Two years ago, when a close friend of the family (let's call him D) was sick, I took him to tour the hospitals in Saigon. The whole experience was Kafkaesque. D needed major surgery. A doctor at a large public hospital said that D's surgery must be the first operation on a Monday. If we missed that slot, we'd have to wait another week. When I asked why it must be the first slot on a Monday, the doctor asked if I ever went swimming, and without waiting for me to answer, he revealed with a smirk that their only operation room is like a public swimming pool, it's only clean on Monday. Although D could take the surgery as an outpatient, the doctor recommended that D should be admitted as an inpatient to increase his chance to win the first slot of the week's lottery. However, when I tried to enroll D, the hospital couldn't find any bed for him. The nurse recommended placing D on a gurney for a few days while waiting for the next available bed. "It's outside in the hallway, so at least you don't have to share a room with other people," I wasn't sure if the nurse was joking and at that point I was afraid to ask. We said thank you and went home. I couldn't fathom leaving D in his most vulnerable moments out in a hallway. Luckily, a short while later, we found a solution, which I’ll save the story for another day. D is okay now. However, what happened during those dark days still bothers me to no end. Whenever I go swimming, I’d remember the doctor’s remark, and start to wonder about death by contamination. It’s obvious to me that Vietnam can use many more hospitals, but I had no idea how to help. The most ambitious structure I ever built was a Lego house ??. Near the end of 2022, through a series of faithful coincidences, I found myself having lunch with an ambitious couple who have founded multiple successful healthcare businesses. Guess what they wanted to build next? Hospitals! Fast forward to today, I'm so proud to share that Calif Engineering Team has helped build the technical infrastructure for two brand new private hospitals in Saigon. It wasn't an easy job. We faced countless issues, technical and non-technical. The stakes sometimes couldn't be higher: If the computers go down, people might die. Luckily, the talented engineers that we sent to this project are excellent at dealing with setbacks. I wish I could stay calm and cool like them during times of distress. We've gone so far, learned so much, yet are nowhere near done. Vietnam still needs many more hospitals, with more reliable and secure technical infrastructure. Judging from the international healthcare software that we've audited, Vietnam is not alone in this need. Come join us to help build more hospitals: https://jobs.calif.io.

I grew up reading Joel Spolsky. You might not recognize his name, but you might have heard of Stack Overflow, of which Joel is a co-founder. He also created the project management software Trello. He sold the two companies for more than $2B. But what's made me a fanboy is his blog on software business Joel On Software. Joel has strong opinions about how to run a company, but there is one sentence of his stuck forever in my mind: Programmers are [...] stars. Stars go first class. Get used to it. His team had private offices, flew first class, worked 40 hour weeks, and bought people lunch, Aeron chairs, and top of the line computers. And it works wonders. So when we started Calif, we copied his formula. Since the earliest day when we didn’t have much revenue, everybody here always travels business class and stays at five star hotels when on business. A team member once asked why I wasted so much money. I said well we are stars, and I read on the Internet that stars don’t wait in line. I believe business must pay. If we can’t generate enough revenue, either our work is worthless or I’m doing a bad job selling it. Either way we should close shop and go home. Of course as a self-bootstrapping company we have to think about the runway, but the runway must take into account all the perks. I’d rather shut down the company than saving a few bucks cutting costs. If the business ain’t working, switching to economy class won’t help. Who wants a slow, painful death? Not me. There are also practical reasons. We’re helping the poor and the have-not, but our largest clientele are the elite. I believe sales can only go down, not up. If we want to sell to the elite, we must be more elite than the elite. Otherwise they won't trust us. This means we must do everything in style and with great care. I also believe we can’t serve our clients if we don’t live their lives. Money can't buy happiness, but it sure can buy time, comfort and convenience. Since we fly business, we can just go to the airport and take the nearest flight. The first time I did this I didn't believe it was possible. It has saved me countless meetings that would have been late otherwise. If I sound like bragging, it's only because your employer doesn't treat you as you deserve. This is the standard. We aren't even flying first class (we’re getting there). As a great hacker, you deserve better. Come join us and never look back!

We analyzed a variant of LockBit v3 ransomware, and rediscovered a bug that allows us to decrypt some data without paying the ransom. We also found a design flaw that may cause permanent data loss. This is a joint work with Chuong Dong. Enjoy! https://lnkd.in/gwNrGqCw
