    1. instructional systems can function in coordination with other human performance improvement syste ms, such as knowledge management systems, incentive systems, organizational developme nt syste ms, and personnel selectio n syste ms.

      the systems can coexist with other aspects of human activity.

    2. instructio nal systems are some­ti mes referred to as training systenlS

      Not quite correct. But we are falling again on the issue of contextual definitions for instructional system. Maybe take a different approach where I use one definition.

      • training systems: when it primarily on skill development.
    3. educational systems when they focus more on generalized inte l­lectual development and personal compete nce.

      a system tailored for generalized cognitive skills/educational systems.

    4. a variety of forms, ranging fro m narrowly focused technical training courses to loosely structure d student-focused learning enviro nments, and exist in virtually any institution with the express purpose ofdeveloping human capacities. These include public schools, universities, miJitary organizations, business and industry, public service, and no n­profit organizations.

      There can be a "natural" vs. artificial system. To take control of the process, you would start with an analysis of the whole.

    5. An i11Stmctional system may be defined as an arrangement of r esources and p roce­dures used to facilitate learning.

      An arrangement, an organized approach, a set of resources and procedures.

    1. Your styles are scoped to the component. No more leakage, no more unpredictable cascade.
    2. It's fashionable to dislike CSS. There are lots of reasons why that's the case, but it boils down to this: CSS is unpredictable. If you've never had the experience of tweaking a style rule and accidentally breaking some layout that you thought was completely unrelated — usually when you're trying to ship — then you're either new at this or you're a much better programmer than the rest of us.
    3. It gets worse when you're working on a team. No-one dares touch styles authored by someone else, because it's often unclear what they're doing, what markup they apply to, and what disasters will unfold if you remove them. The consequence of all this is the append-only stylesheet. There's no way of knowing which code can safely be removed, so it's common to undo some existing style with another, more specific style — even on relatively small projects.

    1. Where these systems most notably differ is in their units of volume. A US fluid ounce (fl oz), about 29.6 millilitres (ml), is slightly larger than the imperial fluid ounce (about 28.4 ml). However, as there are 16 US fl oz to a US pint and 20 imp fl oz per imperial pint, the imperial pint is about 20% larger. The same is true of quarts, gallons, etc.; six US gallons are a little less than five imperial gallons.

    1. Heat and work have signs (positive or negative), and the sign of each depends on whether the system we are considering is gaining or losing energy. In this class, if a process makes the system gain energy, qqq and/or www are positive; if the process makes the system lose energy, qqq and/or www are negative. We can put this information into four formal statements: If heat flows into a system, qqq is positive. If heat flows out of a system, qqq is negative If the surroundings do work on the system, www is positive. If the system does work, www is negative.

      Heat and work have signs (positive or negative), and the sign of each depends on whether the system we are considering is gaining or losing energy. In this class, if a process makes the system gain energy, q and/or w are positive; if the process makes the system lose energy, q and/or w are negative. We can put this information into four formal statements:

      • If heat flows into a system, q is positive.
      • If heat flows out of a system, q is negative

    1. Cumulatively, these studies suggest that the potential influence of informal mentors on mobility may be most pronounced for those youth who are facing a disadvantage of some kind (family structure, income, etc.) and/or are a racial ethnic minority. Concerning the focus of the present study, this literature would suggest that informal mentoring may be more strongly associated with upward mobility for low-income youth than for middle-or higher-income youth for whom informal mentoring is

      Suggests a stronger influence on disadvantaged or racial ethnic minority youth

    2. Persistent immobility also disproves the idea of the U.S. being a land of equal opportunity. Since the term "the American Dream" was first coined in 1931, it has become a persistent cultural ethos, a wish list of sorts, with a consistent main tenet being the idea that each generation can achieve more than their parents (Samuel, 2012). Yet we know this tenet of the American Dream is no longer true: the chances that a child earnsmore than their parents has decreased in the past 40 years, especially for low-income families

      chances of earning more than parents has decreased in past 40yrs for low-income families

    1. This tightly controlled build environment is sometimes called a "holy build box". The Traveling Ruby project provides such a holy build box.
    1. Insight through making suggests that you’ll need to make simultaneous progress in theory-space and system-space to spot the new implications in their conjoined space. Effective system design requires insights drawn from serious contexts of use: you must constantly instantiate new theoretical ideas in new systems, then observe their impact in some serious context of use.

      Very powerful way of wording the implications of Insights through making and the need for serious contexts of use.

      You need to advance in theory-space as well as in system-space to spot the implications for their conjoined space.

      Pragmatically, you must constantly instantiate new theoretical ideas in the system, then observe the effects in some serious context of use.

    1. Programming languages and operating systems Stanford CoreNLP is written in Java; recent releases require Java 1.8+. You need to have Java installed to run CoreNLP. However, you can interact with CoreNLP via the command-line or its web service; many people use CoreNLP while writing their own code in Javascript, Python, or some other language. You can use Stanford CoreNLP from the command-line, via its original Java programmatic API, via the object-oriented simple API, via third party APIs for most major modern programming languages, or via a web service. It works on Linux, macOS, and Windows. License The full Stanford CoreNLP is licensed under the GNU General Public License v3 or later. More precisely, all the Stanford NLP code is GPL v2+, but CoreNLP uses some Apache-licensed libraries, and so our understanding is that the the composite is correctly licensed as v3+.
    1. This isn’t the first time Kerckhoffs’ Principle has come up. I specifically discussed it when talking about creating good, strong Master Passwords, when I said that we should use a system for coming up with Master Passwords that doesn’t lose its strength if the attacker knows the system that we used
    2. Kerckhoffs’ Principle states that you should assume that your adversary knows as much about the system you use as you do. This is why – despite what I may have said on April Fools Day last year – security experts are skeptical of security systems that hide the details of how they operate. They are particularly skeptical of systems that derive their security from keeping the details of how they work secret. I could go on at great length about why openness about the system improves security. Indeed, my first draft of this article did go on at great length.
    1. School for many people is a place to get fed, a place to feel safe, a place to get encouraged. It’s a place to be around people who share your desire to learn. Now they are cut off from that, and some of that can’t be duplicated easily online.

      Yes, this is a problem. However... Schools weren't designed to be a safegaurd against poor parenting, but they're treated that way, as if they're a place to escape the idiots they live with.

      Schools shouldn't tolerate this. Instead, they should intervene. They should bring in a third party, someone/an organization specifically designed to help kids who come from broken homes, to help heal how they live when school's not in session. Any measure less than this signals, to me, a school system that's not paying attention to their student's emotional needs, which are, I believe, key to ensuring the child thrives throughout their school years.

    1. Relational databases are designed around joins, and optimized to do them well. Unless you have a good reason not to use a normalized design, use a normalised design. jsonb and things like hstore are good for when you can't use a normalized data model, such as when the data model changes rapidly and is user defined. If you can model it relationally, model it relationally. If you can't, consider json etc.
    2. Joins are not expensive. Who said it to you? As basically the whole concept of relational databases revolve around joins (from a practical point of view), these product are very good at joining. The normal way of thinking is starting with properly normalized structures and going into fancy denormalizations and similar stuff when the performance really needs it on the reading side. JSON(B) and hstore (and EAV) are good for data with unknown structure.

    1. A website called Open Food Facts, run by mostly French volunteers, has started the herculean labour of creating an open database of packaged foods around the world and listing where they fit into on the Nova system.
    1. I use this to keep information about processes that were running at any time during last five days. These are 1-min snapshots so something might get lost but I think it is good enough for me. I want to have some data available when I discover there was a peak in resource usage (I use munin for that). I haven't found a better way to keep track of past processes (tried psacct).

    1. Indexes are a cornerstone of information retrieval, and the basis for today's modern search engines.
    2. This is known as collapsed forwarding.

      Proxies group a bunch of similar requests, before forwarding the request to app servers.

    3. four of the more important ones are caches, proxies, indexes and load balancers.

      Speeding data retrieval Or reducing latency

    4. benchmark different alternatives, understand how the system will fail, and have a solid plan for when failure happens.

      Managing Failure. Failing gracefully

    5. with the Flickr architecture each shard would need to be updated or searched (or a search service would need to be created to collate that metadata—which is in fact what they do).

      Search service for collating data spread out in shards.

    6. Finally, this separates future concerns, which would make it easier to troubleshoot and scale a problem like slow reads.

      Separation of concern (of components)

    7. Deconstructing a system into a set of complementary services decouples the operation of those pieces from one another. This abstraction helps establish clear relationships between the service, its underlying environment, and the consumers of that service. Creating these clear delineations can help isolate problems, but also allows each piece to scale independently of one another. This sort of service-oriented design for systems is very similar to object-oriented design for programming.

    1. It's not for beginners, but it's extremely flexible once you get a handle on things. If sticking to a system is hard for you, I highly recommend giving this system a try.

    1. it is certainly more creditable to cultivate the earth for the sustenance of man, than to be the confidant, and sometimes the accomplice, of his vices; which is v1_117the profession of a lawyer

      (Deleted in 1831). Percy Shelley had suffered negative rulings by the English court system and Mary seems to share his moral judgment on the legal profession. This skepticism will soon be reinforced in the novel by the court's harsh treatment of Justine Moritz.

    1. Now using sudo to work around the root account is not only pointless, it's also dangerous: at first glance rsyncuser looks like an ordinary unprivileged account. But as I've already explained, it would be very easy for an attacker to gain full root access if he had already gained rsyncuser access. So essentially, you now have an additional root account that doesn't look like a root account at all, which is not a good thing.
    1. It is possible to do a successful file system migration by using rsync as described in this article and updating the fstab and bootloader as described in Migrate installation to new hardware. This essentially provides a way to convert any root file system to another one.
    2. rsync provides a way to do a copy of all data in a file system while preserving as much information as possible, including the file system metadata. It is a procedure of data cloning on a file system level where source and destination file systems do not need to be of the same type. It can be used for backing up, file system migration or data recovery.
    1. I am familiar with using rsync to back up various files from my system but what is the best way to completely restore a machine.
    1. I run the script daily, early every morning, as a cron job to ensure that I never forget to perform my backups.
    2. There are many options for performing backups. Most Linux distributions are provided with one or more open source programs specially designed to perform backups. There are many commercial options available as well. But none of those directly met my needs so I decided to use basic Linux tools to do the job.
    1. CloneZilla works perfectly. It produces small image files, has integrity check and works fast. If you want to use third device as image repository you should choose device-image when creating image of the first disk and then image-device when you restore it to second disk. If you want to use only two disks - you should use device-device mode. Optionally you may want generate new UUIDs, SSH-key (if SSH server installed), and change hostname.
    1. While there are so many tools to backup your systems, I find this method super easy and convenient, at least to me. Also, this method is way better than disk cloning with dd command. Because It doesn’t matter if your hard drive is different size, or use different filesystem.

    1. Can I ask people to upvote my submission? No. Users should vote for a story because they personally find it intellectually interesting, not because someone has content to promote.
    1. Twitter offers two distinct benefits to engaging learners. First of all, it allows learners to respond to classroom discussions in a way that feels right for them, offering shy or introverted students a chance to participate in the class discussion without having to speak in a public forum. Secondly, it allows students to continue the conversation after class is completed, posting relevant links to course material, and reaching out to you (the educator) with additional thoughts or questions.

      The article explains how social media, student learning through digital experience, and Learning Management Systems can be beneficial to the learner/student. Article Rating: 3/5

    1. ATE introduced various kinds of lubrication pumps which can transfer liquids at high pressure without affecting its properties. Lubrication system helps to deliver a controlled amount of lubricant to multiple parts of the machine. ATE Group’s lubrication pumps have many benefits like reducing machinery and component maintenance cost, proper lubrication flow and increase productivity.

    1. Sen. Bernie Sanders, I-Vt., with his “Medicare for All” legislation—suggest Americans would enjoy a health care utopia if only the government took over.

      I feel there will be to much regulation to go through

    2. A “single-payer” health system is a government-controlled health care system. Government is the “single-payer.” In most versions of single-payer, most private health insurance is either outlawed or restricted, and most public health programs are absorbed into the single, national health insurance program.

      Explain the "Single-payer" system.

    1.  In Switzerland, which has a private universal health care system, only 25.9% waited at least 4 weeks.

      Switzerland system

    2. third of Americans reported they didn’t go to the doctor

      Then they must have died of some type of sickness

    3. The United States is the wealthiest nation

      Then why are so much debt

    4. by Blahous’s own estimates that single-payer would save Americans more than $2 trillion over a decade.

      That's impossible

    5. Funding for his plan is still being debated, but he has come up with multiple suggestions that could be passed.

      We are already into debt

    6. Medicare eligibility age would be lowered to 55, second year to 45, third year to 35, and fourth year everyone would be covered.

      If they were to pass it they would have to do this.

    7. You will not be able to keep the insurance you have

      There goes one flaw in doing that

    8. tudies show that costs would be between $25 Trillion and $32 Trillion over 10 years. YouGov/Economist Poll, April 2-4, 2017      $32 Trillion sounds like quite a high number.

      The government seems that they are afraid of doing it because they might go in debt.

    9. Removing the current system would a gigantic task.

      There risk with changing the system of the U.S.
