These color codes were approved by the National Safety Council in 1944 and are now internationally recognized, having been mandatory practice since 1948. The color coding went as such: - Fire Red: All fire protection, emergency stop buttons, and flammable liquids should be red - Solar Yellow: Signifies caution and physical hazards such as falling - Alert Orange: Hazardous parts of machinery - Safety Green: Indicates safety features such as first-aid equipment, emergency exits, and eyewash stations. - Caution Blue: Non-safety information, notices, or out-of-order signage - Light Green: Used on walls to reduce visual fatigue ]]> green design history color-theory faber-birren control-rooms industrial-design color-coding https://pinboard.in/ https://pinboard.in/u:jm/b:4817a29dbe1d/ 2025-10-06T10:08:19+00:00 https://nvartolomei.com/oswald/ jm oswald wal object-storage s3 gcs azure smr storage formal-methods design architecture cloud-computing https://pinboard.in/ https://pinboard.in/u:jm/b:f7539b20cbc1/ 2025-01-23T16:33:53+00:00 https://github.com/slatedb/slatedb/issues/454 jm errors api design slatedb api-design error-handling exceptions architecture https://pinboard.in/ https://pinboard.in/u:jm/b:96f66b5f9f7e/ 2024-10-30T15:54:40+00:00 https://spin.atomicobject.com/capability-feature-flags/ jm apis design coding capabilities feature-flags flags https://pinboard.in/ https://pinboard.in/u:jm/b:a2496c3513d1/ 2024-07-15T09:33:20+00:00 https://dev.to/stripe/designing-apis-for-humans-object-ids-3o5a jm api design development programming stripe apis ids object-ids coding https://pinboard.in/ https://pinboard.in/u:jm/b:0173ac820a13/ 2023-11-14T12:39:20+00:00 https://rehanvdm.com/blog/should-you-use-a-lambda-monolith-lambdalith-for-the-api jm The argument to limit the blast radius on a per route level by default is too fine-grained, adds bloat and optimizes too early.

They didn’t have the astrolabe or the sextant, the compass or the chronometer. They did however have aids of a sort, which though seemingly humble, were in fact the repositories of an extremely complex kind of knowledge. Called Rebbelibs, Medos. and Mattangs, today we call them simply “Stick Charts.” ]]> cartography design history maps polynesia stick-charts navigation seafaring https://pinboard.in/ https://pinboard.in/u:jm/b:fff857421ec1/ 2023-03-20T11:04:51+00:00 https://blogs.scientificamerican.com/sa-visual/pop-culture-pulsar-origin-story-of-joy-division-s-unknown-pleasures-album-cover-video/ jmThis plotting of sequences like this, it started just a little bit earlier when we were looking at potentially drifting subpulses within the major pulse itself. So, the thought was, well, is there something like this peak here, which on the next pulse moves over here, and then moves over here, and over there. Actually, would be moving this way in that case – either way. I think Frank Drake and I published a paper in Science Magazine on exactly that issue – suggesting there might be drifting subpulses within the major pulse, which would then get back to the physics of what was causing the emission in the first place. So, then the thought was, well let’s plot out a whole array of pulses, and see if we can see particular patterns in there. So that’s why, this one was the first I did – CP1919 – and you can pick out patterns in there if you really work at it. But I think the answer is, there weren’t any that were real obvious anyway. I don’t really recall, but my bet is that the first one of these that I did, I didn’t bother to block out the stuff, and I found that it was just too confusing. So then, I wrote the program so that I would block out when a hill here was high enough, then the stuff behind it would stay hidden. And it was pretty easy to do from a computer perspective. ]]> design joy-division music science physics pulsars astronomy cp1919 dataviz https://pinboard.in/ https://pinboard.in/u:jm/b:5857d82604fc/ 2021-05-19T11:29:32+00:00 https://www.mukama.com/en/ jm edc keys wallets tools gadgets design https://pinboard.in/ https://pinboard.in/u:jm/b:f03246060569/ 2020-08-20T10:26:30+00:00 https://irelandcoins.ie/percy-metcalfe/ jm coins history ireland numismatism design art money https://pinboard.in/ https://pinboard.in/u:jm/b:b4185452585f/ 2020-08-04T12:26:49+00:00 https://www.designedbycave.co.uk/2020/LEGO-Interface-UX/ jm lego ux ui design funny https://pinboard.in/ https://pinboard.in/u:jm/b:73ce2c81c8cc/ 2020-05-27T13:47:21+00:00 http://blog.presentandcorrect.com/27986-2 jm soviet control nuclear design history power dashboards control-panels buttons lights beeping https://pinboard.in/ https://pinboard.in/u:jm/b:e3da3b082e18/ 2020-03-15T13:08:39+00:00 https://www.projectopenair.org/ jmWe are working on medical devices, such as open source ventilators, to have a fast and easy solution that can be reproduced and assembled locally worldwide.

An operator that doesn’t routinely operate the system will have atrophied skills if ever called on to take over. Unfortunately, physical skills deteriorate when they are not used, particularly the refinements of gain and timing. This means that a formerly experienced operator who has been monitoring an automated process may now be an inexeperienced one. Not only are the operator’s skills declining, but the situations when the operator will be called upon are by their very nature the most demanding ones where something is deemed to be going wrong. Thus what we really need in such a situation is a more, not a lesser skilled operator! To generate successful strategies for unusual situtations, an operator also needs good understanding of the process under control, and the current state of the system. The former understanding develops most effectively through use and feedback (which the operator may no longer be getting the regular opportunity for), the latter takes some time to assimilate.

Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser. I've never even _heard_ of JSMin.

Work on the biggest, most frequently used problems you can find, and create the largest net impact. Don’t give the customer what they ask for; understand them, and revolutionize their world. Developers should create a Google Design Document (a fairly minimal, but structured design doc), explaining the project, what goals it hopes to achieve, and explains why it can’t be done in other ways. This document should be circulated with stakeholders, to get early feedback before the project gets underway. The written record is essential, as it assures there is a clear and agreed understanding of when the project is a success and how it aims to get there. At all phases of the project, critical design elements for larger components should be concisely explained and captured in a design document. Innovate in leapfrogs. It’s more important to finish and deploy a leapfrog than to attempt perfection. There is no perfection. Instead be flexible, and plan to constantly reinvent at every level of the stack. Deliver working software as soon as is reasonably possible, and no sooner. “Dogfood” projects internally before they are shipped externally. Make sure products meet high quality standards before shipping. The quality of the product is more important than the time it takes to achieve it. ]]> agile architecture google scrum development coding projects project-management design https://pinboard.in/ https://pinboard.in/u:jm/b:a6046dfadf0d/ 2019-07-25T09:28:24+00:00 https://twitter.com/ItsTheShadsy/status/1151868012707962881 jm don-hopkins games history the-sims design romance 1990s https://pinboard.in/ https://pinboard.in/u:jm/b:b0a787e27996/ 2019-06-06T09:33:02+00:00 https://nyc.streetsblog.org/2019/06/03/op-ed-breaking-down-barriers-to-disabled-cyclists/ jmAccording to a recent study by Wheels for Well-being, a British organization of disabled cyclists, 15 percent of people with disabilities cycle, compared with 18 percent of the general population. Moreover, two-thirds of cyclists with disabilities find cycling easier than walking, the group says. Clearly, bikes are not just a mode of transit, but function as mobility devices for many disabled people.

We failed because we were naive enough to believe everyone had the same goals we did. We failed because we underestimated greed. We failed because we didn’t pay attention to history. We failed because our definition of we wasn’t big enough. We designed and built platforms that undermined democracy across the world.

Instead, Juicero spent $120M over two years to build a complex supply chain and perfectly engineered product that is too expensive for their target demographic. Imagine a world where Juicero raised only $10M and built a product subject to significant constraints. Maybe the Press wouldn’t be so perfectly engineered but it might have a fewer features and cost a fraction of the original $699. Or maybe with a more iterative approach, they would have quickly found that customers vary greatly in their juice consumption patterns, and would have chosen a per-pack pricing model rather than one-size-fits-all $35/week subscription.

But if you actually move around town like a normal person, your town as a whole is much more dangerous.” This is the opposite of what traffic engineers (and home buyers) have thought for decades. And it’s just the beginning of what we’re now starting to understand about the relative advantages of going back to the way we designed communities a century ago. Marshall and Garrick took the same group of California cities and also examined all their minutely classified street networks for the amount of driving associated with them. On average, they found, people who live in more sparse, tree-like communities drive about 18 percent more than people who live in dense grids. And that’s a conservative calculation.

And those differences are needed if we are to put the flowering of internet genius to use actually helping humanity with its many terrifying and seemingly intractable problems. ]]> best-practices sensitivity culture design silicon-valley youth privilege facebook https://pinboard.in/ https://pinboard.in/u:jm/b:4d86836aae34/ 2014-11-23T23:28:29+00:00 http://www.beerlabelizer.com/ jm beer labels generator flash design bottling https://pinboard.in/ https://pinboard.in/u:jm/b:c4caa7b941ca/ 2014-09-09T08:54:25+00:00 http://bldgblog.blogspot.ie/2014/09/procedural-brutalism.html jma few GIFs of procedurally generated architecture by a game developer named Cedric, built using Unity.

Not the least of these was that, as of a few months ago, trying to debug the kernel from the boot line would cause the system to crash. This was because of Systemd's voracious logging and the fact that Systemd responds to the "debug" flag on the kernel boot line -- a flag meant for the kernel, not anything else. That, straight up, is a bug. However, the Systemd developers didn't see it that way and actively fought with those experiencing the problem. Add the fact that one of the Systemd developers was banned by Linus Torvalds for poor attitude and bad design and another was responsible for causing significant issues with Linux audio support, but blamed the problem on everything else but his software, and you have a bad situation on your hands. There's no shortage of egos in the open source development world. There's no shortage of new ideas and veteran developers and administrators pooh-poohing something new simply because it's new. But there are also 45 years of history behind Unix and extremely good reasons it's still flourishing. Tools designed like Systemd do not fit the Linux mold, to their own detriment. Systemd's design has more in common with Windows than with Unix -- down to the binary logging. The link re systemd consuming the "debug" kernel boot arg is a canonical example of inflexible coders refusing to fix their own bugs.

The Netherlands has many excellent examples, but you have to be very selective about what serves as a model. Cyclists fare best where their interactions with motor vehicles are limited and controlled. They fare best where infrastructure ensures that minor mistakes do not result in injuries. Anywhere that we rely upon everyone behaving perfectly but where we do not protect the most vulnerable, there will be injuries. Good design takes human nature into account and removes the causes of danger from those who are most vulnerable. via Tony Finch]]> cycling design junctions shared-space dutch holland roads safety crashes https://pinboard.in/ https://pinboard.in/u:jm/b:810ac264dd38/ 2014-03-25T10:26:55+00:00 http://arnon.me/2014/03/services-microservices-nanoservices/ jm architecture antipatterns nanoservices microservices soa services design esb https://pinboard.in/ https://pinboard.in/u:jm/b:a19528e98dbf/ 2014-03-21T10:48:36+00:00 http://designtaxi.com/news/364536/A-Look-At-Airbnb-s-Irish-Pub-Inspired-Office-In-Dublin/#.Uyvx5Zh4cTN.twitter jm airbnb design offices work pubs ireland dublin https://pinboard.in/ https://pinboard.in/u:jm/b:5353b0377a51/ 2014-03-13T16:41:51+00:00 http://blog.johnryding.com/post/78544969349/how-to-reconnect-web-sockets-in-a-realtime-web-app jm exponential-backoff backoff retries reliability web-services http networking internet coding design https://pinboard.in/ https://pinboard.in/u:jm/b:f3677453107a/ 2014-02-23T22:14:44+00:00 http://jpkoning.blogspot.ie/2012/10/data-visualization-breaking-down.html jm economist graphs dataviz charts design ui https://pinboard.in/ https://pinboard.in/u:jm/b:3e3d6a192060/ 2013-10-10T14:07:50+00:00 http://tla2012.loria.fr/contributed/newcombe-slides.pdf jm tla+ pluscal tlc formal-methods simulation proving aws amazon architecture design https://pinboard.in/ https://pinboard.in/u:jm/b:897973b787e0/ 2013-07-27T17:33:29+00:00 http://sockpuppet.org/blog/2013/07/22/applied-practical-cryptography/ jmECC is going to replace RSA within the next 10 years.

Upon a master failure, we failover the slave as the new master and either bring up a new slave or reuse the old master as the new slave. We rely on ZooKeeper to make this as quick as possible. Each master Redis instance (and slave instance) is configured to write to AOF on Amazon EBS. This ensures that if the Redis instances terminate unexpectedly then the loss of data is limited to 1 second of updates. The slave Redis instances also perform BGsave hourly which is then loaded to a more permanent store (Amazon S3). This copy is also used by Map Reduce jobs for analytics. As a production system, we need many failure modes to guard ourselves. As mentioned, if the master host is down, we will manually failover to slave. If a single master Redis instance reboots, monit restart restores from AOF, implying a 1 second window of data loss on the shards on that instance. If the slave host goes down, we bring up a replacement. If a single slave Redis instance goes down, we rely on monit to restart using the AOF data. Because we may encounter AOF or BGsave file corruption, we BGSave and copy hourly backups to S3. Note that large file sizes can cause BGsave induced delays but in our cluster this is mitigated by smaller Redis data due to the sharding scheme. ]]> graph redis architecture ha high-availability design redundancy sharding https://pinboard.in/ https://pinboard.in/u:jm/b:78c92555c7b0/ 2013-05-16T15:43:40+00:00 http://www.oracle.com/technetwork/products/berkeleydb/learnmore/bdb-je-architecture-whitepaper-366830.pdf jm bdb-je java berkeley-db bdb design databases pdf white-papers trees https://pinboard.in/ https://pinboard.in/u:jm/b:92793f758cdc/ 2013-05-15T09:06:28+00:00 http://sweng.the-davies.net/Home/rustys-api-design-manifesto jm In the Linux Kernel community Rusty Russell came up with a API rating scheme to help us determine if our API is sensible, or not.  It's a rating from -10 to 10, where 10 is perfect is -10 is hell. Unfortunately there are too many examples at the wrong end of the scale. ]]> rusty-russell quality coding kernel linux apis design code-reviews code https://pinboard.in/ https://pinboard.in/u:jm/b:af2d8a163fb9/ 2013-03-29T11:31:40+00:00 http://nerds.airbnb.com/introducing-chronos jmChronos is our replacement for cron.

Thus by default, Chronos executes SH (on most systems BASH) scripts. Chronos can be used to interact with systems such as Hadoop (incl. EMR), even if the mesos slaves on which execution happens do not have Hadoop installed. Included wrapper scripts allow transfering files and executing them on a remote machine in the background and using asynchroneous callbacks to notify Chronos of job completion or failures. ]]> cron scheduling mesos stacks design airbnb chronos fault-tolerance distcomp distributed-computing scripts jobs https://pinboard.in/ https://pinboard.in/u:jm/b:ed1cc2afd7bc/ 2013-03-27T13:18:35+00:00 http://www.slideshare.net/Wolfr/design-for-developersonlineversionlong jm ui interface typography css design web slides https://pinboard.in/ https://pinboard.in/u:jm/b:6b75d4b1efcd/
