Hello guys, you may have seen about this feature in the features in your domain. DNSSEC as the name combination from DNS & SEC, The first time I got to know it I thought it must have to do with DNS security in a way from the word DNS and SECurity right… Hehe. But actually dnssec stands for “Domain Name System Security Extension” and don’t worry i mistaken either. In short way, this feature is a form of authentication security from the domain to the server, if the data that communicates from the domain and the server shoul validate if the data is really from the appropriate server. basically, it uses the some kind of key sign so to pass each other that it becomes more secure.
Ok, right off the boat, to use DNSSEC on Cloudflare is really easy, just copy and paste the key from Cloudflare to your domain manager (depending on your domain registrar). For example, you can log in to your Cloudflare dashboard and look for the menu as below.
Select the DNS tab > Scroll down until you find this menu
After you find the menu as above, then you can immediately click “Enable DNSSEC”. Then you will be presented on the page as below.
Key view for DNSSEC
After the display appears as above, then we will enter the key code above to connect to our domain manager, where we buy the domain. For example, if you buy a domain at GoDaddy, Namecheap, Bluehost.. etc. then you just enter it in the domain manager then select DNSSEC menu at your domain registrar. Below is an example of the registrar that I use, the name is Namesilo, so for example, as shown below.
Input all according to the details on Cloudflare
As you guys above, we just need to enter the key code obtained from Cloudflare in the DDNSSEC menu on our respective registar. Make sure everything is correct and if successful on the DNS tab and the DNSSEC menu will appear as below.
DDNSSEC is already active
Well, it’s really easy, right, with this DDNSEC firut adding security to our DNS so that it is not easily hijacked (if im not mistaken, it’s called DNS forged). So your domain is more secure. Good Luck!
Do you have gadgets, laptop phones, printers? then you must have been aware of the USB interface. Yep, usb stands for Universal Serial Bus which is used for data and power transmission in today’s technological devices. In line with its development, this USB interface has undergone many physical changes as well as and for each change also has its own compatibility2. both from the USB version (e.g. USB 1.1, 2.0, 3.0, 3.1) and also the power output that can be streamed on the interface. okay let’s just start from the first one:
USB Type A
USB Type A Port Display
It is the most common type of USB used on many devices, usually used as a base. This USB Type A for now also has 2 versions, namely the standard type and the SuperSpeed type. For the standard type it has 4 pins on its port that supports up to USB 2.0 bandwidth (480Mbps) and in Super Speed it has an 8 pin connector that supports up to USB 3.2 (5Gbps-20Gbps).
USB Type B
USB Type B Port Display
This type of USB is usually used in printer devices, scanners and which is somewhat similar to the scenario. This USB is a rather wide box that can be compatible with USB 1.1 to 3.x data transmission depending on the other end (usually Type A).
USB Type C
USB Type C Port Display
It is the latest version of the USB interface whose use can be reversed up or down because it has symmetrical dimensions. This type supports bandwidth up to USB 3.2 (20Gbps) and it looks like it will also support USB 4.0 in the future. USB Type C also supports power delivery (depending on the manufacturer wants to prioritize bandwidth or power) which can deliver up to 240W of power (*for now). So it is not surprising that this interface is the most commonly found for all devices today, be it laptops, smartphones, monitors, tablets. etc. Because it is the most versatile USB interface for both high bandwidth data transmission and high power transmission.
Mini USB
Mini USB Port Display
Is a USB interface that is often used before switching to a capacitive screen. we can find it on old mobile phones released in 2006 and also consoles such as PSP. Supports bandwidth up to 480Mbps or USB 2.0. In 2007 it was considered obsolete because its dimensions were too large for the latest generation of thinner mobile devices, then subsequently replaced by micro USB which we will discuss below.
Micro USB
Micro USB Port Display
Next is Micro USB, this type of port is quite long used until now it is still used even though it has been widely replaced by USB Type C. The advantage of this port is that its dimensions are smaller than mini USB and have the same features as Mini USB.
So that’s the all interface that i know (i think). Actually, there is another Micro USB SuperSpeed which is a high-bandwidth version of micro USB that can support data transmission up to 6Gbps which is commonly on the hard disk enclosure, which is currently also starting to be replaced by USB type C. Ok, maybe that’s it, hopefully it helps!
Have you ever wanted to buy a microphone but you are confused because of the type, the microphones sold in the marketplace generally have 2 types like this title. So both Dynamic and Condenser Microphone have different ways of working & different needs as well. Before we discuss the differences, we start first from the similarities, a part that make the mic able to pickup our voice, that is the Diaphragm (diaphragm). So diaphragms are simply like small speakers made of sheets (usually plastic), magnets and copper windings (coils) as conductors of electricity. The way it works by listening acoustic vibrations that will cause the Diaphragm (diaphragm) to vibrate which will then be converted into electrical energy.
Diaphragms (diaphragms) are generally 2 types:
Large Diaphragm ( large diaphragm)
As the name implies, this diaphragm has a large size with inconsistent polar pattern characteristics but has a high sensitivity that allows it to capture a wider spectrum of sounds. Microphones with this diaphragms can be found in the studio, recording vocal sounds, bass drums and sometimes for room recording to get a more vintage sound.
Small Diaphragm (small diaphragm)
Microphone with this Diaphragm is also commonly called “pencil microphone” which is very powerful for capturing sounds with high frequencies and has a consistent polar pattern (characterized by the size of the diaphragm and its mass / weight). Therefore you will usually find this microphone recording on snare drums, pianos and acoustic guitars.
OK here we already know the basis of the microphone, the next thing is . What is the difference between a dynamic microphone and a condenser microphone?
Dynamic Microphone
Dynamic microphones can generally pick up various sound signals without fear that the Diaphragm will be damaged due to the low level of sensitivity and has a high built-in gain, so you will usually find this mic for live scenarios / use in open spaces directly. Even so, this microphone is also suitable for studio use for drums, brass instruments, guitar amplifiers. etc. Usually to catch a loud sound.
Condenser Microphone
Unlike dynamic microphones, Condenser Microphones are usually more sensitive to sound vibrations. So the use of this microphone if you blow your mic too much on the capsule diaphragm condenser, then the sound produced will be distorted (due to its sensitivity). This mic can also be used for live scenarios sometimes, but this mic is often used in studio rooms where you can get a sound with a wide and more natural tone range.
So which microphone is suitable for me?
As explained above, it all comes back to your recording needs. If you want to record loud sounds such as loud vocals, snare drums, keyboards and metal instruments then I recommend choosing Dynamic Microphone. But if you want to record sounds that are not loud such as vocals, bass drums, acoustic guitars, pianos then condenser microphone in my opinion will be more suitable.
It is very common that all CPU/GPU/SOC chips can be very hot and therefore every purchase of a semicondutor chip will be equipped with a cooling system for PCs, mobile phones, servers and other electronic equipment/components. That is why the importance of using a cooling system that suits each need, which for PC will be divided into two category, which is Liquid or Water Cooling & Air Cooling. After that, the question arises which is the best of the two cooling systems?
Well, for this question, the answer is maybe you can guess it, it depends. Why does it depend, because each cooling system, both liquid cooling & air cooling, has its own advantages and disadvantages that you can consider. For that we will start from the basics, how the cooling of each system works, starting from the heat transfer from beginning to end. We start from the most common, the air cooling or cooling systems with air as medium.
CPU Cooler from be quiet!
Air Cooling / Cooling System with Air
The air cooling system is the oldest system and until now it is still used because of its effectiveness & cheaper because it uses air as a medium. Furthermore, cooling air coolers will usually be easier to install and apply, even by beginners. Generally, air coolers can handle CPU / GPU cooling from low end system to high end as well (the optimal one usually uses a combination of base and copper pipes connected to an aluminum heatsink). The disadvantage of this system is the size of the heatsink which is rather large and wide (although there is a low profile version) when compared to a liquid cooler, it has such as a water block that is in direct contact with the heat source (more space-saving). So sometimes for air cooling system it’s not very good in terms of PC CPU aesthetics (subjective).
CPU Cooler dary Corsair Hydro
Water or Liquid Cooling System
Water Cooler or also known as Liquid Cooler is the latest cooling technology system that involves liquid to transfer heat directly through the Water Block / Metal Base which is in direct contact with the CPU / GPU. This method is allegedly more efficient in transferring heat from the chip core, although the high end air cooler can match the efficiency of the liquid cooler in terms of lowering the temperature for improved performance this day. At this system, the liquid cooler requires a radiator to remove heat from the liquid which later when it cools down will flow again to the chip to absorb heat again (Many radiator has various variants from 120mm, 240mm, to even larger ones). With this system, the liquid cooler can absorb heat and dissipate heat more optimally, so the chip will have headroom to improve performance again. The disadvantage of Liquid Cooler is that it is more expensive than Air Cooler, despite the installation of Liquid Cooler can make your system better in terms of aesthetics (because it does not use a heatsink in a PC) and again your PC will be quieter (not noisy, because there are fewer fans installed).
So which system is suitable for me? So the point will depend on your budget & the preferences of the system you want to achieve. If you have a budget that is not too high and don’t bother about noise & do some overclocking on your system then Air Cooler is the answer. But if you want the best performance both for overclocking, silent and aesthetic systems, maybe you will like liquid coolers.
Hello everyone, have you ever wanted to know the difference from the various internet cables or also called LAN (ethernet cable) the most used cables to connect our PC today? When we search at the marketplace, there will be a lot of choices from the most expensive to even the cheapest, but are they all the same? The answer is NO! , each type of cable has its own data bandwidth with different specifications. Well, here I will explain one by one from cat5 internet cable to Cat 8. OK, let’s just start:
1. CAT 5 (CAT5) Cable
Cat5 cables were first introduced for high-speed data transmission made with multi-pair cables (4 pairs of twisted cables, in the amount of 8 wires). This cable can handle a bandwidth of 10/100Mbps and can be set as long as 100 meters. This generation of cables is also often referred to as Fast Ethernet. In general, Cat5 cables are designed to handle up to 100MHz.
Cable frequency: 100Mhz Bandwitdth Max: 100Mbps Max Length: 100 Meters
2. CAT 5e Cable (CAT5e)
Cat5e cables were introduced as an “enchance” version of the previous version with the improvisation of a stricter standard, the IEEE Standart. The Cat5e version has less noise than the previous version which has the potential to reduce crosstalk (Crosstalk is interference interference from other adjacent cables). Unlike Cat5, cat5e versions can handle up to 1000Mbps more bandwidth and are often referred to as gigabit ethernet. At about the same price as the Cat5, the Cat5e has replaced the Cat5 now (the Cat5 is no longer in production at the moment). For speeds of 1000Mbps/1GBps, Cat5e cables run at frequencies of 100-250Mhz.
Cat6 cables were introduced as a new generation, featuring better wiring specifications to avoid crosstalk and less noise than previous versions. The updated wiring design can be seen physically, FYI Cat5e version has 1.5 – 2 rounds of spiral cables per CM, but in other hand Cat6 has a minimum of 2 rounds of spiral cables or more per CM & for additional for Cat6 there is also a separator per pair of cables. The Cat6 version is designed to be able to handle 1Gbps bandwidth at a distance of 100 meters with a minimum frequency of 250Mhz. If the Cat6 cable has a length of less than 55 meters, the supported bandwidth can reach up to 10Gbps (depending on the level of crosstalk & noise on the cable). For the general price, Cat6 is slightly more expensive than Cat5e due to stricter cable specifications.
Cable frequency: 250Mhz – 550Mhz Bandwitdth Max: 1Gbps at 100 Meters / 10 Gbps at 55 Meters and below Max Length: 100 Meters
CAT 6 Cable (CAT6a)
Cat6a cables are introduced as Augmented versions when compared to previous versions, in cat6a versions have a thicker protective layer that reduces crosstalk interference and noise that occurs. With the specifications developed, Cat6a cables can handle bandwidth of up to 10Gbps on 100 meters of cables running with a frequency of 500Mhz. Cat6a generally has a slightly higher price than the Cat6 version & the Cat6a version has a thicker shield (the downside of cable is less flexible), Cat6a Cables are suitable for use in industrial / commercial environments.
Cat7 cables were introduced as the latest generation of the Cat6a version which also supports 10Gbps bandwidth, but in addition to that Cat7 physically also gets better shielding protection than the previous version with a newer “Class F” standart. With the addition of additional shielding, the Cat7 has less crosstalk interfence dampening & noise when compared to the previous version. With this feature, Cat7 cables can accommodate bandwidth up to 10Gbps stably with a frequency of 600Mhz. Even with the new specification standards on the Cat7, Cat6a performance has identical performance to the Cat7 at a lower price than the Cat7. In general, Cat6a is often used for Surveillance / Multimedia systems (surveillance systems related to CCTV and Audio Visual cameras) be it Cat6a STP / FTP, Cat7 is generally more suitable for use in Data Centers and corporate networks that require stable data transmission.
Cable frequency: 600Mhz Bandwitdth Max: 10Gbps Max Length: 100 Meters
CAT 8 (CAT8) Cable
Cat8 cables were introduced as the latest generation of previous versions but so were the most different from previous versions. Cat8 cables can handle 25Gbps to 40Gbps bandwidth with a frequency of 2000Mhz. Even though it has an amazing bandwidth speed, the cat8 cable length is only limited to 30 meters. Although very different from the previous version, just like the previous version of the cable, the Cat8 Cable is also compatible with the previous version. For now, cat8 cables are the fastest data transmission cables that use the RJ45 connector.
Cable frequency: 2000Mhz Bandwitdth Max: 25-40Gbps Max Length: 30 Meters
So that’s the comparison of ethernet cables on the market today. My advice is, if you are confused about which one to choose, I suggest buying it as needed and make sure your device supports the data transmission speed according to the cable specifications above.
Hello readers, you may used to see at the specifications of the cellphone, there must be an SoC (System on Chip). A smartphone buyer who prefers the performance of a smartphone must be the first time to see what SoC to use after that, how much it costs… Haha. That’s right, SoC is a benchmark for the performance of a new smartphone after that it is followed by others such as OS customization, screen resolution, built-in software. etc.
So what exactly is an SoC, what is the difference between the cpu in our laptops and PCs? So, if you say that SoC is the CPU of a smartphone, it’s true because SoC also includes the CPU of a smartphone, but SoC is more than that. SoC also includes GPU (for graphics process), ISP (preprocessing camera quality), Modem (connectivity process).. etc. SoC it is also often called a chipset because it regulates the CPU, GPU, DSP, ISP, Modem.. etc simultaneously.
Therefore, according to me, the selection of the SoC is quite important because it includes many factors. For example, if you are a multitasking user, choose an SoC with a strong multicore CPU, if a user for gaming chooses a strong GPU, if you are a video or photography user, you can choose the latest ISP (Image Signal Processor) that can meet your criteria (example: record 4K 60fps video, or 48MP super high resolution image photos for example).
Now there are already many SoC manufacturers that you can choose from, and the most famous Snapdragon, Mediatek & Exynos. Here the manufacture that maybe you doesn’t know, there are Allwinner, Rockchip, Intel, Marvell.. etc. All of these SoC brands have many SoC products ranging from entry level to high end and various platforms as well, there are tablets, lightweight laptops, convertibles, TV boxes. etc.
The point is that SoC is a vital part of a smartphone (and others), whether you use it only for social media or games, it will feel very impactful. Even so, according to me with the current technological developments, SoC will continue to develop and maybe later there will also be new features like in RTX (nvidia ray tracing) or tensor cores (Processors for AI computing) maybe… wkwk
That’s it, it’s been a long time since this writer went to digress where.. wkwk May it be useful tho!
Hello Man, Have you ever thought about buying a computer but confused about which one to choose? Before we get into the next stage now let’s think about it first, what is the purpose of buying a computer for? Is it for school, college, indoor work, field work, gaming or maybe include some of the ones I mentioned earlier? Well, from the question above, it will make it easier for us to choose the right computer.
Okay, let’s just start if that’s the case, here I assume you have the same budget for the three options below, and we just start with the choices:
Desktop Computers
By choosing a desktop computer you prioritize performance and the ability to upgrade hardware but sacrifice mobility. Desktop computers are suitable for those of you who use a stationary computer, it should be in one place and do not move. On the same budget, desktop PCs offer better performance when compared to laptops or tablets, then in addition, desktop computer offering good upgradeability with versatility hardware according to your needs, this day you can build a PC according to your own needs / desires. Desktop PC performance is the sweet spot if you need the best computing power that can be relied on even for heavy work loads.
Laptop
By choosing a laptop you prioritize mobility with few upgrade options. Laptops are suitable for those of you who use computers not only at home but can be carried anywhere, though they are usually equipped with batteries that last not too long but are suitable for mobile computing that is not too long (an average of 2 to 3 hours on load). Even though with a battery not too big you can overcome it by charging in a certain place if it supports it and because of this feature usually the laptop will be heavier to carry than a tablet or convertible laptop. Although not as fast as a desktop PC with the same budget, laptops still have decent performance for a work load not too heavy.
Tablet / Convertible Laptop
Choosing a Tablet / Convertible laptop means that you prioritize mobility without upgrade support. Tablets are suitable for those of you who travel a lot or do computing activities without / few places need to charge, usually tablets are equipped with a powerful battery (usually lasting 5 – 8 hours) so you don’t have to worry if your computing activities are interrupted. Although with great battery support this also has an impact on performance because tablets are more power efficient than laptops, with the same budget tablets are enough to run light to medium wokload. In addition, another advantage of tablets is that they are lightweight and do not require a large space compared to laptops.
With the list above, we can conclude that each device above has its own disadvantages and advantages and is intended according to the needs of the customer’s own characteristics. Whether it’s for gamers, work or entertainment, everyone has different computing needs.
Have you determined which one is suitable for you?
Hello Man, with the growth of fabrication technology that is getting smaller and smaller, it remind me of my first computer with a Pentium 2 CPU from Intel which is 250nm and when compared to today (2020 at the time I wrote this) it is now only 7nm. Just imagine how small it is until it is 35x smaller than 250nm. Ok enough nostalgia, but related to earlier, now with smaller fabrications, manufacturers can embed better integrated GPUs in each generation.
You must be know the PS4 or Xbox One game consoles is using integrated graphics, if you don’t know that the console uses an integrated GPU / APU and not only that the PS5 and Xbox Series X generations also follow with newer technology of course. But for PC, the current APU / Integrated GPU still can’t achieve even entry level GPU performance (Such as Vega 8 & GT 1030). Hopefully, in the future, Integrated GPUs can be more varied from low end to high end.
So what if it’s a GPU discrete? in my opinion discrete GPU compared to iGPU, discrete GPU is more independent in processing graphics on a PC so it does not affect CPU performance which makes both run optimally. Meanwhile, the iGPU because it attaches to the APU/CPU will certainly reduce the CPU allocation ration on the APU chip so that it makes both of them not too optimal and also because each chip has a power limit for every processing that occurs sometimes there will be a bottleneck / overheat if the CPU and GPU do heavy tasks simultaneously.
So which one is suitable for you iGPU or Discrete GPU? So here I will break it down into 2 points:
Integrated GPU
Integrated GPU is suitable for those of you who need a budget-oriented device. So because the iGPU is a bundle with a CPU, the cost of APU is usually more economical (and also power efficient) because you don’t need to buy a GPU anymore and you can also still upgrade the discrete GPU in the future. Even so, APUs have CPU/GPU performance that is not too optimal compared to dedicated CPUs/GPUs.
Discrete GPU
Discrete GPU is suitable for those of you who need a performance-oriented device. So because the CPU and GPU are dedicated or have their own space. CPU/GPU performance becomes more optimal because it does not share the chip allocation and each hardware has its own power limit. Even so, generally discrete GPUs cost more than APUs.
Have you ever edited a photo / video or looked at the screen specifications to find an aspect ratio like in the title of this article, be it 16:9 16:10 4:3 21:9 etc. Maybe someone doesn’t know or maybe I don’t know, anyway I’ll explain to you the various aspect ratios and naivety in general. Ok, let’s start the list:
Aspect Ratio 16:9
We start this list with the most commonly used aspect ratio for video, 2017 cellphone screens and below ,and monitors. This aspect ratio is often used for the creation of other content videos because of the screen devices that mostly support it. For example, the majority of videos on Youtube use 16:9 ratio-based videos with resolutions that follow be it 720p, 1080p, 1440p or 4k. And in addition, when we take videos or photos on the camera (cellphone or dslr) there is always a resolution option at 16:9.
Aspect Ratio 9:16
Actually, this aspect ratio is a 16:9 aspect ratio, but on vertical side. This aspect ratio is a portrait version of 16:9 which brings it to 9:16. We often find its use when we take pictures and videos in portraits and now there are many platforms that support this aspect ratio such as Youtube, Instagram and TikTok (now it’s booming). Although many platforms that support the content are not as much as the landscape version.
Aspect Ratio 4:3
For the 4:3 aspect ratio, it has actually existed from antiquity since the beginning of tube TVs and LCD flooding the market. This aspect ratio is also often encountered when we see old videos on YouTube or your old photos. Even so, this aspect ratio is also still used on your camera, be it a cellphone or dslr, this aspect ratio is always there and is an option when you want to take photos or videos.
Aspect Ratio 1:1
Next the aspect ratio is 1:1 or square and this aspect ratio is the same age or older than 4:3. Almost the same as 4:3, we still find this aspect ratio in content on the internet. On your camera, there is also usually an option for this aspect ratio, both for shooting and video.
Aspect Ratio 16:10
This aspect ratio existed before 16:9 and is commonly used on mobile widescreen monitor screens, and tablets with slight widening. Although rarely there is still some content that uses this aspect ratio, both photos and videos that we can find today. This aspect ratio has been rarely encountered since 2008 and is an upgraded version of 16:9 with a slight widening.
Aspect Ratio 21:9
How about a lot of what I mention and for aspect ratio this is often called ultrawide on the monitor and for content creation call this the aspect ratio cinemascope because it is often used for cinematic videos. According to its use, this aspect ratio is often found on computer monitors with the name ultrawide monitor and on smartphones we can also sometimes find it in the flagship series.
Aspect Ratio 19.5:9
The last one is an aspect ratio of 19.5:9, and the latter we often find in the aspect ratio of your smartphone. Although it is relatively new but because many industries have adopted this aspect ratio for the screen size of their mobile phone production this aspect ratio is increasingly booming, and now many content creators are starting to use this aspect ratio for their content creation because they are estimating for mobile phone users and also even though users commonly use aspect ratio of 16:9 or 16:10, users can still watch videos with a little black bars above the bottom but it doesn’t matter.
Well maybe that’s just the aspect ratio that is commonly used today according to what I can mention, so the point is that each aspect ratio has its own use and purpose.
Currently, with the development of video editing technology, it can also be done on the Android OS. Although when compared to Video editors on PC, video editors on Android have limitations on several features, but video editors on Android now little by little adding more editing features just like on PC. And of the many applications on Android, here are some of the applications that I think are the best for now:
Kinemaster
Yep, I put kinemaster in the first list of this list. Kinemaster has very complete features compared to other editors which, among others, can make multi-layer video editing more than other applications. Furthermore, for my opinion features such as greenscreen PiP (Picture in Picture), transitions, audio filter, greenscreen.. etc which I think the features are more mature than others. And finally the community of kinemaster in my opinion is the biggest, you can easily find tutorials or ask questions through kinemaster editing forums.
Powerdirector
Moving on to second I think PowerDirector deserves to be crowned number two. As a consideration I chose this application is the import and rendering support up to 4K 60fps. In addition, although the features are not as complete as kinemaster, PowerDirector offers core features with some restrictions such as limiting the number of layers and simpler layer customization. Even so, the powerdirector has an interface that I think is easier to master and its features are relatively close to being able to match the kinemaster.
Viva Video
Thirdly there is Viva Video with resource features that vary greatly from video filters, audio and many other templates making viva video worthy of being ranked third in my version. With the same core features as the video editor above Viva Video prioritizes a user friendly interface and its many feature resources are with beautification making it on a video editor that is suitable for the majority of girls (which guys also exist). One of the viva video features that are not in other video editors is beautify, which can make your face better looking by importing your video and adding the beautify effect in this application.
Filmora Go
With the advert go in it filmora go is indeed devoted to video editors that are simple & problem solving. Filmora go in my opinion is simpler than the video editor above and only offers important feature features with minimal customization even so filmora go is specifically for fast video editing. Even so, filmora Go you can rely on for your daily light editing.
So guys, which of these android video editor applications do you think is the best or do you have other choices besides on this list? Well this list is an experience from what I’ve known all along and maybe it could be wrong CMIIW. So the point is to choose any application that you like and are comfortable to use because what I recommend is not necessarily suitable for you. Happy editing guys 😀
