If you are writing a Bash shell script, you should read command-line arguments into an array for some time. This allows us to process any number of arguments provided when the script is run. This makes the script adaptable to different use cases. Instead of dealing with fixed variables like $1, $2, $3, etc., you can work with any number of arguments more dynamically using bash for loop or bash while loop, depending upon your needs. Arrays make it simple to loop through each argument and perform operations on them, whether basic printing or complex processing. Bash provides a mapfile (readarray command) internal built-in command to read lines from a file into an array variable. Let us see how to use mapfile to read all command line arguments into an array.

CentOS, RHEL (Red Hat Enterprise Linux), Fedora and other clones of RHEL, such as Oracle, Alma, and Rocky, offer support for version pinning. This feature allows developers and system administrators to lock a particular package to a specific version, preventing it from being automatically updated by yum or dnf commands. Sometimes, it is necessary to protect packages from being updated to newer versions to avoid incompatibility issues with your applications. For example, you can lock down PHP version 8.3.6 and avoid using updated PHP version 8.4. Let us see how to lock a package to a specific version, only exclude a package from yum update or dnf update on a CentOS, RHEL, Fedora, and friends.

Here's a quick tip for vim users. You can perform find and replace operations within a visual selection in Vim for text or code block. Visual selection for finding and replacing text in Vim allows developers and Linux/Unix users precise and efficient text editing.

Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

An anonymous reader shares a report: Speaking during an earnings call on Tuesday, CEO Lisa Su stated that its development of Microsoft's next-gen Xbox SoC is "progressing well to support a launch in 2027." While the comment doesn't outright confirm the next Xbox will release next year, it indicates that the Microsoft could be ready to launch soon.

BrianFagioli writes: Google has quietly retired the ZetaSQL name and rebranded its open source SQL analysis and parsing project as GoogleSQL. This is not a technical change but a naming cleanup meant to align the open source code with the SQL dialect already used across Google products like BigQuery and Spanner. Internally, Google has long called the dialect GoogleSQL, even while the open source project lived under a different name. By unifying everything under GoogleSQL, Google says it wants to reduce confusion and make it clearer that the same SQL foundation is shared across its cloud services and open source tooling. The code, features, and team remain unchanged. Only the name is different. GoogleSQL is now the single label Google wants developers to recognize and use going forward.

Vanguard just announced a new round of expense ratio drops spanning 53 funds (roughly 25% of them), totaling close to $250 million in fee reductions in 2026. See their press release and full list of changes. This comes almost exactly a year after their February 2025 cuts which spanned 87 funds with an estimated $350 in fee reductions that year.

Over the past two years, Vanguard has reduced fees on most of its fund lineup totaling nearly $600 million in savings for investors—Vanguard’s largest-ever two-year combined cost reduction. Vanguard’s product lineup across all asset classes and styles now has an average expense ratio of 0.06%, reinforcing the firm’s longstanding cost leadership position. These consistently low costs help investors keep more of their returns, contributing to stronger long-term performance.

Additional media coverage at the Wall Street Journal (gift article) and Morningstar.

At this point, most of their expense ratios are so low on their big funds that most individual investors won’t notice much of a difference. The largest index funds VTI, VXUS, BND are unchanged. Target Retirement funds are also unchanged. However, I do believe it is an important indicator that Vanguard is still lowering costs as their assets under management continue to grow.

As an individual investor, it’s also important to remember that costs matter and those costs directly affect performance. Jack Bogle was right in his past skepticism of ETFs in that over time, the group has grown to include a lot of complex, expensive options. While the overall, asset-weighted average expense ratio for ETFs has declined over time, the average fee of newly launched ETFs has actually increased. Be wary of all those new, fancy ETFs that make attractive promises like limited downside and extremely high dividend income. This “Boomer candy” almost always comes with a higher expense ratio, and I am willing to bet it will also end up with lower long-term returns. New tricks, same old story.

Personally, I note that the Vanguard 0–3 Month Treasury Bill ETF (VBIL) lowered its expense ratio from 0.07% to 0.06%. My current go-to is iShares 0-3 Month Treasury Bond ETF (SGOV), which is at 0.09%.

The 30-day median bid/ask spread on VBIL is now 0.01% of market price, meaning its liquidity is now basically on the same level as SGOV (also at 0.01%). I will probably start using VBIL instead of SGOV for the times when I want a short-term cash equivalent in a brokerage account. 0.03% is a small difference, but I gotta keep incentivizing those lower costs. Long live the Vanguard Effect!
