They discuss the need for requirements in every software project and provide recommendations on how to gather, analyze, validate, and manage those requirements. Candase and Karl offer in-depth perspectives on a range of topics, including how to elicit requirements, speak with users, get to the source of the business or user goal, and create requirement sets, models, prototypes, and baselines. Finally, they look at specifications you can use, and how to validate, test, and verify them. Brought to you by IEEE Computer Society and IEEE Software magazine. Full Article
ui SE Radio 630: Luis Rodríguez on the SSH Backdoor Attack By se-radio.net Published On :: Thu, 22 Aug 2024 20:59:00 +0000 Luis Rodríguez, CTO of Xygeni.io, joins host Robert Blumen for a discussion of the recently thwarted attempt to insert a backdoor in the SSH (Secure Shell) daemon. OpenSSH is a popular implementation of the protocol used in major Linux distributions for authentication over a network. Luis describes how a backdoor in a supporting library was recently discovered and removed before the package was published to stable releases of the Linux distros. The conversation explores the mechanism of the attack through modifying a function table in the runtime; how the attack was inserted during the build; how the attack was carefully staged in a series of modifications to the lz compression library; the nature of “Jia Tan,” the entity who committed the changes to the open source project; social engineering that the entity used to gain the trust of the open source community; what forensics indicates about the location of the entity; hypotheses about whether criminal or state actors backed the entity; how the attack was detected; implications for other open source projects; why traditional methods for detecting exploits would not have helped find this; and lessons learned by the community.

ui Be Unique And Use RSS Guid Like Everybody Else By www.rssboard.org Published On :: Mon, 10 Jul 2023 22:30:01 -0400 Winter scenes: Snowflakes by Theodor HorydczakIf you publish an RSS feed, you should do a solid for the developers of RSS readers by including a guid in each item. The guid's job is to be a unique identifier that helps software downloading your feed decide whether it has seen that item before. Here's the guid for an item on the arts and technology blog Laughing Squid:<guid isPermaLink="false">https://laughingsquid.com/?p=914660</guid>No other item on Laughing Squid will ever have this guid value. It's a URL that loads a blog post with the title Playful Elephant Pretends to Eat Woman's Hat. If you load the guid's URL https://laughingsquid.com/?p=914660, it redirects to the permanent link of the post. Because the guid is not the permanent link, there's an isPermaLink attribute with a value of false.Most guid values in RSS feeds are the permanent link of the item, as in this example from the world news site Semafor:<guid>https://www.semafor.com/article/07/07/2023/us-jobs-data-what-experts-make-of-the-new-numbers</guid>A drawback of using the permalink is that if any part of the URL changes -- such as the title text or the domain name -- the guid changes and RSS readers will think this is a new item to show the feed's subscribers, when it's actually a repeat.A guid doesn't have to be a URL. It can be any string that the feed publisher has chosen to be unique. Here's the guid from the RSS Advisory Board's feed for this blog post:<guid isPermaLink="false">tag:rssboard.org,2006:weblog.217</guid>Our guid follows the TAG URI scheme, a simple way to assure uniqueness by putting these five components together in this order:The text "tag"A domain owned by the feed providerA year the provider owned that domainA short name for the feed different from any other feed on the siteThe internal ID number of the post There's different punctuation between each component. The year 2006 was when the board began using the domain rssboard.org. No one else used that domain that year, so any feed reader that stores "tag:rssboard.org,2006:weblog.217" as this item's guid should never encounter that value in any other item on any other feed.To see how RSS 2.0 feeds are using guid, several thousand feeds were downloaded this evening from an RSS aggregator that publicly shares the OPML subscription lists of its users.CategoryTotalPercentageTotal number of feeds4,954--Feed using guid4,77796.4%Feeds using non-permalinks in guid75215.2%The term guid means "globally unique identifier," but RSS 2.0 does not require global uniqueness in guids. Because the TAG URI scheme does a good job of serving that purpose, Blogger, Flickr, MetaFilter, SoundCloud and The Register are among the sites using it in their feeds. Full Article announcements

ui The Benefits of Educational Quizzes and Tests By careertechtesting.blogspot.com Published On :: Mon, 06 Jan 2014 18:08:00 +0000 John Kleeman shared on Questionmark's Blog the ten benefits of quizzes and tests in educational practice as proposed by psychology experts Henry L. Roediger III, Adam L. Putnam and Megan A. Smith in a recent paper, “Ten Benefits of Testing and Their Applications to Educational Practice”. Here is John's summary and understanding of the paper: 1. Retrieval aids later retention. There is clear evidence from psychological experiments that practicing retrieval of something after learning it, for instance by taking a quiz or test, makes you more likely to retain it for the long term. 2. Testing identifies gaps in knowledge. 3. Testing causes students to learn more from the next study episode. Essentially it reduces forgetting which makes the next related study area more productive. 4. Testing produces better organization of knowledge by helping the brain organize material in clusters to allow better retrieval. 5. Testing improves transfer of knowledge to new contexts. There are several experiments referenced in the paper where tests and quizzes help transfer and application of knowledge. 6. Testing can facilitate retrieval of material that was not tested. Surprisingly there are circumstances where quizzes or tests, particularly if delayed, can help people retrieve/retain information that was related to that asked but not actually asked in the questions. 7. Testing improves metacognitive monitoring – by giving students scores or self-assessments, they can better predict their knowledge and be more confident about what they know and what they need to know. 8. Testing prevents interference from prior material when learning new material. If you have a test after learning one set of material before learning another set of material, it can make it less likely that the second session will 9. Testing provides feedback to instructors and lets them know what is learned or what is not. 10. Frequent testing encourages students to study. Having frequent quizzes and tests motivates study and reduces procrastination. You can see their paper “Ten Benefits of Testing and Their Applications to Educational Practice” in Psychology of Learning and Motivation, Vol 55. It’s also available for download on Professor Roediger’s publications page, in the list of papers from 2011, at http://psych.wustl.edu/memory/publications/.

ui The Educator's Guide to Hashtags By careertechtesting.blogspot.com Published On :: Wed, 13 Jan 2016 18:26:00 +0000 Follow us on Twitter! @CareerTechTest Whether you're a social media novice or not, hashtags may seem confusing and inessential. These short links (hashtags) preceded by the pound sign (#) are integral to the way we communicate online and it's important to know how to use them. Can hashtags be fun? Absolutely! On Twitter, the pound sign (or hash) turns any word or group of words into a searchable link. This allows you to organize content and track discussion topics based on those keywords. So, if you want to post about the NFL Super Bowl, you would include #SuperBowl in your tweet to join the conversation (or simply search for the hashtag to follow the discussion). Clicking on a hashtag will allow you to see all the posts that mention the subject in real time. I also recommend using a social media management platform, such as HooteSuite, TweetDeck, etc., where you can create columns with hashtag topics. I like the ability to monitor several discussions, i.e. #edchat, #lrnchat, #careerteched, at once and all on the same screen. I've created a list of popular educational hashtags and tried to categorize them for you (see below). It definitely isn't all inclusive, but it's a good starting point and I hope you will share any new educational hashtags you find interesting and helpful! (Also, hashtags are now a staple to social media and their use has been extended to other social media platforms.)
