You Might Still Be Making These 7 Mistakes on Facebook

https://static1.makeuseofimages.com/wordpress/wp-content/uploads/2024/10/a-person-using-facebook-on-their-smartphone-with-warning-icons-in-the-background.jpg

Social media platforms like Facebook are excellent for connecting with people online, but it’s important to be cautious. Here are some common mistakes you might be making on Facebook without even realizing it.

1 Oversharing About Your Personal Life

While it’s natural to want to connect with friends and family by sharing updates about your life, revealing too much information can compromise your privacy and security. Sharing things like your location, daily routines, or family information can expose you to potential privacy breaches.

This information can be exploited by hackers, stalkers, or even advertisers seeking to target you more aggressively. For example, posts about vacations can signal to potential burglars that your home is empty, significantly increasing the risk of a break-in. Additionally, sharing real-time updates can inadvertently inform malicious actors of your whereabouts, leaving you vulnerable.

It’s best to limit the details you share about your daily life. Consider curating your posts and keeping sensitive information for private conversations rather than sharing it publicly.

2 Including Excessive Details in Your Bio

It’s not just about what you post; it’s also important to reflect on the details you’ve included in your bio and how much information you’ve shared there. You may have unwittingly disclosed excessive personal details, such as phone numbers, email addresses, significant life events, and intimate family information.

It’s crucial to remember that your Facebook profile may be visible to strangers, especially if your privacy settings aren’t properly configured. This level of openness can leave you vulnerable to harassment or unwanted contact from individuals with ill intentions. Personal information is also used in spear phishing scams.

Rather than sharing sensitive information in your bio, consider offering a concise overview of your interests, hobbies, or professional background. This will allow you to convey your personality without compromising your privacy.

3 Spreading Misinformation or Unverified News

These days, social media platforms like Facebook serve as major sources of news and information for many. However, the ease of sharing content has also contributed to the widespread dissemination of misinformation and unverified news.

When you share articles, memes, or posts without verifying their accuracy or understanding their sources, you may unintentionally contribute to the spread of misinformation. This can be especially harmful, as misinformation has the potential to incite panic, shape public opinion, and even influence elections.

To combat this, it’s essential to verify the credibility of any information before sharing it. Engaging critically with what you read helps prevent the spread of misinformation and contributes to a more informed community. Every post you share has the potential to influence others, so ensure that the message you’re amplifying is accurate and valuable.

4 Engaging in Toxic Discussions or Trolling

Facebook is a platform designed for connection, yet it often becomes a battleground for toxic discussions and trolling. What may seem funny or harmless to you can be offensive or hurtful to others. It’s important to understand that engaging in heated debates or making sarcastic comments can escalate tensions and contribute to a hostile environment.

Toxic discussions not only damage relationships but can also tarnish your online reputation. Once words are typed and posted, they can spread rapidly, leaving a permanent mark on your digital footprint. Consider whether your words will contribute to a healthy dialogue or simply escalate tension. After all, social media should be a space for connection and understanding, not conflict and division.

5 Allowing Your Profile to Be Discoverable by Search Engines

By default, your Facebook profile is discoverable through search engines. This means that anyone can find your account simply by typing in your name in a Google or Bing search. While this may seem harmless, it can compromise your privacy and security. Strangers or unwanted acquaintances can easily locate your profile and gather personal information that could be used for malicious purposes.

Even if you believe your privacy settings are strict, search engine visibility can undermine those protections. Search engines index your information regardless of your privacy preferences, which can expose you to unwanted friend requests, harassment, or even identity theft.

To avoid this, it’s best to make your Facebook profile unsearchable via search engines. For that, open Facebook and head to Settings & privacy > Audience and visibility > How people find and contact you. Then, turn off the toggle next to Do you want search engines outside of Facebook to link to your profile.

6 Failing to Adjust Critical Privacy Settings

One of the most significant mistakes Facebook users make is neglecting to adjust their privacy settings. Sticking with the default settings often allows broader access to your profile and posts than you might realize.

For instance, by default, Facebook allows anyone—regardless of whether they are friends—to view your friends list, bio, and the pages you follow. This can lead to unintended exposure of personal information to strangers, increasing the risk of privacy breaches.

Moreover, you may not realize that your posts can be visible to the public, depending on your settings. Even seemingly innocent information can be misused by malicious actors. Therefore, it is essential to take the time to enhance your Facebook profile’s privacy by manually adjusting the privacy settings or using the Privacy Checkup tool.

7 Overlooking Essential Account Security Measures

Keeping your Facebook account secure may not seem important, but it’s crucial for protecting your personal information and online identity. One common oversight is failing to enable two-factor authentication (2FA). Without it, your account is more vulnerable to unauthorized access, especially if your passwords are weak or reused across multiple platforms.

Over time, you may have unknowingly granted third-party apps and websites access to your Facebook account. These apps often require permissions that extend beyond what is necessary for their functionality, making it essential to regularly audit and manage these permissions. By taking a few moments to reassess what apps have access to your account and limiting permissions where possible, you can significantly enhance your data security.

In the fast-paced world of social media, it’s easy to fall into the trap of making mistakes, from oversharing personal information to neglecting privacy settings. However, by being aware of these common missteps, you can take proactive steps to enhance your Facebook presence and use the platform more effectively.

Optimize Your SQLite Database with the Laravel Optimize DB Package

The Laravel Optimize DB package provides a good starting point for production-ready SQLite databases. Pest creator and core Laravel team member Nuno Maduro created this package.

This package is meant for SQLite (3.46+) in a Laravel project and works by applying migration to your project and runtime configuration applied via the package’s service provider. It applies the following settings at the time of writing:

 ┌───────────────────────────┬─────────────┬───────────┐
 │ Setting                   │ Value       │ Via       │
 ├───────────────────────────┼─────────────┼───────────┤
 │ PRAGMA auto_vacuum        │ incremental │ Migration │
 │ PRAGMA journal_mode       │ WAL         │ Migration │
 │ PRAGMA page_size          │ 32768       │ Migration │
 │ PRAGMA busy_timeout       │ 5000        │ Runtime   │
 │ PRAGMA cache_size         │ -20000      │ Runtime   │
 │ PRAGMA foreign_keys       │ ON          │ Runtime   │
 │ PRAGMA incremental_vacuum │ (enabled)   │ Runtime   │
 │ PRAGMA mmap_size          │ 2147483648  │ Runtime   │
 │ PRAGMA temp_store         │ MEMORY      │ Runtime   │
 │ PRAGMA synchronous        │ NORMAL      │ Runtime   │
 └───────────────────────────┴─────────────┴───────────┘

High Impact Settings

I won’t cover each setting, but the following three settings could potentially have a highly positive impact on SQLite performance.

journal_mode = WAL:

  • Why it’s beneficial: Write-Ahead Logging (WAL) is one of the most effective ways to improve concurrency and performance in SQLite, especially for applications that need to support multiple readers and writers. It allows the database to handle many reads simultaneously while still maintaining atomicity and durability for writes.
  • Use case: Great for databases with mixed read/write workloads and high concurrency requirements.

cache_size = -20000 (20 MB cache):

  • Why it’s beneficial: Increasing the cache size helps store more pages in memory, reducing the need for disk I/O. This is especially useful for databases that are read frequently or have hot data. A larger cache means fewer page reads from disk, resulting in faster query responses.
  • Use case: Important when dealing with large datasets and you have sufficient memory resources available.

mmap_size = 2147483648 (2 GB memory mapping):

  • Why it’s beneficial: Memory-mapping the database file can dramatically improve performance by reducing the overhead associated with file system operations. It allows the database to access data directly in memory, bypassing the need for repeated system calls to read or write data.
  • Use case: Very beneficial for large databases on systems with ample memory, where file access speed is a priority.

The package is considered a work-in-progress, so use it carefully. The package advises not to use it in production yet and to back up your database before requiring it. You can learn more about this package and view the source code on Github.

How Mossad Planned Its Exploding Pager Operation: Inside Israel’s Penetration of Hezbollah

The Washington Post interviewed Lebanese officials, people close to Hezbollah, and Israeli, Arab and U.S. security officials and politicians about a years-long plan (originated at Mossad headquarters) that ultimately killed or maimed "as many as 3,000 Hezbollah officers and members — most of them rear-echelon figures… along with an unknown number of civilians… when Israel’s Mossad intelligence service triggered the devices remotely on September 17."
In the initial sales pitch to Hezbollah two years ago, the new line of Apollo pagers seemed precisely suited to the needs of a militia group with a sprawling network of fighters and a hard-earned reputation for paranoia… Best of all, there was no risk that the pagers could ever be tracked by Israel’s intelligence services. Hezbollah’s leaders were so impressed they bought 5,000 of them and began handing them out to mid-level fighters and support personnel in February. None of the users suspected they were wearing an ingeniously crafted Israeli bomb… Israeli officials had watched with increasing anxiety as the Lebanese group added new weapons to an arsenal already capable of striking Israeli cities with tens of thousands of precision-guided missiles. Mossad, the Israeli intelligence service responsible for combating foreign threats to the Jewish state, had worked for years to penetrate the group with electronic monitoring and human informants. Over time, Hezbollah leaders learned to worry about the group’s vulnerability to Israeli surveillance and hacking, fearing that even ordinary cellphones could be turned into Israeli-controlled eavesdropping and tracking devices. Thus was born the idea of creating a kind of communications Trojan horse, the officials said. Hezbollah was looking for hack-proof electronic networks for relaying messages, and Mossad came up with a pair of ruses that would lead the militia group to purchase devices that seemed perfect for the job — equipment that Mossad designed and had assembled in Israel. The first part of the plan, booby-trapped walkie-talkies, began being inserted into Lebanon by Mossad nearly a decade ago, in 2015. The mobile two-way radios contained oversized battery packs, a hidden explosive and a transmission system that gave Israel complete access to Hezbollah communications. For nine years, the Israelis contented themselves with eavesdropping on Hezbollah, the officials said, while reserving the option to turn the walkie-talkies into bombs in a future crisis. But then came a new opportunity and a glitzy new product: a small pager equipped with a powerful explosive. In an irony that would not become clear for many months, Hezbollah would end up indirectly paying the Israelis for the tiny bombs that would kill or wound many of its operatives. Because Hezbollah leaders were alert to possible sabotage, the pagers could not originate in Israel, the United States or any other Israeli ally. So, in 2023, the group began receiving solicitations for the bulk purchase of Taiwanese-branded Apollo pagers, a well-recognized trademark and product line with a worldwide distribution and no discernible links to Israeli or Jewish interests. The Taiwanese company had no knowledge of the plan, officials said… The marketing official had no knowledge of the operation and was unaware that the pagers were physically assembled in Israel under Mossad oversight, officials said… In a feat of engineering, the bomb component was so carefully hidden as to be virtually undetectable, even if the device was taken apart, the officials said. Israeli officials believe that Hezbollah did disassemble some of the pagers and may have even X-rayed them. "Thousands of Apollo-branded pagers rang or vibrated at once, all across Lebanon and Syria," according to the article, with a short sentence in Arabic that said "You received an encrypted message." The two-button de-encryption procedure "ensured most users would be holding the pager with both hands when it detonated," according to the article, although "Less than a minute later, thousands of other pagers exploded by remote command, regardless of whether the user ever touched his device. The following day, on September 18, hundreds of walkie-talkies blew up in the same way, killing and maiming users and bystanders…" "As Hezbollah reeled, Israel struck again, pounding the group’s headquarters, arsenals and logistic centers with 2,000-pound bombs," the article concludes. And the strike "convinced the country’s political leaders that Hezbollah could be put on the ropes, susceptible to a systematic dismantling using airstrikes and, eventually a ground invasion…"

How to make an external bootable drive in macOS Sequoia

https://photos5.appleinsider.com/gallery/61263-126550-IMG_9785-xl.jpg

All of these drives can get Sequoia. Here’s how.


Apple makes it harder to make an external boot drive for your Mac than it has in the past, but sometimes you still need to do it. Here’s how to do it in macOS Sequoia.

Apple Silicon and macOS may be excellent, but when a Mac won’t start up, having the option to boot from an external drive is key. It will help with diagnosing the problem, and at worst it can mean your being able to carry on working after just a few minutes.

Being able to boot up any Mac from an external drive you happen to have with you is a potential security risk, though, and Apple is not having that. You now have to make a deliberate, positive choice to disable an element of macOS security in order to even start.

Take extreme care

Not only will you be actively turning off a security feature, you’ll also have to erase the external drive you want to boot from. You know that accidentally erasing your Mac’s own internal drive would be disastrous, you know you wouldn’t do that deliberately.

Yet despite that and despite the Mac double-checking you mean what you’re doing, it is still possible to make a mistake.

Consequently, the short answer to how you make a bootable external working drive is very, very carefully — and only after you’ve backed up everything.

You’ve simply got to make a backup of anything on the external drive that you want, because that’s all going away. It isn’t strictly necessary to back up your Mac’s internal drive, but do it anyway.

Use Apple’s Disk Utility to format the external drive

Maybe you’ll just have a spare copy of your data, but maybe that spare copy will be what you need to get back to work.

Then the job entails two steps:

  1. Allowing your Mac to boot from external drives at all
  2. Preparing a bootable external drive

That first part is crucial, and it is crucial that you do it before you have any problems. If you need to boot from an external drive because your Mac won’t start up, you’ve got to have already done this step because there’s no way to do it later.

So while your Mac is fine, take a few minutes to do this enabling of external drives. If you’re still on an Intel Mac, the process is different, but for all Apple Silicon Macs you have to go through these same steps.

How to allow external startup drives on Apple Silicon Macs

  1. Shut down the Mac
  2. Press the power button and keep it pressed
  3. Let go when you see one or more drives and an Options section
  4. Select Options and click Continue
  5. When the Mac boots into Recovery Mode, select a Mac user you know the password for
  6. Log in as that user
  7. Ignore all of the options in the pop-up list and instead choose Startup Security Utility from the Utilities menu
  8. Click to select the Mac’s internal drive and then click Unlock
  9. Follow the prompts concerning passwords, and select Security Policy
  10. In the Security Policy window that appears, click to select Reduced Security
  11. Then click OK
  12. Under the Startup Disk menu at top left of your screen, choose Shut Down

Now your Mac is ready. You can plug in an external drive to start up from it — except you now need to prepare that drive.

How to create an external, bootable work disk with macOS Sequoia

Not every external drive will do, but most will. The ones to ignore are the cheapest flash drives, though, as this works even with many USB sticks.

The external drive should preferably be a fast one. It definitely has to be a single drive — you can’t start up your Mac by plugging in any kind of RAID array of drives.

You can use a spinning hard drive, and those are available cheaply. But this is something where you need reliability, so go for one of the current best external SSDs.

Be so careful to choose the right drive

And of course the drive has to have macOS Sequoia on it.

So next you format the drive, then you put the macOS installer onto it.

How to format an external drive on macOS Sequoia

  1. Connect your external drive to your Mac
  2. Open Disk Utility in Applications, Utilities on your Mac
  3. Carefully select the external drive from the list that appears
  4. Click on Erase
  5. Give the drive a name
  6. From the dropdown menus that appear, choose APFS
  7. Click on Erase

Under Apple Silicon, this is likely to take only moments. When it’s done, the drive is ready, and you can go get macOS Sequoia from the Mac App Store — but you need to look in the right place.

Even as Apple promotes a new macOS on the App Store, it may not give you a link to a downloadable installer. Instead, search the Mac App Store for "macOS Sequoia," and you’ll find it.

From the list of search results that appears, click on View, then when you see it, Get. Important — it’s going to look exactly as if you’re about to install macOS Sequoia on your Mac’s internal drive, but you are not.

It looks like that because you are bounced from the App Store to the Settings app, and its Software Update section. After a few moments, however, a popup asks whether you want to download the OS. Click on the Download button to say yes.

Don’t think you can go make coffee and lunch, the time remaining is an estimate that tends to be overly cautious

Once it is downloaded, then you are prompted to install. While that is what you want, take a moment first to find the installer in the Finder. It will be called "Install macOS Sequoia" and is about 14.5GB is size.

Find it and make a copy somewhere. If you later want to install macOS Sequoia on different Macs, or if you just need to start again with your current one, it’s handy to have that file available.

Nonetheless, you downloaded it to install it on your external drive and assuming that drive is now formatted, you can just follow the prompts. Be certain, though, be absolutely certain, that you have selected that external drive first.

The next step takes several minutes, although you have nothing to do during that time but wait. When it’s ready, the Mac will ask you to restart it and will also caution that it may then restart itself several times.

You now have an external startup disk with macOS Sequoia on it

In theory, you’re finished now, but in practice installing a copy of macOS anywhere sets the Mac off asking you questions. It will try to prompt you through questions about location, Siri, and so on.

It will try very hard, but you don’t need to answer everything. While Apple seems to have made this deliberately hard to spot, there will always be a "Set Up Later" or similar button somewhere on the screen.

You may find that your fresh, new installation of macOS Sequoia on the external drive abruptly launches the same macOS Sequoia installer. Just quit it.

What to do next

You made this drive bootable for a reason, and whether that’s because you suspect a particular problem, or you just want to be careful, you need to do one thing next. You need to startup the Mac from this drive, just to be certain that it works.

It almost certainly will. The only possibility where it might not is if there is an issue with the external drive.

Typically that means there’s a fault or that the drive isn’t fast enough. What you’ll almost certainly find is that even when it works, though, the external drive will not be as fast as your internal one.

The result is that you’ll feel your Mac is slower. It’s possibly Apple’s way of saying you need to get that internal drive fixed sharpish.

Assuming that you can put up with a slower Mac if it means you can carry on working, you do also need to make sure that you have the tools you need to do that work. So while it’s probably not worth copying everything over from your Mac to this drive, at least make sure that the major applications you use are there.

With a slower Mac and perhaps not all of your applications available, booting from an external drive is a compromise. But it’s a compromise we need in order to fix problems or work around them.

So it’s good that Apple has made it so that by default, random strangers can’t boot your Mac from their drive. But it’s a relief that Apple hasn’t made it impossible for us to — as long as we prepare in advance.

Safety First

Before diving into specific malfunctions, it’s important to emphasize the need for safety. If your AR-15 doesn’t fire as expected, remove your finger from the trigger and ensure the firearm is pointed in a safe direction. Avoid attempting to force the weapon to function. Instead, take a moment to assess the situation calmly. With experience, diagnosing and clearing malfunctions will become second nature, but taking it slow and steady is the safest approach for now.

Before we get into the list of the most common malfunctions, check out the following video by Pat McNamara on handling the most common rifle malfunctions. He breaks it down into an easy-to-understand format that everyone can understand.

Failure to Feed (FTF)

Failure to Feed (FTF) is one of the most common malfunctions encountered by AR-15 users. It occurs when a round from the magazine fails to load into the chamber. This malfunction can happen unexpectedly, whether it’s the first shot of the day or midway through a magazine. The good news is that most failure-to-feed issues are straightforward to diagnose and resolve.

Quick Fix:

Tap, Rack, Reassess: Tap the magazine to ensure it’s seated, rack the charging handle to chamber a round, and reassess the rifle’s readiness to fire. If the problem persists, switch out the magazine and check for worn-out springs or bent feed lips.

Preventative Tip: Regularly inspect your magazines. For reliable performance, consider using trusted options like Magpul Gen 3 PMAGs or D&H metal magazines. Why these? The D&H mags don’t just stand up to the challenge; they’re built for it, with anti-tilt followers and a gray Teflon finish that withstands temperature changes and environmental challenges like a champ.

As a Marine infantryman, I’ve carried the M16/M4 across the globe and fired thousands of rounds through them. This experience hasn’t just made me a better shooter; it’s shown me firsthand how often gear can fail, especially magazines. Most malfunctions? They came down to issues with the mags—worn out from use, bent feed lips, damaged followers, or springs that just couldn’t cut it anymore. The fix was usually simple: swap out the faulty magazine. More often than not, that was all it took to get back in action.

Failure to Eject/Extract (FTE)

Failure to Eject (FTE), also known as a “stovepipe” malfunction, occurs when the empty cartridge case of a fired round fails to exit the chamber and gets stuck, usually protruding from the ejection port. Similarly, a Failure to Extract happens when the bolt successfully extracts the spent casing from the chamber but fails to eject it completely, leaving it trapped in the rifle. Both types of malfunctions prevent the next round from being chambered.

Quick Fix:

Immediate Action: Lock the bolt to the rear, drop the magazine, and tilt the rifle to shake out the casing. If stuck, use a cleaning rod to push it out from the muzzle.

Preventative Tip: Regularly clean your bolt carrier group and chamber to prevent carbon buildup. Ensure the extractor and ejector springs are in good condition.

Failure to Fire (FTF)

Failure to Fire (FTF) occurs when the shooter pulls the trigger, but instead of the expected “bang,” there is only a disappointing “click.” This malfunction can be caused by various factors, ranging from ammunition issues to mechanical problems within the rifle. This includes rounds with improperly seated bullets, damaged casings, or bad primers.

Understanding the root causes of FTF and how to address them can save time and prevent unnecessary frustration at the range or in a critical situation.

Quick Fix:

Eject the round and check the primer for a light or absent strike.

Reload and chamber a new round. If the rifle still doesn’t fire, inspect the bolt and firing pin for damage or dirt buildup.

Preventative Tip: Use quality ammunition and keep your rifle clean and lubricated to ensure reliable firing.

Over-Gassed and Under-Gassed Rifles

Whether your AR-15 is over- or under-gassed, gas system issues can lead to a range of malfunctions that affect your rifle’s reliability and performance. Understanding the symptoms and causes of each condition is crucial for diagnosing and resolving related malfunctions effectively.

Over-gassed symptoms: Harsh recoil and failure to eject properly.

Under-gassed symptoms: Failure to lock the bolt back or weak ejection.

Quick Fixes:

Over-Gassed: Install an adjustable gas block or use heavier buffers and springs to slow down the cycling.

Under-Gassed: Check gas block alignment and use higher-quality ammunition. You may also need to switch to a lighter buffer and spring.

Preventative Tip: Keep your gas system clean and consider using an adjustable gas block to fine-tune the system for your ammo and shooting conditions.

Double Feeds

A double feed occurs when two rounds attempt to enter the chamber simultaneously, causing a jam. This usually happens when a live round is stuck behind a previously fired round or its empty casing. Faulty magazines, weak springs, or extractor and ejector failures can cause double feeds.

Quick Fix:

Drop the magazine, lock the bolt to the rear, and use your fingers or a tool to remove the obstructing rounds. After clearing the jam, insert a fresh magazine and cycle the bolt.

Preventative Tip: Ensure your magazine springs are strong and avoid overloading your magazines to reduce tension-related failures.

Bolt Override

A bolt override is a rare but serious malfunction where a live round or spent casing gets stuck above the bolt and below the charging handle. This type of jam can be particularly challenging to clear.

Quick Fix:

Drop the magazine, pull the charging handle back, and lock the bolt to the rear. While keeping pressure on the charging handle, strike the butt of the rifle on a hard surface to dislodge the obstruction.

Preventative Tip: Ensure your ejector and extractor are functioning properly and keep your rifle clean to avoid buildup that could lead to a bolt override.

Stovepipe Malfunction

A stovepipe malfunction, named for how the spent casing sticks vertically out of the ejection port like a stovepipe, occurs when the empty casing fails to fully clear the rifle during ejection. This can disrupt the cycle of operations and prevent the next round from being chambered. Although stovepipes are relatively easy to fix, repeated occurrences can indicate underlying issues that need to be addressed.

Quick Fix:

To eject the casing, perform the “tap, rack, reassess” drill. If it’s still stuck, manually lock the bolt to the rear and clear the obstruction.

Preventative Tip: Keep your rifle clean, especially the bolt carrier group, and ensure your ejector functions correctly. If this happens frequently, consider upgrading your ejector spring.

Conclusion

Experiencing these AR-15 malfunctions can be frustrating, but understanding the most common issues and how to address them will help you become a more proficient and confident shooter. Regular maintenance, proper cleaning, and using quality components are key to minimizing these malfunctions.

From failure to feed to stovepipe malfunctions, each issue has specific causes and solutions. By familiarizing yourself with these troubleshooting techniques, you can quickly diagnose and clear malfunctions, ensuring your rifle remains functional.

Longer Battery, Better Tracking, Improved Fit: Halo Collar 4 Review

https://s3.us-east-1.amazonaws.com/images.gearjunkie.com/uploads/2024/09/IMG_R_0098.jpg

The peace of mind that comes with knowing your dog is safe is almost invaluable. I should know. I currently have 11 dogs. Each of them has some kind of collar that best suits their sport, personality, and temperament.

I’ve not hidden my love of Halo GPS dog collars. I’ve used just about every major “wireless fence” style dog collar on the market, and the Halo collars have yet to let me down. Where other collars have failed and left me searching for one of my bird dogs for several days, the Halo Collars have stepped up and always filled the role of reliable, consistent, and user-friendly.

When I heard the Halo Collar 4 was coming out, I assumed it would be much the same when I agreed to test it. I was wrong. Not only does it sport a smaller frame and hinged component, making it far more comfortable for a pup, but it’s also compatible with dogs half the size of its predecessor (from a 20-pound minimum size down to 20-pound pups).

The biggest claim is the jump in battery life. You can go ahead and color me skeptical when a brand makes bold battery life claims. So, did it measure down and battery up as much as the brand claims?

In short: Skepticism be damned. The Halo Collar 4 ($599) outperforms its predecessor in every way, which is a tough feat to conquer. The battery life is wild and, in my tests, actually goes above and beyond what the company claims.

Halo Collar 4 Review

  • Dual-frequency GPS collar
  • Fits dogs 10 lbs. and up with neck sizes from 8" up to 30.5"

What Halo Has to Say About the Newest Addition to the Lineup

If we’re going to start anywhere, let’s start with cofounder Cesar Millan. I want you to picture the following quote in his voice. It makes it better, I promise.

“Halo Collar 4 allows pet parents to set rules, boundaries and limitations while creating a backyard everywhere they go. You can now provide trust, respect and love to your dog knowing they are safe wherever they go.” 

— Halo Cofounder Cesar Millan

The Halo Collar 4 promises a lot. I’m going to do something I rarely do and copy the intro to the press release here verbatim (with a few Oxford commas added because I have editorial integrity).

Halo, the most advanced GPS dog fence ever created, is launching the Halo Collar 4, the first collar designed to fit big and small dogs, giving pet parents the ability to create a “backyard” everywhere they go. It is the first and only dual-frequency GPS dog fence for unrivaled accuracy that combines data from L1 and L5 GPS bands for the most accurate location that is not impacted by obstacles, even in urban or bad signal areas. 

Halo Collar 4 also offers the perfect fit for big and small dogs with a tailoring system that lets you custom fit the collar to your dog’s exact neck size from 8 inches to 30.5 inches. The updated rendition includes 25% more battery life for 30+ hours between charges, a smaller and lighter all-day fit, and comes in a new Midnight Blue color, as well as updated Graphite, Orchid, and Sunburst colors.

Those are some hefty claims that I was borderline excited to bust.

Testing the Halo Collar 4

The Trainee

The thing about bird dogs from a strong hunting line is this: when bird season rolls around, a young bird dog can be almost impossible to keep contained when birds are about. My youngest Brittany is that dog. At a year and a half old, she knows her duty is to hunt ’em up. She does not, however, practice much restraint when she isn’t supposed to hunt ’em up. Known for having boundless energy, she measures up in all the best and worst ways that her breed has to offer.

Enter the true challenge for the Halo Collar 4. Even when faced with rooster pheasants at the edge of her perimeter, the Halo collars have kept her contained without the need for static shock or human intervention. She’s learned her tones and learned that it’s only when the collar comes off and the shotgun comes out that she can take to the field.

Battery Life to the Moon

After testing two previous version of the Halo collars, I wasn’t sure I’d see much benefit with the newest iteration. And then the battery life jumped up and smacked me in the face.

I run the Halo Collar 2 and Halo Collar 3 on another Brittany and a German shorthair. Both those collars give me a day of battery life. When I say a day, I mean a daylight day. Depending on how rowdy the pups get, I see anywhere from 8 to 12 hours of consistent battery life. That means they are contained for the work day and a bit after. Each night, the collars get plugged in when the pups get tucked into bed.

The Halo Collar 4 has run for 2 full days with no charge and held battery life the entire time. Yes, while at home, it still gets plugged in every night. However, this means a weekend away in the mountains requires no additional draw on the power banks I rely on. That leap in battery life is huge for those who overnight sans power in the great outdoors.

What the Halo Collar 4 Does Well

Everything it claims to. If you need a reliable GPS dog collar to keep your pup contained without fences, this collar will do it and do it well. If you have a pup that is too small to wear most GPS collars, this one might be the ticket.

I love being able to sit at my desk and look at the exact location of my pups on my phone. They don’t have to be penned up when I’m not looking. They can roam and play and be dogs, all while I know they are safe and secure. I’m not a fan of putting up fences for a heap of reasons, and this allows me to keep the landscape natural and my dogs safe.

The App

Halo App

The Halo Collar App is another huge win for Halo. I’ve used other digital-fence-style collars with apps that made me want to throw my phone out the window. The Halo app is user-friendly, intuitive, clean, and simple to use. I can open my phone, see where my dogs are, and even whistle at them to come home. The app is top-notch in the world of GPS collars.

It also has a full dog training module taught by none other than Cesar Millan himself.

Always On

This is a big one. If your collar dies and you stick it on the charger, it turns itself back on. You don’t need to hold the power button for 30 seconds, rub your belly six times, and spin in a complete circle to get the collar to turn on and connect to the app. That might seem silly, but I’ve used other collars that are a pain in the royal arse to get reconnected to your phone, and I was never certain whether the collar was even on.

The Halo Collar 4 (and its previous versions) turns itself on and automatically connects to the app, ensuring immediate protection for your pup by just grabbing it off the charger and snapping it on. It’s grab-and-go protection that has never let me down.

Where’s the Downside?

You could say that they’re expensive, but they really aren’t. The Halo Collar 4 is at or below the cost of almost any other big-name GPS collar at $599.

The Charger

What you could complain about is the charger, but that’s only if you have former versions of the collar. I have three different versions, and each one has a different charger. That is frustrating, but I do get it. The newer versions likely require a bit more oomph, so they likely require a heftier charger.

That being said, a universal USB-C charger would be a huge perk, especially if you’re on the go and don’t have your collar-specific charger handy. Only my oldest Halo Collar offers that option.

A Little Lag

This is one that I guess can be expected. Occasionally, depending on weather or tree cover, you might experience a little lag in GPS connection. I always try to open my app when I send the pups outside, just to make sure they’re connected and covered. That being said, the lag is absolutely minimal, particularly when compared to other GPS collars.

Who Should Buy the Halo Collar 4?

Anyone interested in knowing where their canine companion is without going to the window or walking outside should consider the Halo Collar 4. This collar is perfect for anyone who lives near a busy road or can’t put up a fence. It’s the solution for weekend warriors who need to keep their pup at camp and out of the far-reaching mountains.

To be honest, I’m not sure who the Halo Collar 4 wouldn’t be good for. If you have a dog that weighs 10 pounds or more, you would benefit from adding it to your pup’s accessories. Period. End of story. They rock.

One of the other perks is that I bet the Halo Collar 3 is about to go on sale. So … you know, getcha one of those, too.

If you can’t tell, I stinkin’ love mine.

The History of PKM, the Most Common Machine Gun In the World (Part 1)

https://cdn-fastly.thefirearmblog.com/media/2024/09/16/10061/the-history-of-pkm-the-most-common-machine-gun-in-the-world-part-1.jpg?size=720×845&nocrop=1

Everyone knows AK-47. It is everywhere: movies, books, crime statistics. Interestingly enough, those who spend some time in the warzone often have stronger feelings towards another Kalashnikov creation – the PK/PKM belt-fed machine gun.

Some say that PK is the best weapon Kalashnikov ever created. While AK was developed at the very beginning of his career, PK was created when Kalashnikov had plenty of experience.

Millions of those machine guns are used all over the world, US special forces requested American companies to produce those guns multiple times, and some experts call it “the best general purpose machine gun”.

However, few people know that it was created almost by accident. There are many great articles on AK history, but there is almost nothing published in English about the PK development, and hopefully, this article can fix that.

One of many PKMs the author inspected and repaired in Afghanistan

How it all started

The summer of 1959 was a busy time for Mihail Kalashnikov. The new family of weapons he designed, which included AKM and RPK light machine guns, was just getting into production. He had to prove for the second time in his career that his rifle was the best.

First, his AK 47 won the competition in 1949, and ten years later his other creation, AKM bested all rivals and now was destined to become the new service rifle of the Soviet Army and most Warsaw Pact countries.

Kalashnikov hadn’t had a vacation in 4 years. That summer there was finally an opportunity to celebrate, and it was all more convenient that his old friend visited him in the city of Izhevsk.

Vladimir Deikin and Mihail Kalashnikov

The old friend was army officer Vladimir Deikin, who was one of the people who made AK happen. The officer of GRAU, the military department responsible for procurement of new weaponry, he supported Kalashnikov all the way through the development of the original AK rifle, ruthlessly crushing bureaucracy and red tape that got in the way of a young weapon design engineer.

As the years went by, a young and shy Kalashnikov became the most respected weapon designer in the Soviet Union, and Vladimir Deikin became a colonel, rising to the top of the career ladder.

That summer two friends who have been through a lot could finally enjoy their life. They took a boat and went fishing, invited friends from the factory, and spent the weekend in a cabin on the lake, talking about guns and cooking fish they caught.

Before leaving, Vladimir Deikin nonchalantly shared some news: “This guy Nikitin at the factory in Tula is developing GPMG (general purpose machine gun). The trials are almost over, it adheres to the requirements… But in GRAU we think it is a little too complicated. The army needs something more simple”.

Prototype of the Nikitin GPMG

He didn’t ask Kalashnikov to get involved. He never asked for help. But he knew his old friend and realized, Kalashnikov won’t just leave it alone. Now, after his friend left, Kalashnikov had a whole bunch of questions.

Why wasn’t I asked to develop this new GPMG? Why don’t they trust me? Am I in trouble? How complicated is too complicated? Will they ask me to redesign this gun once it finishes trials? Or is it the end of my career?

The brainstorming

Kalashnikov decided that he must do something about it. He already had a team of engineers and enough authority to build a machine gun from scratch without asking permission.

There was no money allocated for this project, but he could pull some strings and use money from his other projects to finance the ammo and all the prototype building.

He became obsessed with his new machine gun and completed the first sketches in just ten days. However, drawings alone are no good, you need to make blueprints, which Kalashnikov couldn’t really do – he was never formally educated and always relied on someone else to make blueprints.

In this case, engineer Krupin was tasked with creating proper blueprints, and the entire team got on with the project. The rival machine gun from Tula was already undergoing troop trials, the Ministry of Industry never asked for another contender, but Kalashnikov decided that he would deal with that another day.

The obsession Kalashnikov had was contagious, engineers were staying at work until 5 in the morning, and within weeks they started making the first parts of the prototype.

Often, there was no time to make proper blueprints, so engineers just winged it, making parts on the lathe and milling machine relying solely on their imagination and some sketches.

Within a month, the first prototype of PKM was ready. Now Kalashnikov just had to convince the entire Soviet military-industrial complex that his crude prototype was better than a machine gun that already passed all the trials and ticked all the boxes. How did he manage to do that? That is the story for Part 2 of this article.

Triple Apple Charger/US Passport Changes/Designer Cities

A weekly newsletter with four quick bites, edited by Tim Leffel, author of A Better Life for Half the Price and The World’s Cheapest Destinations. See past editions here, where your like-minded friends can subscribe and join you.

Triple Travel Charger for Apple Devices

If you’re all-in on Apple products, you might like this 3-in-1 travel charger a reader recommended for your iPhone, watch, and Airpods. The folding magnetic charger is smaller than a phone but can charge up all three of these fast-fading devices every night so you can start fresh in the morning. Selling for $60 now at Amazon. (Thanks to reader Jim from the SpanishAndGo podcast, which I recommend by the way if you’re an intermediate learner.)

Two U.S. Passport Developments

Good news for U.S. passport holders this week. First of all, the State Department is leaping into the modern age and you can now renew your passport online after a successful beta text. Just don’t expect it to be any faster, they warn. Also, Google announced that it’s in beta tests to create a digital ID from your passport that you’ll be able to use at TSA checkpoints. They’re also adding driver’s licenses for many states and commuter cards for public transportation.

New UK Entry Fee

It’ll soon cost you the equivalent of a few pub pints to enter the UK—unless you’re Irish. Most countries will have to apply for and pay a fee of £10. For most travelers that begins in November, but for Europeans it will roll out in the spring. You’ll even have to cough up the fee for your lap baby as apparently this fee to fund enhanced security is required for them as well. This is separate from the upcoming ETIAS €7 fee to enter the EU, so you’ll pay twice if you’re going to both. See the details here.

Cities That Inspire Designers

Where do interior designers like to go when they’re looking for inspiration? This article from House Beautiful runs down 12 places that the people picking out sofas and curtains called out when asked. Some are a bit puzzling to me, but I’ve certainly seen hints of other named spots in Morocco, Colombia, Turkey, and Italy in restaurants and hotels in other places.
