Happy 19th birthday to my bicycle. I take absolutely no care of you. I leave you out in the rain. I ram you through snow and mud and up and down kerbs. I make you drag stuff too heavy for you. I rarely remember to feed you with oil and air. I fling you onto trains and into hedges and into any space you fit, or don’t. And yet you always work, cost little to maintain and nothing to run. And you give me easy exercise. And I will never be too old not to think Wheeee! as I freewheel you downhill.

My trusty faithful old silver-coloured Kildemoes bike parked alongside other bikes at a bike rack, a rucksack in the big silver aluminium basket. It’s a city bike, a comfy sit-up-and-beg bike with big wide handlebars. The bikes here are all higgeldy-piggeldy, parked in different directions instead of in the actual wheel slots. Not because we’re edgy and cool, but because the racks were full earlier so some bikes had to be parked willy-nilly wherever you could find space. There are winter leaves on the ground; the edge of a nice big old tree trunk to the left; an empty side road beyond; and across from us, trees at the edge of the woods.

정신적으로 취약한 상태에 있는 사람이 듣기 좋은 말만 해주고 + 누군가를 적으로 지목해 함께 적대감을 불태우는 방식으로 건강하지 못하게 단결력을 가지는 에코체임버에 둘러싸여 정신적으로 악화되는 상황에 놓여있을 때 거기서 빼내기 위해 쓴소리를 좀 해줘야 하는데, 문제는 그런 상황에 처한 사람들은 쓴소리도 다 적으로 간주함… 얼마나 잘 돌리고 돌려서 말할수 있는지 심리 이해와 화술이 관건인데 모두가 오은영이 될 수는 없으니

3. Trusted Verifiers are in keeping with our ethos -- that Bluesky shouldn't be the sole verifier, and that there should be systems that exist outside of us as part of a robust civic infrastructure. The world shouldn't depend on massive social companies as the sole authorities 2/2

A couple of quick thoughts on this before I disappear for my morning block of meetings 1. Domains are still valuable identity signals! Multiple methods are good to have 2. Identity verification will continue to evolve from here 1/2

We’re introducing a new layer of verification on Bluesky — a user-friendly, easily recognizable blue check. In addition to account verification issued by Bluesky, we're also introducing Trusted Verifiers. Select independent organizations can verify accounts directly.

復活節第二日,睡了長長一覺,醒來依稀記得四月底哪天是教廷封聖第一位互聯網主保聖人的日子,算是千禧年誕生的第一位聖人。此前一直關注這件事,於是去查到底幾號封聖,好寫一篇相關文章致意,一查居然發現教宗方濟各今天早上突然去世了,互聯網主保封聖禮無限期延遲。
想起前一陣子突然去看的電影《教宗選戰》,開幕也是從教宗去世開始,有點感慨電影看成了預言。
而教宗去世正好落在互聯網主保的封聖周,就覺得有點奇怪,怎麼感覺像是AI幹的。
不知道天主教庭的下任教宗是甚麼樣的,教廷如何回應這個人性空前獲得挑戰的AI時代,和面對AI的偶像崇拜可能造成的空前災難。
懷念教宗方濟各,曾經有段時間,每週讀他的禱文和釋經,獲益良多,他的釋經很有個人特色,舉例詼諧,帶著他的幽默,總是充滿著對窮人和受苦人的無盡悲憫,也感慨他真的服務到了生命的最後一刻。

前幾天看到有人在討論程式一開始要教什麼。我自己蠻幸運的,高中資訊老師是用具體的樂高教程式邏輯。

老師上課教完基礎的指令後,會給大家場地迷宮,看看大家可以怎麼用創意解題。你可以看到你用迴圈、邏輯可以讓樂高機器人做出很多動作,甚至額外搭上感光元件,就可以寫更多情境判斷。

記得高中也有嘗試寫VB寫俄羅斯方塊,
練習如何把大的問題猜解成小問題解。先考慮方塊如何移動、下降、旋轉、碰撞判斷。每解一個問題就會離完成遊戲更靠近一步。

老師也不會直接跟我說答案,通常是聽我講完我的解法,再小小提示我想要的功能可以用哪些關鍵字查到,或是直接示範一次這個屬性或函數可以達到什麼樣的功能,再讓我回去試試看在俄羅斯方塊裡怎麼實現。

雖然後來沒有用VB做完,但還是頗有成就感的。

能夠學到怎麼用程式思維拆解任務、尋找答案。我覺得是程式教育最需要交給學生的東西。

안녕하세요, 플래닛입니다.

최근 사이버불링 계정의 반복적인 가입으로 인해 부득이하게 회원가입을 일시 제한하게 되었고, 이로 인해 많은 분들께 심려를 끼쳐드렸습니다.

자체적인 조사와 많은 분들의 협조로 용의자를 특정할 수 있었으며, 이에 따라 더 이상의 가입 승인 절차는 불필요하다고 판단하여 회원가입을 다시 개방하였습니다.

앞으로도 모두가 안심하고 사용할 수 있는 SNS 환경을 만들기 위해 최선을 다하겠습니다. 감사합니다.

I've been on a really long journey with my health and decided that it's time to share a bit more. I've learned so much (and have so much left to learn) and want to put this out there in case it helps anyone dealing with something similar.

When the user “goes back” in their browser, two things can happen:

1. the previous web page is loaded from the network
2. the previous web page is re-rendered from memory locally

Does the user have any control over this? Can they choose which one happens? Can they force one over the other?

가끔 올리면 좋아해주시는 레일즈 기기괴괴 시리즈


현상 : DB 쿼리하는 로직에 캐시를 달았는데도 계속 DB로 쿼리가 날아간다.

삽질 끝에 발견한 원인: 쿼리 결과가 캐싱된게 아니라, '쿼리를 날린다' 라는 행위가 캐싱돼서 캐시를 읽을 때마다 매번 쿼리를 날리고 있었다...

所以今天在开了一个视频会议过后,我大概知道怎么在不安装这个腾讯会议客户端的情况加入腾讯会议了 :blobcatgoogly:

首先打开 voovmeeting.com/r ,这个是腾讯会议的海外版,注意一定要有/r,不然还是满屏要你装软件 :blobcat_thisisfine:

然后点右上角登录,用Google登录即可,不建议注册,我注册的时候密码有要求,但是提示框只在提交的时候出现,闪一下就没了,再提交就会变成邮件验证码错误,5次后rate limit,我到最后也没看清楚它到底要求什么密码 :blobcat_thisisfine:

这个网页版当然是支持摄像头的,但是肯定不支持投屏!那么为了投屏,我们就可以请出老朋友obs-studio,下面Sources添加Screen Capture(没有的话是xdg-desktop-portal有问题),右下角打开Start Virtual Camera(没有的话是没开v4l2loopback内核模块,或者没装polkit),然后重进会议,就可以用虚拟摄像头投屏了 :blobcatthumbsup:
