing for years that AI was on the verge of replacing radiology, but it seemed like the hype didn’t match the reality. Many companies trying to develop medical AI are impeded by bad data. They try to hire doctors to go through thousands or millions of images and re-label them, but this has proven hard for them to manage and scale.<p>Our customers have giant medical datasets and want to use them to train AI. But the quality of the data holds them back, and they can’t find nearly enough doctors to label the data accurately. Our platform provides a high volume of labels quickly, and our performance analytics enables us to get highly accurate labels from groups of people with a range of skills.<p>We’d love to hear from anyone working on medical AI who’s faced the challenge of dealing with flawed datasets. If you’re interested in trying our app, you can download DiagnosUs for iOS in the App Store. Thanks for reading! Upvote:

Title: Hi HN!<p>We’re Joe, Martha, and Kunal; co-founders of Withfriends (<a href="https:&#x2F;&#x2F;withfriends.co" rel="nofollow">https:&#x2F;&#x2F;withfriends.co</a>).<p>Withfriends runs membership programs for small businesses. Bars, theaters, barbershops, can use Withfriends to convert their customers to become monthly-paying members. Members receive simple &amp; automated benefits, and small businesses earn additional revenue.<p>We’ve started by focusing on music venues and event organizers. All three of us come from a lifetime of organizing events, primarily in NYC. Joe and Kunal started a music venue and collective art space in Brooklyn, called The Silent Barn. Kunal started one of the first video game galleries, called Babycastles. Martha and Joe used to run a newsprint listing called Showpaper, which aggregated shows from hundreds of venues every week. We know that culture in cities is defined by the beloved small businesses around us, we know how cultural funding works and where it falls short. With our own businesses, we saw that by changing how we asked for support, we could radically change the volume of people funding our venues, and by automating member benefits, it was easy to facilitate them. After testing an early iteration of the product with a handful of organizers, we decided to bring these insights to a larger audience as Withfriends.<p>How does it work? We found that people are most willing to purchase a membership when asked in the checkout flow, with their credit card already out. Instead of asking business owners to promote memberships as an entirely new product, we integrate with the point of sale to sell memberships as an add on to any purchase. This makes selling memberships as easy as selling tickets for any small business, so they can start today. Withfriends uses point-of-sale APIs to make this possible, and automates member benefits directly in the POS, like presale and discounts. Any business can write in custom member benefits in addition to Withfriends benefits, but we have data from over 100,000 purchases to date on the platform, so we start each business with a proven set of membership tiers and benefits specific to their business as soon as they sign up. We’re taking infrastructure that has been proven by large institutions like museums, and making it accessible to any small business organizer anywhere, whether they have a staff of 50 or only 1.<p>We already are working with over 85 small businesses around the country, and have 5500 members supporting them. We&#x27;ve generated an average of 40% additional revenue for our businesses. We’re making $6k in MRR, and our membership revenue is growing 30% month over month.<p>Much of our initial traction last year was from our own networks, relying on an invite-only approach to new sign-ups, and we activated each and every membership program by hand. This taught us a lot, but since joining Y Combinator we’ve been focused on preparing for the public by automating the setup flow. Now anyone can become an organizer on Withfriends in minutes, and start growing their members with every upcoming event. This has allowed us to jump from 7 small business sign-ups per month before Y Combinator to over 70.<p>When we began, we took a 5% fee of the membership revenue, and charged ~$1 per ticket when an organizer uses our native ticketing. That pricing is the same as other ticketing or fundraising platforms, but none of them offer businesses the 40% revenue boost that Withfriends creates for our customers. Since then, we&#x27;ve built an integration with Eventbrite that allows organizers on Eventbrite to easily sell memberships too - in that case, we only earn membership fees. We believe memberships are our strength, so we&#x27;re testing new pricing that focuses on membership revenue entirely. By making memberships for small businesses easy and successful, we’re thrilled to help them grow and become more sustainable.<p>It’s an honor to be able to share this idea with the Hacker News community and we’d love to hear what you all think. If you have any music venues or event organizers that you would like to be a member of right now, we have a referral program open which you can access at this link (<a href="https:&#x2F;&#x2F;withfriends.typeform.com&#x2F;to&#x2F;P80RQX" rel="nofollow">https:&#x2F;&#x2F;withfriends.typeform.com&#x2F;to&#x2F;P80RQX</a>) and we’ll buy you a membership and some tickets once they sign up!<p>Look forward to hearing from you all,<p>Joe, Martha, Kunal Upvote:

Title: This really kind, eccentric guy in my neighbourhood is stockpiling books and has been doing so for years. He has an enourmous barn that he is obsessively filling with whatever reasonable quality books he can get his hands on but he is completely overwhelmed in terms of cataloging&#x2F;indexing them so customers have to go through his barn sifting through cartons full of books. He charges $1 or $2 for whatever book you dig out.<p>He buys bulk lots from deceased estates and bookstores that are closing down. Entire shipping containers are being gifted to him and showing up at his barn. The barn is full and he is now storing in shipping containers outside.<p>There is great quality books among this quagmire but it takes hours of searching to find them. I figured HN might be able to point me to a solution where I could quickly photograph the front cover and have a script&#x2F;google images compare the image to online info to index the title and author and then perhaps list them online...<p>I dunno, it just seems like such a treasure trove of books that he will sell for practically nothing because he loves books and hopes that they will find their way to people who want them - the barrier is allowing customers to find what they are looking for.<p>Thoughts?

Title: I&#x27;m writing a book about the role of software developers in the global economy.<p>One of the book&#x27;s themes is that developers hold a strange kind of power: we get to make decisions in code that affect end-users but only other developers (and sometimes not even then) can really hold that code to account before it goes into production. Seemingly mundane decisions in code can have profound consequences.<p>I&#x27;m gathering stories from people who&#x27;ve had to take decisions like this and especially where it was in a domain for which they had no experience.<p>I&#x27;d love to hear from people on HN who have stories to share.

Title: I am a technical cofounder at a startup. We are a small company (team of ~5) around a year old, with 1-2 years of funding left before we will need to raise again at our current spend levels. I think we have a good chance of getting to a successful place with our company and doing that round successfully, which could be life-changing financially for me and my family (I come from a middle class background). The technology is also exciting to work on.<p>Recently, my young daughter started going through a few health difficulties. Our startup works a little harder than an average engineering job (maybe typical for a seed stage silicon valley startup). Unfortunately I am not really able to balance my family life commitments (the number of appointments that I need to attend, along with the extra support my wife needs), with the demands of the startup. I feel like I am doing a bad job at both.<p>I have been think returning to a regular software engineering job at a big tech company, perhaps the same one I worked at before this startup. I should be able to balance much better (more cash, more time, and less psychological involvement with the job). However, I feel guilty leaving the company and the team, and worried it could really set the company back at this crucial stage. It also feels like the current situation of me trying to balance both isn&#x27;t sustainable either.<p>Sorry for the ramble. Anyone have any advice here on how to think about such a decision? Upvote:

Title: Hi HN! I’m Rob, Founder of Prometheus. We’re removing CO2 from the air and turning it gasoline, diesel, and jet fuel. Since we use zero-carbon electricity from sources like solar and wind to make our fuel, there are no net CO2 emissions when you use it.<p>An article about us came up on HN recently and people seemed interested (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19792412" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19792412</a>), so we thought it would be good to try to answer some of the questions we saw there and try to dive in some more to any questions that follow!<p>The only inputs to make the fuel are CO2 and water (both from the air) and electricity. The only outputs are fuel and oxygen. One way to think about it is that making fuel is reverse combustion. The process isn’t super efficient (we expect 50-60% overall efficiency at maturity), but it turns out that doesn’t matter as long as the electricity is zero carbon and low cost. If the cost of our equipment is also low, then we believe we can not only make zero carbon fuel, but actually compete on price with fossil fuel.<p>We’re not the first to make fuel from the air - in fact Google, Audi, Carbon Engineering, Global Thermostat, Climeworks, and labs at universities and national labs have all done it before us. What no one has been able to do so far is do it at a low enough cost to compete with fossil fuel.<p>The thing that’s new about what we’re doing is that we have gotten rid of all the thermal processes normally used, and instead use a process that uses only electricity (no natural gas, etc) and does it at room temperature. This is a big deal for both capital cost and for being truly carbon zero. We can use inexpensive materials, which keeps our cost low, and can start up and shut down quickly, which allows us to run intermittently, matching the intermittent nature of many renewable energy sources. We can also only run when the power is at the price we want.<p>Digging in to some more details, we absorb CO2 and water vapor from the air into an aqueous electrolyte. We then react the CO2 in the water with a copper catalyst to directly make alcohols like ethanol, butanol, propanol, etc. Both of these things have been done by many others and the science is known. Normally at this point one would have to use a thermal process (distillation) to get the fuel out of the water, and this is expensive and makes the economics really hard to get right. We don’t have to do this step thermally though, because we have a carbon nanotube membrane that replaces it, extracting the alcohols from water in a single step at room temperature. This makes a huge difference in cost. The last step is that we up-convert the alcohols to gasoline, diesel, and jet fuel. This last step is also well known and we can actually buy this step from others.<p>The carbon nanotube membrane that makes this all work is the product of 6 years at my previous startup, Mattershift. I was developing it for desalination and water purification. About 3 years ago I realized it could do this job, but it wasn’t clear that a startup could raise money for such an ambitious effort, especially one linked to a political issue (unfortunately) like climate change. When I saw the YC request for startups in carbon removal, I knew that the timing was right, and I founded Prometheus to do it.<p>Please let me know if you have more questions or feedback. I’ll do my best to answer any questions, but please excuse if I’m not able to go too far into details like our piping and instrumentation design, or other really specific things we wouldn’t want to help competitors with.<p>Thanks!

Most of the time when I am traveling I am in locations that have poor or nonexistent cellular service.<p>This often causes problems with services (Paypal, banking apps, messangers, etc.) due to my inability use two factor auth and text-message based confirmation messages.<p>It seems to me that phone numbers are a horrible identifier due to the way they can be transferred between users of a carrier. Services like Ting have made short term numbers easy to use, and I often get two-factor auth messages from previous users of a number.<p>Is this purely a business case for data mining, or is there a legitimate security reason for relying on something as ephemeral as a phone number for critical identification mechanisms?<p>I have debated using Twilio to create my own number pool of international numbers and a way to check my messages via a web portal instead of relying on messaging.

Title: 15 years ago I learned Python by studying some O&#x27;Reilly books and I have been a hobbyist programmer ever since.<p>The books went into detail and since reading them I&#x27;ve felt confident writing scripts I needed to scratch an itch. Over time, I grew comfortable believing I had a strong grasp of the practical details and anything I hadn&#x27;t seen was likely either minor quibble, domain specific, or impractically theoretic.<p>This was until last year when I started working on a trading bot. I felt there should be two distinct parts to the bot, one script getting data then passing that data along to the other script for action. This seemed correct as later I might want multiple scripts serving both roles and passing data all around. Realizing the scripts would need to communicate over a network with minimal latency, I considered named pipes, Unix domain sockets, even writing files to &#x2F;dev&#x2F;shm but none of these solutions really fit.<p>Googling, I encountered something I hadn&#x27;t heard of called a message queue. More specifically, the ZMQ messaging library. Seeing some examples I realized this was important. The step of then plowing through the docs was nothing short of revelatory. Every next chapter introduced another brilliant pattern. While grokking Pub&#x2F;Sub, Req&#x2F;Res, Push&#x2F;Pull and the rest I couldn&#x27;t help breaking away, staring in space, struck by how this new thing I had just read could have deftly solved some fiendish memorable problem I&#x27;d previously struggled against.<p>Later, I pondered the meaning of only now stumbling on something so powerful, so fundamental, so hidden in plain sight, as messaging middleware? What other great tools remain invisible to me for lack of even knowing what to look for?<p>My question: In the spirit of generally yet ridiculously useful things like messaging middleware, what non-obvious tools and classes of tools would you suggest a hobbyist investigate that they otherwise may never encounter?

Title: I am working on a project but I have limited resources since I don&#x27;t have a job currently. I am looking if there are any good alternatives to DigitalOcean with support for additional disks&#x2F;volumes, that do not cost too much. I have tried several providers including UpCloud, Hetzner Cloud, Vultr and Linode. UpCloud seems to have the best performance but all of these apart from Hetzner charge $40&#x2F;month for a cloud server with 4 cores and 8 GB of ram. Hetzner gives me twice as much memory at half of the price, but performance isn&#x27;t great from my testing&#x2F;benchmarking, especially concerning the storage. I would use UpCloud if pricing was more affordable. I will probably need 7 servers for my setup initially with 4 cores and at least 8 GB of ram and decent storage performance.

Title: In an attempt to de-Google my life, I recently disabled Play Services. Now, my Pixel 2 XL complains every time it can&#x27;t &quot;phone home.&quot;<p>Google wants to contact Play Services (itself a rootkit) every time you receive a call. You&#x27;ll see the notification&#x2F;complaint several seconds <i>before</i> the phone rings.<p>While driving with Maps, Google attempts to track you each time you enter a destination or cancel one as well as at regular intervals during your drive.<p>Play Services also tries to track me at random times for no reason when I&#x27;m not using the phone.<p>It tries to track you while listening to voicemail and the notification&#x2F;complaint stops the voicemail playback every few seconds when it can&#x27;t.<p>But perhaps the worst offense is that it tracks you <i>as you scroll through your contacts.</i> God help if you look up a phone number because, every few seconds as you scroll through your contact list, Play Services attempts to report it to Google.<p>I find this behavior reprehensible and I&#x27;m sorely looking forward to getting a Puri.sm or &#x2F;e&#x2F; device.<p>Just for fun, try it for yourself by disabling the Play Services app and see how often Google is spying on <i>you.</i> Upvote:

Title: Looking to get some feedback from the Hacker News community.<p>I wrote the book with a focus on penetration testers and red teamers, but there are great examples for network admins, developers, and blue team defenders as well.<p>You can pick up a copy for free here through May 19, 2019: <a href="https:&#x2F;&#x2F;gumroad.com&#x2F;l&#x2F;the_cyber_plumbers_handbook&#x2F;hackernews20190518" rel="nofollow">https:&#x2F;&#x2F;gumroad.com&#x2F;l&#x2F;the_cyber_plumbers_handbook&#x2F;hackernews...</a><p>Please note, because it&#x27;s hosted on Gumroad, it does require an email.

Title: I&#x27;d made a similarly titled post[1] a couple years back and I seriously don&#x27;t know what kind of usage DuckDuckGo has right now. But I&#x27;d like to think that it is extensively used, at least in the developer community. And I strongly believe that people should start degoogling their lives at least slowly and gradually if its not possible to do it at once. If more people start using DDG, the search engine will improve and that least that one aspect of degoogling could be achieved to a certain extent.<p>[1] https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=13284917 Upvote:

Title: As React webapps get large and start to contain a lot of complex components, they often do not perform well and manifest low FPS in browser. As a result, engineers add strategies such as memoization (React.memo, shouldComponentUpdate) to avoid unnecessary computation, however they logic is fragile to code changes.<p>Is there a way to automatically test performance (maybe in terms of FPS) of React applications regularly in CI pipelines? Any tools for this out there? Upvote:

Title: It has been two months joining a company as a fresher. I was pulled into the project within a month. I am comfortable working as a shadow for the project. Recently I as well as others with 1-2 years of experience were asked to prepare a resume which is to be sent to clients for acquiring few projects. Even though it has been just 2 months, I was asked to showcase myself as a developer of 2 years of experience. I promptly said I cannot do that. They accepted it, but then submitted my resume to the client not only as a developer of 2 years of experience but also with fake projects that I had never worked on. They told me this is how other companies also work and there is nothing wrong in &quot;pumping up&quot; the resume. I again went to the HR and said I can&#x27;t be a part of this process, as my conscience does not allow me to do that. They were polite and accepted my reasons. But I could see that they are really not happy with what I did. I have just started my career and not sure what will be the consequence of my decision. I am willing to lose this job instead of faking my resume.<p>Did anyone has been in this situation? How things went by when you refused to do such kind of unethical activities? Did you get punished indirectly? Is it a common practice in all companies? Upvote:

Title: I&#x27;m a junior developer and in a process to get ADD-diagnosis.<p>I find it very hard to stay focused at work, especially if the task in hand isn&#x27;t something I&#x27;m passionate about. Even bigger problem I&#x27;m facing is that it&#x27;s almost impossible to stay aware on what we are discussing in the meetings. My mind just constantly wanders away from the subject and this leads to embarassing moments and me missing crucial knowledge about the project.<p>I&#x27;m looking for practical tips and personal experiences on how you manage to stay productive and focused during work day.<p>Thanks in advance!

Title: I wrote a piece in my wiki about tools &amp; methods I use to stay focused.<p>https:&#x2F;&#x2F;wiki.nikitavoloboev.xyz&#x2F;focusing<p>I found this system to work well for me. It&#x27;s a Trello board of goals separated by time. Weekly&#x2F;monthly&#x2F;quarterly&#x2F;yearly. Where month goals are ideally based off my year goals and week goals are based on month goals. This kind of system gives me structure and focus and I allocate time with events based on the goals I have set. And more importantly it gives long term perspective to the things I do now &amp; the things I want to achieve in life.<p>The link also goes over some nice tools I use to automate distraction as I have most &#x27;news feed&#x27; like websites blocked (front pages of twitter&#x2F;hn&#x2F;lobsters&#x2F;github&#x2F;..). And only have few times I can actually visit those sites with goals of intentionally viewing them and not out of a habit.<p>I also try to systemize as much as I can to the point where I create some guidelines ([rules](https:&#x2F;&#x2F;wiki.nikitavoloboev.xyz&#x2F;focusing&#x2F;rules)) I wish to follow. It helps me keep things in order and I iterate on them as I gain more experience.<p>I am curious what systems &amp; methods you guys found that work well for you to achieve this goal of being more mindful of your time and the things you truly want to be doing in life?

Title: I wanted to become and entrepreneur my first business in my UG as a design studio was a huge success. Had many clients and made some money.<p>I built a product next only to become a failure. Later I tried launching one more company &amp; 4-7 other software products which also failed or never saw the launch.<p>My friends who were leading a normal 9-5 day jobs are getting promoted to 6 figure salaries and Managements positions.<p>I am in my 30&#x27;s. I do have a contract job as a designer now. But also trying to succeed as an entrepreneur on the side.<p>Feeling like I should just give up and try to catch up with the rest of the world.<p>When I try to see the future, I no longer see a successful entrepreneur. Instead a middle aged man with failures.<p>I am 30 now. I should choose the right path.<p>Anyone who went through the same and then either succeeded or gave up. I would like to know your views. Thanks a ton in advance. Upvote:

Title: And if so, which software do you use? I&#x27;m fascinated by storing things that I learn outside of my own brain. Ideally I&#x27;d love to create my own mini intranet of information, basically a personal wiki, that I can go to first before having to Google things, especially for my field of study.<p>I&#x27;ve looked into various Wiki packages but none quite seem to offer what I&#x27;m looking for (Mac, no need for a webserver, cross device functionality, math markup, searchability, tags)<p>If you do keep a personal knowledge repository, can you please describe your workflow for using and maintaining one for all the new knowledge you acquire?

Title: Hey all. I lost my co-founder and best friend 3 days ago in a car accident. We are a startup of 5 people and he was the CEO. We are all friends and this has deeply affected us emotionally and I know that, without him, the startup will be on life support soon. What are we supposed to do? many online services were attached to his email, he was talking to customers, he had loaned a lot of money to the company, he was raising capital, he was recruiting... he was pretty much the father of the company. We are lost and any tip would be greatly appreciated.<p>Thank you very much HN. Upvote:

Title: I will start a job as a software dev and with the job offer comes a bunch of contract clauses that basically lets the company own all IP while employed. I am from a third world country, so I won&#x27;t be able alter the contract clauses. With these restrictions in place, what can I do while employed to have a better chance of succeeding when I do start a company?<p>My plan :<p>- continue learning while on the job<p>- prepare for interviews so that I can apply to companies that are friendly to side projects (stripe, gitlab, github and a bunch of other such companies. Please mention companies that are ok with remote workers and are side project friendly, even startups paying $30,000 work for me)<p>- build side projects in my free time that demonstrate my skills<p>- maybe participate in Pioneer.app tournaments so I can network<p>- basically work on stuff that won&#x27;t become a company<p>- once I get a job at a more side project friendly company, I&#x27;ll start working on my ideas.<p>As you can see, it&#x27;s quite a shitty situation to not be able to pursue my side projects that could become companies, but it is what it is and I want to make the most of the next year or so. Any suggestions would be appreciated. Thank you. Upvote:

Title: I&#x27;m working for a German automobile corporate in Spain as a project leader. I&#x27;m 29, I&#x27;ve studied electronic engineering, I don&#x27;t have kids, and I&#x27;m not married. What I do at my current job all day is emails, spreadsheets, power points, and some electronic testing. I&#x27;ve been working there for already five years, and I&#x27;ve been climbing the ladder as much as I managed. I also work on the afternoons on a side project that is making close to $100&#x2F;m<p>However, my day job is draining all my energy in a way that I am grumpy from Sunday night to Saturday morning. I wake up at 6:20, commute 45 minutes, work 8h, commute 45 minutes, arrive home at 18:00 and then I try to squeeze time for my side project, going to the gym, making groceries, hang out with my gf, etc. I probably push around 10h&#x2F;week to the project. The worst part of it is getting home exhausted in a way that it&#x27;s impossible for me to do any work done. It makes me feel miserable, depressed, and tied. I could create more value just by myself. During my office hours, my energy levels are, and the atmosphere at work is pleasant. Also, my salary is above the Spanish average, but nothing special, my uni friends are also making similar numbers.<p>My gut is telling me to quit my job and work for my products. I have enough savings to survive for five years. I don&#x27;t think about going nomad or any of these hippie trends. I&#x27;m focused on building a business and feel accomplished by something I&#x27;ve done with my hands.<p>My biggest fears are: - To not stick to a schedule&#x2F;routine once I am solo. - People&#x27;s and family opinion. - Failing and losing motivation.<p>Should I quit my job and work on my stuff or search for another position that would give more motivation?

Title: I&#x27;m a project manager for a ~60 person software dev firm. One project I&#x27;m on is with a large American enterprise, and the product owner and his direct manager are absolute assholes.<p>I&#x27;ve got 8 developers that I try to shield from accusatory questions and extremely aggressive and borderline abusive behaviour. In the beginning we we all agreed not to take anything personally and to let it just roll off the back. We agreed to tighten up our processes and try to avoid confrontations by being super proactive with all our work, but we&#x27;re coming close to the launch date, and it&#x27;s getting worse as more pressure mounts.<p>Ordinarily, we would have dropped the client by now and refused to put up with the end-justifies-the-means tactics, but unfortunately our company could not survive without this and a handful of other projects we have with this client.<p>My company is actively looking for new clients so we are not beholden to this one, and my manager is apologetic and tries to run interference when she can, but I&#x27;m largely left to my own devices. This is a very high profile project that stands to disrupt its market. It&#x27;s exciting for them and us. I have to maintain this relationship somehow.<p>How do you manage your clients who are completely unreasonable, rude, and treat you and your staff extremely poorly? Upvote:
