#Difference between System Software and Utility Software

[booksinmythorax]

So, in the midst of... you know, everything, life at the library goes on and I wanted to talk about the difference between Libby and Hoopla.

For those not in the know, Libby and Hoopla are both apps/software that libraries can use to offer digital items to our patrons. Libby does ebooks (including graphic novels) and audiobooks.

Hoopla does ebooks, audiobooks, digital comics (weekly issues, not just trades or graphic novels), movies, TV shows, and music.

A little while back, my library system had to cut down on the number of Hoopla items patrons can check out per month. This caused a little bit of a stir - people like Hoopla! And they should! It's really cool! But the reason we had to cut back there and not with Libby was because the ways we pay for Libby and Hoopla are different.

Libby uses a pay-per-license model. This means that when we buy an ebook or audiobook on Libby, it's like we're buying one copy of a physical item. Except, because publishers are vultures, it's often much more expensive than buying one copy of the physical book - unless it's an audiobook, in which case buying the CDs might very well be more expensive than buying the digital license on Libby. That's why you might have to wait on a list for a Libby title that's really popular: we only have licenses for so many "copies". These licenses can be in perpetuity (i.e. you pay once and you can use that copy forever) or, more commonly, for a limited length of time like a year. Once that time is up, we decide whether to pay for the license for each copy again.

Hoopla uses a pay-per-circulation model. There's no waiting: once you, the patron, decide you'd like to check something out, you can do so immediately and we pay Hoopla a smaller amount of money to essentially "rent" the license from them. Cool, right?

Except that the pay-per-circ model adds up. If we have access to a brand new or popular title on Libby and Hoopla, and the Libby copy has a long waiting list, patrons might hop over to Hoopla to check it out immediately. If enough people do this, we might end up paying more overall for the Hoopla item on a per-circulation basis than we did for the license on the Libby item. That's why libraries typically limit the number of Hoopla checkouts patrons can use per month: because otherwise, we can't predict the amount we'll be paying Hoopla in the same way we can predict the amount we'll pay Libby.

Let me be clear: If a library offers a digital service and it would be helpful to you, please use it. Don't deny yourself a service you need or would enjoy in some misguided attempt to save your library some cash. We want to offer digital services, not least because ebooks and audiobooks have accessibility features that print books often don't. If your library has Libby and Hoopla and you get utility out of both, use both!

That said, if you're upset with the lower number of checkouts on Hoopla or the limited number of titles or copies available to you on Libby, you know who you should talk to? Your elected officials. Local, state, and federal. Because those folks are the ones who decide how much money we get, and what we can spend it on.

Don't go to them angry, either, because then we'll get scolded for not using the funds they "gave" us appropriately. (If you're a frequent library user, you might be shocked at how anti-library many local government officials already are.) Write your officials an email, call them, or show up at a board meeting and say you like the services the library offers, but you'd love it if we had enough money to buy more books on Libby or offer more checkouts on Hoopla. Tell them directly that this is how you would like your tax dollars to be spent.

If anybody has questions about how Hoopla or Libby work, I'm happy to answer them! Just wanted to make sure we had a baseline understanding.

What is the kernel of an operating system ?

You can think of the kernel as the core component of an operating system, just like the CPU is the core component of a computer. The kernel of an operating system, such as the Linux kernel, is responsible for managing system resources ( such as the CPU, memory, and devices ) . The kernel of an operating system is not a physical entity that can be seen. It is a computer program that resides in memory.

Key points to understand the relationship between the kernel and the OS:

The kernel acts as the intermediary between the hardware and the software layers of the system. It provides a layer of abstraction that allows software applications to interact with the hardware without needing to understand the low-level details of the hardware

The kernel controls and manages system resources such as the CPU, memory, devices, and file systems. It ensures that these resources are allocated and utilized efficiently by different processes and applications running on the system.

The kernel handles tasks like process scheduling, memory management, device drivers, file system access, and handling interrupts from hardware devices.

The kernel can be extended through the use of loadable kernel modules (LKM). LKMs allow for the addition of new functionality or device drivers without modifying the kernel itself.

So I've been thinking about when will the new mainline (this includes a potential remake) Fire Emblem game will be released.

So it's been confirmed that the Switch 2 is releasing this year. While the exact date when it'll come out is unknown, there's going to be a Switch 2 Direct on April 2nd. With this in mind, I'm predicting that the Switch 2 will come out either in October or November.

Now to what this post is about. FE has historically released the next mainline game within a 1-3 and a half year timeframe. That means there's most likely going to be an announcement for a new mainline game this year. If so, the game is most likely going to release some time between mid 2026 to late 2026. BUT, there's a chance that the new game will release in early 2027 for 2 reasons.

(This is all just speculation, so take what I'm about to say with a grain of salt).

One: There were leaks in early 2022 claiming that Engage was actually finished in 2021. While some of things the leaker claimed about the game turned out to be true (it being not being a remake, the protagonist having blue and red hair, and the concept of the Emblems), there is one thing the leaker was wrong about. They claimed that Koei Tecmo and their subsidiary studio Gust also worked on Engage. No where in the game's credits mentions Koei Tecmo, nor in any interview with the developers claimed their involvement. From what I could find, only Intelligent Systems worked on Engage. So the validity of the claim that Engage was finished in 2021 can be called into question. What I'm trying to say that there's a chance Engage was still being worked on during 2021 and 2022. Also, logically speaking, why would they just sit on an already finished game for roughly 2 years? This means, unless some other studio was working on FE18 while Engage was being developed, InSyst was putting most of their attention towards Engage. There is a chance that InSyst was also working on the next game alongside Engage, but I have a feeling that InSyst was much more focused on Engage's development.

Two: The whole controversy with Unity. Basically in 2023 Unity announced a change in how developers would be charged when using Unity and developers who use Unity are mad. Here's quote from this article that basically explains what the change would be and why developers are mad:

"Instead of charging developers a set monthly rate based on the number of users utilizing the software, it would implement a pay-per-download scheme that charged developers every time their game was downloaded. That meant instead of paying a flat, predictable rate to Unity, payouts could fluctuate, resulting in potentially higher fees. This news caused a massive uproar in the game development community with developers voicing their frustration on social media. Developers argued that the pricing model was implemented without adequate warning, forcing them to either pay the new fees that can’t be adequately budgeted for or make a costly and time-consuming switch to new software. They also claimed the per-download model could be exploited by malicious actors to run up fees on developers they don’t like."

Why am I mentioning Unity? This is because Engage is the first game to use a non in house made engine for FE, meaning that there is a chance InSyst will continue to use Unity for future FE games. The problem is because of the aforementioned Unity's new method of charging developers. While the same article did state that Unity has now since revoked this change, it still probably affected the development of FE18. This is because it took a full year for Unity to revoke the change meaning that there is a chance that InSyst changed to different engine, causing a delay in the progress of the game being made.

Now this part isn't that relevant to my speculation on when FE18 will come but I just wanted mention this: While the Switch 2 is going to be backwards compatible with Switch 1 games, there's still a chance the new mainline Fire Emblem game is going to be Switch 2 exclusive. This is all dependent on when FE18 is coming out. Also if Nintendo is going to treat the Switch 2 like a true next gen console and phase out making game for the Switch 1 into the Switch 2's lifespan, or if they're going to treat it like DSI and New 3DS situation and only have a few games exclusive to the Switch 2 while still making games for the Switch 1.

Anyways, this has been on my mind for a couple of days and just wanted to share my thoughts on the matter.

Out of curiosity (and of course please do not feel like you have to answer this)

How do you keep your story organized?

I use Miro Board to help me lay down my plot and timelines, but I’m always curious what other tools writers use to outline, organize and such for their writing.

Id love to also just create a post and have writers and artists add to it over time as a source of knowledge and help….but I’m not sure how to start it honestly.

i love this questions and for me it's SCRIVENER, baby, SCRIVENER

i'm using OCCULT PIECE as an example because it's a massive project and Scrivener absolutely helped me bring it to life (it finally corralled my brain into something manageable LMAO)

not sure how familiar you are with this software, but it combines a word processor with a file organization system so i can flip between documents within a work super quickly...keeps all my notes, drafts, and other docs at my fingertips

the column on the left shows the docs and folders i've set up to keep this massive AU project organized...i have folders for each story, with subfolders that have notes and chapters for each work, and then i have separate folders for worldbuilding notes, character notes, connections between stories, and similar...i expanded a bunch of the folders so you can see what's in 'em if you want a closer look

Scrivener also has a corkboard view so you can see your story elements all laid out, and you can move them around as you see fit, which makes rearranging scenes (should you choose to put separate scenes into their own text docs) very easy

i like this software for its utility but also because you pay for it once and then can transfer the license to different computers when/if you change to a new one, and you can get it pretty cheap using discount codes that come up pretty frequently (usually they're a NaNoWriMo prize)

i have never used Miro and IDK how it compares! will have to check it out and seeeeee

as for the post people can add to, do you mean like a Tumblr post with reblogs, or like a shareable document people can circulate and add to at will? would this be for a large collaborative story or universe or just general information? sounds cool either way! love it when a community comes together...

There are just two cables linking the remote Arctic archipelago of Svalbard with mainland Norway, providing almost all the data from polar-orbiting satellites to the rest of the world. And two years ago, they nearly stopped working.

Norwegian police images released in late May show the catastrophic damage done to one of the Svalbard fiber optic cables: the plastic casing slashed open, the cable exposed, and wires unfurled like a faulty electrical cord.

The unsolved January 2022 incident, which cut data flow from the SvalSat satellites and limited air traffic to the archipelago, is serving as a cautionary tale about what can happen when undersea cables—which underpin most of the global communications network—are cut. Yemen’s Iran-backed Houthi rebels did just that earlier this year when they targeted a key bottleneck between Asia, Africa, and Europe—after threatening to do so in response to Israel’s war against Hamas in Gaza.

The threat is not just limited to one or two areas. NATO officials believe that Russia has a decadeslong program to map out European undersea infrastructure as part of an effort to prepare the battlefield for a possible conflict with the 32-nation alliance.

“We know the potential is there to do damage if they would want to,” said a senior NATO official, speaking with Foreign Policy on condition of anonymity based on ground rules for interacting with journalists set by the alliance. “Part of Russian war planning is knowing where the critical infrastructure of your enemy is.”

It doesn’t take a huge effort by the Russians to get the information that they need to cause harm. Most of the pipelines are run by utility companies, and much of the data on where the cables run is in the public domain because of licensing requirements.

In response, NATO now has an undersea infrastructure coordination group that brings together military and civilian officials and has the power to convene top representatives from the private sector, based out of the alliance’s Maritime Command in the London suburb of Northwood.

“The question is connecting all the dots and creating a network,” the senior NATO official said of the information and intelligence exchange.

The ambitious effort is an attempt to use computing power to protect the vast undersea cable network that undergirds much of the global economy. Since it’s nearly impossible to patrol undersea all the time without an unrealistic number of submarines—especially across the Atlantic Ocean—the alliance has to rely on computers. Drawing on data from software interfaces and the cable and pipeline operators themselves, NATO allies are working together with the private sector to create a massive alert system for the thousands of miles of undersea infrastructure in Northern Europe, relying on sensors from the cables as well as acoustic sensors attached to wind turbines, which can be used to detect irregularities.

“NATO processes, I think, are sort of in a very early phase,” said Audun Halvorsen, the director of the emergency department for the Norwegian Shipowners’ Association (and formerly the country’s deputy foreign minister). “They are basically trying to map out the landscape when it comes to jurisdictions, when it comes to authorities involved. You are facing a huge range of different regulatory regimes for the industry around the undersea basin.”

The strategy of cutting undersea cables is almost as old as modern warfare. (The first trans-Atlantic cables had been laid a few decades earlier, in 1866.) Britain began cutting German undersea cables at the outset of World War I to sabotage communications—and the Germans happily returned the favor. When submarine telephone cables began being laid in the 1950s, during the early days of the Cold War, Soviet trawlers damaged underwater cables near the Newfoundland coast. The U.S. Navy alone owns more than 40,000 nautical miles of active cables on the seafloor.

But with fiber optic cables becoming the ubiquitous plumbing that underpins global communications and trade in the internet age, the vulnerability in the seabed is growing. Norway’s undersea pipeline network provides about 40 percent of Europe’s natural gas supply, with pipelines crisscrossing the North Sea to the United Kingdom and the rest of the continent along with about 500 underwater communication cables that carry roughly 97 percent of the world’s internet traffic—some of them extending all the way across the Atlantic Ocean. That’s as much as $10 trillion in financial transactions every day.

“It is less kinetic and more a way for the Russians to show the West that ‘we know you guys are quite challenged in securing that infrastructure,’” said Sebastian Bruns, a naval expert at the Center for Maritime Strategy and Security at the Institute for Security Policy at Kiel University in Germany. “They would be tackling the very seams of what ties our societies together.”

About 100 of those cables break globally every year—most by accident—and it’s basically impossible to protect all of that infrastructure, other than by adding even more redundant data cables or ensuring that more liquified natural gas tankers are waiting out at sea, providing another source of gas if there’s a break.

The concern for that infrastructure has led to the NATO effort, which began after the September 2022 attacks on the Nord Stream 1 and 2 pipelines that transport natural gas from Russia to Germany. Even though much of the data about where the cables are located is public, the sensor data that could determine whether a linkage is in danger of being cut is stovepiped far under the national level—meaning that it’s kept within the companies themselves. The United States alone has 85 licensed undersea telecommunications landing stations. And while many pipeline owners have taken into account the risk of corrosion and possible accidents, factoring for sabotage is less common.

Some experts believe that smaller groups of countries can move faster than NATO to protect the cables. In April, Norway and five other countries bordering the North Sea—Belgium, Denmark, the Netherlands, Germany, and the United Kingdom—agreed to share operational information to protect undersea cables and pipelines against sabotage. And the Council of the Baltic States recently met in Finland to condemn Russia’s hybrid tactics—incidents of sabotage that fall beneath the level of declared war, including threats to undersea cables.

Already, Russia is lashing out at Nordic countries through other means. Since Finland joined NATO in April 2023, Russia has been sending waves of forced migrants to their 830-mile-long shared border—nearly half of the entire boundary between Russia and the alliance—forcing Helsinki to shut down all of its crossings. Russia has proposed redrawing borders in the Baltic Sea, hit Sweden with cyberattacks, and even removed buoys on the Narva River that Estonia put in place to mark their maritime frontier.

“All of our economy under the sea is under threat,” Vice-Adm. Didier Maleterre, the deputy commander of the NATO maritime command, said in April.

The threat is heightened by a Russian submarine program that has resurged since the 2022 invasion of Ukraine, operating from the Kola Peninsula. But problems can also be caused by unintended anchor drag from commercial ships. The Hong Kong-flagged and Chinese-operated NewNew Polar Bear, suspected of damaging the Balticconnector gas pipeline between Finland and Estonia in October 2023, sailed away along the Northern Sea route with protection from a Russian icebreaker.

In the face of all the other challenges—shrinking navies, a resurgence in piracy, the Red Sea attacks—that undersea flank is exposed.

And officials say that Russia’s use of criminal and civilian networks—which are also deployed to create influence networks in mainland Europe—makes all of these tactics, including the sabotage of undersea pipelines, extremely difficult to pin on the Kremlin. The Russian surveys of the Baltic seabed, for instance, are carried out by ships with an ostensibly scientific purpose.

“We are still tied into this military-versus-civilian division of labor, whereas the Russians are much smarter using civilian vessels for military purposes,” said Bruns, the naval expert. “We are yet to find a solution for that.”

Scientists still understand relatively little about the form of the seafloor. So artificial intelligence is also being used to map it, providing another potential method to spot would-be Russian cable snappers. Some NATO countries and operators are even thinking about burying their pipelines in the seafloor, especially in the Baltic Sea, where the average depth is just under 200 feet. It’s already standard practice near most European coastlines, since it helps protect against bottom trawlers and ship anchors.

After the Balticconnector pipeline incident last fall, Norway began to do an inventory of its own undersea infrastructure, starting with oil and gas before branching out to map parts of the electrical grid and communications cables that ran underwater. Authorities were able to search nearly 5,600 miles of oil and gas pipelines.

“We searched everything,” said Gen. Eirik Kristoffersen, Norway’s chief of defense. “When we found something, we used our military experts to look [at], ‘what is this? Is this something that has been placed there? Is this something from World War II? Is it something that the fishermen dropped?’”

The ability to conduct such an extensive search stems from the infrastructure of the private sector. Norway’s energy industry already has preparedness mechanisms in place to help protect and repair undersea infrastructure for pipelines and electric cables, Halvorsen said, which is coordinated by Norwegian operator Equinor. It’s a model that Halvorsen believes has promise for communication cables, too. But across most of NATO, that capability is limited.

“There is basically zero capability in government hands to survey, repair, maintain, [or] replace any of this infrastructure,” Halvorsen said. “All that capability and capacity is for the civilian industry. So to protect this kind of underwater infrastructure, you need to have some kind of functioning interface between the government side … and the industry.”

How do you cope with package management? I mostly use python where it's literally just a single command. It took me over an hour to work out in c++

I'm going to be really honest and say the language package/build pipeline ecosystem is the single worst thing about C++. Memory safety isn't that big of a deal in well managed projects that utilize modern C++, pointer arithmetic ain't that hard once you take your time to actually understanding but the fucking mess that is the bizarre scene of package managers, build system setups and different ways of handling that in-between different codebases that rely on eachother? Nightmarish, unsolvable, literally not possible to workaround (see https://xkcd.com/927/).

What I'd recommend - look around at different repos for software you use and look how they structure their codebases, what buildsystems they use and see how it works for you! There isn't one-size-fits-all answer, unfortunately.

The way I program my own lil side projects, I use mainly CMake + CPM.cmake (a lil script that allows me to download github repos into my own source tree at a specific version and configure them for building) and make HEAVY use of CMake Presets.

As for what I'd recommend for you to try as a good starting point would be meson. It's great at getting you into a working program pretty fast and without much boilerplate.

Best of luck. There's a world of performant OOP goodness waiting.

Game Spotlight #4: Bulk Slash (1997)

Acquired Stardust’s first spotlight on a Sega Saturn game! Come join Ash as she takes a look at a game that never made it outside of Japan with 1997′s Bulk Slash!

The Sega Saturn has long been a fascinating subject to me, its rise and fall perhaps the culmination of a whirlwind of internal company politics and a rapidly changing landscape of both hardware and software. The attitude among gamers well into the 6th generation of consoles was as though its failure was a foregone conclusion not through any nuanced variety of factors, but because “duh, the Saturn sucked!”, the sort of take that time and hindsight allows to fester into a comfortable, easily repeatable opinion that you’ve heard enough people say that you too assume must be true.

But I’m happy to report that in my time experiencing a variety of titles on the Saturn in an attempt to satiate my longstanding curiosity, the Saturn doesn’t suck! In fact, the Saturn has been something that has consistently delivered games that surpassed my expectations. Daytona USA brought home a legendary racing title with a soundtrack as infamous as it is glorious (I’m personally of the opinion that Takenobu Mitsuyoshi is a genius and his involvement in anything always makes me happy), Capcom’s legendary run of fighting games was captured almost in its entirety on the Saturn, having ports of Street Fighter 2, the entire run of the Street Fighter Alpha series as well as Darkstalkers and what was at that time the entire selection of crossover games with Marvel, all of which looked significantly better than their Playstation port counterparts. SNK brought its own excellent array of arcade fighting game ports to home consoles in multiple King of Fighters releases alongside The Last Blade.

All of this is to say that the Saturn had something of a reputation as a system dominated by high quality arcade ports, which at the time was a significant thing to be able to say about a home console.  It’s a talking point that has settled into that comfortable space of easily repeatable factoid that may or may not be true, but in this case it is. The Sega Saturn was indeed home to high quality arcade ports, but something that’s lost in that conversation is just how many interesting, experimental and high quality titles don’t fit the mold of ‘taking something you played in the arcade and bringing it home’ - the Saturn-exclusive games. One such example is 1997′s Bulk Slash, developed by a little-known company called CAProductions in partnership with  since-defunct publisher Hudson. It was only the developer’s fourth game, and their first try at the emerging world of 3D games, a world in which conventional wisdom is that the Saturn struggled with.

Bulk Slash is something of a mix of Macross and Zeta Gundam, stylistically. An action game with a mech that transforms into a jet, featuring a story about military factions causing trouble of the genocidal variety to avenge alleged oppression. Switching freely between mech and jet forms, the main character Cress pilots his conspicuously Gundam-like mech in a campaign to defeat the Gardona military which has managed to wrap up his childhood friend Riizen into its ranks through political events prior to the start of the game. Playing out across seven stages each with different goals and a boss fight to close out the mission, the player can collect various score-boosting items as well as health recovery items and weapon upgrades not unlike Contra or Metal Slug. Bulk Slash controls remarkably well for a game featuring both a humanoid combatant in its mech running around shooting and throwing grenades as well as a jet, all while not utilizing a secondary right thumbstick for camera controls, which are instead relegated to shoulder buttons on the controller. The action is fairly fast paced with an impressive frame rate, only slowing down in instances of large chained explosions going off in certain circumstances. Just as well, the graphics and art style are quite good (almost reminiscent of the rise of the recent ‘2DHD’ art style), and the soundtrack very fitting for its time though not especially memorable.

Layered into the fairly standard (albeit impressive) action gameplay is the ‘M.I.S.S’ mechanic (which stands for ‘Manageable Intelligent Support System’), a collection of 7 NPCs which must be located in each of Bulk Slash’s 7 stages serving as navigators for Cress, giving direction on the location of targets and bosses. Each of these NPCs are girls of various design, occupation and personality, including one who throws lots of English phrases into her otherwise Japanese speech which is very entertaining. Bulk Slash’s M.I.S.S system is more than meets the eye however, adding light dating sim mechanics into the game, with all 7 girls having their own endings and CG art unlocked depending on the player’s score upon defeat of the game’s final boss. It’s a small thing but really goes a long way in providing an experience that’s just varied and customizable enough. Having only 7 missions, the game is not especially long and only saves after successful runs through it after defeating the final boss, which itself has a boss gauntlet before it that can be a little rough while you’re still getting used to the game but if you put time into the game you’ll soon be able to defeat them without taking too much (or even any) damage, assisted by the fact that each of them seems to have timings for which you can score a critical hit, either dealing heavy damage or sometimes even outright destroying them in one blow.

Bulk Slash, as previously mentioned, was never released outside of Japan but the game is relatively simple to navigate and understand, being communicated very well visually. There was also a recent English translation patch which is a little hit or miss translation and localization-wise, but otherwise should assist people who don’t speak Japanese in understanding the story and character interactions, which is surprisingly good (and surprisingly dark at times) and a clear love letter to Universal Century Gundam.

Bulk Slash was the second Saturn game I ever played (after the all-time classic Daytona USA, for those wondering), and I’m glad it was such an early stop in the tour of the Saturn library because it shows off a lot of the strengths of the platform as well as bucking some of the usual talking points about the system, such as not doing 3D very well. It also layers in some of Japan’s big gaming trends at the time, such as dating sim elements most that most prominently and recently (at the time anyway) helped make Sakura Taisen a big hit on the platform just a year earlier. It’s a shame Bulk Slash never saw release outside of Japan as it would probably have done fairly well and be fondly remembered, and it’s definitely the sort of game that feels as though it would be pretty popular were it to have been an indie game releasing today.

A gem hidden among the stones, Bulk Slash is undoubtedly stardust.

VPS: What is it?

First, let's get a grasp on what virtual private server hosting (VPS) is and how it operates before we move on to analyzing the distinctions between managed and unmanaged VPS hosting. Virtual private server hosting (VPS hosting) is a method of delivering hosting services in which a single physical server is partitioned into several virtual servers. The processing power (CPU), memory (RAM), and storage space utilized by each virtual server are distinct from those utilized by any other machine.

In spite of the fact that these virtual servers are established on a single physical system, they conduct their operations independently of one another. As a result of the shared underlying hardware, each user is provided with their very own dedicated virtual server, which is analogous to having a dedicated physical server but at a lesser cost. Each user's data and applications are kept separate and secure, exactly as if they were running on their own physical server because the servers are geographically separated from one another. This ensures that the servers are isolated from one another.

What exactly is a managed virtual private server?

As the name suggests, managed virtual private servers (VPS) mean that you do not have to worry about the responsibilities that are associated with the server, such as administering and maintaining your server. Your web hosting provider will be responsible for monitoring and managing all of the server's functionality. In spite of the fact that you are familiar with the technical features of the server and how to manage it, outsourcing the management of the server to your web hosting provider will alleviate the stress of carrying out all of the procedures.

The specialists who work for your web hosting provider take full responsibility for the resources on your server. They also keep a constant watch on your server to identify any potential issues, and they are responsible for implementing any necessary updates and upgrades. In particular, for users who do not have a lot of time to devote to duties that are related to the server.

The Benefits of Using a Managed Virtual Private Server-

Managed VPS hosting, also known as virtual private server hosting, provides a multitude of advantages, particularly for customers who are more concerned with the development of their applications or businesses than with the management of server infrastructure.

It is recommended that you go with unmanaged hosting if you are a professional in the field of technology, have experience maintaining servers, and have the ability to devote sufficient time to operating a server. If, on the other hand, you are a novice or a startup that has to concentrate on expanding your business, then managing a virtual private server (VPS) can be a laborious task.

The technical assistance that you receive with managed virtual private servers helps you save crucial hours. This enables you to concentrate on your primary goals, which may include managing your staff, making income, establishing relationships with customers, and other similar activities. Conversely, if you are concerned about the costs and have a good understanding of the server and how it is administered, then an unmanaged virtual private server (VPS) will be a better option for you.

Conclusion-

Users believe that it is dependable and risk-free to obtain a managed virtual private server (VPS) from a hosting provider, despite the fact that managed VPS is somewhat more expensive than self-managed VPS. This is because the price of managed VPS has decreased over time. It is also better to choose managed hosting if the procedure of setting up the server is going to have an impact on your company and take a significant amount of time.

Another aspect that should be taken into consideration is safety. It is not a bad idea to go with an unmanaged virtual private server (VPS) if you are willing to assume full responsibility for the safety of your server and be sure that it will be protected from the dangers that are there on the internet.
