BackgroundI’ve been working with HydraDX recently and attempting to run it in Docker. Unfortunately, the last runnable version of HydraDX is significantly outdated, and it no longer connects to active peers. Furthermore, when attempting to use a more recent HydraDX Docker image, an error arises indicating “version `GLIBC_2.34′ not found.” As of the most recent version available on September 4th, 2023, identified as pr-664, this issue still persists without resolution. Following a period of challenges and without delving into the underlying causes of the issue, I decided ...继续阅读 (31)

By visualising team cooperation through these 3 concentric circles (owned, learnt, known), team members can develop a strong sense of personal responsibility, foster collaboration and learning within the team, and gain a broader understanding of the larger context in which they operate. This approach promotes a holistic and effective teamwork dynamic.Owned Circle: Take full responsibility for individual work.Learnt Circle: Understand and learn about others’ work that may impact own tasks.Known Circle: Ensure the team’s goals and the work of all team members are known to everybody.And there are ...继续阅读 (31)

最近 ChatGPT 着实火了一把，据说 GTP4 也即将发布。现在Large Language Model（LLM ）也受到了类似图像生成的 Stable Diffusion 那种高光时刻。在之前我一直有一个错误的观念，认为谁掌握着计算能力，谁才能得到最好的AI模型。直到 Facebook 2023 年二月 24 号发布了论文“LLaMA: Open and Efficient Foundation Language Models”。粗略阅读之后，我才知道原来在一个限定的预算下，大参数模型并不如小参数模型用更多的数据进行训练。当前，许多 AI 模型都依赖 CUDA，比如nanoGPT，这也就意味着必须有 NVIDIA 的 GPU来训练和运行。有这样的硬件限制，对于我这种只是想初步了解一下 LLMs 的一些基本概念的业余爱好者变成了一个比较高的门槛。所幸的是Georgi Gerganov用 C/C++ 基于 LLaMA 实现了一个跑在 CPU 上的移植版本llama.cpp。llama.cpp 甚至将 Apple silicon 作为一等公民对待，这也意味着苹果 silicon 可以顺利运行这个语言模型。环境准备我用来测试的笔记本是非常普通的 AMD Ryzen 7 4700，内存也只有 16G。不过结果看起来还是非常流畅的。由于需要从源代码编译 llama.cpp，所以 buil ...继续阅读 (28)

本文是由发布在推特上的片段思路整理，并在 ChatGPT 的帮助下完成的。感谢 ChatGPT 的支持，同时，作为人类-AI共赢计划。请大家都来当电池吧。没有人是 Neo （没有人：我不是）引子周一，晴。阳光从东方那棉絮一样的云层里漏出丝丝火焰，仔细观察，原来那棉絮其实是棉花糖。周末我剪了草、当了电工又当水工，这繁重的体力劳动后，我的大脑反而得到了良好休息，脑洞大开0.1mm。因此，我想写一篇关于生命、AI和末世幻想的序列推文。近期，ChatGPT已经火得上了天。各路神仙都已经对其进行了拆解，7×24的、圆环直径向旋转一周的角度。乐观者认为，短期内人类开始了与AI共生的新纪元；长期来看，AI将在各种领域进一步解放生产力，推进再一次的工业革命。而悲观者则反复强调，AI将替代大部分人的基础工作，短期内就会看到大量基础从业人员失业。而长期来看，这一情况会进一步加速，不论是社会财富还是人类权力，都会重新分配并更加集中。这两种观点都有自己的论据，所以都有一定的可信度。然而，考虑论据才能说话的就不能算是脑洞了，不是吗？ChatGPT 给出的可观内容：然而，我们不能仅仅局限于这两种观点的范畴之内。我们还需要更大胆、更开放、更具探索精神的思考。如果我们对AI充满信心，认为AI能够帮助我们更好地理解世界并更好地改善人类的生活，那么我们需要探索如何使AI与人类的生命更加紧密地联系在一起。这可 ...继续阅读 (21)

Recently, I set up a new developing environment in a VirtualBox VM. The source code shares between the host and VM by shared folder. It causes a problem that the config file can not be found when Nginx is starting up.Nginx can not find the specific config file which is in the mounted folder from the hostI searched on Google and found some related posts.“If Nginx does not start after rebooting the server” points out the correct direction of the solution, however, the changes of method 1 mentioned in the article is not working for VirtualBox, and personally, I don’t like the me ...继续阅读 (24)

Most of the times, I want my ESP8266 board to communicate with the server through a securer channel such as MQTT over TLS or HTTPS. However, to verify the certification, system’s date/time has to be in a proper configuration.Since ESP8266 is designed to have the network, I believeNTPis definitely the first choice and is the easiest one to use. In this post, I will show you how to get date/time and set it by using NTP.Dummy projectA dummy project is set up for this post. And of course, it can be a part of a real project since the WWW is very important to my most of side projects. The boar ...继续阅读 (34)

Recently, I found some funny “news” on Facebook.For example, a surprising mom with a new house.Or, surprised father and the dreamed motorhome.I won’t notice if they are fake or not, before the two stories displayed in my timeline at the same time only 2 or 3 contents away.If you look them closer. You will find the story actually stupid enough. Or, the school is the best, richest, top one in New Zealand, is that possible?Both of them starts the same way “Have you heard about …”. And ending with the same words “Show me your money”.(Click the images ...继续阅读 (25)

My wife sent me an EleksMill as my birthday gift (Thank you! my love). It’s simple but proper designed desktop CNC. However, the document of the CNC machine is as simple as the design. It cost me around 4 hours to assemble the machine from a piece by piece.After completed the assembling, I found the board was not initialised. So, I downloaded the firmware fromEleksMill website. Unfortunately, the official package only supplied the windows application to upload the firmware. For Linux, such as my OS Ubuntu, I have to find out another way to upload the program.Since EleksMill is based on G ...继续阅读 (28)

Since November last year, after 2degrees upgraded their network and was starting to abandon 2G cross the region, the 3G connection disconnected every 15 minutes.

IntroductiongoRBACprovides a lightweight role-based access control (RBAC) implementation in Golang. Normally, the privilege information (roles, parents, and permissions) are saved in the persistent storage, e.g. Database, Files, or Cloud Storage. This post will briefly discuss the technical details of how to load the goRBAC instance from persistent storage and how to save the instance back. In order to make things simple, I will use the JSON file as the persistent storage.Preparation / DefinitionSuppose we have 3 roles: Editor, Photographer and Chief Editor.

日日浸淫在英语环境里，突然发现好久都没有正经用中文写点东西了。所以，就还是写点什么吧。前段日子，在朋友圈和一些其他渠道看到 F 君被下课的消息。倒是不意外这个结果，只是他离职的方式，与我想象确有不同。F 君的故事，知道的人都知道了，不知道的也不必过于纠缠细节。我与 F 君从未深交，只是萍水相逢。他入职那家医疗互联网公司的时候，我也正好刚刚入职一个资本背景不错的初创健康软件公司。自然而然，细分领域的同行，我便对他的公司，和他本人有多了一些关注。当然，后来也有一些照面的交流，不过也许泛泛都算不上吧。对于他所在的公司、他本人的评论，在那时我上心关注一方面是因为在当时正好属于交集行业，另一方面他在刚刚入职那个“小论坛”的时候对我所在的公司给出过一些中肯的评价。虽然当时有些观点，我是并不认可……然并卵……Duang~结果就在那里。当然，那个“小论坛”变成大公司的时候，也进入类似的怪圈不能自拔倒也是意料之外，情理之中了。今天写这个杂文，并不是想讲 F 君的故事，也不想评论 F 君的是是非非。我只是想借 F 君事件，说说跳出一个圈子回头看的时候的过往云烟。当然更多的是说说我自己的体会吧。我与他的经历多少有点类似，用一个很阴暗，但是我觉得很贴切的比喻，如果把一个人的离职当作是岗位上人的死亡的话，F 君是被谋杀的，而我是自杀的。然而，一个岗位上的人的终结，只是人生诸多事实里很小的很小的一个环节。举个 ...继续阅读 (31)
