Suggested January 2024 Everything You Need To Know About Apple’s New M1 Ultra Chip
If you watched Apple’s “Peek Performance” special event this week, then there’s no question you witnessed the unveiling of the company’s brand new M1 Ultra chip.
Apple wasted no time touting the new M1 Ultra chip as an engineering marvel, and since it unseats the M1 Max as Apple’s most powerful in-house designed chip, we’re sure that many of you have a lot of questions about it. So in this post, we’ll try to spell it all out for you.The M1 Ultra chip – What is it?
The M1 Ultra chip is effectively described as two M1 Max chips that are tightly woven into a single package.
While the industry has seen dual processors in computers before, such as with dual-Intel Xenon workstations, the M1 Ultra works a bit differently in that the two chips aren’t linked by the motherboard, but rather within the actual chip package itself. This key detail means that the M1 Ultra enjoys lower latency, lower power consumption, and improved bandwidth.
As for the numbers, Apple claims that the Ultra Fusion architecture that bridges the two M1 Max chips to form the M1 Ultra chip allows for twice the connection density of anything comparable in the industry today by connecting over 10,000 signals with a mind-blowing 2.5TB/s of interprocessor bandwidth between the chips. Apple says this is more than 4x the bandwidth of the leading multi-chip interconnect technology.What are the specs of the M1 Ultra?
All the details discussed above are remarkable, but by now, you’re probably wondering what Apple is packing underneath the hood of this beast. Your curiosity is warranted.
Since the M1 Ultra is effectively two M1 Max chips linked together, you can take the specs of a M1 Max and multiply them by a factor of two. M1 Ultra maintains the same 5nm process as the M1 Max, but everything else is doubled. This gives you 114 billion transistors, 20 CPU cores, 32 GPU cores, 32 Neural Engine cores, 800GB/s of memory bandwidth, and support for up to 128GB of unified memory.
The CPU cores are further broken down into 16 high-performance cores and four low-power cores. The high-performance cores are optimized for more demanding tasks that include audio & video editing, compiling code, and 3D gaming, among other things. The low-power cores are ideal for conserving the most power as your machine performs background tasks while it sleeps or performs less intensive user-performed tasks.How does the M1 Ultra perform?
Since the M1 Ultra chip has yet to be released into circulation, we have yet to witness any real-world tests or comparisons. Current information is based entirely on Apple’s marketing and stray synthetic benchmark tests that have appeared online. We can tell you what we know so far…
With an industry-leading performance per watt, Apple says that the M1 Ultra chip can deliver multi-threaded CPU performance comparable to that of the latest Intel Core PC desktop chip while using 65% less power in doing so. Compared to the fastest 16-core PC desktop chip currently available, Apple says M1 Ultra delivers 90% more performance while using 100W less power.
Apple also shares bold claims for the M1 Ultra’s GPU, which is said to be capable of delivering similar performance to an unnamed yet allegedly “popular” discrete PC GPU while using 1/3 of the power. Additionally, Apple says it will deliver faster performance than the highest-end PC GPU available, all while consuming 200W less power.
Impressive, right? It seems so, but we always recommend waiting for real-world tests to emerge before taking Apple’s word for it.Which Macs offer the M1 Ultra chip?
The $3,999 price tag gets you the M1 Ultra chip with 20 CPU cores and 48 GPU cores. Unlocking the additional 16 GPU cores to get you to 64 GPU cores in total will cost an additional $1,000, while boosting the unified memory (RAM) up from 64GB to 128GB will cost an additional $800, bringing the total cost of a fully unleashed M1 Ultra chip in a Mac Studio up to $4,799, excluding the cost of storage upgrades.
It’s possible that the M1 Ultra could become an option in additional Mac offerings in the future, but it certainly seems like a major selling point for Apple’s latest modular Mac desktop computer, so it’s a tough call.
One thing worth noting is that the Mac Studio features a beefy cooling system, so it seems unlikely that M1 Ultra will make its way to any of Apple’s notebook computers like the MacBook Pro. These machines are simply too thin to house comparable cooling capacities.Do you need the M1 Ultra chip?
When Apple came out with the MacBook Pro refresh at the end of last year, they introduced the M1 Pro and M1 Max chips alongside the standard M1 chip.
The consensus among reviewers and tech junkies was that most users could squeak by with an M1 chip. If you did even a little bit of heavy computing, then you could absolutely get by with just the M1 Pro chip. The M1 Max was something of a novelty for the elite top 1% of users who demand uncompromising speed and efficiency in their workflows.
We think that the M1 Ultra chip is much like the latter, being mostly useful for professionals who need the power to do their best work in as little time as possible without the jitter of bandwidth constraints on slower chips. This is hardly a necessity for anyone else.
The M1 Ultra chip isn’t designed, nor is it priced, for the average Joe. You would be wasting your money if you bought a machine equipped with this chip just to scroll through Twitter feeds and watch YouTube videos, however it’s your money, so do you.Wrapping up
While we’ve attempted to round up all the most important information about Apple’s brand-new M1 Ultra chip, we expect that there are probably many other questions.

Video comes in all sorts of aspect ratios, such as 16:9 widescreen and 21:9 ultra widescreen. These are pretty immersive, but what about a video that spans a whole 360-degree around you?
Yes, it’s possible to make spherical video that really puts the viewer right in the middle of the action, but obviously the equipment that we use to make more traditional video isn’t the right solution. So if you’re interested in either making or consuming 360-degree video, here’s everything that you need to know.
Table of Contents360-Degree Video Is Not (Exactly) VR
However, since 360-degree videos are not interactive or computer-generated, there is some debate as to what extent we can really lump them in with VR. So while the convention might be to refer to this media format as VR video, it’s good to know that a clear distinction exists.Why Choose 360-Degree Video?
Every aspect ratio or format of video has its own unique attributes that make it suitable for one purpose or another. As has been said many times before, the medium is the message.
This type of video is perfect when you want to convey what it feels like to stand in a particular place. Unlike traditional video, the viewer in a 360-degree video gets to choose what deserves attention. You can’t direct their viewpoint through framing as with traditional video formats.
That means it’s best to use this video format for content that doesn’t rely on precise framing and benefit most from immersion. Training videos are one good example, as are concerts and theatre performances. Action sports videos have also become a popular medium and tours of places like museums or other travel locations are also perfect for 360-degree video.
That doesn’t mean you can’t use this immersive video to tell a story, but it needs a new visual vocabulary to properly guide the story, something they didn’t teach in film school in the past for obvious reasons.Camera Types
As you can imagine, a normal camera isn’t going to produce this sort of surround video. You need a special setup in order to capture spherical video. There is no standard for this though. Some rigs are literally several regular cameras stuck together. Then special software is used to stitch the various overlapping camera feeds into one 360-degree video.
There are now also specialized 360- and 180- degree cameras that use fish-eye lenses to bend the incoming image onto a standard sensor. Software then undoes the known distortion of the lens to provide a clear image, but one that give you a surround view of what was filmed.
In general, the fewer cameras needed to create the final image, the more seamless it will look. Using makeshift multi-camera rigs makes it much more likely that there will be stitching errors. Which show up as visible cuts in the final image, where things don’t quite line up.
For the regular person on the street, something like the Insta360 line of smartphone-attached cameras is a good place to start.Computer-Generated 360-Degree Video
Using cameras isn’t the only way to generate 360-degree video. You’ll find plenty of examples that are made using 3D animation software or from video games using a custom field of view that encompasses 180- or 360- degrees.
Obviously it’s pretty simple to create stereoscopic video this way as well, since you have full control over the rendered world. It’s also a good way to bring non-interactive CG experiences to hardware platforms that have no hope of running them natively on local hardware.Monoscopic & Stereoscopic Video
Another major subdivision within 360-degree video formats is between monoscopic and stereoscopic video. Basically, monoscopic footage isn’t in 3D. Although you have a giant video that surrounds you as a viewer, it’s still flat. Stereoscopic 360-degree video gives each eye it’s own unique feed, which your brain interprets as a 3D image.
Obviously 3D video is more compelling, but it’s much more complex when it comes to equipment. Basically, you need two independent 360-degree cameras, mounted at precisely the right distance from each other. Cameras that can shoot stereoscopic video like this are quite a bit more expensive, so most of the video you’ll find is the non-3D kind right now.Editing 360-Degree Video
Fundamentally, 360-degree video is no different than any other digital video file. So, in principle, you can edit it with any software that can read the video codec used to encode it. However, the video is going to look like a distorted mess, shown as a normal frame.
Software designed to edit or play this type of video warps the footage into the correct spherical form, so that everything looks the way it should. Which means it’s best if you use an editing suite that knows how to do this.
More often than not, your camera will come bundled with some sort of editor. What specific features are present will depend on the app in question.
Professional editing packages such as Adobe Premiere and Final Cut Pro natively support editing 180-degree and 360-degree video, as do other mainline video editing solutions. If you already have one of these programs, you may find you can also already work with this format.Supported Platforms
So, once you have recorded and edited your 360-degree masterpiece, where can you actually upload it for other people to watch? Believe it or not, YouTube already supports several formats of 360-degree video.
There are also several apps for mobile devices that also support 360-degree video, but of course the user has to download the video to their device and can’t stream it.Watching 360-Degree Video
The other way is to simply watch the video on a normal screen. On desktops, you can look around by using the mouse and on mobile phones you can swipe with a finger or use the phone’s built-in motion sensors.Our Favorite Examples Of 360-Degree Video
Now that you know the most important information about this exciting video format, the only thing left to do is highlight some excellent examples of video you can try out for yourself right now.
Starting off with an example of live music performances, check out Childish Gambino’s “Me and Your Mama”. The camera I set low to simulate being at the show, but other videos even put the camera on stage so you can stand with the musicians and see the massive crowds.
This promotional video for the new Doctor Who series is both an example of a CG video and a narrative video. You don’t even have to be a fan of the show to appreciate how cool this concept is.
Everything You Need to Know about Forecasting Headcount Spend
Why and how to correctly forecast spend on headcount
Published April 6, 2023
Updated April 14, 2023How to Forecast Headcount Spend
Your headcount spend is one of the most important numbers to project correctly.
Most people don’t realize that their headcount typically accounts for 50-80% of their cash burn. But it makes sense — a company’s biggest asset is its people, so it shouldn’t come as a surprise that it may be the biggest expense as well.
That’s why it’s crucial to understand your headcount forecast. Even the slightest mistake can make a huge impact on planning.
When you project your headcount spend correctly:
You get insights into who you can hire and when
You understand where your cash is going
You get ahead of any surprises
When done incorrectly:
Your cash-out date hits sooner than expected
You may be forced to do layoffs, with exit packages and other unexpected costs
Company morale takes a hit as others fear for their job security
Let’s get into the why, how, and what of forecasting headcount the correct way.Why Should You Forecast Your Headcount Spend?
Your headcount spend will often account for 50 to 80% of your cash burn each month. Within this, the salary costs are the main driver of structure costs.
A good forecast can help determine the break-even point for the company to cover the structure costs. It provides the sales volume needed to reach profitability.
Your headcount spend can also be one of the most challenging costs to reduce, with a number of challenges ensuing from lay-offs — including severance, lawsuits, and decreased work morale.
Forecasting your headcount expense will allow you to make better informed decisions as you plan for your cash burn for the next 12-18 months.How Do You Forecast Your Headcount Spend?
To begin, you need to define your needs for the next 12 to 24 months depending on your backlog and sales projections.
Next, begin adding your projected hires one by one.
For a long-range forecast (12 months or more into the future), add roles in bulk.
Consolidate and review the consistency of all headcount with the management team.How Do You Calculate Projected Spend?
Now that you have your inputs, it’s time to calculate your projected spend for each month. There are two ways to go about doing this:The simple method
Determine the departments with direct FTE.
Apply the business growth ratio to the direct FTE to calculate the traditional headcount.
Use one salary increase rate across the board to calculate the salary costs for next year.
Your salary costs for next year should be (# of FTE next year X average salary per FTE current year X (1+salary increase).The detailed method
Prorate the salary for any hires who joined this month, or were terminated.
Full-time employees have a number of other incidental costs:
Employer payroll taxes which are around 8 to 10% of salary
Health benefits which are around 8 to 10% of salary, or a fixed dollar amount per employee
Payroll processing fees which is around 2.5% of salary, or a fixed dollar amount per employee
Other payroll costs to consider
Commissions (could be monthly, quarterly, or annually)
Recruiting fees (often a percentage of first year salary)
Additional structure costs that include place, energy, and equipment — these could be marginal if the structure is already big, but for a smaller team, this is an impact to considerPutting It All Together
Once you have all the information entered, you can start to use it to analyze your headcount:
Slice and dice your data on a department basis, and by each cost type
Use graphs to understand costs and hires by department and across multiple periods
Use ratios like FTE increase VS sales increase
Being in full control of your headcount planning allows you to analyze the data in a variety of ways. This includes:
Headcount: The evolution per month and compared to your budget.
Percentage of direct employees: A direct employee works directly on a project or production order, whereas an indirect employee has more of a supervisory or a support function role — figure out what employees are working directly on projects and which are supporting.
Flexibility: You gain flexibility through contractors or temporary workers, and understanding this will help you know how much you can reduce or increase your activity to adapt to the business demand.
Capacity: Compare the gross capacity (hours before holidays, sickness, leaves) as well as the net capacity to help explain why there are less or more hours worked.
Turnover rate: The number of employees leaving the company compared to the total number of employees. You can see if there is some anomaly in some departments or some reason for the turnover.
The key is to not just create the headcount forecast and stop there. You want to provide ongoing reporting to ensure that the company continues to stay aligned on its plan, and its progress against that plan.
The Galaxy S22 series will be replaced by the Galaxy S23 and its Plus and Ultra variants. We are still eagerly awaiting these newcomers to the most well-liked premium range of the Android ecosystem. Will we be entitled to a modest evolution or to significant changes and innovation? In this detailed Galaxy S23 article, you can find the answer to this question.Galaxy S23 release date
When it comes to the release of smartphones for its main series, Samsung adheres to a very strict schedule. The South Korean manufacturer habitually releases its Galaxy S in February. Because it no longer exhibits at the MWC in Barcelona, where it previously unveiled its new models at the end of February for marketing in March. Recall that on February 9 at the Unpacked conference, the Galaxy S22, S22+, and S22 Ultra were unveiled before going on sale on February 25.
Samsung, however, has a good chance of releasing the Galaxy S23 earlier than expected. The three new models could very well be released early in 2023, in January. This would be consistent with Qualcomm’s announcements that its upcoming Snapdragon Summit conference will take place in mid-November rather than early December. Samsung will probably have access to chips earlier than in previous years, just like other manufacturers.
A poster from the Korean carrier KT states that the smartphones will be unveiled starting on December 23 (or even the day before). With general availability in stores beginning on January 6, 2023. It will be interesting to see if this leak is verified.Galaxy S23’s prices
8GB + 128GB: $799/£769/€879
8GB + 256GB: $849/£819/€929
8GB + 128GB: $999/£949/€1,079
8GB + 256GB: $1,049/£999/€1,129
Galaxy S22 Ultra:
8GB + 128GB: $1,199/£1,149/€1,279
12GB + 256GB: $1,299/£1,249/€1,379
12GB + 512GB: $1,399/£1,329/€1,489
12-GB + 1TB: $1,599/£1,499/€1,689Galaxy S23 design
Samsung is being fairly conservative with the design of its Galaxy S range of smartphones, similar to how Apple is with its iPhones. The Galaxy S22 Ultra, which replaced the Galaxy Note by including a slot for the S Pen stylus and adopting a less curved and more square design, was the most recent significant change. The Galaxy S23 Ultra will likely have an even more angular chassis than the S22 Ultra, according to the insider Ice Universe. The screen’s curved effect will also be less obvious.
The Galaxy S23 series’ design will be very similar to what we already know for the most part. The punch will be back because there won’t be an under-screen selfie camera like on the Galaxy Z Fold 4. This generation confirms that the cameras are frequently the components that change the most between the two. The three cameras on the Galaxy S23 and S23+ protrude from the back cover of the smartphone, forming three distinct islands as a result.
There will also be a small difference in the dimensions. According to OnLeaks, the Galaxy S23 will be 146.3 x 70.8 x 7.6 mm in size as opposed to the Galaxy S22’s 146.0 x 70.6 x 7.6 mm dimensions. Samsung will enlarge its smartphone slightly while keeping the thickness the same. As a result, and against all expectations, the screen’s borders will widen. The Galaxy S23 + should have dimensions of 157.7 x 76.1 x 7.6 mm compared to the Galaxy S22 +’s 157.4 x 75.8 x 7.64 mm. The smartphone is consequently 0.3 mm longer than its smaller variant, but it is also 0.3 mm wider. Therefore, the borders could become 0.15 mm thicker on each side.
Unsurprisingly, the three smartphones will have IP68 certification, making them dust and water-resistant.Galaxy S23 screens
For the S23 series, Samsung uses its top-level Super AMOLED display technologies. Thus, as has been the case since the Galaxy S21, Dynamic AMOLED 2X screens are HDR10 + compatible and provide a refresh rate of up to 120 Hz on all models. The Galaxy S23 Ultra’s screen has a resolution of 3088 x 1440 pixels (Quad HD +). While the Galaxy S23 and S23 Plus’s screens have 2340 x 1080 pixels (Full HD +). It is also classic in terms of sizes:
Galaxy S23: 6.1 inches
Galaxy S23+: 6.6 inches
Galaxy-S23 Ultra: 6.8 inches
The Galaxy S23 Ultra should once again be the only model with an LTPO 2.0 display, which will enable it to dynamically vary its refresh rate from 1 to 120 Hz in order to adapt to the content displayed and thereby save some battery.
Samsung should install Qualcomm’s 3D Sonic Max, which is already found on the Vivo X80 Pro, under the screen of the S23 Ultra. This sensor can even register a fingerprint with a single tap and is faster and wider than other sensors. Additionally, it supports a security mode that uses two fingerprints at once.Gizchina News of the week

It has been discussed for years that Samsung might stop using its Exynos chips in its high-end smartphones in Europe, and now it may actually happen. Exynos SoCs will not be offered by Samsung in 2023 or 2024. The manufacturer wants to take its time developing a new, high-performance chip for the market in 2025, as the Exynos has always struggled to compete with Qualcomm’s Snapdragon. The ultimate objective would be to compete with Apple, the industry leader and great champion.
The South Korean company and Qualcomm have agreed to a multi-year strategic partnership for the delivery of chips. In order to prevent heating and preserve the battery, the S23 series will therefore ship with a Snapdragon 8 Gen 2 SoC, which has been declared to be more effective than the Snapdragon 8 Gen 1 SoC, especially at the GPU level. The CFO at Qualcomm, Akash Palkhiwala, has also confirmed this.
This year, Qualcomm would choose a 1+2+2+3 core configuration, with a Cortex-X3 Prime core running at 3.36 GHz, two Cortex-A715 cores, two Cortex-A710 cores, and three Cortex-A510 cores, all running at 2.0 GHz. This information has also been verified by the Galaxy S23’s initial Geekbench benchmark. The Galaxy S23 scored 1524 points on a single core and 4597 points when using multiple cores.
In terms of connectivity, all Galaxy S23s are obviously 5G and Wi-Fi 6E compatible, but we might also be entitled to the new Wi-Fi 7 standard. The Galaxy S23 and S23 Plus have 8 GB of RAM, while the Galaxy S23 Ultra has 8 or 12 GB. The Galaxy S22 and S22+ also have a choice of 128 or 256 GB of internal storage. As opposed to 256, 512 GB, or 1 TB for the S23 Ultra.Galaxy S23 battery life
We regretted the Galaxy S22’s somewhat limited autonomy. With the Galaxy S23, Samsung should make it right. The smartphones in the series are all a little bit bigger than the previous models, as was already mentioned. The brand should be able to increase the size of the battery built into two of its products by about 5% as a result of the space savings. The Galaxy S23’s battery would be about 3900 mAh in comparison to the Galaxy S22’s 3700 mAh. In addition, the Galaxy S23+’s battery would have a 4700 mAh capacity in comparison to the Galaxy S22 +’s 4500 mAh.Galaxy S23 camera
Every year, the Galaxy S Ultra model is among the best smartphones available. And the Galaxy S23 Ultra should be no different. The 108 MP sensor that has been on the Ultra since the Galaxy S20 will be replaced with a new 200 MP photo module by Samsung this year, which is an innovation. But it shouldn’t be the well-known Samsung ISOCELL HP1, which we’ve seen in action on Xiaomi and Motorola smartphones. Instead, Samsung would create the ISOCELL HP2, an HP1 variant. With a smaller (1/1.3 inch) but still quite an effective sensor.
Due to a more sophisticated pixel fusion technique, these 200 megapixels will not only enable you to take ultra-high-definition pictures but also produce images with more light. In fact, because this sensor has such a large number of pixels. It is now possible to combine many of them to create larger, brighter pixels while still maintaining a high resolution.
Due to its highly developed night mode, some are already quick to proclaim that the Galaxy S32 Ultra will be the best smartphone for photography in 2023. The Galaxy S23 Ultra should retain the S22 Ultra’s optics, which include a 10 MP ultra-wide-angle lens, a 10 MP telephoto lens with optical image stabilization and optical zoom up to 3x, and a 10 MP periscopic lens with 10x optical zoom.
Although it is unknown at this time whether a hardware upgrade is intended. The Galaxy S23 and S23 Plus would maintain a shared technical sheet with regard to the camera. A 50 MP ISOCELL GN5 main sensor, a 12 MP ultra wide-angle. And a 10 MP telephoto lens with a 3X optical zoom will be present if nothing changes.
Since the Ultra model first debuted in the lineup, the front camera for selfies has always benefited from a 40 MP module. And that should continue to be the case. In recent years, the 10 MP lens on the Galaxy S22 and S22 Plus could be replaced with a 12 MP lens.Galaxy S23 software
The Galaxy S23 series of smartphones will all debut with One UI 5, Samsung’s custom interface built on Android 13. The most recent version of the mobile operating system. In this version, the interface’s design is changed. The notification panel has been redesigned, and there are also new alert icons, slightly adjusted opacity for quick settings. And a change in the location of the box dialogue managing the user’s authorizations.
The company has also improved the system’s animations and added new multitasking gestures. Optical character recognition, which recognizes text from images for simple copying and pasting, is one of the new features. The assessment of the WiFi connection’s quality for OneUI 5.0’s Internet connection is another innovation. It enables you to access a wealth of data on the performance of your home network, identify dead spots throughout your property, and guide the proper installation of Wi-Fi repeaters.
Microsoft earlier bought Windows operating system to ARM-based devices with Windows RT for x32 ARM Processors. Windows RT was first announced at CES 2011 and was released as a mobile operating system along with Windows 8 in October 2012. It was designed to come preinstalled with hardware from specific OEMs. Microsoft’s first Surface Tablet had an ARM-based processor made by NVIDIA, and it ran Windows RT as well. There were many other devices from other Microsoft partner OEMs like Dell and HP that were shipped with Windows RT and an ARM Processor. But now Microsoft is returning to the game with Windows 10 on ARM.What was Windows RT
Windows RT was another flavor of Windows 8 released along with it designed specifically for low powered devices. As mentioned above, these low powered devices came with ARM processors like the Qualcomm’s Snapdragon 800 or ARM chipsets made by makers like NVIDIA (Surface).
This gradually decreased the cost of these new devices, and at the same time, you get great battery life. But you lose some things too. You cannot run any apps that didn’t come out of the box. But there are exceptions, like Microsoft Office that was optimized to run on Windows RT. But other than that, you could mainly run Windows Store apps only which made it immune to Viruses and Malware.What is Windows 10 on ARM
At WinHEC 2023, Microsoft’s Terry Myerson demoed Windows 10 running on a Qualcomm Snapdragon 835 flagship chipset. People might say that this was nothing but a Windows 10 flavor of Windows RT, but it isn’t. Microsoft took the game a little forward. Windows 10 on ARM initiative was to bring desktop-like experiences to low-powered and cheaper devices. And by desktop-like experience, they mean that users can now run Win32 applications like full Adobe Photoshop on those devices. However, the speed and reliability won’t be better than conventional Intel CPUs, but these cheap devices will just get your work done.
Read: How is Windows on ARM different from Windows RT.Why is Windows 10 on ARM good for Microsoft
The desktop CPUs that Intel or AMD makes are based on x86 and x64 architecture. But mobile devices like iPhone, or other Android or Windows Phones used a CPU based on the ARM Architecture.
These ARM chips are cheap, portable, have greater connectivity capabilities with LTE and better battery life unlike the conventional chips from Intel and AMD.
So, with Windows 10 on ARM and support from its partners, Microsoft aims to make Windows 10 devices more affordable for consumers. They strive to bring 2-in-1 devices like Surface or Laptops but with ARM processors and hence Windows 10 on ARM.
The screen is instantly on whenever I pick up the device. I never have to wait for it to wake up, it’s just on.
Being always connected wherever I am whether I am in the car, airport or coffee shop, always being connected just feels like the most natural, safe and secure way to work with teams and be creative.
Lastly, the battery life is just awesome! I am finding myself charging it once a week. When I was using a wearable that needed to charge every day, I didn’t really rely on it. Once I moved to a Fitbit that only needed charging once a week that was game changing for me. Not carrying around power cords is liberating.How does it run x86 apps when it is made for ARM
All the things that I will be briefly described now will be coming from this video from a session about Windows 10 on ARM from Build 2023.
Now, these x86 apps run by using an emulation layer. This layer of emulation works magically to make it all up. The code for Kernal, drives and other inbox programs like Microsoft Edge, Microsoft Store, Calculator, Camera and other pre-loaded apps are written for ARM. The other x86 apps like Adobe Photoshop or 7-zip are executed using custom emulator from Microsoft called WOW or Windows on Windows. And for the x86 DLLs, Compiled Hybrid PE or CHPE is used to convert the code in x86 to ARM64. This makes all the magic to happen.
Did you know that the iPhone had a “Safe Mode?” Safe Mode on the iPhone has been apart of jailbreaking for years now, but many people still don’t understand it. If your iPhone is jailbroken, Safe Mode will be invoked when MobileSubstrate (the Cydia support framework) crashes.
Desktop operating systems, like Windows and Mac OS X, have had a “Safe Mode” for a long time. On the desktop, safe mode is used for removing corrupted processes that may be causing the operating system to not function properly.
The iPhone has a “Safe Mode” for that exact same reason. A simple Cydia app called “Safe Mode Launcher” allows you to invoke the iPhone’s Safe Mode with one tap. Let’s take a look…
The official description of Safe Mode Launcher,
“A simple utility to put your device into MobileSubstrate Safe Mode. You now no longer have to have SBSettings to put your device into Safe Mode! Useful if you want to uninstall a troublesome MobileSubstrate Addon.
This will install a new icon on your home screen. There are no options to configure.”
In SBSettings, Safe Mode can be initiated through the “Power” option. Safe Mode is listed alongside all of the other Power options.
Safe Mode Launcher sits as an icon on your home screen and boots your iPhone into Safe Mode with one tap. Once Safe Mode is running, you are safe to troubleshoot or delete MobilSubstrate addons that may be causing you trouble.
You may still be wondering why Safe Mode is important. A jailbroken iPhone boots into Safe Mode whenever a jailbreak extension is causing iOS to not work properly.
As you’ll notice in the Safe Mode menu, MobileSubstrate invokes Safe Mode to protect you from harmful processes running on your iPhone. For example, a newly installed jailbreak tweak could be (either intentionally or not) tampering with root files that could cause your build of iOS to be corrupted.
Once you jailbreak your iPhone, whether through SSH or other means, jailbreak extensions and addons have access to the root files of iOS. That can result in the occasional conflict when an extension oversteps its bounds or does not function the way it should at the root level.
If your iPhone has been entering Safe Mode frequently, you most likely have a MobileSubstrate addon that is not functioning properly. Safe Mode disables all jailbreak extensions, addons, etc. so that you can either troubleshoot or remove the process that you think may be causing the issue.
Safe Mode is pretty easy to boot back out of. Once your iPhone is in Safe Mode, you can reboot back to normal by tapping the “Restart” option in the MobileSubstrate menu. If you can’t find the menu, tap the “Exit Safe Mode” text at the top center of the iPhone’s status bar. A hard restart of iOS with the iPhone’s power button should disable Safe Mode too.
If it takes multiple attempts to get your iPhone out of Safe Mode, you have a serious problem. Remove or disable all of the jailbreak processes you can to see which is causing the problem.
Safe Mode isn’t pretty, and sadly it’s a symptom of jailbreaking that we all have to deal with. The good thing is that Safe Mode is there to protect your iPhone from harmful processes, so don’t get mad next time your Springboard crashes. Instead, by thankful that Cydia’s MobileSubstrate is smart enough to know when to protect you from a problem.
Safe Mode Launcher is available for free in the Cydia store. Give it a try if you want the freedom to safely troubleshoot your jailbroken iPhone.
Has your iPhone ever entered Safe Mode? Have you been experiencing the problem of your Springboard regularly crashing? If so, check your installed Cydia packages to try and find the culprit.
