    Should this list filter companies that are shutdown or have been acquired and no longer have an active product? Many of the links are "our incredible journey" acquihire announcements or just 404. I understand and appreciate the value of having a list of all developer services companies that have gone through YC, but as a developer resource page it's annoying to see a product that might fit my needs but is long shutdown.

      Good point - I'll filter those out.

      Is Paul Graham and Robert Morris's Arc language[a] being used for anything in production other than Y Combinator websites?

        I'm curious about this too.

        There still seems to be interest in the project. The forum gets new topics posted every few days [1] and Anarki, a community ran fork of Arc, shows recent commits [2].

          Hubski was originally based off the HN code and continued development in Arc (https://hubski.com/pub?id=126759).

          They were converting from Arc to Racket, but I don't know how much ended up being done (https://github.com/hubski/hubski/wiki/Converting-Arc-functio...).

            https://www.laarc.io/ uses it. It's a HN clone created by an ex-employee from S2 (which develops Heroes of Newerth, a Dota clone). It's available on github as well. https://github.com/laarc/laarc
            • hjek 6 years ago
              Looks like a fork of HN, so not really created by this S2 ex-employee.

              I don't think so, although as the sibling says there is hobby activity. Interestingly enough, though, reddit was originally written in arc, but they later rewrote it in python. Make of that what you will.
              • jedberg 6 years ago
                As sibling said, reddit was CL before it was Python. But more importantly, reddit predates Arc by more than two years. :)

                And the main reason reddit was rewritten was library support. Doing simple things in CL was hard because you had to write it from scratch, but doing those things in Python was a simple library install.

                • 20190220 6 years ago
                  I'm curious because I thought the main draw of CL was that it was easy as heck to roll your own library support.
                • blue1 6 years ago
                  Reddit was written in Common Lisp, not Arc.

                I'd love to scan down the relevant YC companies list, but it's really hard for a human to visually parse: https://i.imgur.com/1u457oA.jpg

                A little white space would be helpful.

                • badfrog 6 years ago
                  Agreed. Just adding some bottom padding to the table cells does wonders for readability: https://imgur.com/9FBgrT9
                  • newsbinator 6 years ago
                    Exactly. With good padding and a bit of extra white space and maybe a faint border, it would be possible to notice that the description for Airship (w2018) is missing.

                    I would have done something like this: https://i.imgur.com/Ck96siZ.jpg

                    Looks like they were in a hurry to get this site out.
                  • snowmaker 6 years ago
                    Agreed. We had to rush this page out for a Google-driven deadline. I've just fixed the formatting like you suggested.

                    > Beating the Averages

                    > A classic article on using powerful programming languages as a secret weapon

                    I'm surprised this is included given that it's been more or less been proven to be false. Almost every valuable company in the past 2 decades was built on a blub language. Facebook even used PHP! Java and C++ are at the core of most Amazon and Google services. There basically haven't been any big companies build on a lisp-like language unless you consider Scala, but even the most companies adopted that later.

                    edit: blub

                    • lisper 6 years ago
                      > it's been more or less been proven to be false

                      Not really. It's true that few big winners have used Lisp, but that would only disprove the thesis if there were also companies who tried using Lisp and failed. AFAICT, no one is even doing the experiment.

                      I actually know of two notable counterexamples: Barefoot Networks has an internal design tool written in Common Lisp that is a significant source of competitive advantage for them. Also Orbitz.

                      • fnord123 6 years ago
                        Keep in mind the at that Beating the Averages is from 2001 (revised in 2003). This means that it predates Java 1.4 and obviously C++11 (let alone C++14, 17, etc)

                        Most languages have the features of CL that made it so useful. Even Java has first class functions, lambdas, partial application, async IO, etc. Java even has a repl now. The only things left afaict are macros (non-hygenic in CLtL2) and code-as-data/eval (a security hole).

                        Aside from pulling from functional languages, Java also learned Python's 'with' using try-with-resources. Meanwhile the tooling of Java went from strength to strength and it's a serious blub factor for people who haven't used Java.

                        Beating the Averages was fairly spot on at the time it was written, but since then it's lost it's power as features of blub languages was merged into existing languages.

                          If not commercial Lisp, what you think about using Racket for both the IDE and so they can pre-scale by giving HtDP to good developers who want to learn Scheme?

                          According to Alan Kay, Smalltalk was an explicit attempt at making something as dynamic as Lisp, but where one wasn't "coding in your data representation." There was very high representation in the Fortune 500, and some very big business applications. Much of the natural gas in North America was scheduled on a Smalltalk application. JP Morgan used Smalltalk to manage very large portfolios at one point. I could go on about the applications I know about personally for hours, actually.

                          The line blurs, however, as Java was very much inspired/influenced by Smalltalk, as was the CLR and C#. Ruby and Python were also highly influenced by Smalltalk. Javascript was influened by Self, which was effectively the "Son of Smalltalk." Smalltalk, at one point, was also cited as being a "blub" language. (No templates, no macros, no explicit multiple inheritance...)

                            "Almost every valuable company in the past 2 decades was built on a bulb language."

                            But did they succeed because or despite those languages?

                            Would they have been even more successful and would their code have been more maintainable, more easily exapandable, had more power or more flexibility had they used Lisp?

                              What's a "bulb" language (or what did you mean to type that got autocorrected into "bulb"?)

                                Had to look that up — do you mean a blub language?

                                  Maybe OP just believes that writing PHP, Java, or C++ feels like walking on broken light bulbs. :)

                                  I personally don't mind working with those languages, as long as I'm not working on a horribly written legacy codebase.

                                  I just noticed that clicking on 'About YC' (top, next to YC logo), results in a 404. Looks like the link contains a '/' too much: https://www.ycombinator.com//about/

                                    Wish they didn't use the .dev extension.

                                    It should be developers.ycombinator.com

                                      Yeah, have to update my local DNS routes. I had .dev pointed to 127.0.0.1

                                        This has been the topic of HN for the past few days for anything .dev.

                                        You should be using .test or .localhost for any development domains: https://tools.ietf.org/html/rfc2606#section-2

                                          I did this years ago. Developers have been using .dev for decades, these TLDs are pretty new.

                                            .corp, .home, and .lan are also reserved, just not codified into an RFC yet.

                                              Until someone buys test.

                                              Will a boycott .dev site movement take hold?

                                          I thought that the .dev extension had mandatory HTTPS due to HSTS preload. Yet, this loads as "Not Secure" HTTP for me.
                                          • TonnyGaric 6 years ago
                                            According to https://get.dev/#benefits: >The .dev top-level domain is included on the HSTS preload list, making HTTPS required on all connections to .dev websites and pages without needing individual HSTS registration or configuration.

                                            What browser are you using that you are not redirected to https://yc.dev?

                                            >Most major browsers (Chrome, Firefox, Opera, Safari, IE 11 and Edge) also have HSTS preload lists based on the Chrome list. (See the HSTS compatibility matrix.)

                                              A somewhat out-of-date Chromium (69). I should upgrade, but I'm surprised the change is that recent.
                                              • CydeWeys 6 years ago
                                                In Chromium, the whole HSTS preload list is expired if it gets too out of date, as domains are both added to and removed from the list. So you're giving up real security by running an out-of-date browser. Not only are HSTS-preloaded TLDs not secured, but even, say, gmail.com or yourbank.com aren't. See: https://chromium.googlesource.com/chromium/src/+/lkgr/compon...

                                                I think it'd be better to use an out-of-date list instead of nothing; I should go push for that again.

                                                    Can you confirm that it's not rewriting the URL to https://yc.dev first before issuing a request to the network? It's possible that Safari has suffered some kind of regression. This definitely used to work at some point.

                                                    I can confirm here in Chrome and Firefox that the URL is rewritten internally to https://yc.dev (which then redirects to https://ycombinator.dev), so no unencrypted traffic is ever sent over the network.

                                                      Strange. I wouldn't expect that, because according to https://caniuse.com/#feat=stricttransportsecurity, the latest versions of Chrome and Safari for iOS do support Strict Transport Security.

                                                  I wonder how many of the YC companies use the other YC companies. And which are the most / least used. How much effort do you reckon is put in trying to "align" them and keep them aligned? As in there's a consistency in (e.g.) docs, APIs, etc.

                                                        Anyhow, it would be rejecting the argument of the blog post to link to it there, and the blog post itself is a bit of an increase incoherent mess (the author proudly identifies as female, adopting one label, and seems to equally proudly adopt the tech worker label, yet rejects the woman in tech label with the argument that rejecting all labels is essential to inclusivity. This is both incoherent on a surface level, and deeply problematic in that labels are the interface the human mind uses to deal with the world; rejecting all labels is rejecting all ability to model and interact with the world.

                                                          I didn't read her article that way. I read it as "Creating a new box to push people into defeats the purpose of opening up the boxes of 'Women' and 'Tech Workers'". She's alright with the labels of "Woman" and "Tech Worker" because they're (relatively) open groups. There's a wide range of people who fit into them. On the other hand, when people are talking about "Women in Tech", there's an image, and expectations surrounding that.

                                                          Embracing her identity as a woman gives her a place to build her character from. Being a "Woman in Tech", the way she's using the term, pigeonholes her into acting or looking a certain way, for fear of the dissonance it might create for someone else.

                                                            Sure, but overdoing it and confusing labels and abstractions with the things they represent can also keep a human from being more aware of the world and their deeds in it. I gladly reject the label "women in tech", but mostly because I actually do reject the label "tech" (and all stemming from that) to begin with, that's an umbrella so huge as to be meaningless. It's like "business", yeah I know what it is, just like I know what "technology" means, for any sensible use of these words, there's a million occurances where it's just padding at best, a cloak at worst, precisely a tool to not accurately model the real world, but a platonic simplified one that is easier to navigate than the infinitely fuzzy mess reality is.

                                                              Sure, abstractions are not the underlying reality, the map is not the territory, and the Tao that can be told is not the true Tao. That doesn't mean that it is necessary to “reject all labels” as a fundamental requirement for inclusiveness, or even that rejecting all labels is useful or even possible given the way human minds work. It certainly means we need to understand that all labels obscure as well as explain, and understand where each is useful and where each is counterproductive.

                                                              But that's not what the blog post in question is arguing, or if it is intended to be it is not argued well.

                                                              Labels, and words in general, while making it possible to communicate concepts to other people, also inherently make gross generalizations of those concepts, which confuses communication. Labels are therefore also used to “label” people, which is considered a bad thing. Therefore, some people really don't like labels.

                                                              I know women who feel the same way as the writer you cite. They want to just do their thing without being singled out as different, and don't feel the same need for solidarity that the "women in tech" women do.

                                                              That's a valid viewpoint. But I don't see the "echo chamber effect" you're talking about. I think most people seeking out the "Ask a Female Engineer" series are aware of other viewpoints that exist.

                                                              The main thing I wish they would do under that heading is link to the category, not just one of the blog posts. https://blog.ycombinator.com/category/ask-a-female-engineer/

                                                                      • nabnob 6 years ago
                                                                        I find myself somewhere in between the two viewpoints - I think there are a lot of factors that lead women in the United States to pursue careers outside of STEM, and factors that cause women in STEM to leave their tech careers later in life. I don't think it's a coincidence that many of the women in STEM that I know (including myself) are first or second-generation immigrants.

                                                                        At the same time, I'm skeptical of attempts to increase the number of women in STEM fields, especially those sponsored by major tech companies or venture capitalists. They seem like thinly-veiled attempts to increase the pool of potential workers and decrease wages - the same way that these tech companies lobby to increase the number of H1B visas. I think the best way to work towards ending discrimination towards women in the industry, and also discrimination towards immigrants (without decreasing wages) is organizing tech workers collectively.

                                                                        • porpoisely 6 years ago

It would be interesting to see the differences or similarities in opinions, perspectives and experiences of both genders. Or maybe just an "Ask an Engineer" blog where both genders' views are provided.
                                                                          • nabnob 6 years ago

                                                                            • mkane848 6 years ago

The viewpoints of minority groups are interesting, but, the very categorization of “Ask a Female Engineer” excludes all women who feel like the article I linked to (and apparently there are more than a few of them). Furthermore, the category “Ask a Female Engineer” does not even acknowledge the existence of this viewpoint – it misleads the reader, who is probably from a majority group, into thinking that this is how all of the minority group members feel. Which is why I thought it might be useful for a reader to know about the existence of this alternate viewpoint, by the inclusion of a simple link, explaining why the very categorization of “Female Engineers” is problematic for some, even those who otherwise would belong to it.

                                                                                  Edit: I was just guessing at the ratio of male to female engineers, so maybe I overestimated the imbalance, but I think the point stands.

                                                                                  • UnpossibleJim 6 years ago

I get that you're being pedantic, before you start to explain yourself, but still.

                                                                                    EDIT: Maybe tax forms, but I'm not sure the legality of that... but I think it's still the census.

It means "ask an engineer", and every engineer should know that due to lack of specificity the term does not exclude female engineers. Would you also imply that "ask a doctor" means "ask a male doctor"? What about "ask a nurse" or "ask a teacher"?

                                                                                  I see it pretty high up on the site, and I thought the consensus is that nowadays most languages have enough lispy and functional features to give similar productivity.

                                                                                  Is there any benefit from hyperflexible languages high enough to outweigh the benefits of readily available libraries?

                                                                                  • brlewis 6 years ago

I say that as someone doing mostly JavaScript and TypeScript development day by day. I often miss the clean syntax and macro facilities of Scheme. I used to use Kawa Scheme a lot, which runs on the JVM, so readily available libraries were never a problem.

                                                                                    Libraries, documentation and community are reasons to use non-Lisp languages for certain projects, but if you don't have some kind of Lisp in your toolbox, you're still missing out in 2019, in my opinion.

                                                                                                    Wow, it looks like they paid $11,500 for the yc.dev and ycombinator.dev domains [1]. (I guess that's a pretty small amount of money for YC.)

                                                                                                    I have my eye on some short .dev domains too, but I'm hoping to get one for $350.

                                                                                                    [2] https://domains.google/tld/dev/
