#lessonlearned — Public Fediverse posts

I've been 3D-printing for around five and a half years. So I'm not a rookie, but I just made a #rookie #mistake.

I've spent the last couple of weeks making compartments and dividers and such for the toolboxes I take to the Repair Cafe. Lots of test #prints to check fits and footprints, full prints, changes to design based on lessons learned during use at the last cafe, etc. I've put around three kilograms of #filament through my printer in that time.

Then, in the last couple days, I started having various problems. At first they only showed up on big prints - #adhesion and #curling, which I've had before when pushing the limits of my bed size. But prints seemed to be getting #sloppier, and I had a couple of spaghetti explosions.

Tonight, I finally took the #hotend apart and looked at it closely - it's very difficult to do when the printer is fully assembled, because it's a #delta printer.

Lo and behold, the nozzle appeared worn. And that can account for all the problems.

I should have checked this sooner - but I've only been printing plain #PLA, nothing abrasive, so I didn't think of it. Lesson learned.

Pardon the shitty photo from a cheap digital magnifier. The old #nozzle #orifice is about 1.5x the diameter of the new one - so 2.25x the area. No wonder plastic was going everywhere but where it should go!

Seems to be printing *much* better with a new nozzle.

If I can offer a little piece of advice: if someone gives you a freshly baked blondie at a party, don’t tell them it tastes just like Debbie Harry.

Did something that was overdue a long time ago…
Hardened my Arch Client.
Firewall was already set up and i installed Fail2Ban.
Configured that and also changed the SSH Port plus I set the verification to key only.
But I just wasn’t able to access the machine, even within itself via SSH.
After maybe an hour or two of troubleshooting I found out what was the cause.
Since all my Repos are in one folder (with sub folders for the the repos of course) and my ssh config file was in one of those (private Repo), SSH didn’t accept the authorized_keys file as it was just a symlink in the correct .ssh folder.
Took me way too long to realize that while keys and my config file worked fine that way, the authorized_keys file didn’t.
So I deleted the symlink and moved everything except the config file to the original folder.
Symlinked the config file and voila, it worked!

Phát triển ứng dụng fitness MoveDose, cung cấp bài tập 60 giây mỗi ngày, ban đầu thu phí nhưng gặp khó do thị trường bão hòa và chi phí cao.

Tác giả đầu tư tháng cho SaaS đầu tay nhưng bỏ qua tín hiệu ngầm: tiến độ không nằm ở tính năng hay code, mà ở hành động của người dùng như quay lại tự nguyện, lặp lại nhu cầu. Câu hỏi đúng không phải "Làm sao build tốt hơn?" mà là "Liệu mình có bằng chứng đủ để xây dựng điều này?". #SaaS #KhởiNghiệp #LessonLearned #ProductDevelopment #StartupVietNam #ThànhLậpDoanhNghiệp

Mất một dự án vì đề xuất "chưa chỉn chu" dù dịch vụ tốt hơn. Khách hàng đánh giá cao hình thức trình bày hơn nội dung. Từ đó, tôi vẫn viết trong Google Doc nhưng dùng Gamma để chuyển thành slide chuyên nghiệp. Tỷ lệ chốt đơn tăng từ 20% lên 40%. Bài học: bao bì quan trọng không kém chất lượng. #PresentationMatters #LessonLearned #KinhDoanh #Marketing #Freelance #SaaS

Mình từng dành hàng tuần để xây dựng một MVP – giao diện đẹp, backend ổn, nhưng KHÔNG AI cần dùng. Không ai sẵn sàng trả tiền, vì nó không giải quyết vấn đề thực tế. Bài học đau đớn: MVP không phải là sản phẩm tối giản, mà là cách giảm rủi ro. Nói chuyện với 10 người dùng sớm quan trọng hơn coding 100 giờ. Bây giờ, mình bắt đầu bằng hội thoại, không phải code. #MVP #Startup #LessonLearned #SaaS #KhởiNghiệp #ThấtBạiĐểThànhCông

Khi xây dựng SaaS, tác giả từng bỏ qua tín hiệu quan trọng: "sự thiếu khẩn cấp". Lời khen "ý tưởng hay" không bằng việc người dùng thực sự khao khát sản phẩm. Hãy chú ý hành vi, giải pháp tạm thời của người dùng và sự theo dõi thay vì chỉ lắng nghe những lời khen ban đầu. Bài học là cắt bỏ sớm thay vì xây dựng quá lâu.

Khi khách hàng phàn nàn công khai, thay vì phòng thủ, tôi đã công nhận lỗi và hứa khắc phục. Cách xử lý minh bạch này đã biến khủng hoảng thành cơ hội, thu hút 14 khách hàng mới. Bài học: Sự có trách nhiệm được đánh giá cao hơn sự hoàn hảo.

Một nhà phát triển đã từ bỏ dự án chỉnh sửa ảnh sau hơn 4 tháng vì người dùng không sẵn lòng trả tiền. Anh ấy cảm thấy tiếc nuối và đang nghĩ đến việc tạo một "bãi phế liệu" để mọi người chia sẻ các dự án bỏ dở và bài học kinh nghiệm. Bạn có từng cảm thấy thế không?

Dành 6 tháng tối ưu server cho 0 user, một dự án SaaS thấy mình bị AI miễn phí như Gemini vượt mặt. Giờ họ buộc phải mã nguồn mở tất cả. Bài học đắt giá: đừng chờ sản phẩm hoàn hảo, hãy ra mắt ngay.

Một câu chuyện đáng suy ngẫm: Dành 6 tháng build feature, khách dùng một lần rồi yêu cầu gỡ bỏ. Bài học: Đừng chỉ xây dựng theo yêu cầu của khách hàng. Hãy đào sâu vào vấn đề cốt lõi của họ để tìm ra giải pháp thực sự. Yêu cầu là manh mối, vấn đề mới là mục tiêu.

Doanh nghiệp đã điều chỉnh chiến lược marketing sau khi phỏng vấn khách hàng, nhận ra 80% ngân sách đầu tư sai chỗ. Chỉ 10% khách hàng sẵn sàng mua hàng ngay khi thấy quảng cáo, còn lại cần thời gian qua Reddit, video, và khảo sát nhiều lần. Bây giờ họ ưu tiên xây dựng thương hiệu, cộng đồng trước, sau mới chạy quảng cáo. Giải pháp: Tài liệu đơn giản "Mục tiêu, Thấu hiểu, Hành động, Đo lường". #MarketingChuyểnĐổi #ChiếnLượcThươngHiệu #DigitalMarketing #LessonLearned #KinhDoanhIQ #MarketingVietNa

Làm quản lý vận hành tại startup 28 người, tôi chọn dịch vụ payroll phổ biến với giá $6,600/tháng (11 hợp đồng quốc tế). Khi đổi kế toán, anh ấy cười to khi thấy hóa đơn: "Bạn trả gấp 3 giá thị trường!" So sánh với 2 startup khác, chỉ mất $3,800-$4,100/tháng. Trong 14 tháng, công ty mất $30k chỉ vì không so sánh giá. Bài học đắt giá: Đừng chọn tên "lớn" mà không so giá!

Aujourd'hui j'ai fait de la conduite et du freinage d'urgence sur plateau, ça montre bien le pouvoir extrêmement théorique des freins sur route humide et revêtement glissant.

Debout sur les freins, l'utilitaire lancé à 30 km/h dans une descente ne s'arrête même pas.

Je suis maintenant complètement convaincu que les freins sont un scam pour nous faire acheter des plaquettes et autres trucs inutiles. Je ne freinerai plus jamais.
