New top story on Hacker News: Am I the longest-serving programmer – 57 years and counting?
Am I the longest-serving programmer – 57 years and counting?
22 by genedangelo | 14 comments on Hacker News.
In May of 1963, I started my first full-time job as a computer programmer for Mitchell Engineering Company, a supplier of steel buildings. At Mitchell, I developed programs in Fortran II on an IBM 1620 mostly to improve the efficiency of order processing and fulfillment. Since then, all my jobs for the past 57 years have involved computer programming. I am now a data scientist developing cloud-based big data fraud detection algorithms using machine learning and other advanced analytical technologies. Along the way, I earned a Master’s in Operations Research and a Master’s in Management Science, studied artificial intelligence for 3 years in a Ph.D. program for engineering, and just two years ago I received Graduate Certificates in Big Data Analytics from the schools of business and computer science at a local university (FAU). In addition, I currently hold the designation of Certified Analytics Professional (CAP). At 74, I still have no plans to retire or to stop programming.

New top story on Hacker News: [EU] Any job boards and age-friendly companies for older SW Developers?
[EU] Any job boards and age-friendly companies for older SW Developers?
21 by nonines | 19 comments on Hacker News.
I've spent last year interviewing only to find out that I'm considered too old (I'm 45) for most shops around. They won't spit it out directly of course but people talk and what they say is that I need to be stellar or young to be hired. Companies won't invest in me the slightest bit, so the moment I miss a question in the long interview process I'm out of the door without second thought. So... 1. I might be banging the wrong doors. E.g. FAANGs don't seem to be right. Any companies that don't drink/sell the youth cool-aid? 2. I might be searching at the wrong job boards. Any suggestions welcome. 3. Finally I might be better doing sth else altogether (but what?) rather than fighting a loosing battle against preconceptions that run so deep. Anyway. Thanks for any non-insulting answers in advance. PS: I'm based in EU and I'm a SW Dev working mainly in DevOps and Reliability.

Ask HN: Has anybody shipped a web app at scale with 1 DB per account?
23 by bradgessler | 28 comments on Hacker News.
A common way of deploying a web application database at scale is to setup a MySQL or Postgres server, create one table for all customers, and have an account_id or owner_if field and let the application code handle security. This makes it easier to run database migrations and upgrade code per customer all at once. I’m curious if anybody has taken the approach of provisioning one database per account? This means you’d have to run migrations per account and keep track of all the migration versions and statuses somewhere. Additionally, if an application has custom fields or columns, the differences would have to be tracked somehow and name space collisions managed. Has anybody done this? Particularly with Rails? What kinda of tools or processes did you learn when you did it? Would you do it again? What are some interesting trade offs between the two approaches?

Show HN: r/hnblogs, Blogging is not Dead

Link: https://ift.tt/2zhWXiy Old Reddit Link: https://ift.tt/2XrGeB5 Hi HN, Inspired by this post earlier this week: https://ift.tt/3bPYM37, I thought we could make blog discovery easier by having a place to find interesting, unusual, niche, or really any kind of non-marketing blogs that are posted by the people that write them. There are a ton of interesting blogs on the web, probably more than there were when the web was new, but even though there's more they're a smaller percentage of the total internet and hard to find. Search engines fail to help with this for a lot of reasons. They're both not incentivized to find this kind of non-ad, non-sales content, and there are lots of sophisticated actors trying to game search engines to show their own content. Regular people just writing interesting blogs who don't have an interest in SEO will be lost in that shuffle. HN and Reddit are great for link aggregations, but rely on submissions and upvotes which skew things to more generally popular content. The volume of posts also make it hard to compete (even though I really like HN and find the content interesting). The restriction to only allow posts from the authors of the blogs should help and the writer can interact with the community. The end goal is to generate a wiki on Reddit reminiscent of old 90s 'portal' pages with curated links to interesting content. We have a small initial community from my HN comment on that other post (https://ift.tt/2Xt42EK), but if you write a blog and want to join please do!

Interviewed with Triplebyte? Your profile is about to become public
34 by winston_smith | 5 comments on Hacker News.
Fortunately this email made it through my spam filter. Looks like they want to take on LinkedIn and are planning to seed it by making existing accounts public unless you opt OUT within the next week: Hey [redacted], I’m excited to announce that we are expanding the reach of your Triplebyte profile. Now, you can use your Triplebyte credentials on and off the platform. Just like LinkedIn, your profile will be publicly accessible with a dedicated URL that you can share anywhere (job applications, LinkedIn, GitHub, etc). When you do well on a Triplebyte assessment, your profile will showcase that achievement (we won’t show your scores publicly). Unlike LinkedIn, we aim to become your digital engineering skills resume — a credential based on actual skills, not pedigree. The new profiles will be launching publicly in 1 week. This is a great opportunity to update your profile with your latest experience and preferences. You can edit your profile privacy settings to not appear in public search engines at any time. Our mission is to build an open, valuable, and skills-based credential for all engineers. We believe that allowing Triplebyte engineers to publicly share their profiles and skills-based credentials will accelerate this mission. Thanks, Ammon Co-founder & CEO, Triplebyte

Ask HN: Why isn’t visual programming a bigger thing?
25 by remolacha | 52 comments on Hacker News.
Visual programming seems to unlock a ton of value. Difficult concepts can more easily be grokked in a visual form. Programming becomes more approachable to first-timers. Since text is difficult to manipulate without a physical keyboard, visual programming opens the doors to doing development on mobile devices. And yet it only seems to be mainstream in education (i.e. Scratch). Why?

Ask HN: “Git” for MsOffice...?

I’ve recently changed job and now I am basically swamped in MSOffice documents. This makes collaboration very hard: people are fearful you’ll touch their precious files, there are manual procedures to produce “gold” documents, fixing a typo is an ordeal, and if the same slide is present in 15 Powerpoint decks any edit will require tons of mindless and error-prone copypasting... it made me realize how good developers have it with git, github, and the likes. Is there anything out there, capable of working with MSOffice stuff in a granular and collaborative way? I can’t believe non-geeks have lived like this for 30 years.

Ask HN: Production Lisp in 2020?

I have gone through initial chapters of "Practical Common Lisp"[1] and "Loving Common Lisp" [2], and have a bit of intuition on lisp, and the power of macros. Haven't done any projects yet, but was also researching on real issues faced by adopting lisp, and ran into articles about abandoning lisp [3], adopting lisp [4],[5]. Could not find anything more recent; but what they mention in these articles - even the ones that are adopting lisp talk about issues like: * poor ecosystem of libraries - few gems, most other half-baked * poor community coordination * Dependency management limitations with quicklisp And some specific red flags like: * poor support for json[6] * poor support for async * have to restart the server every 20 days because of some memory leak [3] * hack to tune GC [5] If you are using lisp in production for non-trivial cases, do these issues still exist? is there a way you can quantify effort is resolving them, and if yes, what is it? and, finally, if you had to re-do your project, would you chose lisp or something else?

Some MVNOs are offering plans as low as $6/mo. The only reason I'm keeping my cell is to make calls. Now I think by switching to a cheaper plan, I can save at least $30/mo. Have you done this? If it's not too much to ask, can you say which plans work better for calls?

It seems that since I had a kid my career is in decline. I am currently working from home, but prior to this I would need to be home at a specific time to watch the kid. This obviously means I have less time to spend at work. Less hours means less dedication in the eyes of management. On a side note, I took parental leave last year and was basically told by a manager friend that it means a lower rating. What is your experience?
