If you’ve ever wondered “Where did all my disk space go?”, a visual disk usage tool can answer that question in minutes.
On macOS, GrandPerspective has been a go-to for years. It scans your drive and displays a colorful treemap—each rectangle represents a file, sized by how much space it takes. Big blocks reveal large files instantly, whether it’s a forgotten video export or a massive cache folder.
On Windows, the closest match is WinDirStat. It works the same way: scan a drive, see a treemap, and drill down into directories. It also adds a handy file-type legend and a directory tree so you can clean up directly from the interface.
Both tools are free, open source, and lightweight. For moderately technical users, they’re faster and more insightful than manually poking through folders—and they make the “what’s eating my disk?” problem almost fun to solve.
There’s a saying that the best time to buy a computer is when you need one. WIth new technology always arriving, most jumps in technology are incremental. So just buy whenever. Today, in August 2020, I suggest waiting a bit longer if you can.
Apple is leading the way to end of Intel-based computers with their announcement that they will start using “Apple Silicon” in their computers. This will be a huge jump for Apple’s computers and it portends similar changes that are surely coming to the PC.
Apple CEO Tim Cook Announcing Apple Silicon (aka ARM) for Macs
42 years ago in 1978, Intel came out with the 8086 chip and the x86 architecture. Intel, along with Advanced Micro Devices (AMD) later, made practically every computer’s central processing unit (CPU). (There were many exceptions such as Motorola 68000 chips and PowerPC CPUs, but these never achieved the scale or had the long run of Intel’s CPUs.)
ARM CPUs use a different RISC-based architecture than Intel’s CPUs, and became most ubiquitous in Apple’s iPhones and iPads, as well as most Android phones. Apple will start selling Macs this year with ARM CPUs, which Apple refers to as “Apple Silicon,” justifiably since Apple puts a great deal of effort into designing and optimizing the CPUs for their devices.
ARM is already becoming popular in servers. Therefore, we only await Microsoft Windows’ move to ARM for a full transition away from the Intel era. (Microsoft Windows does have an ARM version, but it is not 64-bit and was never made to be able to run the x86 applications.)
What does an ARM CPU mean for consumers? Due to efficiencies of the ARM CPU, we will see computers that are faster, smaller, and cheaper, while also having better battery life. This is partially because Intel has hit technical snags which have kept their CPUs stagnant the last few years. While AMD has made great improvements with their Zen chips on the same x86 architecture, ARM chips are clearly the power per watt leaders of the future.
So certainly buy a new computer if you need one now. But a big jump in computing is on the way.
Windows often fills with malware and junk when kids are trying to install games. These are often “browser helpers,” alternative browsers, or other search tools. To fix these junked up computers, many users install more malware that is pretending to be helpful software.
Much of the software can not be removed using the standard “Add or remove programs” tool built into Windows. That’s when I turn to Geek Uninstaller, a lightweight tool that can force the removal of pernicious software and related traces left in the operating system registry.
Clients regularly ask me when they should upgrade their computers. Most businesses upgrade desktop computers every 4-6 years and laptops every 2-4 years. But how often should you upgrade? Here are some factors to consider:
Computer Release Cycles. It is typically best to buy a new computer model early after it is released. This can give you the latest technology and a longer product life. If a new model is just around the corner and you aren’t in dire need, consider waiting.
CPUs. The Central Processing Unit is a key component and is usually made by Intel. A new model will often be released to coincide with the latest intel CPUs (and associated motherboard, RAM, etc). Buying the latest CPUs can mean that the computer will typically allow operating system updates for a longer period.
Hard Drive (HD) versus Solid State Drive (SSD). I strongly recommend SSDs over traditional hard drives. SSDs do not have a spinning platter. They’re more energy efficient and super fast. Many people will find this gives the greatest perceptible difference in speed. Most new computers and all new Macs have an option for an SSD or a hybrid option that uses both an SSD and HD for improved performance (Apple refers to this hybrid option as a Fusion drive).
Usage. Heavy computer users such as graphics designers and developers will find it more useful to upgrade quickly than people who mainly edit documents and use a web browser. Consider if the efficiency of your work would improve enough to warrant an upgrade.
Hassle. Upgrading, especially on PCs can be annoying and take a great deal of time to configure the computer as you like. Macs are easier to upgrade, especially if you have an Apple store nearby. They will upgrade you for free and move over all your files.
PC or Mac. A sad situation that I regularly see is a PC user upgrading after their computer has been infected by a virus. This makes some sense. If the computer has been compromised and is already a few years old, it could be considered “totaled” if the money and time spent on wiping the computer and reinstalling the operating system would be better spent on a new machine. Because of this, I often recommend that people consider Apple computers (Macs) if their needs don’t include Windows specific software. Macs in my experience don’t get viruses, don’t need additional antivirus software, and tend to have higher quality parts that last longer than the typical PC. Because of these factors, Macs have a lower total cost of ownership in my experience, despite having a higher initial cost.
Security. If you have a Windows 95/98/XP PC or a Mac that is around 8 years old, you should consider an upgrade for security reasons. If your computer can’t upgrade to the latest operating system or latest web browser, then it won’t have the latest security patches and could be vulnerable to attacks.
Deals. PC deals come and go all the time from Dell and others. Apple has one sale a year on the day after Thanksgiving, Black Friday. Apple does offer Education and Refurbished deals. Some Apple resellers offer minor deals, especially on older products.

If you like running Windows 7 or 8, you unfortunately need a utility like this to stop Microsoft from nagging you or automatically upgrading without your permission.
