    1. How Much Does it Cost to Hire App Developers in 2023?

      One of the most significant factors in determining the cost of hiring an app developer is the expected output. So want to know the cost of Hire App Cost Developers? In this, Blog we have explained the how much does it Cost to Hire an App Developers.https://bit.ly/3AKLsfP

    1. Second, the range of the function must be efficiently computable, and it must be efficiently computable by you.

      taking too long to compute if a user is a good fit is the same as not being able to.

    1. How Startups Can Reduce Mobile App Development Cost? In today’s business climate, developing a high-quality mobile app can be expensive. Fortunately, there are some things you can do to reduce the cost of developing the app. Here, we have some of the trendy ways how to reduce app development costs. https://bit.ly/3B4CURp

    1. Dr. Miho Ohsaki re-examined workshe and her group had previously published and confirmed that the results are indeed meaningless in the sensedescribed in this work (Ohsaki et al., 2002). She has subsequently been able to redefine the clustering subroutine inher work to allow more meaningful pattern discovery (Ohsaki et al., 2003)

      Look into what Dr. Miho Ohsaki changed about the clustering subroutine in her work and how it allowed for "more meaningful pattern discovery"

    1. A quick and dirty guide to choosing "slow carbs" (low GLI) and "fast carbs" (high GLI). Purportedly, insulin spikes (from high GLI foods) and prevent amino acids from entering the blood brain barrier. Need to fact-check this

    1. Statistical heterogeneity is the term given to differences in the effects of interventions and comesabout because of clinical and/or methodological differences between studies (ie it is a consequenceof clinical and/or methodological heterogeneity). Although some variation in the effects ofinterventions between studies will always exist, whether this variation is greater than what isexpected by chance alone needs to be determined.

      If the statistical heterogeneity is larger that what's expected by chance alone, then what does that imply? That there's either clinical or methodological heterogeneity within the pooled studies.

      What's the impact of the presence of clinical heterogeneity? The statistical heterogeneity (variation of effects/results of interventions) becomes greater than what's expected by chance alone

      What's happens if methodological heterogeneity is present? The statistical heterogeneity (variation of effects/results of interventions) becomes greater than what's expected by chance alone

    1. Multimodal Learning Through Media:What the Research Says

      A white paper written by Metiri Group commissioned by Cisco in 2008. I came here to fact check some claims on this YT video about a "Feynman Technique 2.0".

      The claims were that

      1. direct hands-on experience in unimodal learning is (on average) inferior to multi-modal learning that wasn't hand-on. viz., for "basic concepts", a more abstract learning model is better

      2. "Once you get into higher-order concepts then hand-on experience is better"

      Page 13 was displayed while making these claims.

      These claims still need to be verified.

    1. So when configuring Capybara, I'm using ignore_default_browser_options, and only re-use this DEFAULT_OPTIONS and exclude the key I don't want Capybara::Cuprite::Driver.new( app, { ignore_default_browser_options: true, window_size: [1200, 800], browser_options: { 'no-sandbox': nil }.merge(Ferrum::Browser::Options::Chrome::DEFAULT_OPTIONS.except( "disable-features", "disable-translate", "headless" )), headless: false, } )

    1. Until now, we had a lot of code. Although we were using a plugin to help with boilerplate code, ready endpoints, and webpages for sign in/sign up management, a lot of adaptations were necessary. This is when Doorkeeper comes to the rescue. It is not only an OAuth 2 provider for Rails but also a full OAuth 2 suite for Ruby and related frameworks (Sinatra, Devise, MongoDB, support for JWT, and more).
    1. Currently Xournal++ does not have shortcuts/keybindings configurable in the preferences. However you can write your custom plugin to achieve exactly that.

      Must learn (and install) Lua (version >=5.3) to make custom shortcuts for Xournal++ via personally made plugins.

    1. Computers can only deal with well-structured problems

      ie, "well-defined problems" in John Vervaeke's language. Cultivation of wisdom, per Vervaeke, is developing the capacity to navigate a ill-defined problem space, and realize (ie, recognize, and make real) what is relevant to resolving the situation.

      Examples of ill-defined problems: - how to take good notes? - how to tell a funny joke? - how to go on a successful 1st date? - how to be a good friend?

      May relate to Shapiro's "role theory". Needs further research

    2. The paradox of information systems[edit] Drummond suggests in her paper in 2008 that computer-based information systems can undermine or even destroy the organisation that they were meant to support, and it is precisely what makes them useful that makes them destructive – a phenomenon encapsulated by the Icarus Paradox.[9] For examples, a defence communication system is designed to improve efficiency by eliminating the need for meetings between military commanders who can now simply use the system to brief one another or answer to a higher authority. However, this new system becomes destructive precisely because the commanders no longer need to meet face-to-face, which consequently weakened mutual trust, thus undermining the organisation.[10] Ultimately, computer-based systems are reliable and efficient only to a point. For more complex tasks, it is recommended for organisations to focus on developing their workforce. A reason for the paradox is that rationality assumes that more is better, but intensification may be counter-productive.[11]

      From Wikipedia page on Icarus Paradox. Example of architectural design/technical debt leading to an "interest rate" that eventually collapsed the organization. How can one "pay down the principle" and not just the "compound interest"? What does that look like for this scenario? More invest in workforce retraining?

      Humans are complex, adaptive systems. Machines have a long history of being complicated, efficient (but not robust) systems. Is there a way to bridge this gap? What does an antifragile system of machines look like? Supervised learning? How do we ensure we don't fall prey to the oracle problem?

    1. What Is a Blockchain Oracle? A blockchain oracle is a secure piece of middleware that facilitates communication between blockchains and any off-chain system, including data providers, web APIs, enterprise backends, cloud providers, IoT devices, e-signatures, payment systems, other blockchains, and more. Oracles take on several key functions: Listen – monitor the blockchain network to check for any incoming user or smart contract requests for off-chain data. Extract – fetch data from one or multiple external systems such as off-chain APIs hosted on third-party web servers. Format – format data retrieved from external APIs into a blockchain readable format (input) and/or making blockchain data compatible with an external API (output). Validate – generate a cryptographic proof attesting to the performance of an oracle service using any combination of data signing, blockchain transaction signing, TLS signatures, Trusted Execution Environment (TEE) attestations, or zero-knowledge proofs. Compute – perform some type of secure off-chain computation for the smart contract, such as calculating a median from multiple oracle submissions or generating a verifiable random number for a gaming application. Broadcast – sign and broadcast a transaction on the blockchain in order to send data and any corresponding proof on-chain for consumption by the smart contract. Output (optional) –  send data to an external system upon the execution of a smart contract, such as relaying payment instructions to a traditional payment network or triggering actions from a cyber-physical system.

      Seems related to the paradox of information systems. Add to Anki deck

    1. From the Introduction to Ed25519, there are some speed benefits, and some security benefits. One of the more interesting security benefits is that it is immune to several side channel attacks: No secret array indices. The software never reads or writes data from secret addresses in RAM; the pattern of addresses is completely predictable. The software is therefore immune to cache-timing attacks, hyperthreading attacks, and other side-channel attacks that rely on leakage of addresses through the CPU cache. No secret branch conditions. The software never performs conditional branches based on secret data; the pattern of jumps is completely predictable. The software is therefore immune to side-channel attacks that rely on leakage of information through the branch-prediction unit. For comparison, there have been several real-world cache-timing attacks demonstrated on various algorithms. http://en.wikipedia.org/wiki/Timing_attack

      Further arguments that Ed25519 is less vulnerable to - cache-timing attacks - hyperthreading attacks - other side-channel attacks that rely on leakage of addresses through CPU cache Also boasts - no secret branch conditions (no conditional branches based on secret data since pattern of jumps is predictable)

      Predicable because underlying process that generated it isn't a black box?

      Could ML (esp. NN, and CNN) be a parallel? Powerful in applications but huge risk given uncertainty of underlying mechanism?

      Need to read papers on this

    1. I work primarily on Windows, but I support my kids who primarily use Mac for their college education. I have used DT on Mac, IPOS, IOS for about a year. On Windows, I have been using Kinook’s UltraRecall (UR) for the past 15 years. It is both a knowledge outliner and document manager. Built on top of a sql lite database. You can use just life DT and way way more. Of course, there is no mobile companion for UR. The MS Windows echo system in this regard is at least 12 years behind.

      Reference for UltraRecall (UR) being the most DEVONthink like Windows alternative. No mobile companion for UR. Look into this being paired with Obsidian

    1. I also think being able to self-host and export parts of your data to share with others would be great.

      This might be achievable through Holochain application framework. One promising project built on Holochain is Neighbourhoods. Their "Social-Sensemaker Architecture" across "neighbourhoods" is intriguing

    1. Samuel Bowles and Herbert Gintis intheir classic Schooling in Capitalist America

      Bowles and Gintis apparently make an argument in Schooling in Capitalist America that changes in education in the late 1800s/early 1900s served the ends of capitalists rather than the people.

    1. Now I can take an article from almost anywhere on my phone (reading services like Pocket, my feed readers, or even articles within the browser themselves), click share, choose “URL Forwarder” from the top of the list, select “Hypothesize” and the piece I want to annotate magically opens up with Hypothes.is ready to go in my default browser. Huzzah!

      Useful how-to for setting up Hypothes.is for mobile use on Android. Confirmed that this works on Brave mobile browser

    1. I've been told since the first day I started working at the Division of Hospital Medicine at @UCSF that my work doesn't bring in $ to cover my salary. It's a narrative of manufactured scarcity, a common tactic in capitalism. The CEO is making $1.85 million plus bonuses.

      A Hospitalist’s economic value is in what we *save* the system in terms of quality-driven care and patient throughput (DC/unit time), not in how much we bring in through profees. Because of how the system is structured, you’ll only see our value when we aren’t there.

      This sounds a lot like hospitalists fall under David Graeber's thesis in Bullshit Jobs that the more necessary and useful you are the less you're likely to get paid and be valued.

      I suspect the ability to track an employees' direct level of productivity also fits into this thesis. One can track the productivity of an Amazon warehouse worker or driver, but it's much more difficult to track the CEOs direct productivity.

      Suggested by

      "Relation in Art" by Vernon Blake (1925), because it put art criticism on a quasi-scientific footing, articulated what was great about the art of all epochs (including the Greeks), and intelligently criticised the decline of art in the 20th century.

    1. The novelist and screenwriter Raymond Chandler said he avoided reading books written by someone who didn’t “take the pains” to write out the words. (It used to be common for writers to dictate into a recorder then have an assistant transcribe those words.) “You have to have that mechanical resistance,” Chandler wrote in a 1949 letter to actor/writer Alex Barris. “When you have to use your energy to put those words down, you are more apt to make them count.”
    2. If you can’t talk yourself into using your energy to write or type something out, it’s probably not worth capturing.

      Being willing to capture an idea by spending the time writing it out in full is an incredibly strong indicator that it is actually worth capturing. Often those who use cut and paste or other digital means for their note capture will over-collect because the barrier is low and simple.

      More often than not, if one doesn't have some sort of barrier for capturing notes, they will become a burden and ultimately a scrap heap of generally useless ideas.

      In the end, experience will eventually dictate one's practice as, over time, one will develop an internal gut feeling of what is really worth collecting and what isn't. Don't let your not having this at the beginning deter you. Collect and process and over time, you'll balance out what is useful.

    1. There are two situations where an init-like process would be helpful for the container.
    2. highly recommended that the resulting image be just one concern per container; predominantly this means just one process per container, so there is no need for a full init system

      container images: whether to use full init process: implied here: don't need to if only using for single process (which doesn't fork, etc.)

    3. Try to make the Dockerfile easy to understand/read.
    4. For example, if using apt to install the main program for the image, be sure to pin it to a specific version (ex: ... apt-get install -y my-package=0.1.0 ...)
    5. Rebuilding the same Dockerfile should result in the same version of the image being packaged, even if the second build happens several versions later, or the build should fail outright, such that an inadvertent rebuild of a Dockerfile tagged as 0.1.0 doesn't end up containing 0.2.3.
    6. Version bumps and security fixes should be attended to in a timely manner.
    7. If you do not represent upstream and upstream becomes interested in maintaining the image, steps should be taken to ensure a smooth transition of image maintainership over to upstream.
    1. Unfortunately most init systems don't do this correctly within Docker since they're built for hardware shutdowns instead. This causes processes to be hard killed with SIGKILL, which doesn't give them a chance to correctly deinitialize things.
    1. Zombie processes should not be confused with orphan processes: an orphan process is a process that is still executing, but whose parent has died. When the parent dies, the orphaned child process is adopted by init (process ID 1). When orphan processes die, they do not remain as zombie processes; instead, they are waited on by init.
    1. To check whether the music symbol ♫ is being displayed in a string (if it is not being displayed on some devices), you can try measuring the string width; if width == 0 then the symbol is absent.
    2. I want to check if the String I am about to display can be displayed by my custom font.
    3. I can't find a method to check if my Typeface can display a particular String though.
    1. While there are many great answers regarding the "glyph not found" glyph, that won't help you actually detect it, as the text string in code will still have the character regardless of the font used to render it.
    2. Then don’t use the phrase “replacement character”, because a) it’s not a character at all, and b) it’s specifically not the character with the Unicode name REPLACEMENT CHARACTER, and c) people easily get confused with issues like this.
    3. it does not have a fixed glyph, though fonts that contain it tend to use very similar glyphs
    1. Since the replacement is the same for all errors this makes it impossible to recover the original character. A better (but harder to implement) design is to preserve the original bytes, including the error, and only convert to the replacement when displaying the text. This will allow the text editor to save the original byte sequence, while still showing the error indicator to the user.
    1. To become an international superhero, fork this gist, make a shell-runable node.js application font-to-regexp.js that just takes your font file(s?) on the command line, invokes ttx for you on it(them), loads the result with jsdom, runs fontRange on it and prints the regexp to stdout, instead of doing the above steps manually. Oh, and brag about it in the comments here, of course, so other people find it too!
    1. Lucky for us, it’s super easy to use subdomains in development nowadays. http://lvh.me is a free service that resolves itself along with all subdomains to localhost.
    1. Can you refactor your code so that instead of returning from within the transaction block you set a variable and then return outside of the block?
    2. I think I had expected that existing rails developers would discover this problem in existing code through the deprecation warning to avoid a nasty surprise. I'm worried about my future kids learning Rails and writing perfectly looking Ruby code just to learn the hard way that return is sometimes a nono! Jokes aside, I think that no one expected that the deprecation will turn into silent rollbacks. This is a very controversial change, pretty much everyone taking part in the discussion on the deprecation PR raised some concerns about the potential consequences of this change. The only thing that was making it easier to swallow was the promise of making it clear to the user by throwing an exception after the rollback.

    1. Most men's notes are useless stuff to others, useless even to them-selves with the passage of time, and useless especially because ofchaotic arrangement.
    1. Just as a breadcrumb here for future readers (I found this thread when I was searching), it seems Cuprite has support for non-headless now (via Ferrum). headless: false in the options does the trick. And thanks for your work on Cuprite.
    1. The problem is that the caller may write yield instead of block.call. The code I have given is possible caller's code. Extended method definition in my library can be simplified to my code above. Client provides block passed to define_method (body of a method), so he/she can write there anything. Especially yield. I can write in documentation that yield simply does not work, but I am trying to avoid that, and make my library 100% compatible with Ruby (alow to use any language syntax, not only a subset).

      An understandable concern/desire: compatibility

      Added new tag for this: allowing full syntax to be used, not just subset

    2. This breaks the TIMTOWTDI rule
    1. I'm afraid you missed the joke ;-) While you believe spaces are required on both sides of an em dash, there is no consensus on this point. For example, most (but not all) American authorities say /no/ spaces should be used. That's the joke. In writing a line about "only one way to do it", I used a device (em dash) for which at least two ways to do it (with spaces, without spaces) are commonly used, neither of which is obvious -- and deliberately picked a third way just to rub it in. This will never change ;-)
    1. “The one inhibition I felt using AnswerGarden [was] knowing that the experts were typically busy and workingon projects more important than my little application programs....

      So rather than distributing input over time, why not have a one-day deep dive with everyone (luncheon retreat)?

    2. ix users were “heavy” users, accounting for 61% of the totalsessions. Heavy users often kept Answer Garden running in an iconifiedstate between uses. One heavy user reported:

      Just like any social media site.

      So far, Answer Garden seems better used and similarly in demand as Piazza.

    4. Each user and each expert has incentives to work separately toward theconstruction of such a Garden. The users get to find answers, and expertscan rid themselves of commonly asked questions.

      This may help me with my own research needs to crowdsource peer review and create "living peer reviews."

    5. Several important considerations behind Answer Garden include:

      This feels entirely different from modern organizational memory aids like Almanac (https://almanac.io/)!

    6. ngineerschose not to go to the channel of the highest quality for technical informa-tion, but rather to go to the channel of highest accessibility (i.e., lowestpsychological cost). Allen [1977] argued that the psychological cost was inthe potential lack of reciprocity between giving and obtaining informationand in the status implications of admitting ignorance.

      My last company had a page in their wiki with acronyms and downloadable Excel spreadsheets!

    7. information technology can support organizational memory in twoways, either by making recorded knowledge retrievable or by makingindividuals with knowledge accessible

      I tried to do this in my last role as a lab manager and we have a PhD student spreadsheet I added variables to for this specific purpose.

      Check it out here: https://docs.google.com/spreadsheets/d/10qMAJjYc7fTGLLSmvrD7pk8v1KeHJYLC47JMBvqxG8A/edit?usp=sharing

    1. Out of this friction of competing ideas can comethe sort of improvisational sparks necessary for igniting organizational innovation.Thus large organizations, reflectively structured, are perhaps particularly well posi-tioned to be highly innovative and to deal with discontinuitie

      I agree! But do you expect MBAs to succeed in this area? Reorganizing companies to form such effective subunits and to incentivize the deeper though that innovation requires will be difficult on the shorter timelines upon which businesses operate.

    2. Reliance on formal descriptions of work, explicit syllabuses for learning about it,and canonical groups to carry it out immediately set organizations at a disadvantage.This approach, as we have noted, can simply blind management to the practices andcommunities that actually make things happ

      How can we learn and teach better in a grad school context with this in mind? Implications?

    3. The inadequacies of this corporation's directive approach actually make a rep'swork more difficult to accomplish and thus perversely demands more, not fewer,improvisational skill

      Anyone have stories about this in their employment history?

    4. 41

      Page note: How does this relate to lab notebooks and their use in offering a window into lab practices and culture?

    5. he ways people actuallywork usually differ fundamentally from the ways organizations describe that work in manuals,training programs, organizational charts, and job descriptions.

      Hidden curriculum -> Hidden duties and processees

    1. Bryan Caplan has made a spirited defense of school as signaling in his book, The Case Against Education. He argues that what is taught in school isn’t particularly useful on the job. Instead, schooling provides a mechanism for figuring out who has the talent, ambition and obedience to learn on the job successfully.
    1. Note that one extra type that is accepted by convention is the Boolean type, which represents both the TrueClass and FalseClass types.
    2. Note: For keyword parameters, use @param, not @option.

      I sure was looking for @option (knowing already about @param) and assuming/expecting that (if it exists) it would totally be the right thing to use for documenting keyword parameters. So I was quite surprised to see this much-needed warning (for me and others like me who came here expecting/assuming the same thing).
