So, when I talk about dying Boomer Machine Shops? This is them.
Pan around and not a single capital asset is under 2 decades old. Couple of manual mills, a really old Brother TC22, a Mori Dura Verical. Shop is immaculate, that part being shown off is super clean…
But it is also a part that would have been a real talent show 20 years ago- probably 2-3 days of fussy setups and dial-in. Now? Fire that off to SCS and Phil’s programmer will spend 20 minutes tweaking the templates before he sends it off to the Brother U500 fleet’s auto cue and moves on. No mess. No fuss. No heroics.
The technology moved on and this shop didn’t. Many such cases - you get that vendor contract from Raytheon or Lockheed, you struggle to figure it out at first, then you coast for the next 15 years and the process/machines/your skills stay static. When you go to retire, the shop isn’t worth bupkis - Raytheon will re-quote to a modern shop that can onboard this easily because they are all 5 axis and won’t struggle, any “buyer” of the company will get hosed when he bought $35k in auction value equipment for $600k.
And not to pile on this guy, but I’m also willing to bet $5 he couldn’t find anyone to work for him. Anyone off the street would not have found 110% of CA McDonald’s wages all that appealing. Anyone with experience and talent in this industry is not going to want to have a boss for the privilege of babysitting old ass equipment that they could go by themselves off Craigslist.

Ethical hacking tutorial 💻

In this guide, I will demonstrate how a malicious actor might execute a VNC brute force attack to gain unauthorized access and control over a targets computer.

Virtual Network Computing (VNC) is a graphical desktop-sharing system that allows one device to remotely operate another.

What Took Down A Myriad of Public & Private Sector Websites & Digital Services In Kenya Yesterday? Here's What Happened & How To Sort It Out In The Future.

Yesterday, a myriad of public and private sector websites and digital services in Kenya went offline due to a series of cyberattacks. Those affected included Safaricom's ubiquitous M-Pesa mobile money service, the Kenyan Government's eCitizen portal, Kenya Power's USSD shortcode, Standard Chartered Bank, NCBA Bank, and many others.

In a nutshell, what happened was widespread DDoS, or Distributed Denial of Service cyberattacks, which are essentially a form of digital congestion. It's as if you are trying to drive on Thika Road during rush hour but all of a sudden, thousands of additional cars, buses, and trucks flood the road. Chaos, right? That's pretty much what a DDoS attack does to a website or digital service as was the case yesterday. It sends so much traffic that a website or online service can't handle it and ends up stuck in its own digital traffic jam!

So, how did this happen? Well, hackers who launch a DDoS attack use a bunch of computers (like, thousands of them, globally) that they've infected with a virus. It's like having a digital army of computers, also called a botnet, at their disposal, ready to unleash chaos. In Kenya's case, they sent these botnets to visit the affected websites and digital services all at once, causing massive overloads that kept them offline. It's basically a form of digital sabotage!

Preventing DDoS attacks is not easy and requires a multi-layered approach. On the network level, organizations can install rate limiting, which restricts the number of requests a server will accept in a certain timeframe from a single IP address.

Advanced threat intelligence systems can also help identify botnet traffic patterns and block them. Think of it like traffic police that divert cars when there's an accident so these services direct the traffic through different servers, which act like filters to keep out the bad stuff and let through the good.

On a personal level, everyone should ensure that their digital devices are secure to prevent them from being a part of these DDoS botnets. This includes keeping software and hardware updated, using strong and unique passwords, and being cautious about clicking on suspicious links or downloading untrusted software and apps. 

Digital security isn't a one-time deal - it's an ongoing commitment, almost like a game of digital chess to stay ahead. These recent DDoS cyberattacks in Kenya are a wake-up call for organizations and individuals so we have to keep learning, stay updated on new cyber threats, and most importantly adopt best practices for cybersecurity.

I got this email from Starlink today and my heart skipped a beat! It's been quite a few months since I paid the pre-order booking fee online and it seems the Starlink terminals will start shipping in Kenya in a few week's time.

However, this is only half the story as I nearly had a heart attack once logged into the Starlink website and had a look at what it would cost to secure my order for the same.

Buying the Starlink terminal will set you back a total of Kes. 89,000 which includes a shipping fee of Kes. 3,100. At the same time, the monthly subscription would be Kes. 6,500 which doesn't seem ridiculously priced but is still more than what I currently pay for my home Internet service.

But the real killer was this notice on the Starlink website when you want to complete the sign-up process:

'Starlink is currently available in your area using inter-satellite links! You can expect Starlink’s typical high-speed internet with brief periods of intermittent service and high latency.

Users will be able to engage in common internet activities like email, online shopping, or streaming a movie, but they won’t be able to engage in activities like online gaming or video calls. Service will improve dramatically over the next year.'

I was like, hang on a second?! What's the point of getting Starlink if their Internet service is expected to be possibly slower or the same as what you have at home or on 4G or 5G in Kenya? Not to mention the high cost of acquiring the Starlink terminal? I. Have. So. Many. Questions....

That being said, this is Kenya? So, consumers and businesses are always keen to try the next big thing in technology and Starlink is no exception. There will be scenarios where it could be the only viable alternative in really remote locations, also known as the 'bundus'.

Ultimately, I can see Starlink demand outstripping supply, right out of the box. Mark. My. Words. This is Kenya and we don't come to play when it comes to our Internet! These sorts of things are taken seriously in a market where Internet access has become something of a basic human right for over 30 million Internet users :)

YOU CAN NOT BE ON SOCAIL MEDIA

You gotta get off here…. Too much comparison, too much distraction and clutter in the mind

Go outside. Go challenge the body and mind with physical fitness
Eat good food. You must cut out all the junk.

“But, but I learn on here” sure. But what has that lead to? Look at your situation.

Go heal yourself. No one* can do this for you

today I learnt that how we make ugali (starches) - big portion, served with a smaller portion of eggs/meat etc is called a Starch and Relish framework. The starch's purpose is fullness (satiety), then the relish is for just that. And yes, this has colonial-era roots

Every once in a while, you learn a bit too much to realise just how little you know. And somehow, at these very points of inadequacy, life just casually drops opportunities you've been chasing for ages right on your lap.

The universe has a very sick sense of humour.
