Hands-On
The Sonnet eGFX Breakaway Puck packs a Radeon RX570 GPU inside a portable, Thunderbolt 3-compatible package, offering MacBook users a take-anywhere graphics boost.
With the release of macOS 10.13.4 last month, Apple’s desktop platform provides support for external GPU boxes over Thunderbolt 3. The handy hardware can provide a much-needed graphics boost to a variety of Macs, including MacBook Pro.
What really makes this external GPU different from others is its diminutive size. We’d even go as far as to say that it is portable.
To make the Puck so small in size, Sonnet used an external power supply that is nearly as big as the Puck itself. Our model contains a Radeon RX570, so we know that it is a relatively power hungry card.
The power supply is capable of handling up to 220W, which it can also use to provide up to 85W of power to a Mac at the same time.
There are two different flavors of the eGFX Breakaway Puck. One rocking a Radeon RX 560, the other with a Radeon RX 570. We are testing out the latter, as it seems the former isn’t Mac compatible. Interestingly, the Radeon RX 560 worked with early macOS High Sierra beta builds, but that compatibility ended when full support for eGPU technology officially rolled out.
Regardless, in either configuration, the GPUs both come with 4GB of VRAM on board.
Three DisplayPort 1.4 ports and a single HDMI 2.0 port make up the external connectivity. All of these outputs are capable of 4K at 60Hz, allowing even a two-port 13-inch MacBook Pro with function keys to have a quartet of monitors. Of course, it has a Thunderbolt 3 port onboard as well, which is used to connect to your Mac — but no downstream connector.
A power supply and an OWC Thunderbolt 3 cable are included in the box, with no additional cables necessary.
When looking at the size, the Puck box measures roughly 6 inches-by-5.12 inches, standing 2 inches tall. Easy to move about or hide on your desk.
It is so compact that we would believe someone if they told us it was simply an external hard drive. When looking closely, a few things reveal the fact it is an eGPU. Looking in the side grills you see several copper heat spreaders and heat pipes. When looking through the grill on top, you can see the large fan that is used to cool the card and VRAM.
Obviously, the bevy of ports around back also reveal its true nature.
It is a shame the power supply is so monstrous, but I think I prefer the eGPU’s small size over an integrated power supply. That way I can offload the power brick to below my desk, giving me more usable space on top.
The body is largely plastic, with a metal grill on the top. It still retains quite a bit of weight, however, lending a premium feel.
We will be putting this eGPU through more exhaustive tests for our full review, but in our limited time with it we have been quite pleased with the performance.
If you are eager to pick one up for yourself you can find the Sonnet Radeon RX570 eGFX Breakaway Puck on Amazon for $599.
Do you plan on picking up an external GPU? Let us know in the comments!

Arizona -(Ammoland.com)- Michigan Concealed Pistol License holders have an extremely low murder rate. Japan has a very low murder rate. Japan is also a very law-abiding culture.
The United States, as a whole, has a much higher murder rate than Japan. Within the United States, there is a law abiding culture that has a murder rate as low as Japan’s. That culture consists of gun owners who carry guns legally.
The FBI generally includes legally defined murder, which may be in the first or second degree, and non-negligent manslaughter, in the definition of murder for their statistics. A more precise definition might be “criminal homicide”.
In Michigan, the State Police are tasked with compiling crimes committed by people who have the Michigan Concealed Pistol License (CPL). The State Police Reports are available from 2003 to early 2017. The state police report list convictions of people for murder, and manslaughter, as well as a multitude of other offenses. From 2003 to 2017, there are 14 years of reports listing criminal convictions.
Criminal homicides are the most reliable crime statistics to track, and the most important for comparisons with other societies. While there are significant differences in definitions, reporting, and recording of crimes from nation to nation, murders, or criminal homicides, are more reliable than other crime statistics.
In the 14 years of Michigan annual police reports, there are 17 criminal homicide convictions recorded by the Michigan State Police (MSP), for people who had CPLs.
The number of active CPLs in Michigan for each year of the 14 annual reports was a little more difficult to find. The annual reports run from October 1 to September 30 of the following year. I found numbers in each annual report period, except for the period of October 1, 2014, to September 30 of 2015. For that period I interpolated from the March 2014 number of 430,000 to the November 2015 number of 488,000, to obtain 459,000. The numbers for the other years used were within the period for each report. Over the fourteen year span, a variation of a few months does not make much difference.
When looking at criminal homicide rates, the standard is to look at the number of homicides per 100,000 of the population per year. The total number of CPL – years came to 3,953,944. Over the 14 year period, individual CPLs had been active for a total of 3,953,944 years. There were 17 criminal homicide convictions of CPL holders in that period, averaging .43 criminal homicides per 100,000 CPL holders per year.
The entire Michigan population, over the same period, had an average of 6.2 criminal homicides per 100,000 people, or more than 14 times as many. Over the same period 2003-2016, the Japanese criminal homicide rate was .42 per 100,000 population.
Michigan Concealed Pistol Licenses are fairly easy to obtain. The same background check is used for the CPL as is used for ordinary people to buy from federally licensed dealers in the United States. The people with Concealed Pistol Licenses are not only able to own firearms but to legally carry them concealed and loaded with them nearly everywhere.
Yet, their criminal homicide rate is as low as the highly regulated Japanese.
International comparisons are always tricky. Many countries do not keep good statistics. Some countries actively ignore some murders to make their statistics look better. Others do not have the infrastructure to report and record crimes. Countries have different definitions of what a criminal homicide is.
In cases such as Michigan, the numbers of homicides among Concealed Pistol License holders is so tiny that it can vary enormously with just a few crimes. Fourteen years gives us a better picture, but it is still a small sample. There are five years with no convictions, five years with one conviction, two years with two convictions and two years with four convictions. The convictions do not mean the CPL holder used the CPL in the crime. They mean there was a criminal homicide conviction for someone with a CPL.
While not as well documented as the Michigan CPL, the Wisconsin CCW permit holders have a similarly low rate of criminal homicides. When I calculated the number in 2016, the criminal homicide rate for CCW permit holders in Wisconsin was .19 per 100,000. Wisconsin CCW permits are easier and cheaper to obtain than Michigan CPLs.
If, as those who wish a disarmed population claim, the mere presence of firearms makes criminal homicide more likely. How is it that those who not only own handguns but can legally carry them loaded most places, most of the time, have a criminal homicide rate as low as the Japanese?
Japanese culture is much more homogeneous than American culture. American culture has a wide diversity. Some subgroups, like American legal gun carriers, are very law abiding and responsible. Other American sub-groups are not. American culture is closer to an amalgam of world culture.
The world average intentional homicide rate was about 6.2 per 100,000 in 2012, very close to the average Michigan homicide rate over 2003 to 2016. The U.S. criminal homicide rate for the same year was 4.7. There are differences between “intentional homicide rate” and “criminal homicide rate”. The numbers show the U.S. to be on the low side of the average world rate.
If someone tells you that legal American gun owners are not murderers until they are, tell them that Japanese, without guns, are as likely to murder as legal American gun owners.
Where crimes of people with carry permits are documented, that population has extremely low crime rates. Crime rates as low as the populations of those countries with the lowest crime rates in the world.

One of the nice things about MySQL 8.0 is the ability to combine the relational and document models. As a developer, you can choose to work with traditional SQL tables, with schemaless JSON documents, or with both types at the same time. Here we show how to bridge SQL tables and JSON documents by using JSON functions. Enjoy!
First, let us create a simple SQL Table “employees” and insert some values:
|
|
mysql> CREATE TABLE employees(id INT PRIMARY KEY, name VARCHAR(45), age INT); mysql> INSERT INTO employees(id, name, age) VALUES (1,‘John’, 34); mysql> INSERT INTO employees(id, name, age) VALUES (2,‘Mary’, 40); mysql> INSERT INTO employees(id, name, age) VALUES (3,‘Mike’, 44); |
And then we verify table content:
|
|
mysql> SELECT * FROM employees; +——+——+——+ | id | name | age | +——+——+——+ | 1 | John | 34 | | 2 | Mary | 40 | | 3 | Mike | 44 | +——+——+——+ Query OK, 0 rows affected (0,00 sec) |
Ok, good. Nothing new so far.
From an SQL Table to a JSON Document
Here we use two JSON aggregation functions called JSON_ARRAYAGG() and JSON_OBJECT(). We simply select from employees and convert the result set into JSON like this:
|
|
mysql> SET @jsonempl=(SELECT JSON_ARRAYAGG( –> JSON_OBJECT(“id”, id, “name”, name, “age”, age)) –> FROM employees); Query OK, 0 rows affected (0,00 sec) |
We now have a JSON Document referenced by the variable @jsonempl. Let us look at it using the JSON_PRETTY() function:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
|
mysql>SELECT JSON_PRETTY(@jsonempl); +—————————————————————————————————————————————————————————-+ | JSON_PRETTY(@jsonempl) | +—————————————————————————————————————————————————————————-+ | [ { “id”: 1, “age”: 34, “name”: “John” }, { “id”: 2, “age”: 40, “name”: “Mary” }, { “id”: 3, “age”: 44, “name”: “Mike” } ] | +—————————————————————————————————————————————————————————-+ 1 row in set (0,00 sec) |
Nice!
We then drop the existing “employees” table:
|
|
mysql>DROP TABLE employees; Query OK, 0 rows affected (0,00 sec) |
From a JSON Document to an SQL Table
Here we use the JSON table function called JSON_TABLE(). This function creates an SQL view on the JSON Document, i.e. a mapping between JSON and SQL. We then wrap a CREATE TABLE employees AS around it like this:
|
|
mysql> CREATE TABLE employees AS –> SELECT * FROM JSON_TABLE(@jsonempl, “$[*]” –> COLUMNS (id INT PATH “$.id”, –> name VARCHAR(45) PATH “$.name”, –> age INT PATH “$.age”)) emps; Query OK, 3 rows affected (0,00 sec) Records: 3 Duplicates: 0 Warnings: 0 |
Again, we verify table content:
|
|
mysql> SELECT * FROM employees; +——+——+——+ | id | name | age | +——+——+——+ | 1 | John | 34 | | 2 | Mary | 40 | | 3 | Mike | 44 | +——+——+——+ 3 rows in set (0,00 sec) |
Voilà , we are back where we started !
That’s it for now, and thank you for using MySQL!

MySQL 8.0: From SQL Tables to JSON Documents (and back again)
Wipers should smoothly clear water, snow, and slush from your windshield with no squeaking, chattering, skipping, or grabbing. If you notice these signs, or if a wiper is leaving streaks or bands of water, it may be time for new ones. When long-term testing our picks, they typically worked well for about nine months to a year before showing signs of wear, although this varied, depending on the conditions, the type of wiper, and how well they were maintained. Sure, wipers see a lot of action in wetter and snowier areas, but even in the southwest, where you can go months without rain, they can degrade quickly. The constant heat, dryness, and sunlight can deteriorate the rubber element; we’ve even seen long-unused wipers that had to be peeled off of the windshield glass. So, in those conditions, it’s good to run your wipers about once a week while spraying the windshield with washer fluid.
When we asked representatives from several service shops about problems they’d seen caused by worn, neglected wipers, the answers were both similar and convincing. “I personally have seen people wait so long that the blade becomes old and brittle, and it damages the window,” says Joe Betancourt Jr., VP of Joe’s Expert Auto in Chicago. “In some cases, the blade comes off with the backing and the arm will gouge the glass, causing an expensive and unneeded repair.”
Pete McAdoo, of Honest-1 Auto Care in Portland, agrees, “I’ve seen them come off, come apart to where they scratch the glass. And now they have an etching of the sweep of the wiper on the glass.” McAdoo has also seen disintegrated wipers get hung up on something and damage the wiper motor: over a prolonged period of time, even a wiper that’s chattering and dragging on the windshield “puts stress on the motor and linkage,” which can shorten their service life. “Change them on a regular basis,” he advices. Travis Decker, of Portland’s Atomic Auto Service, agrees: “Wipers are cheap insurance” against more costly repairs.
If you notice your wipers having problems, first try cleaning the rubber blade. Sometimes that’s all it takes to get a few more weeks or months from your existing wipers. Dip a clean paper towel or cloth in a little water, washer fluid, or rubbing alcohol and wipe along the edge of the blade. Also, look at it closely and feel for any adhered debris or roughness. The edge should be sharp and smooth without any nicks, chips, or gaps, and the rubber should be pliable, not cracked or brittle.
In the winter, thoroughly scrape ice off of the windshield before using the wipers, as ice can abrade the rubber and dull or damage the edge.
Geoff Helzer, of Portland’s Green Drop Garage, says that another common problem he’s seen is a film that builds up on the windshield from oily, greasy road-grime spray. “The film can be removed by using a windshield stripper product that does a deep clean of the windshield surface,” he says. It requires some elbow grease, but “has proven to be very effective in returning the glass to a like-new condition.”
If cleaning doesn’t help the wipers, it’s time for new ones. And always replace them in pairs, because if one wears out, the other won’t be far behind.
While a lot of people wait for these problem signs to appear before buying new wipers, it’s better to be proactive and replace them before you need to. Not being able to see clearly in a sudden downpour or heavy snow or ice storm can be a real drag, not to mention dangerous. And then there’s that “cheap insurance” thing, too—it’s better to replace them before they wear to the point where they can cause damage to the car.
So, how often should you replace your wipers? Wiper manufacturers and a couple of the shops we talked to suggest replacing them every six months. But once per year may be a reasonable interval for you. In an online poll we conducted, about a quarter of respondents said they replace their wipers about every nine to 12 months, while about a fifth said every 12 to 18 months. Almost as many—18 percent—agreed that we summed up their thinking on the issue with the question, “Wait. Wiper blades don’t last forever?”
Travis Decker, of Atomic Auto Service, recommends to replace them as needed, but that depends on the climate. “Here, in Oregon, I suggest every fall.” Joe Betancourt, of Joe’s Expert Auto, says, “In areas like where we are (Chicago), I recommend every 3 to 4 months during the winter season, due to icing on the windshield.”
If you have a tough time remembering to get new blades, tie the task to another regular event. The windshield wiper industry has tried to co-opt Groundhog Day as national “replace your wipers day,” so you can use that if it works for you.

The Best Windshield Wipers for Your Car
For years we’ve documented how the internet of broken things industry and evangelists have contributed to a global privacy and security shitshow. The rush to connect everything from tea kettles to Barbie dolls to the internet without including even basic privacy or security standards has resulted in a massive security problem few seem interested in actually fixing. As a result we’re not only less secure and more at risk for privacy violations, but these devices are now routinely contributing to some of the most devastating DDoS attacks history has ever seen.
A year or so ago Bruce Schneier penned what was probably the best explanation of why nothing in the IOT chain of dysfunction seems to improve:
"The market can’t fix this because neither the buyer nor the seller cares. Think of all the CCTV cameras and DVRs used in the attack against Brian Krebs. The owners of those devices don’t care. Their devices were cheap to buy, they still work, and they don’t even know Brian. The sellers of those devices don’t care: they’re now selling newer and better models, and the original buyers only cared about price and features. There is no market solution because the insecurity is what economists call an externality: it’s an effect of the purchasing decision that affects other people. Think of it kind of like invisible pollution."
Instead of fixing their products, vendors simply move on to marketing the next best thing. And consumers continue to gobble them up, creating millions of millions of new attack vectors into homes and businesses around the world annually. Obviously this "invisible pollution" continues to have a very real and visible impact. Case in point: Nicole Eagan, the CEO of cybersecurity firm Darktrace, says hackers are increasingly targeting unprotected IOT devices including air conditioners, toys, and surveillance cameras to get into corporate networks.
She noted how one bank that decided to skimp on security cameras actually wound up being hacked after those cameras were quickly compromised by attackers. Speaking at the WSJ CEO Council Conference, she also shared an anecdote about how one big casino client had their customers’ financial histories stolen thanks to an internet-of-broken things aquarium thermostat:
"Eagan gave one memorable anecdote about a case Darktrace worked on in which a casino was hacked via a thermometer in an aquarium in the lobby. The attackers used that to get a foothold in the network," she said. "They then found the high-roller database and then pulled that back across the network, out the thermostat, and up to the cloud."
It’s understandable that people are wary of regulating this sector lest it stifle innovation or create unforeseen, additional problems. But it’s pretty clear we’re going to need a massive collaboration between the public, companies, and government if we want to avoid some potentially calamitous and fatal outcomes (especially if and when essential infrastructure is targeted). That’s why what the open source IOT security and privacy standards organizations like Consumer Reports have been cooking up desperately need all the public and private sector support they can get.

A Casino Was Hacked Thanks To The Internet Of Broken Things & A Fish Tank Thermometer
Gun writer Tom Mchale lets us in on his five must-own shooting accessories.
USA –-(Ammoland.com)- There’s always something new and cool on the gun gear shooting accessories market. People like you and I often get excited about something or another because it seems like such a good idea, or so handy, or maybe it’s such a great deal. Like most other product categories, shooting gear must pass the test of time for it to make the true favorites list. Once the shiny new novelty wears off, do you still find the same value from that piece of gear? Here are a few shooting accessories that have survived many of my ruthless range bag reorganizations.
We all put in an hour or so per day of dry-fire practice, right? What? You don’t? Well, disregarding the fact that we have plenty of other things to accomplish and that dry-fire practice has been known to induce boredom comas, some slippage in the daily schedule is understandable.
Here’s one shooting accessories that’s made practice either at home or the range much, much more interesting and effective. The MantisX Shooting Performance System consists of a small, light, and rechargeable device that you mount to the rail of your pistol and a smartphone app. As you might guess, these two things communicate. Oh, if your gun doesn’t have a rail, check the MantisX.com website – they offer adapters.
Anyway, the MantisX has magic sensors that detect the slightest movement prior to, during, and immediately after the trigger press. This data is sent to the smartphone app so you can see what you’re doing graphically. The app also assigns numerical scores to each shot based on the amount of movement through your shot. The company has been continuously updating the app so it now includes structured drill and training routines you can use to measure progress against skills over time. You can also set up accountability groups with friends to share results.
Here’s what makes the MantisX extra super nifty. Not only can you hone your skills dry-firing at home, but you can also stick this on a CO2 pellet or BB pistol to simulate some noise and recoil. Lose the pellets, and you can shoot blasts of air inside your house, at least when your spouse is out running errands. Better yet, take it to the real range and run it with live ammo. It’ll tell you exactly why you’re hitting or missing.
As shooting accessories go, I’ve been using the UM Tactical Pistol Optics Mount for a couple of years now, so it’s proven its utility over the long haul. Here’s what it does.
The device hooks to the rail under the muzzle and wraps around both sides of the frame and slide, without touching, meeting again maybe a half-inch over the slide. At the top, the two halves join to form a Picatinny rail segment on which you can mount a red dot sight or magnified handgun scope. Since nothing touches the slide, your pistol functions through recoil normally and the rail and mounted sight don’t move at all.
Being able to mount a red dot sight on a pistol not originally designed for one is cool and plenty of fun. Mounting a magnified handgun scope on your favorite pistol opens up all sorts of possibilities. If you’ve got an accurate gun, it’s no big thing to hit targets 100 yards or farther with ease. I use it for precise accuracy testing at 25 yards because the scope completely removes the issue of shooting sighting error. It also makes an interesting solution for long-range plinking or hunting provided you have the right caliber/game match.
Sometimes the simplest shooting accessories are the handiest. That also can (rarely as in this case) apply to the least expensive things. While I’m sure, you can find magazine pouches for a few pennies less (the MSRP of these guys is $26.00) it’ll be hard to match the durability and usefulness.
The Blue Force Gear Double Pistol Belt Pouches define “zero bulk” as the front and back surfaces add mere millimeters (if that) to the thickness of your magazines. The back is a cloth laminate called ULTRAcomp that’s flexible but super tough. The front is made from military-grade elastic. That means that the pouches stretch to accommodate magazines of any size: single, stack, double-stack, and caliber of your choice. This elastic does spring back to original size so you can stick fat double-stack magazines in one day and singles the next. The belt loops are constructed from hook and loop material. That’s tacti-speak for Velco. You can size the dual belt loops to any belt width up to two inches.
The versatility is great, but one reason the Blue Force Gear Double Pistol Belt Pouches make the favorite five shooting accessories list because they’re soft and flexible – great for concealed carry. Also, there’s nothing that says you have to carry two magazines. If you like, you can carry one and some other piece of gear. I often stick a multi-tool or flashlight in the second pouch.
I live in Sub Sauna Carolina. It’s hot for at least 592 days per year. It’s not only hot but steamy humid. So, all the great advancements in low-cost electronic hearing muffs still end up as a sweaty mess on my head. Those also tend to press safety glasses frames into your temples, making a permanent moat between your eyes and ears. Sure, you can use foam ear plugs, and they work great provided you don’t want to hear anything at all. Or, you can drop a couple of grand on custom-molded in-ear electronic plugs. Or…
You can invest about $300 in a set of Etymotic GunSport Pro electronic plugs. That’s not pocket change, and if you are a once-per-year shooter, they’re probably not for you. However, if you frequent the range or compete, they pay for themselves really quickly in comfort and convenience. The kit includes six different sets of ear tips so you can achieve a perfect fit that won’t give you an earache. When I go to events and training classes, I’ll just leave them in all day long – they’re that comfortable.
The Etymotic GunSport Pro Electronic Ear Plugs dampen gunshot noise to hearing-safe levels. An alternate setting magnifies nearby sounds by 5x while still providing protection again dangerous noise levels. That’s handy for hunting or hearing range commands clearly. I’ve tried lots of others, and these take the cake for their excellent and very natural sound quality. That combined with all-day comfort lets you forget you’re wearing them. One more thing. Unlike large over-the-ear muffs, these don’t get in the way when shooting rifles and shotguns.
I don’t know about you, but I thoroughly clean my guns immediately after range outings – or at least as often as every 10 or 57 times I go shooting. I used to be a shoot once, clean once kind of guy, but I figured out, concurrent with the onset of male pattern laziness, that modern guns work pretty darn well and don’t really need to be cleaned every couple of dozen shots. Not to mention all that taking apart and cleaning multiplies the odds that you won’t put something back in place just right. Unless you clean your guns at the range after your done shooting and can fire a couple of test shots, you don’t really know for double-secret-sure that your gun is in proper functioning order.
My less than rigorous training routine is one of the reasons I always carry a bottle of gun Hoppe’s Gun Medic Cleaner and Lube Quick Fix in my shooting bag. The combo cleaner and lube comes in an aerosol can. The cleaner blasts the nasty stuff away and then evaporates, leaving a thin layer of lube behind. To be clear, this combo packaging is for exactly what the name says – a quick fix. The idea is to get your gun working when it’s sluggish from filth without having to field strip and start cleaning. Just spray in the action or through the ejection port. It works like a champ on semi-automatic pistols and AR-type rifles. If you like the lube, you can buy the cleaner and lube separately for proper apres-range cleaning.
So, my favorite five shooting accessories? Yes, if I weigh the choices based on what I’ve actually ended up using consistently over the long haul.

Shooting Accessories , My Favorite Five Must-Haves
Apple hardware is often cited for reliability, but you can end up with an expensive fix when something goes wrong. That’s why it’s great if you’re able to perform your own hardware tests before approaching an Apple professional about a potential fix.
Thankfully, testing your Mac at home is free, simple, and takes only a matter of minutes.
Which version of Apple’s hardware test you’ll use depends on the age of your Mac. Computers released before June 2013 will use Apple Hardware Test. Computers released after June 2013 will use Apple Diagnostics instead.
The older Apple Hardware Test (AHT) doesn’t provide as much information about your system as Apple Diagnostics. It runs cursory tests on components and determines whether they are present and operable. The results are fairly easy to interpret, but not particularly detailed.
Apple Diagnostics provides more information about your Mac’s hardware than AHT. At the end of the test, you’ll get an error code which you can use to help decide which hardware components are having an issue and what to do about it.
Neither of these tests are as conclusive as Apple Service Diagnostics (ASD), which is Apple’s own in-house testing. If you take your Mac to an Apple Store for a Genius Bar appointment, they’ll hook up an Ethernet cable and run ASD to get far more detailed results about the status of your machine.
My iMac is having some serious issues with the HD. Found Apple Service Diagnostics to run on it. I have a feeling that I’ll need to buy a new HD.
— David Rogers (@davidjrogers) April 9, 2018
While there’s no official support for ASD beyond that provided to Apple’s technicians, you can download 25GB of diagnostics discs from the internet Archive.
Regardless of which diagnostic tool you’re using, the method for testing your Mac is the same:
If you’re using the older Apple Hardware Test there’s one more step: press the T key to begin the testing procedure. You can also check Perform extended testing to run a more thorough and time-consuming diagnostic. If you’re using Apple Diagnostics, you only need to specify your language.
You will see your results onscreen once the scan is complete. Make a note of any reference codes you receive, since you’ll use those to interpret your results in the next section.
It’s possible your older Mac doesn’t include the diagnostic tool on its disk. If your disk or startup partition is damaged, this may cause the diagnostic test to not run at all. In this instance you’ll need to run the diagnostic via the internet.
It’s easy to do, but it will take longer since you’ll need to download the relevant tool before you can begin the procedure. In order to run a diagnostic test from the internet, follow the same procedure outlined in the section above but hold the Option + D keys instead of just D.
You’ll need access to the internet via a wired or wireless connection for this to work.
Apple Hardware Test should provide some fairly easy-to-understand diagnoses, including reference codes. I tested an old MacBook Air that has no battery in it, and the AHT report and reference code matched up.
If you’re using Apple Diagnostics, you’ll have a greater array of codes at your disposal. You can cross-reference them using the Apple Support reference codes list. Some notable reference codes include:
While these codes only provide a limited amount of information, it might be enough to point you in the right direction. If you’re getting battery errors, it’s probably time to replace your battery. You might even be able to save a few bucks by fixing it yourself

.
Others codes might raise more questions than answers. If you’re getting memory errors, it’s probably worth following up with a more in-depth testing tool. We recommend a free tool called memtest86, which you can run from USB for a detailed scan.
Other problems are tricker to resolve. If you’re getting errors about your Wi-Fi or Bluetooth hardware, it might be worth spending a small amount of money on a USB adapter that offers a workaround for dodgy internal hardware.
Problems with your main processor or graphics processor are harder to isolate and resolve. Further, you might find that your computer passes Apple’s tests but still has issues. At this stage, it’s probably worth talking to a professional or considering a replacement model

USA – -(Ammoland.com)- On Friday, April 6, 2018, U.S. District Judge William Young said assault weapons are military firearms and aren’t protected by the constitutional right to “bear arms.” However, he couldn’t be more wrong.
First and foremost, the term “Assault-Weapon” is a made up term by the gun control lobby to strike fear into the hearts and minds of Americans. Gun control activists rely very heavily on fear-based language to pursued Americans that guns are naturally evil, and that the only solution is to pass stricter gun control laws.
Assault is an action; it’s a verb, not a noun. Firearms have no soul, they’re not living objects, and they are not inherently evil. You could put a loaded firearm on a table, leave it there, and unless somebody picks it up, aims it, and pulls the trigger; the firearm will remain harmless. Which settles the debate of “guns don’t kill people, people kill people.”
The origin of this term “Assault-Weapon” is not one hundred percent clear. According to the Nexis News database, the first mention of “assault weapons” appears in a 1980 New York Times story. Over the past several decades, gun-control proponents have heavily relied on this terminology and have blanket-applied it to any firearm that looks scary.
Secondly, gun-control proponents now slap on the term “assault” to any firearm they don’t like or want to be restricted from public use. The public mistakes the “AR” in AR-15 to mean “assault rifle,” while fake news headquarters CNN, frequently refers to AR-15’s as “assault rifles.” The “AR” in “AR-15” stands for “ArmaLite,” the company that first manufactured the AR-15 in December 1959.
Thirdly, addressing the issue of the “AR-15” and how dangerous it is. These semi-automatic rifles, not “fully automatic machine guns” as some gun control puppets, like Whoopi Goldberg, would have you think. Semi auto firearms have been in public circulation for more than 60 years. It wasn’t until almost 50 years later that we saw one used in a mass shooting.
Nikolas Cruz – Parkland massacre. Police visited Cruz’s home more than 30 times since 2011. Even worse, the FBI had received to tips about Cruz before he committed his horrible act. The first on September 24, 2017, when Cruz posted the comment “I’m going to be a professional school shooter” on a YouTube video, and the second on January 5, 2018, when an anonymous person called the FBI to warn them about Cruz. The FBI admitted to not following established follow up protocols. “Under established protocols, the information provided by the caller should have been assessed as a potential threat to life,” the FBI said.
Devin Patrick Kelley – Sutherland, Texas Church massacre. Kelley should not have had access to firearms, according to Texas Governor Abbott and current federal law. Kelley was dishonorably discharged from the military, which automatically bars someone from ever purchasing firearms again.
Omar Mateen – Pulse Nightclub massacre. Mateen had been on the FBI’s suspected terrorist list, investigated twice by the FBI for terrorism, and convicted of misdemeanor hate crimes.Syed Rizwan Farook and Tashfeen Malik – San Bernardino massacre. According to then FBI Director James Comey, both were “radicalized” before they started dating each other and that they were “homegrown violent extremists” who were “inspired by foreign terrorist organizations.” Farook and Malik did not purchase their firearms. The firearms used in the massacre were a “straw purchase” bought by Enrique Marquez Jr., who pleaded guilty in February 2017.
Fourthly and finally, an “assault weapons” ban certainly violates the Second Amendment. In 2008, Justice Scalia handed down one of the most historic, landmark decisions in the history of the United States Supreme Court. DC v. Heller held that “the Second Amendment protects an individual right to possess a firearm unconnected with service in a militia.”
In the majority’s opinion written by Justice Scalia, he states that the second amendment protects firearms that are in “common use.” The National Rifle Association estimates that there are more than eight million AR-15’s and its variations in circulation. The AR-15 has been in circulation and readily available for purchase by law-abiding citizens since 1959. And if you’re still not sold on the fact that AR-15’s, and its variations, are in “common use” you can read these self-defense stories from 2013 – 2018, in which an AR-15 saved lives and stopped crime.
