There are many reasons why computer users compress their files. The most common reason is to conserve storage. In Linux, there is quite a selection of compression tools available. There’s tar, gzip, bzip2, xz, and a lot more.

Comments closedHTOP is an interactive process viewer similar to the top command installed in all Linux distributions. It is a free (GPL) process viewer based on the ncurses library. In the most basic sense, top and HTOP are the same except for certain extra functions such as the vertical and horizontal scroll. HTOP also displays all processes, command lines, and process trees running in the system. Unfortunately, HTOP is not installed by default in CentOS 7. There are two ways to install it. The first way is through the epel repository. The other is by compiling the facility from source. This article focuses on the latter and demonstrates the process in detail.

Leave a CommentThis article details the steps to Build a Centos 7 SMS Gateway from Source. This exists because the steps described in the previous article “Build a CentOS 7 SMS Gateway with Gammu” is fraught with issues. Lest it be misconstrued rather unfairly, what I mean by the term “fraught with issues” is that it works but not totally. In the case at bar, the gammu-smsd utility is missing from the rpms or more succintly, the terminal prompts – gammu-smsd: command not found.

Comments closedTwo years ago (2014), I wrote the article “CentOS 6.5 Configuration Tips” to document the steps I take in building a CentOS 6.5 server. Through the years, it has saved me a lot of time in rolling out custom CentOS builds for client requirements. Truth be told, the article is a life saver. It allows me to build, customize, deploy, and deliver servers consistently all-the-time every time. Likewise, my coworkers benefit from the article because it provides a simple guide on how to install frugal CentOS 6.5 builds. Of course, at the end of the day, when they give me a properly configured server build, I benefit.
However, like everything else in the IT, things change quite quickly. Usually, there are minute changes here and there which may be annoying at times but are totally tolerable. But there are times, such as the case at hand, where the annoyances turn into complete nuisances.
To cut the story short, CentOS 7 is a substantial departure from CentOS 6.5. This departure makes the 2014 article on “CentOS Configuration Tips” partially obsolete. Thus, a new guide is warranted.

Leave a CommentA calendar software is an essential part in any person’s life. It is a vital time management tool for students and professionals who live through dizzying arrays of activities day in and day out. At times, they are seen as sanity-keepers because they make sense of things which would seem insane for any person to undertake.
Calendar software applications are not new things, they are not sui generis — a thing or class of their own. In fact, a cursory Google search results to hundreds of millions of results — literally. That being the case, it is no longer relevant to discuss how to use them. After all, a calendar is a calendar is a calendar. However, syncing them with a desktop calendar application is a totally a different matter. This blog post on how to sync Google Calendar and Mozilla Lightning.

Comments closedThe Family Code of the Philippines specifically dedicates a whole chapter on the subject of “Donations by Reason of Marriage.” The chapter contains four articles which, like most law books, do not attempt to make the concept crystal clear, but focus directly on the “legal” side rather than explain first where the concept comes from or what it essentially is. This post provides illustrative examples, distinctions between ordinary donations and donations by reason of marriage, as well as its historical context.

Leave a CommentFrom the get go, I am a man of many interests. My description says it all. With that comes a lot of opportunities for expansion and growth, and generally that is a good thing. However, there are times when one must focus on the essentials to reach what must be reached — to get to where one wants to go — and excellently, if I may add.

Comments closedThe Hernandez versus Placer Dome case, as an illustrative example of the application of the Writ of Kalikasan, fails to elucidate. First of all, it strictly limits itself to the procedural aspects of the case. Second, it hides the factors that would have made sense of the technical exchanges between the parties. This post tries to supply the lacuna with with life-giving factual antecedents that may help understand the case.

Leave a CommentIn general, the essential parts of a good decision consist of the following: (1) statement of the case; (2) statement of facts; (3) issues or assignment of errors; (4) court ruling, in which each issue is, as a rule, separately considered and resolved; and, finally, (5) dispositive portion. The ponente may also opt to include an introduction or a prologue as well as an epilogue, especially in cases in which controversial or novel issues are involved.

And so the plot thickens. Hands down, China is flexing its muscles in the South China Sea. It is gobbling-up maritime features left and right. Littoral states, friendly or not to them, are no longer turning a blind eye. Things are getting out of hand. And with the (1) intentional ramming and sinking of boats; (2) water cannon forays; (3) burning and looting of Chinese factories in Vietnam; (4) killing of Chinese nationals also in Vietnam; (5) USA’s Asian Pivot; (6) incarceration of eleven Chinese poachers in Half Moon Bay by Philippine Maritime Forces; (7) brazen installation of an oil rig in the Paracels; (8) construction of an unsinkable aircraft carrier / airstrip in the Mabini reef; (9) continued air and sea stand-off in the Senkaku/Diayou island chain; (10) harassment of Philippine troops stationed at the Ayungin shoal; (11) abduction of two Chinese nationals in Sabah, Malaysia, allegedly by the Abu Sayaff; (12) and China’s bellicose statements in its state-run media, a global war is not far off.

Computers, like any digital device, have clocks in them. Aside from telling users the time, they also provide a sequencing mechanism for internal core functions and digital circuitry. However, sometimes these clocks malfunction. It might be because of a bad CMOS battery or a timezone mix-up. Fortunately, CentOS, or any Linux box for that matter, have a tool that synchronizes its clocks with central servers.
The Network Time Protocol (NTP) is such a tool. It functions as an initial configuration setter and auto updater for Linux or CentOS boxes.

Comments closedBy far, Linux (Centos) is the most robust server system that any decent IT guy can ask for. It is secure and very flexible. In the server management world, its vast user base can attest to its quality. However, Linux installation and configuration is not without challenges. But all tips and workarounds are on the Internet, so the problem is not a function of difficulty, but time.

For quite some time now, I have kept my silence on the West Philippine Sea (WPS) dispute. It’s not that I have lost interest or have have adopted a defeatist perspective but it’s just that I am too infoxiated by it. Apparently, any issue, no matter how relevant, loses its “bite” when one is inundated by it. At first, I thought I can train my mind and body to endure processing 200-300 news feeds for a few hours everyday. I did. However, after a couple of months, the topic lost its flavor and I sank into a writing stupor.
