Router Quotes

Sometimes we may wonder what we have gotten ourselves into. Unfamiliar or unexpected incidents throw us off balance. Although we have always been stable like rocks in the surf, we feel trapped by our vulnerability. The router of our personality has broken down and no longer emits or receives any signals. We have no interaction with the world. We realize, at that moment, that we are interdependent beings, and our individuality only exists through a cluster of interactions. (“The infinite Wisdom of Meditation“)

The real enemy of genius is the router in the hallway.

The frantic stupidity of Wall Street’s stock order routers and algorithms was simply an extension into the computer of the willful ignorance of its salespeople.

My computer set-up is crazy. I have wireless set up on my iMac, aimed at a router, which itself is perfectly angled at another router, which in turn is angled at a sofa covered in tinfoil to bounce the signal to the original source. If you want to sit on that couch, you’d better be wearing a reflective astronaut suit, or at least a spaghetti strainer on your head. It reminds me of something Zelda told me: “The only thing tinfoil should cover is a Kiss. But you wouldn’t know anything about kissing.

[Texting] discourages thoughtful discussion or any level of detail. And the addictive problems are compounded by texting's hyperimmediacy. E-mails take some time to work their way through the Internet, through switches and routers and servers, and they require that you take the step of explicitly opening them. Text messages magically appear on the screen of your phone and demand immediate attention from you. Add to that the social expectation that an unanswered text feels insulting to the sender, and you've got a recipe for addiction: You receive a text, and that activates your novelty centers. You respond and feel rewarded for having completed a task (even though that task was entirely unknown to you fifteen seconds earlier). Each of those delivers a shot of dopamine as your limbic system cries out "More! More! Give me more!

There were three people in my home and I was the only one showing Electromagnetic Hypersensitivity and reactivity to the radio frequency transmitting utility meters. For these reasons I did not shield my home and took the route of adapting my body to the toxic electromagnetic environment.

Improbable as it may be, the day still has a few indignities left. The day waters down indignity with frustration to make it last longer. Abomination, thy name is Subway. He cannot enter. They flood through turnstiles, hips banging rods, and will not let him enter. He must get home, but it's all he can do to get halfway in before another one charges at him. A fish out of school. Everybody knows how it works except for him. All of them from every floor are crammed into this one subway car: the makers of memos, the routers of memos, the indexers filers and shredders of memos, the always-at-their-desks and the never-around. How do they all fit. Squabbling like pigeons over stale crumbs of seats. Everyone thinks they are more deserving, everyone thinks their day has been harder than everyone else's, and everyone is correct.

Remember that a computer is for computing and routers for routing

Eating organic for good health and spending your day sitting down using a wireless computer that is next to a WiFi router is a classic case of Yin & Yang.

We have to assume Loving’s found your account. If you read messages or send any, it’s possible for him to correlate time with router and server traffic in the area here.

Just a maintenance tech here, folks, heading home after a long night of rebooting routers. That’s all. I am definitely not an indent making a daring escape with ten zettabytes of stolen company data in his pocket. Nosiree.

Under a $652-million clandestine program code named GENIE, the NSA, CIA, and special military operatives have planted covert digital bugs in tens of thousands of computers, routers, and firewalls around the world to conduct computer network exploitation, or CNE. Some are planted remotely, but others require physical access to install through so-called interdiction—the CIA or FBI intercepts shipments of hardware from manufacturers and retailers in order to plant malware in them or install doctored chips before they reach the customer.

IP is responsible for taking pieces of information and moving them through the various switches, routers, gateways, repeaters, and other devices that move information from one network to the next and all around the world. IP tries hard to deliver the data at the destination,

The label “jack-of-all-trades but master of none” is normally meant to be derogatory, implying that the labelee lacks the focus to really dive into a subject and master it. But, when your online shopping application is on the fritz and you’re losing orders by the hundreds as each hour passes, it’s the jack-of-all-trades who not only knows how the application’s code works but can also do low-level UNIX debugging of your web server processes, analyze your RDBMS’s configuration for potential performance bottlenecks, and check your network’s router configuration for hard-to-find problems. And, more important, after finding the problem, the jack-of-all-trades can quickly make architecture and design decisions, implement code fixes, and deploy a new fixed system to production. In this scenario, the manufacturing scenario seems quaint at best and critically flawed at worst.

Based on Tor, which is what they all use. Which was written by the United States Naval Research Laboratory, ironically. To provide a safe haven for political dissidents and whistleblowers, all around the world. Which is the law of unintended consequences, right there, biting the world in the ass. Tor stands for The Onion Router. Because that’s what we’re dealing with here. Layers upon layers upon layers, like the layers of an onion, in the Deep Web itself, and inside all of its separate sites.

forward to it, and Cooper, coatless and chilly in the desert evening, was thinking that the radio man was an asshole. He’d chased Vasquez for nine days now. Someone had warned the programmer just before Cooper got to the Boston walk-up, a brick rectangle where the only light had been a window onto an airshaft and the glowing red eyes of power indicators on computers and routers and surge protectors. The desk chair had been against the far wall as if someone had leaped out of it, and steam still rose from an abandoned bowl of ramen. Vasquez had run, and

PRISM enabled the NSA to routinely collect data from Microsoft, Yahoo!, Google, Facebook, Paltalk, YouTube, Skype, AOL, and Apple, including email, photos, video and audio chats, Web-browsing content, search engine queries, and all other data stored on their clouds, transforming the companies into witting coconspirators. Upstream collection, meanwhile, was arguably even more invasive. It enabled the routine capturing of data directly from private-sector Internet infrastructure—the switches and routers that shunt Internet traffic worldwide, via the satellites in orbit and the high-capacity fiber-optic cables that run under the ocean.

It’s hard to blame Representative Petri for missing the point. The value of studying fireflies is endlessly surprising. For example, before 1994, Internet engineers were vexed by spontaneous pulsations in the traffic between computers called routers, until they realized that the machines were behaving like fireflies, exchanging periodic messages that were inadvertently synchronizing them. Once the cause was identified, it became clear how to relieve the congestion. Electrical engineers devised a decentralized architecture for clocking computer circuits more efficiently, by mimicking the fireflies’ strategy for achieving synchrony at low cost and high reliability.

In an age of network tools, in other words, knowledge workers increasingly replace deep work with the shallow alternative—constantly sending and receiving e-mail messages like human network routers, with frequent breaks for quick hits of distraction. Larger efforts that would be well served by deep thinking, such as forming a new business strategy or writing an important grant application, get fragmented into distracted dashes that produce muted quality. To make matters worse for depth, there’s increasing evidence that this shift toward the shallow is not a choice that can be easily reversed. Spend enough time in a state of frenetic shallowness and you permanently reduce your capacity to perform deep work.

...'unless you convert to Orthodoxy, you too will follow your Pope down that valley, through the scorching fire. We will watch you from this balcony,' he added, 'but of course it will then be too late to save you.' I smiled, but Fr. Theophanes was in full swing and clearly in no mood for joking. 'No one can truly know what that day will be like.' He shook his head gravely. 'But some of our Orthodox fathers have had visions. Fire-fire that will never end, terrible, terrible fire - will come from the throne of Christ, just like it does on the icons. The saints-those who are to be saved, in router words the Orthodox Church-will fly in the air to meet Christ. But sinners and all non-Orthodox will be separated from the Elect. The damned will be pushed and prodded by devils down through the fire, down from the Valley of Joseph, past here-in fact exactly the route those Israeli hikers took today-down, down to the Mouth of Hell.' 'Is that nearby?' 'Certainly,' said Theophanes, stroking his beard. 'The Mouth of Hell will open up near the Dead Sea.' 'That is in the Bible?' 'Of course,' said Theophanes. 'Everything I am telling you is true.

Every problem is the result of a previous solution.

Among other devices, the agency intercepts and tampers with routers and servers manufactured by Cisco to direct large amounts of Internet traffic back to the NSA’s repositories.

default, HSRP does not reinstate the primary as the active router when it comes back online. To enable this behavior, you must configure the routers to preempt. This means that when a router with a higher priority than the active router comes online, the active router will allow the higher-priority router to become active.

If you email your friend a document to print, the information may get copied in rapid succession from magnetizations on your hard drive to electric charges in your computer’s working memory, radio waves in your wireless network, voltages in your router, laser pulses in an optical fiber and, finally, molecules on a piece of paper. In other words, information can take on a life of its own, independent of its physical substrate!

Second, install accountability software on your computer and phone. This software is inexpensive, is available from many different sources, and either blocks objectionable websites or records your Internet activity and sends it to someone of your choosing. It’s best to use software that does both. You also should implement filtering and monitoring strategies for your router—not just for your individual devices.

However, despite the enormous digital territory and huge number of Internet users, only a few users of what is called the “Surface Web” are aware of or actively observe what goes on in quite a different layer of the Internet. The data stored in another layer are not accessible to the majority of users. This is called “The Deep Web,” which is data traffic not picked up by the algorithms of search engines. Then, there is the “Dark Web,” where sites are intentionally encrypted and usually accessed by someone knowledgeable about how to find and get onto such sites. Typically, these sites are engaging in forbidden activities ranging from drug sales to weapons or hitman transactions. In order to see the sites on the “Dark Web,” a user must have a specialized browser like Tor, The Onion Router.

people in now. Time to hustle for charity.” We all look toward the ropes, where my winger Castro is beckoning to Rebecca. “Look who’s here!” he calls. “No way!” another player shouts. “Becca! We missed you!” Rebecca hesitates. “Do you mind if I say hello?” “Go,” I tell her. Stay, my heart whines. “I’m not going to pick his pocket on the router division in the next two minutes,” Alex says with a grumble. “Even I can’t work that fast.” Becca gives me a glance of amusement and then hurries off to greet her friends. I watch her walk away, her smooth heels against the grass… “Hey,” Alex says, snapping her fingers. “Romeo.” This startles me out of my stupor. “What?” Alex smirks at me. Then she takes my drink out of my hand and takes a tiny sip. “I swear to God, Nate. Does that girl know how you feel?” Shit. Alex snickers at my expression. “Seriously? I hope you weren’t actually trying to keep it a secret. Your poker face sucks.” “I don’t often lose at poker.” World’s lamest comeback.

Your Kindle will recognize Wi-Fi networks with a WPS compatible router. To connect via WPS, from your Kindle select the wireless network you want to use. Next, press the WPS button on your router, and then select the WPS button on your Kindle during the Wi-Fi setup process. Once you have successfully connected to a network, the Wi-Fi status indicator will display the network's signal strength.

Another game-changing project is the BRCK, pronounced “brick,” created by the same team behind Ushahidi and iHub. On a flight back to Africa from the United States some years ago, Hersman looked down on our vast, rugged continent and wondered why it was that most routers and modems were built for the first-world comfort zones of, say, New York or London, whereas most Internet users actually live in the harsh, far less comfortable environments of Asia, Africa and Latin America. The team sketched out a design for a rugged portable connectivity device that could work in remote conditions where electrical power and Internet connections were a problem. The result is the BRCK, a sturdy, brick-shaped, cloud-enabled Wi-Fi hotspot router from which you can access the Internet from anywhere on the continent that is close to a signal. It has an antenna, charger, USB ports, 4 GB of storage, a built-in global SIM card and enough backup power to survive a blackout. The device sells for $199 online and is already being used in 45 countries around the world. Consider the provenance: designed in Nairobi, Kenya; manufactured in Austin, Texas. This is a complete reversal of the standard manufacturing paradigm. Again, an example of African technology going global.

When I realized that my home was completely filled with a biologically toxic radio wave field, I decided that the best route forward was to milk the home for all of the biological research that I could possibly produce from it!

For years, the US government loudly warned the world that Chinese routers and other Internet devices pose a “threat” because they are built with backdoor surveillance functionality that gives the Chinese government the ability to spy on anyone using them. Yet what the NSA’s documents show is that Americans have been engaged in precisely the activity that the United States accused the Chinese of doing.

The NSA routinely receives—or intercepts—routers, servers, and other computer network devices being exported from the United States before they are delivered to the international customers. The agency then implants backdoor surveillance tools, repackages the devices with a factory seal, and sends them on.

I felt a stir of hope. Computers and smartphones left a number trail as distinct as tracks in the snow each time they touched the Internet. One of these numbers was assigned by providers but one was hardwired into the device. From the instant a person signed on, their computer’s numerical path was logged and recorded by Internet service providers, networks, wireless hotspots, servers, and routers, forever linking the time, location, and path of service to your specific machine. Surf the Net, check your email, chat with a friend—each new router and service provider recorded and stored your numbers. The geolocation of a computer could be found by back-tracing this trail of numbers. Finding an approximate location was relatively easy. The spooks Jon knew could probably back-trace to a specific sign-on address, identify a specific machine, and pull the name of the person who bought it from the manufacturer. I

Hot Standby Router Protocol (HSRP) is a Cisco-proprietary First Hop Redundancy Protocol (FHRP). HSRP

OSPF’s backbone area is Area 0, and every other area we create must contain a router that has a physical or logical interface in Area 0.

This device combines multiple features into a single hardware device. These features often include those of an AP, firewall, router, and Dynamic Host Configuration Protocol (DHCP) server, along with other features. Strictly speaking, these devices are residential WLAN gateways as they are the entry point from the Internet into the wireless network. However, most vendors instead choose to label their products as wireless broadband routers or simply wireless routers. Due

It’s important for you to understand that routers, which work at the Network layer, don’t care about where a particular host is located. They’re only concerned about where networks are located and the best way to reach them—including remote ones. Routers are totally obsessive when it comes to networks. And for once, this obsession is a good thing! The Data Link layer is responsible for the unique identification of each device that resides on a local network.

Terrorism suspects aren’t the NSA’s only targets, however. Operations against nation-state adversaries have exploded in recent years as well. In 2011, the NSA mounted 231 offensive cyber operations against other countries, according to the documents, three-fourths of which focused on “top-priority” targets like Iran, Russia, China, and North Korea. Under a $652-million clandestine program code named GENIE, the NSA, CIA, and special military operatives have planted covert digital bugs in tens of thousands of computers, routers, and firewalls around the world to conduct computer network exploitation, or CNE. Some are planted remotely, but others require physical access to install through so-called interdiction—the CIA or FBI intercepts shipments of hardware from manufacturers and retailers in order to plant malware in them or install doctored chips before they reach the customer.

Just like Nova Compute, which lets you virtualize machine instances, Neutron Networking lets you virtualize networking components such as routers, firewalls, and load balancers, as shown in Figure 2-10

In Neutron, when creating a router you can additionally specify that it provide high availability (HA), or that it be a distributed virtual router, which as mentioned above is spread out across all of the compute nodes

Network connectivity Books, magazines, and other materials are delivered directly to your Kindle via its built-in network connectivity. If your Kindle offers both Wi-Fi and 3G connectivity, use Wi-Fi whenever possible for faster downloads. You can connect to a Wi-Fi network at home or at hotspots around the world. To view available Wi-Fi networks, tap the Menu button and select Settings. On the Settings page, select Wi-Fi Networks and the name of the network you want to use. If you see a lock symbol next to the network name, it requires a password. Tap the Rescan button to recheck for available Wi-Fi networks. Please note that your Kindle does not support connecting to ad hoc (or peer-to-peer) Wi-Fi networks. Your Kindle will recognize Wi-Fi networks with a WPS compatible router. To connect via WPS, from your Kindle select the wireless network you want to use. Next, press the WPS button on your router, then select the WPS button on your Kindle during the Wi-Fi setup process. Once you have successfully connected to a network, the Wi-Fi status indicator will display the network's signal strength. Kindle Paperwhite 3G models use the same technology as cell phones, so they are dependent on cellular coverage areas. By default, a 3G device will automatically connect to a 3G network. If there isn't sufficient 3G signal strength, it will connect to a slower GPRS or EDGE network. Your Kindle automatically turns off 3G when you connect using Wi-Fi. If you disconnect from a Wi-Fi network or move out of Wi-Fi range, your Kindle will automatically switch back to 3G. To turn wireless off, tap the Menu button and select Settings, then toggle Airplane Mode on. Any periodical downloads or other pending updates that require a wireless connection will occur the next time you turn it back on. Turning on Airplane Mode disables both 3G and Wi-Fi connections.

while American companies were being warned away from supposedly untrustworthy Chinese routers, foreign organizations would have been well advised to beware of American-made ones. A June 2010 report from the head of the NSA’s Access and Target Development department is shockingly explicit. The NSA routinely receives—or intercepts—routers, servers, and other computer network devices being exported from the United States before they are delivered to the international customers. The agency then implants backdoor surveillance tools, repackages the devices with a factory seal, and sends them on. The NSA thus gains access to entire networks and all their users. The document gleefully observes that some “SIGINT tradecraft … is very hands-on (literally!)”:

Shallow Work: Noncognitively demanding, logistical-style tasks, often performed while distracted. These efforts tend to not create much new value in the world and are easy to replicate. In an age of network tools, in other words, knowledge workers increasingly replace deep work with the shallow alternative—constantly sending and receiving e-mail messages like human network routers, with frequent breaks for quick hits of distraction. Larger efforts that would be well served by deep thinking, such as forming a new business strategy or writing an important grant application, get fragmented into distracted dashes that produce muted quality.

Sending Messages in Real Time to Current Users Cisco IOS running on a device at least tries to allow current users to see log messages when they happen. Not every router or switch may have users connected, but if some user is logged in, the router or switch benefits by making the network engineer aware of any issues. By default, IOS shows log messages to console users for all severity levels of messages. That default happens because of the default logging console global configuration command. In fact, if you have been using a console port throughout your time reading this book, you likely have already noticed many syslog messages, like messages about interfaces coming up or going down. For other users (that is, Telnet and SSH users), the device requires a two-step process before the user sees the messages. First, IOS has another global configuration setting—logging monitor—that tells IOS to enable the

Figure 33-1 summarizes these key points about how IOS on a Cisco router or switch processes log messages for currently connected users. In the figure, user A sits at the console, and always receives log messages. On the right, the fact that user B sees messages (because user B issued the terminal monitor command after login), and user C does not, shows that each user can control whether or not she receives log messages.

Storing Log Messages for Later Review With logging to the console and to terminals, an event happens, IOS sends the messages to the console and terminal sessions, and then IOS can discard the message. However, clearly, it would be useful to keep a copy of the log messages for later review, so IOS provides two primary means to keep a copy. IOS can store copies of the log messages in RAM by virtue of the logging buffered global configuration command. Then any user can come back later and see the old log messages by using the show logging EXEC command. As a second option—an option used frequently in production networks—all devices store their log messages centrally to a syslog server. RFC 5424 defines the Syslog protocol, which provides the means by which a device like a switch or router can use a UDP protocol to send messages to a syslog server for storage. All devices can send their log messages to the server. Later, a user can connect to the server (typically with a graphical user

All devices can send their log messages to the server. Later, a user can connect to the server (typically with a graphical user interface) and browse the log messages from various devices. To configure a router or switch to send log messages to a syslog server, add the logging {address|hostname} global command, referencing the IP address or hostname of the syslog server. Figure 33-2 shows the ideas behind the buffered logging and syslog logging.

Configuring and Verifying System Logging With the information in Table 33-2, configuring syslog in a Cisco IOS router or switch should be relatively straightforward. Example 33-2 shows a sample, based on Figure 33-4. The figure shows a syslog server at IP address 172.16.3.9. Both switches and both routers will use the same configuration shown in Example 33-2, although the example shows the configuration process on a single device, Router R1.

Problem Isolation Using the ping Command Someone sends you an email or text, or a phone message, asking you to look into a user’s network problem. You Secure Shell (SSH) to a router and issue a ping command that works. What does that result rule out as a possible reason for the problem? What does it rule in as still being a possible root cause? Then you issue another ping to another address, and this time the ping fails. Again, what does the failure of that ping command tell you? What parts of IPv4 routing may still be a problem, and what parts do you now know are not a problem? The ping command gives us one of the most common network troubleshooting tools. When the ping command succeeds, it confirms many individual parts of how IP routing works, ruling out some possible causes of the current problem. When a ping command fails, it often helps narrow down where in the internetwork the

172.16.1.51 and vice versa. You can reasonably assume that the switches learned the MAC addresses of the router and the host, adding those to the MAC address tables. Host A and Router R1 completed the ARP process and list each other in their respective Address Resolution Protocol (ARP) tables. The failure of a ping, even with two devices on the same subnet, can point to a variety of problems, like those mentioned in this list.

First, to understand why the standard and extended ping results have different effects, consider first the standard ping 172.16.1.51 command on R1, as shown previously in Figure 23-7. As a standard ping command, R1 used its LAN interface IP address (172.16.1.1) as the source of the ICMP Echo. So, when the host (A) sent back its ICMP echo reply, host A considered the destination of 172.16.1.1 as being on the same subnet. Host A’s ICMP echo reply message, sent back to 172.16.1.1, would work even if host A did not have a default router setting at all! In comparison, Figure 23-8 shows the difference when using an extended ping on Router R1. An extended ping from local Router R1, using R1’s S0/0/0 IP address of 172.16.4.1 as the source of the ICMP echo request, means that host A’s ICMP echo reply will flow to an address in another subnet, which makes host A use its default router setting.

The comparison between the previous two figures shows one of the most classic mistakes when troubleshooting networks. Sometimes, the temptation is to connect to a router and ping the host on the attached LAN, and it works. So, the engineer moves on, thinking that the network layer issues between the router and host work fine, when the problem still exists with the host’s default router setting.

Implementing NTP Clients, Servers, and Client/Server Mode With NTP, servers supply information about the time of day to clients, and clients react by adjusting their clocks to match. The process requires repeated small adjustments over time to maintain that synchronization. The configuration itself can be simple (to the extent covered in this book), or it can be extensive once you add security configuration and redundancy. As an example, just to show the basic syntax and show commands, consider Figure 33-5. It has three routers, all of which will use NTP. R1 will act as an NTP client, R3 as an NTP server, but R2 will be in client/server mode.

The configuration in Example 33-8 works, but in many cases, routers might have multiple ntp server commands configured for redundancy. The goal is to have at least one usable clock source (servers per multiple ntp server commands, or internal clock as per the ntp master command). The router then chooses the best NTP clock source based on the stratum level. The stratum level defines the quality of the clock source; the lower the stratum, the better the source.

For instance, consider the topology in Figure 33-6, with Router R4 on the right acting as NTP server and the other routers acting as clients. R4 has three IP addresses that the clients could put in their ntp server address commands. Now consider what happens when one interface on R4 fails, but only one. No matter which of the three interfaces fails, that IP address on that interface cannot be used to send and receive packets. In that case, for any NTP clients that had referred to that specific IP address There would likely still be a route to reach R4 itself. The NTP client would not be able to send packets to the configured address because that interface is down.

Analyzing Topology Using CDP and LLDP The first two major sections of this chapter showed two features—Syslog and NTP—that work the same way on both routers and switches. This final section shows yet another feature common to both routers and switches, with two similar protocols: the Cisco Discovery Protocol (CDP) and the Link Layer Discovery Protocol (LLDP). This section focuses on CDP, followed by LLDP.

Examining Information Learned by CDP CDP discovers basic information about neighboring routers and switches without needing to know the passwords for the neighboring devices. To discover information, routers and switches send CDP messages out each of their interfaces. The messages essentially announce information about the device that sent the CDP message. Devices that support CDP learn information about others by listening for the advertisements sent by other devices.

Ways to Make use of a Router This article demonstrates how to use a router securely as well as uses some tips to stay secure as well as generate a top quality item of work. When utilizing a router, or any power device, always work out risk-free practices. It is necessary to keep in mind that routers are effective tools as well as could be harmful. When utilizing a router, always stay concentrated on just what you are doing, as well as regard the tool being used. safety and security standards: Constantly utilize a sharp router bit. Plain router bits can not only affect the quality of the work surface but could additionally be really unsafe. Plain router bits put much more stress and anxiety on the router and typically end up melting the wood. Utilizing boring router little bits could also catch the timber as well as trigger the router to bent from your hands. Constantly see to it the work is secured down firmly. Wood secures made particularly for this can be bought. Feed the router from delegated right to ensure that the reducing side meets the timber first. Use superficial passes, going deeper right into the timber with each pass. making to deep of a pass can burn the timber, or perhaps cause the router to twist out of one's hands. Do not ever before push the router. enable the router to relocate through the wood a lot more slowly. feeding the router also quickly could trigger the timber to burn, splinter, or chip. Tips and Tricks Fasten a piece of wood the exact same density of the workpiece to the router table or bench so that it could work as a support for the router. This will prevent the router from wobbling while you make it. Utilize an edge guide whenever feasible. Look for knots warps and nails in the timber you are transmitting. Never ever utilize a router on damp timber. There are various techniques that can be attempted when utilizing a router. Various techniques might work better for various types of router little bits being used as well as various kinds of wanted cuts. Edge Profiles: When transmitting side accounts make certain your workpiece is clamped down safely by using a timber clamp. Relocate the router in a counter-clockwise motion around the beyond the work surface. When cutting the inside of an item, reduced clockwise. (You need to also cut clockwise around the top right corner of the item as well as the lower left corner of the item and afterwards walk around the whole piece counter-clockwise. This will stop splintering at the corners.). Make shallow passes with the Side Bit, going deeper with each pass. It might be a good idea to test the router on an item of scrap wood to see simply how shallow making each pass. Different timbers could chip much easier, and for certain items you may have to take even more shallow passes compared to others. * Remember that when reducing a piece with an edge trim bit, the item needs to be sanded prior to directing. Dado Cuts:. Dado cuts make grooves in timber. Dado cuts could be made in wood utilizing a router with a straight router little bit and a router jig or a t-square. Pick straight router bits that will produce the desired groove size. Test the router bit by using the router on a scrap piece of wood to guarantee it will certainly make the preferred cut. Then secure the t-square to the work piece and also make the wanted cuts. Route on the appropriate side of the t-square or jig so that the router presses against the firmly secured jig rather than away from it. This will certainly make certain straight also dado cuts.

This wasn’t literature; it was narcissism sluiced through an internet router to generate social-media-trendy verbal automatisms (“I felt seen,” “the struggle is real”) classed up with pseudoacademic jargon (“discourse,” several more instances of “toxic masculinity,” anything with “spaces”) that disburdened both writer and reader from having to think through the idea at hand. And he would be enabling their intellectual laziness by feeding them this processed, preservative-laden junk.

satellite dish. It was an inexpensive Internet camera that included audio, and was connected to the building’s wireless network and served any tenant who wished to join it. It also served somebody else. It served Mike Morales, and not in the way everybody thought, which was why it hadn’t occurred to Lucy to check. And she was furious with herself. Since it was known that another device was connected to the network—the camera that Morales said he had installed himself—it hadn’t entered Lucy’s mind to access the log to the wireless router. It hadn’t occurred to her she ought to check the router’s admin page. Had she done that last night, she would have discovered what she now knew, and she tried Marino again. For the past half-hour, she’d tried him and Berger, and had gotten voicemail. She didn’t leave a message. She wasn’t about to leave a message the likes of the one she had. This time Marino answered, thank God. “It’s me,” she said. “You in a wind tunnel, or what?” he said.

On June 4, a secret cable from the American embassy in Estonia reported an epochal event with an eye-popping headline: “WORLD’S FIRST VIRTUAL ATTACK AGAINST NATION STATE.” “Estonia has been the victim of the world’s first coordinated cyberattacks against a nation state and its political and economic infrastructure,” the embassy report began. “For over a month, government, banking, media, and other Estonian websites, servers, and routers came under a barrage of cyberattacks.… Experts cite the nature and sophistication of the attacks as proof of Russian government complicity

The thing is, your unconscious mind is smart. There’s usually a reason when absolutely nothing at all comes up; having absolutely no feelings, thoughts or sensations is actually a very unusual state. Your mind has to try hard to make that happen. So, if it keeps happening, this might suggest that controlled precognition is not for you, not right now at least. Your unconscious mind, particularly your superconscious or what we call your “higher self”, might know that getting involved in controlled precognition would be destabilizing for you. Likely because you would learn about parts of yourself that are not great for you to access without some kind of safe help. So maybe it’s saying “no” in the way it knows how to do that. This is fine, and you should listen. If you still want to pursue controlled precognition, seek a mental health professional that you trust and start exploring what might be hiding in your subconscious. Odds are, once your unconscious mind feels like controlled precognition is safe for you, you’ll come back to it and it will be much better for you and less destabilizing than it would have been before seeking help. Usually, however, the problem is the reverse: so many seemingly random images, thoughts and sensations come up that people feel overwhelmed and end up with garbage in their controlled precognition sessions. That’s why the six-step controlled precognition protocol was created, so you can learn to carefully perform controlled precognition, learning to weed out the fantasy thoughts and concentrate on those impressions that are delivered to you without further elaboration by story telling. What if I don’t remember any of my dreams? That can happen for many reasons. One is that you might have had a traumatic experience, and you might not be ready to re-live it in your dreams. If this is the case, I would say don’t worry about remembering your dreams. You can use controlled precognition to sense the future, and if you want to work with a mental health professional to work through the trauma to make it safe to remember your dreams, then you can do that independently. If you’re sure you want to remember your dreams, here’s a list of things to try. When we’re lucky, life is long … try them all! • Write down your dreams every morning, and when you don’t have any, write down, “I don’t remember my dreams right now, but I might later. And if I do, I’ll record them.” That gets you in the daily habit, and it sets an intention that tells your subconscious that you’re ready to start remembering dreams. • Make sure you get enough vitamin B-6, found in eggs, nuts, vegetables, wholegrains and milk, as it seems to enhance dream clarity as compared to a placebo. • Try to go to bed at a time that feels good to you. • Turn off wi-fi at night in your house, if you have a router. • Don’t look at any screens within one hour of going to bed.

More IT people crawl beneath the long table, unhooking cables and routers and throwing them into a rat’s nest of gear.

Every single smartphone in India with a Chinese chip is now listening and broadcasting to us. Every single telephone network with a Chinese switch or router is now a listening post of the PRC. If our man comes anywhere close to a phone, camera, or electronic equipment, we will know. They can run, but they can’t hide.

In all these cases, the innovation was an intangible, intellectual one before it was instantiated in equations, laws, routers, or software. One’s whole mental model had to change. It is going beyond what one knows.

human being and bolt on extensions that let them take full advantage of Economics 2.0, and you essentially break their narrative chain of consciousness, replacing it with a journal file of bid/request transactions between various agents; it’s incredibly efficient and flexible, but it isn’t a conscious human being in any recognizable sense of the word.” “All right,” Pierre says slowly. “I think we’ve seen something like that ourselves. At the router.” Sirhan nods, not sure whether he’s referring to anything important. “So you see, there are limits to human progress—but not to progress itself! The uploads found their labor to be a permanently deflating commodity once they hit their point of diminishing utility. Capitalism doesn’t have a lot to say about workers whose skills are obsolete, other than that they should invest wisely while they’re earning and maybe retrain. But just knowing how to invest in Economics 2.0 is beyond an unaugmented human. You can’t retrain as a seagull, can you, and it’s quite as hard to retool for Economics 2.0. Earth is—” He shudders. “There’s a phrase I used to hear in the old days,” Pamela says calmly. “Ethnic cleansing. Do you know what that means, darling idiot daughter? You take people who you define as being of little worth, and first you herd them into a crowded ghetto with limited resources, then you decide those resources aren’t worth spending on them, and bullets are cheaper than bread. ‘Mind children’ the extropians called the posthumans, but they were more like Vile Offspring. There was a lot of that, during the fast sigmoid phase. Starving among plenty, compulsory conversions, the very antithesis of everything your father said he wanted . . .” “I don’t believe it,” Amber says hotly.

That’s crazy! We can’t go the way of—” “Since when has human history been anything else?” asks the woman with the camera on her shoulder—Donna, being some sort of public archivist, is in Sirhan’s estimate likely to be of use to him. “Remember what we found in the DMZ?” “The DMZ?” Sirhan asks, momentarily confused. “After we went through the router,” Pierre says grimly. “You tell him, love.” He looks at Amber. Sirhan, watching him, feels it fall into place at that moment, a sense that he’s stepped into an alternate universe, one where the woman who might have been his mother isn’t, where black is white, his kindly grandmother is the wicked witch of the west, and his feckless grandfather is a farsighted visionary. “We uploaded via the router,” Amber says, and looks confused for a moment. “There’s a network on the other side of it. We were told it was FTL, instantaneous, but I’m not so sure now. I think it’s something more complicated, like a lightspeed network, parts of which are threaded through wormholes that make it look FTL from our perspective. Anyway, Matrioshka brains, the end product of a technological singularity—they’re bandwidth-limited. Sooner or later the posthuman descendants evolve Economics 2.0, or 3.0, or something else, and it, uh, eats the original conscious instigators. Or uses them as currency or something. The end result we found is a howling wilderness of degenerate data, fractally compressed, postconscious processes running slower and slower as they trade storage space for processing power. We were”—she licks her lips—“lucky to escape with our minds. We only did it because of a friend. It’s like the main sequence in stellar evolution; once a G-type star starts burning helium and expands into a red giant, it’s ‘game over’ for life in what used to be its liquid-water zone.

It's not about anthenes, cables, routers.. it is about to turn satellites obsolate.

He’s also collating a series of interviews with resimulated logical positivists from Oxford, England (the ones who haven’t retreated into gibbering near catatonia upon realizing that their state vectors are all members of the set of all sets that do not contain themselves), when he isn’t attempting to establish a sound rational case for his belief that extraterrestrial superintelligence is an oxymoron and the router network is just an accident, one of evolution’s little pranks.

We need to send duplicate ghosts out to each possible router endpoint, wait for an echo, then iterate and repeat. Recursive depth-first traversal.

As another example, my friend and fellow habits expert Nir Eyal purchased an outlet timer, which is an adapter that he plugged in between his internet router and the power outlet. At 10 p.m. each night, the outlet timer cuts off the power to the

There are patents, but they aren’t the crucial thing,” he replies. “The heart of the Cisco router is firmware—software burned into read-only memory or implemented in programmable arrays. Cisco’s product embodies, perhaps, one hundred thousand lines of code that is very skillfully written. It was created by a very small team—maybe two to five people. That chunk

That’s why it’s located in such a lot of famous devices. Wi-Fi is ubiquitous and exceedingly essential for the manner we function our contemporary linked world. How does Wi-Fi paintings? Bluetooth Mesh Philips Hue Wi-fi Although Wi-Fi is commonly used to get right of entry to the internet on portable gadgets like smartphones, tablets, or laptops, in actuality, Wi-Fi itself is used to hook up with a router or other get entry to point which in flip gives the net get entry to. Wi-Fi is a wireless connection to that tool, no longer the internet itself. It also affords get right of entry to to a neighborhood community of related gadgets, that's why you may print photos wirelessly or study a video feed from Wi-Fi linked cameras without a want to be bodily linked to them. Instead of the usage of stressed connections like Ethernet, Wi-Fi uses radio waves to transmit facts at precise frequencies, most typically at 2.4GHz and 5GHz, although there are numerous others used in more niche settings. Each frequency range has some of channels which wireless gadgets can function on, supporting to spread the burden in order that person devices don’t see their indicators crowded or interrupted by other visitors — although that does happen on busy networks.

In an age of network tools, in other words, knowledge workers increasingly replace deep work with the shallow alternative—constantly sending and receiving e-mail messages like human network routers, with frequent breaks for quick hits of distraction. Larger efforts that would be well served by deep thinking, such as forming a new business strategy or writing an important grant application, get fragmented into distracted dashes that produce muted quality.

Other implications of AWS were not immediately apparent. One was that AWS would drive down the cost of launching a new company—to almost zero. Before AWS came along, when you started a tech company you needed to buy expensive servers, storage systems, routers, and database software.

Today we want to glue some wood to some wood. We will get all the surfaces clean with sanding and then by wiping the wood with our coarse brown paper toweling, which itself is limp wood. We will apply the good wood glue, which is the color of banana pudding, to both surfaces, liberally, and align the pieces and press them together. Before the final fit it is important to slide the pieces back and forth just a bit, or twist them a bit, depending on the configuration of the pieces; this lateral friction, as it were, is to displace small pockets of air that may be trapped in the glue if the pieces of wood merely come together head-on. Once we have a good airless fit with plenty of squeezeout we should wipe the excess glue with more paper and clamp the pieces firmly together or effect a clamping by means of weight upon the pieces. Clamping can also be effected by tying the pieces together, often with bungies. The pressure should be that of a very firm handshake. Wood being married to wood likes a good handshake. If there is more squeezeout it may be addressed after this clamping or the dried excess glue may be sanded off later. You can use your anytime minutes on small squeezeout. If one of you would go get me a Musketeers the morning would be better. Some of you know how I put a Musketeers in a Dr. Pepper and how the acid in the Dr. Pepper will make the Musketeers into something like a very tasty sea slug. Which if it goes too long though it can be difficult to lift it out in one piece. I call that the Drooping Musketeer and I don’t really like it, I don’t. At a certain point you have to just stir the Musketeer into the Dr. Pepper. A Baby Ruth looks like a turd. A Butterfinger is wont to explode. Never recap your Dr. Pepper if you are using Butterfinger. I must tell you that because the Surgeon General won’t. The cleaning industry tells you not to combine its stuff but the candy industry does not. If there is no caution statement on a candy bar telling you that it is bad for your health in several ways, chief among them obesity and type II diabetes, it is not finally surprising that they not tell you that under certain conditions the candy unit will explode and perhaps blow your pop bottle apart and blind you, or worse. The good wood glue we use here is pretty set up in an hour. Tomorrow we will start in on the router. The router is essential but many a one thinks it is just some kind of dangerous cosmetic tool. It is not. Get your wood and get to gluing and stop wasting time.

How to Fix Roku Error 014.30 Resolving this issue is generally straightforward, although it can be caused by problems outside of your control. Test your Wi-Fi network with another device, such as your cell phone or computer. Make sure your internet is working properly before you proceed. If not, stop and contact your internet service provider. Using your Roku remote, go to Settings > System > System restart on the Roku menu or Settings > System > Power > System restart if you have a Roku television to restart your Roku system. Reboot your modem and router. Rebooting the modem and router may reset your wireless signal to normal if there is other interference that has caused the Roku to lose signal. When all devices are powered on again, test the Roku to see if the error occurs. If the error still appears, use the Roku remote to go to Settings > Network > Setup connection and select Wireless. Choose your network and enter the network password to ensure it is entered correctly. Select Connect to proceed. If you use MAC address filtering on your network your Roku device may be blocked because the MAC address isn’t recognized. Add the MAC address provided on the error message screen to your router to see if that unblocks your Roku device and returns your service to normal. If you have determined that your Wi-Fi network is working efficiently and all other efforts to resolve error 014.30 have failed, performing a factory reset on your Roku device will restore it to its original settings. Then you can set the Roku up as if it were new and reconnect it to your network to see if it is operating properly. For further information contact :- +1 855-203-0401
