Este mindsetul ăsta. </p><p><br /></p><p>Iar asta generează comportamente deviante, mână în mână cu sărăcia, lipsa de educație și faptul că nu există costuri administrative serioase. Nu tăiat de mâini ca la arabi , sau știu eu ce. Bani, că banii ne dor, supraveghere mai atentă, fie și automată ( dar în România au anulat prin lege , excepție de constituționalitate ceva , posibilitatea de a avea camere de viteză - in felul defect în care fuseseră implementate ) și decăderea din drepturi până la dovada îndreptării si reeducării. În loc de șpagă, de exemplu. </p><p><br /></p><p>Iar comportamentele deviante sunt de tipul - te trezești cu oameni care văd ( cred eu că văd, ar putea fi total retardați) că nu au unde să depășească , că o să intre frontal în tine și totuși se bagă a la chicken game, că o să frânezi tu , pariind in primul rând pe faptul că ești atent la ce fac ei. Oameni care se aruncă în depășiri fără niciun fel de vizibilitate pariind viața lor și pe a ta pe norocul de a nu se întâmplă nimic. Oameni care intra pe interzis și dacă te întâlnești cu ei manifestă tupeu să te dea pe tine la o parte dacă se poate. Astea nu-s pentru că n-au autostrăzi și pentru că sunt camioanele lente, ci pentru că sunt săraci, needucați, probabil trăiesc rău / greu și pun un preț foarte mic pe viața lor, anume trăiesc ca și când nu ar avea nimic de pierdut. Cei mai mulți au, de fapt, dar e un mindset Românesc - ține de competitivitate și sălbăticie, să te prefaci că nu ai nimic de pierdut, până pierzi. Și după aia te vaiți și cauți vinovați - sistemul, drumurile, normal. </p><p><br /></p><p>Și eu circul tot în România, tot pe drumurile ălea, tot cu oamenii ăia , și pe mine mă deranjează , evident aglomerația și statul pe loc și cu toate astea, am trecut prin și de nivelul ăla unde comportamentul meu trebuie scuzat de lipsa infrastructurii și în general ceilalți.

(The kernel does actually decompress it first. CPIO is used, because it is simple and robust to implement, requires not too much code, and has all the features needed.)</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">You can extract an initrd image into current directory using</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><div style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px; margin: 5px 20px 20px;"><div class="smallfont" style="font-size: 11px; margin-bottom: 2px;">Code:</div><pre class="bbcodeblock" dir="ltr" style="background-color: #cfd9ff; border: 1px inset; height: 34px; margin-bottom: 0px; margin-right: -99999px; margin-top: 0px; overflow: auto; padding: 3px; width: 1400.41px;">zcat <i>/boot/initrd...</i> | cpio -i</pre></div><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">You can generate an image from the contents of the current directory and all subdirectories using</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><div style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px; margin: 5px 20px 20px;"><div class="smallfont" style="font-size: 11px; margin-bottom: 2px;">Code:</div><pre class="bbcodeblock" dir="ltr" style="background-color: #cfd9ff; border: 1px inset; height: 34px; margin-bottom: 0px; margin-right: -99999px; margin-top: 0px; overflow: auto; padding: 3px; width: 1400.41px;">find . | cpio -o | gzip -c > <i>/tmp/new-initrd</i></pre></div><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">The image must be somewhere other than the current directory or any subdirectories, because otherwise cpio may include a partial copy of itself.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">An initrd image will contain a script (or program) called</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /init </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">(I keep the / in front to highlight that it will be in the root directory of the initrd image). That is the only real process the Linux kernel will start, whether an initrd is used or not. It will be process ID 1. If the process ever exits or crashes, kernel will panic -- but it is so rare you are unlikely to ever see that happen. (Okay, the kernel can start [worker processes], and even run</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /sbin/modprobe </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">to load modules to satisfy module dependencies, I think, but they don't count. They're just slaves working on specific tasks.)</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;">/init </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">is almost always a POSIX shell script, so feel free to extract an image and read it in your favourite text editor. (An initrd</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /init </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">will later on</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> exec </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">(replace itself) with the normal init, used during normal operation.

Then,</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /init </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">will parse the kernel command line,</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /proc/cmdline</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">. This is the string you can set in the boot loader, defining how you want to start up your system.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">It can then check files and directories in</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /proc</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">,</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /sys</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">, and</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /dev</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;"> to find out which hardware is present and load the appropriate modules, but we have something much better: udev. udev is a hotplug mechanism, where the kernel tells the userspace udev daemon about all the hardware it finds, and about all hardware events later on, like when you plug in or remove something. udev configuration is ordered as rules, usually in</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /lib/udev/rules.d/</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">, and it takes care of not only loading the necessary kernel modules, but also creating the necessary symlinks and all that.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">It is quite possible to have a DHCP client in an initrd, and use for example NFS for all other filesystems. It is often used for thin clients. The kernel command line may then contain the NFS server name and the name for the machine itself, so it can obtain the correct filesystems. As you can see, that requires only a little thought, and a rather simple initrd, to set up and maintain. (Of course, something like this is impossible with most common proprietary operating systems.)</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">In Linux, resuming from a suspend-to-disk image (usually called "hibernation") is also done in the initrd. If the initrd detects a suspended image, it will resume it instead of continuing with the normal boot. In fact, there is even an utility called kexec, which can start another kernel altogether, without a full reboot (a "warm reboot").</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">initrd is, for all intents and purposes, a very small operating system image. It has the singular purpose of preparing the system for the actual operating system you want to use. Typically, it will mount the true root filesystem (named in the kernel command line) -- it must contain basic binaries (</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;">/bin </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">and</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /sbin</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">), libraries (</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;">/lib </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">and possibly</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /lib64</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">), and of course configuration files (</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;">/etc</span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">). Finally, the</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /init </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">will replace itself with</span><span style="background-color: #e6e6e6; font-family: Monospace; font-size: 13.3333px;"> /sbin/init </span><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">on the actual system, which will continue with mounting the rest of the filesystems, and starting all the services.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">Many distros do require an initrd image, even if your kernel has everything built in, and does not support modules at all. In those cases, the initrd is expected to handle all of the other stuff mentioned above -- for example, starting udev, or looking for a hibernation image.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">On other distros, an initrd is not needed, and the init scripts can handle the boot from raw kernel (plus root filesystem) up. For example, you can look at Linux From Scratch to see what those init scripts then have to handle.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;">The Linux kernel really does not care whether you have an initrd, or if your root filesystem can handle the entire init by itself. It is more of a matter of versatility and ease of management; most distributions have automatic scripts which regenerate initrds when new kernels are installed. If you use Busybox, you can pack a quite usable system into an initrd and be done with it -- many routers actually do that, with the initrd stored on a built-in flash chip.</span><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><br style="background-color: #e6e6e6; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 13.3333px;" /><span style="font-family: Verdana, Arial, Helvetica, sans-serif;"><span style="background-color: #e6e6e6; font-size: 13.3333px;">https://www.linuxquestions.org/questions/linux-server-73/difference-between-initrd-and-vmlinuz-images-892868/</span></span>Alexandru Garbiahttp://www.blogger.com/profile/11848517291946594722noreply@blogger.com0tag:blogger.com,1999:blog-3323384667514365857.post-85704652021917548032024-01-25T03:59:00.000-08:002024-01-25T03:59:19.387-08:00query scale-out<p> <i><strong>Query scale-out</strong> is a feature in Power BI Premium that allows you to distribute query processing across multiple read-only replicas of a dataset. <u>This can significantly improve the performance of your reports,</u> <u>especially when you have a large number of users or when your dataset is very complex.</u></i></p><span class="ui-provider cuq cur bgk cus cut cuu cuv cuw cux cuy cuz cva cvb cvc cvd cve cvf cvg cvh cvi cvj cvk cvl cvm cvn cvo cvp cvq cvr cvs cvt cvu cvv cvw cvx" dir="ltr"><p style="margin-bottom: 16px; margin-top: 16px;"><i><strong>Here are some of the benefits of using query scale-out:</strong></i></p><ul><li style="margin-bottom: 8px;"><i><strong>Reduced query latency:</strong> When multiple users are querying a dataset, the replicas can share the load, which can significantly reduce the latency of each query.</i></li><li style="margin-bottom: 8px;"><i><strong>Increased throughput: </strong>With more replicas, you can handle more queries at the same time, which can improve the overall throughput of your Power BI solution.</i></li><li style="margin-bottom: 8px;"><i><strong>Improved data freshness: </strong>Refresh isolation ensures that data refresh operations do not impact query performance, so users can always see up-to-date data.</i></li><li style="margin-bottom: 8px;"><i><strong>Automated scaling: </strong>Power BI Premium can automatically scale the number of replicas based on usage, so you don't have to worry about manually adding or removing replicas.</i></li></ul><p style="margin-bottom: 16px; margin-top: 16px;"><i>Here are some of the limitations of using query scale-out:</i></p><ul><li style="margin-bottom: 8px;"><i><strong>Increased storage requirements: </strong>Each replica of a dataset needs to store the entire dataset, so you will need to have enough storage space to accommodate the replicas.</i></li><li style="margin-bottom: 8px;"><i><strong>Increased network traffic: </strong>When users query a dataset, the request must be sent to all of the replicas, so there may be an increase in network traffic.</i></li><li style="margin-bottom: 8px;"><i><strong>Potential for conflicts: </strong>If multiple replicas are updating the dataset at the same time, there is a potential for conflicts.

In imagine, valoarea de compensare este de 1.16, la un injector uzat existand mereu osclatii</span></p>Alexandru Garbiahttp://www.blogger.com/profile/11848517291946594722noreply@blogger.com0tag:blogger.com,1999:blog-3323384667514365857.post-34811569397174864212023-11-27T02:52:00.000-08:002023-11-27T02:52:39.249-08:00RDBMS history - genealogy<p> <a href="https://hpi.de/fileadmin/user_upload/fachgebiete/naumann/projekte/RDBMSGenealogy/RDBMS_Genealogy_V6.jpg">RDBMS_Genealogy_V6.jpg (2384×1684) (hpi.de)</a></p>Alexandru Garbiahttp://www.blogger.com/profile/11848517291946594722noreply@blogger.com0tag:blogger.com,1999:blog-3323384667514365857.post-87427854398171199762023-11-26T23:50:00.000-08:002023-11-27T00:00:14.158-08:00how to change gearbox oil getrag edc Renault dw6 - 6 speed wet clutches - 6DCT450<p> <a href="https://www.youtube.com/watch?v=-GtV0yTlBhc">(3) RENAULT | Oil Change Guide in Automatic Transmission DW6 - EDC 6 Speeds - YouTube</a></p><p>5.7 liters are needed </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjv4UIi8fl6lMD-pujC5PUPWWAlSatTZ8UlSj18cogqjupXSiWkuKdu1U8EUZ3VGSvr9PJbpD0wyHS9HHojD3HMlCd5-dRmrOlRvAViioJhdnl8E8_H7-u6Aw77p3oO43-O4eye84H28x3cwG8-gdHYRdJRk2pMgewCjkayBolCZkUjWhUNmvK1vYGlN70w" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="636" data-original-width="1209" height="168" src="https://blogger.googleusercontent.com/img/a/AVvXsEjv4UIi8fl6lMD-pujC5PUPWWAlSatTZ8UlSj18cogqjupXSiWkuKdu1U8EUZ3VGSvr9PJbpD0wyHS9HHojD3HMlCd5-dRmrOlRvAViioJhdnl8E8_H7-u6Aw77p3oO43-O4eye84H28x3cwG8-gdHYRdJRk2pMgewCjkayBolCZkUjWhUNmvK1vYGlN70w" width="320" /></a></div><br /><br /><p></p>Alexandru Garbiahttp://www.blogger.com/profile/11848517291946594722noreply@blogger.com0tag:blogger.com,1999:blog-3323384667514365857.post-88030615631961677662023-11-26T23:27:00.000-08:002023-11-26T23:30:33.039-08:00why do Renault espace with edc gearbox 1.6 diesel 160 horse power - fails<p> <a href="https://www.youtube.com/watch?v=1mjqT9EGukM&t=479s">(3) problème mélange d'eau et huile de boite vitesse automatique DW6 sur renault espace 5 - YouTube</a></p><p>they mix coolant and gearbox oil, therefore the engine do not get enough coolant. </p><p><br /></p><p>gearbox dw6 oil(6 speed edc gearbox): 7711579456</p><p><br /></p><p>coolant anti freeze for renault espace 5: 7711428132 (glaceol rx type D)</p><p><br /></p><p><br /></p><p></p><div class="separator" style="clear: both; text-align: center;">Gearbox oil heat exchanger - oil cooler - 216058036R</div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgR3GCqyOjyKR6l4oZGkZk5pmrbsezdRkdrFOaG5M9iKLIG42ioRvscnhWGnBnuZcXlgWUFIJMh7QbrZiijWLpDxWspusMnj-fPsW_Y7H3Py7iDpQog14s1cCXQaNJdVEVfLBHCSRfMe1KibrX6WuH6BGlxdcD-bgHofTVf5OBKShNCAwmSvy-2uWjSRxfx" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="476" data-original-width="1414" height="108" src="https://blogger.googleusercontent.com/img/a/AVvXsEgR3GCqyOjyKR6l4oZGkZk5pmrbsezdRkdrFOaG5M9iKLIG42ioRvscnhWGnBnuZcXlgWUFIJMh7QbrZiijWLpDxWspusMnj-fPsW_Y7H3Py7iDpQog14s1cCXQaNJdVEVfLBHCSRfMe1KibrX6WuH6BGlxdcD-bgHofTVf5OBKShNCAwmSvy-2uWjSRxfx" width="320" /></a></div><br /><br /><p></p><p><span face="Roboto, sans-serif" style="background-color: white; color: #767676; font-size: 12px;">8266113119 ; </span><strong itemprop="name" style="background-color: white; color: rgba(0, 0, 0, 0.87); font-family: Roboto, sans-serif; font-size: 21px;">EC109003</strong><span color="rgba(0, 0, 0, 0.87)" face="Roboto, sans-serif" style="background-color: white; font-size: 21px;"> ; </span><span color="rgba(0, 0, 0, 0.87)" face="Roboto, sans-serif"><span style="font-size: 21px;">DU3R-3J389-DA ; </span></span><span face="Roboto, sans-serif" style="color: #ba0087;"><span style="font-size: 21px;">110-05336 ;</span></span></p>Alexandru Garbiahttp://www.blogger.com/profile/11848517291946594722noreply@blogger.com0tag:blogger.com,1999:blog-3323384667514365857.post-24035342636525888062023-11-24T23:23:00.000-08:002023-11-24T23:23:37.541-08:00Oana Gheorghiu<p> "<span style="background-color: white; color: #373a3c; font-family: "PT Serif", serif; font-size: 20px;">Oana este unul din oamenii aia care și-au asumat să construiască acolo unde alții au dărâmat timp de 30 de ani. „<i>Noi ne-am pierdut frica</i>. Și aș vrea ca toți oamenii din țara asta să-și piardă frica, pentru că<b> această frică ne ține încorsetați, ne face să nu reacționăm</b>, <b>ne face să nu luăm atitudine</b>… <b>E lucrul care ne ține cel mai mult pe loc</b>. Dacă nu am mai avea frică, dacă am putea să ne unim, dacă ne-am tempera orgoliile și am renunța la ego, dacă am vrea să ne asociem... am avea orașe mai faine, am avea spitale și școli mai bune, iar copiii noștri ar avea o altă perspectivă.

Omul îmbolnăvit de plaga occidentală devine unul neliniștit, căutând să sară peste etape în vederea scurtării căii spre „<b>realizare</b>”. Doar că realizarea pe care o caută omul îmbolnăvit de virusul occidentului nu este una către devenire, ci una de animal cu instincte strict de consum. Omul de acest tip se mișcă într-un cerc vicios. Pornește de la <b>frustarea generată de lipsa sa de sens pe care consideră că și-o poate „stinge” printr-o achiziție</b>. De aici rezultă dorința achiziționării unui produs nou(cu cât mai scump cu atât mai capabil - pe scara sa de valori - de a-i oferi o rezolvare mai eficientă a frustrării). Urmează efortul strângerii banilor - efort „ușurat” de societate prin facilități lejere de creditare - care se finalizează cu achiziția. Apoi vine un scurt moment de satisfacție care, aproape imediat e înlocuit de frustrarea lipsei de sens. Iar ciclul se reia. Aceasta este <b>roata mortală a ratării occidentale: frustrare -> dorință -> efort -> achiziție ->satisfacție -> frustrare</b>. Astfel, frustrarea omului fără sens ajunge motorul unei economii de care profită strict cei care-i înțeleg mecanismul, canalizând frustrarea lipsei de sens către un surogat precum consumul. </p>Alexandru Garbiahttp://www.blogger.com/profile/11848517291946594722noreply@blogger.com0
