меня есть знакомый энтузиаст LLM, который также изучает верилог. Я попросил его написать инструкцию к упражнению с неким сенсором, который он интегрировал. Он разумеется сбросил это на LLM, я почитал и понял, что LLM нужно запретить как распостранение Экстази и "солей" среди молодежи. Точно так же как "дизайнерские наркотики" дают ощущение счастья и достижения без труда, сгенеренная LLM документация выглядит как реальная, вот только читателю она не поможет.</p><p>Что нужно читателю? Картинку как подцепить сенсор к плате, временную диаграмму сигналов которые от него выходят и пару слов про проблемы, которые у него возникнут (дребезг) и как их стоит решать. Так чтобы было достаточно информации, чтобы сесть и написать код на верилоге.</p><p>Что выдал LLM? Сначала пять абзацев мутного словестного описания что "изменения переключателей проходят некоторую последовательность, позволяющую определить направление", с галлюцинациями что движется и что неподвижно. Потом не имеющую отношения к задаче информацию, из каких материалов делаются эти сенсоры в разных странах мира, чтобы быть дешевыми для хоббистов и образовательных учреждений. Далее про разные способы решения проблемы дребезга, в том числе способы, не имеющие отношения к данной ситуации. И наконец, куски определения пинов из QSF и XDC файлов из случайных примеров в интернете, которые не имеют отношения к описанному примеру, так как в нем во-первых эти файлы не используются (другой вендор, другой способ задания пинов), а во-вторых, в нем эта часть проекта абстрагирована (пользователю вообше это не нужно это делать).</p><p>То есть текст просто водит читателя за нос, не давая ему никакой полезной информации для решения проблемы. Но даже это не важно, потому что читатель этот текст читать не будет, так как учует LLM в заголовке и убедится в третьем предложении, после чего перестанет читать. Текст является иллюстрацией терминов "сделать на отцепись" и "из дерьма и палок".</p><p>UPD: И самое страшное: это 27 страниц вместо 1 страницы полезной инструкции, которую я ожидал. ДВАДЦАТЬ СЕМЬ СТРАНИЦ ЛАБУДЫ !!!</p><p>Я хочу обратно в годы, когда этого ужаса не было. Нашу цивилизацию ждут тяжелые времена. Я уже видел в ЖЖ посты агитирующие на перевод всей порноиндустрии на generative AI.</p></div></div><!----><!----></div><div></div></div></div><div class="tm-separated-list tm-separated-list_clipped

today we encounter yet another “tough nut” in the CAPTCHA universe – FunCaptcha (Arkose Labs).</p><p><strong>FunCaptcha</strong> is a type of CAPTCHA developed by Arkose Labs that offers users small puzzles instead of the usual tasks like recognizing distorted text or selecting images containing buses. In traditional CAPTCHAs (e.g., reCAPTCHA), verification often relies on recognizing distorted characters or simple images. Arkose Labs took a different route: their “entertaining” CAPTCHAs feature interactive challenges with 3D objects, logic puzzles, and audio questions. This approach is intended to be user-friendly for humans while complicating life for bots.</p><p>Typical FunCaptcha challenges include:</p></div></div><!----><!----></div><a

correctly. Although working with kids might seem fun and entertaining, it takes certain skills to get them engaged in testing your product and voicing their opinion so you could gather all the necessary information. It’s important to understand that mentally kids function differently than adults, so working with a young target audience requires a different approach. Treating children like adults in the UX research process can lead to serious mistakes: they might not get a proper understanding of your product and you might end up getting wrong results, only wasting your time and budget. In order to avoid that, we’ve collected a few tips below that might help you communicate with kids more effectively for a productive and fruitful research session.</p></div></div><!----><!----></div><a href="/en/articles/907210/" class="tm-article-snippet__readmore"><!--[--><span>Read more</span><!--]--></a></div></div><div

<u>CAFFEINE</u> </strong>SUBSTITUTE</p><p>Although <strong><u>caffeine</u></strong> stimulates mental activity and aids in <strong>e</strong>Sports/games and late-night programming, it has many <strong>side effects</strong>, such as <u>increased blood pressure</u> and <u>crazy heart rate</u>, a sharp rise and quick drop in stimulation. Therefore, we need a high-quality alternative to caffeine, and we will search for it using AI. Potential candidates to replace caffeine are Theacrine (or TeaCrine) and N-Phenethyldimethylamine Citrate (USA FDA said Ok).  </p><p>ChatGPT successfully created a very complex table, even with a calculated column based on FUZZY criteria (if you can do this in SQL — you're a genius!), but it struggled with sorting the table. Attention: there is an image below, links are not clickable.</p><figure class="full-width "><img src="https://habrastorage.org/getpro/habr/upload_files/6b1/bb7/423/6b1bb74234ca5fee1cbbe9b90c08a901.png" alt="this is an image, links are not clickable" title="this is an image, links are not clickable" width="1200" height="366"><div><figcaption>this is an image, links are not clickable</figcaption></div></figure><p>In the first numeric column, it failed to sort the numbers in descending order. I spent about 15-20 minutes trying. I experimented with various prompts and explanations. This is strange.</p><p>This tool (<strong>ChatGPT</strong>) <u>understands table manipulation commands very well</u>. In this example, I asked it to create a table based on data from large stores, specified which columns were needed and what information they should contain, indicated the order of the columns, including relative positioning — for instance, "insert a column with such-and-such data before this column" — and even more. </p><p>IT was able to create a <strong>SUMMARY</strong> column based on previously generated columns — this is the column with weighted sums of substance weights from other columns, and IT independently found the weighting coefficients quite accurately. </p><p>Moreover, for each product, IT managed to identify the substance composition based on specific criteria and listed them, creating a separate column. Not all substances, but only those filtered by certain criteria (only those that are not caffeine but have an effect similar to caffeine — try programming such a query in SQL manually without AI, taking into account the <strong>fuzzy criterion</strong> of similarity of effects, and also determine the similarity coefficient for creating the weighted sum of substance masses per serving of the dietary supplement). And it even partially managed to sort by the <u>weighted sum</u>. </p><p><strong>But despite completing so much complex work, it still made a small mistake with sorting</strong>.</p></div></div><!----><!----></div><div></div></div></div><div class="tm-separated-list tm-separated-list_clipped tm-post-snippet__meta-list"><span

boring… I’d rather start like this—continuing to explore the amusing world of CAPTCHAs, I finally stumbled upon the Chinese variant of protection: the GeeTest CAPTCHA. Let’s break down what this beast is, where it dwells, and why you should (or shouldn’t) fear it… You’ll understand as we go!</p><p>GeeTest is one of the advanced anti-bot systems combining user puzzles with behavioral analysis. I decided to take a close look at recognizing the GeeTest CAPTCHA under real-world conditions and figure out how to bypass GeeTest with various methods. But first—a classic introduction (which, by the way, may be more interesting than the practical part of the article, since bypassing the GeeTest CAPTCHA is already a non-trivial task for many readers).</p></div></div><!----><!----></div><a href="/en/articles/903870/" class="tm-article-snippet__readmore"><!--[--><span>Read more</span><!--]--></a></div></div><div

article-formatted-body article-formatted-body_version-2"><p>The whimsical image of a chess knight in profile among the stars is perhaps the most recognizable among deep space objects. It can be said that the Horsehead Nebula tops the recognition rankings among nebulae and galaxies. Perhaps the Andromeda and Orion Nebulae resonate more with the general public, but only specialists and advanced amateurs know what they look like. Even among them, there are often cases when the famous Andromeda Galaxy is confused with another galaxy, even by experienced popularizers of astronomy. The Orion Nebula, too, can look different in pictures taken with various filters. Yet, the profile of the chess knight allows every inhabitant of Earth to recognize that in front of them is the one-of-a-kind and completely unique Horsehead Nebula.</p><p>Let's begin by noting that when we talk about the Horsehead Nebula, we refer to two fundamentally different formations in this region of our Galaxy. Only together do they create this memorable visual image. Moreover, what we see—the glowing diffuse background—is not the Horsehead Nebula. It is a dark silhouette against a light background—a bizarrely shaped dust cloud opaque to the visible radiation of stars and nebulae. If there were no relatively bright emission nebula behind it, we might not even know about any dark gas-dust cosmic horse.</p><p>The background for the recognizable horse profile is created by the hydrogen nebula IC 434, discovered by William Herschel in the late 18th century. However, Herschel did not notice any amusing details in the outline of this nebula, although he was an excellent observer—much more keen-sighted and attentive than most of his followers. There are also objective reasons for this—telescopes in Herschel's era were imperfect, and their dark metal mirrors lost from 50% to 80% of the light that entered them.</p></div></div><!----><!----></div><a href="/en/articles/903436/" class="tm-article-snippet__readmore"><!--[--><span>Read more</span><!--]--></a></div></div><div

It can be said that the Horsehead Nebula tops the recognition rankings among nebulae and galaxies. Perhaps the Andromeda and Orion Nebulae resonate more with the general public, but only specialists and advanced amateurs know what they look like. Even among them, there are often cases when the famous Andromeda Galaxy is confused with another galaxy, even by experienced popularizers of astronomy. The Orion Nebula, too, can look different in pictures taken with various filters. Yet, the profile of the chess knight allows every inhabitant of Earth to recognize that in front of them is the one-of-a-kind and completely unique Horsehead Nebula.\u003C\u002Fp\u003E\u003Cp\u003ELet's begin by noting that when we talk about the Horsehead Nebula, we refer to two fundamentally different formations in this region of our Galaxy. Only together do they create this memorable visual image. Moreover, what we see—the glowing diffuse background—is not the Horsehead Nebula. It is a dark silhouette against a light background—a bizarrely shaped dust cloud opaque to the visible radiation of stars and nebulae. If there were no relatively bright emission nebula behind it, we might not even know about any dark gas-dust cosmic horse.\u003C\u002Fp\u003E\u003Cp\u003EThe background for the recognizable horse profile is created by the hydrogen nebula IC 434, discovered by William Herschel in the late 18th century. However, Herschel did not notice any amusing details in the outline of this nebula, although he was an excellent observer—much more keen-sighted and attentive than most of his followers. There are also objective reasons for this—telescopes in Herschel's era were imperfect, and their dark metal mirrors lost from 50% to 80% of the light that entered them.\u003C\u002Fp\u003E","imageUrl":"https:\u002F\u002Fhabrastorage.org\u002Fr\u002Fw780\u002Fgetpro\u002Fhabr\u002Fupload_files\u002Fffa\u002F299\u002F09b\u002Fffa29909b927a73d88b22889301f3f3d.jpg","buttonTextHtml":"Read more","image":{"url":"https:\u002F\u002Fhabrastorage.org\u002Fr\u002Fw780\u002Fgetpro\u002Fhabr\u002Fupload_files\u002Fffa\u002F299\u002F09b\u002Fffa29909b927a73d88b22889301f3f3d.jpg","fit":"cover","positionY":0,"positionX":0}},"status":"published","plannedPublishTime":null,"checked":null,"format":"review","readingTime":6,"complexity":"low","isInBlacklist":null,"flowNew":null,"tags":[{"titleHtml":"space"},{"titleHtml":"science"},{"titleHtml":"orion"},{"titleHtml":"universe"},{"titleHtml":"astronomy"},{"titleHtml":"nebulae"},{"titleHtml":"horsehead nebula"}]},"903490":{"id":"903490","timePublished":"2025-04-23T07:16:18+00:00","isCorporative":false,"lang":"en","titleHtml":"Yandex huge privacy issue or not?","editorVersion":"2.0","postType":"article","publicationType":"article","postLabels":[{"type":"sandbox","typeOf":"system","title":"From sandbox","data":{"url":null}}],"author":{"id":"4982895","alias":"zangico","fullname":"Nico","avatarUrl":"\u002F\u002Fhabrastorage.org\u002Fgetpro\u002Fhabr\u002Favatars\u002F756\u002Fb19\u002Fec1\u002F756b19ec1a28939c5ff3bbb5a1f66630.png","speciality":null},"statistics":{"commentsCount":1,"favoritesCount":1,"readingCount":1710,"score":5,"votesCount":4,"votesCountPlus":4,"votesCountMinus":0},"hubs":[{"id":"50","alias":"infosecurity","type":"collective","title":"Information Security","titleHtml":"Information Security","isProfiled":true,"relatedData":null},{"id":"22026","alias":"itcompanies","type":"collective","title":"IT-companies","titleHtml":"IT-companies","isProfiled":false,"relatedData":null}],"flows":null,"relatedData":{"vote":null,"unreadCommentsCount":0,"bookmarked":false,"canComment":false,"canEdit":false,"canViewVotes":false,"votePlus":{"canVote":false,"isChargeEnough":false,"isKarmaEnough":false,"isVotingOver":false,"isPublicationLimitEnough":false},"voteMinus":{"canVote":false,"isChargeEnough":false,"isKarmaEnough":false,"isVotingOver":false,"isPublicationLimitEnough":false}},"leadData":{"textHtml":"\u003Cp\u003EHi to everyone!\u003C\u002Fp\u003E\u003Cp\u003EI'm new here.

This approach is intended to be user-friendly for humans while complicating life for bots.\u003C\u002Fp\u003E\u003Cp\u003ETypical FunCaptcha challenges include:\u003C\u002Fp\u003E","imageUrl":"https:\u002F\u002Fhabrastorage.org\u002Fr\u002Fw780\u002Fgetpro\u002Fhabr\u002Fupload_files\u002F932\u002Faa0\u002F6cf\u002F932aa06cf8b307028833012319c5cd4d.jpg","buttonTextHtml":"Read more","image":{"url":"https:\u002F\u002Fhabrastorage.org\u002Fr\u002Fw780\u002Fgetpro\u002Fhabr\u002Fupload_files\u002F932\u002Faa0\u002F6cf\u002F932aa06cf8b307028833012319c5cd4d.jpg","fit":"cover","positionY":0,"positionX":0}},"status":"published","plannedPublishTime":null,"checked":null,"format":"review","readingTime":12,"complexity":"low","isInBlacklist":null,"flowNew":null,"tags":[{"titleHtml":"funcaptcha"},{"titleHtml":"arcose lab"}]},"908756":{"id":"908756","publicationType":"post","timePublished":"2025-05-12T16:24:43+00:00","lang":"en","editorVersion":2,"textHtml":"\u003Cp\u003EУ меня есть знакомый энтузиаст LLM, который также изучает верилог. Я попросил его написать инструкцию к упражнению с неким сенсором, который он интегрировал. Он разумеется сбросил это на LLM, я почитал и понял, что LLM нужно запретить как распостранение Экстази и \"солей\" среди молодежи. Точно так же как \"дизайнерские наркотики\" дают ощущение счастья и достижения без труда, сгенеренная LLM документация выглядит как реальная, вот только читателю она не поможет.\u003C\u002Fp\u003E\u003Cp\u003EЧто нужно читателю? Картинку как подцепить сенсор к плате, временную диаграмму сигналов которые от него выходят и пару слов про проблемы, которые у него возникнут (дребезг) и как их стоит решать. Так чтобы было достаточно информации, чтобы сесть и написать код на верилоге.\u003C\u002Fp\u003E\u003Cp\u003EЧто выдал LLM? Сначала пять абзацев мутного словестного описания что \"изменения переключателей проходят некоторую последовательность, позволяющую определить направление\", с галлюцинациями что движется и что неподвижно. Потом не имеющую отношения к задаче информацию, из каких материалов делаются эти сенсоры в разных странах мира, чтобы быть дешевыми для хоббистов и образовательных учреждений. Далее про разные способы решения проблемы дребезга, в том числе способы, не имеющие отношения к данной ситуации. И наконец, куски определения пинов из QSF и XDC файлов из случайных примеров в интернете, которые не имеют отношения к описанному примеру, так как в нем во-первых эти файлы не используются (другой вендор, другой способ задания пинов), а во-вторых, в нем эта часть проекта абстрагирована (пользователю вообше это не нужно это делать).\u003C\u002Fp\u003E\u003Cp\u003EТо есть текст просто водит читателя за нос, не давая ему никакой полезной информации для решения проблемы. Но даже это не важно, потому что читатель этот текст читать не будет, так как учует LLM в заголовке и убедится в третьем предложении, после чего перестанет читать.
