When asking "what's the default gateway?", more often than not, the real question you have is "what's the gateway to IP address X", which would be: ip route get X

I can take "mtu 1500" part, and sort-of "qdisc", but what's up with repeating obscure parameters at their default values, for each and IP address: valid_lft forever preferred_lft forever

Not to disagree with you, but - what "modern" alternative would you recommend as a replacement for "wapptclsh", which is a compact statically-linked binary with wapp and sqlite libraries baked in? Binary "wapptclsh&

My biggest gripe with Zoom is that they have tech in place to seamlessly support open-standard connections (SIP & XMPP), but make their utmost to sweep both under the rug: SIP is $49/month/user and XMPP server isn't adver

I have a problem with those two "vulnerabilities" listed: - Available Serial Interface (referring to easy-to-solder console port pads on PCB, accessible once you tear device apart); - Weak Default Credentials (referring to weak ro

In general, servers should have nothing to do with end-to-end encryption, except for not actively breaking it. OMEMO in particular uses: - Personal Eventing Protocol (PEP, XEP-0163) to transport key material; and - core RFC3920/RFC6120

Unfortunately, this sort of attitude is not unheard of among proprietary software vendors - see for example FTDI bricking your hardware if they think it's counterfeit: https://news.ycombinator.com/item?id=8493849

When using this awesome piece of software, you probably want to give a miss to the "blue pill" board recommended in the README file, and go instead with ST-Link v.2 clone, which has identical hardware and pricetag, while being con

L2 bridge of WiFi access point to anything else (like wired Ethernet, for example) "just works". On the other hand, L2 bridge of WiFi station to anything else (including STA<->AP bridge for a repeater operation) is quite

Battery would probably be a no-go here. You can't put repeater into sleep mode[#], and in active AP+STA mode ESP8266 takes 70mA @3.3v, which is 3-4 times lower than best purpose-made wifi repeaters, but will still drain 3000mA*h batter

5mbps is about the best case (all 3 nodes on the same table). In more realistic deployment, it'll be much less. So, why so slow? TL;DR: Too little RAM on ESP8266. WiFi is half-duplex, i.e. in basic scenario (no MIMO; all stations close

"Mesh" (in thick air-quotes) here is just a way for self-organizing for shortest uplink hop count. Strict uplink-downlink hierarchy still stays regardless of whether "manual uplink" or "mesh" mode is in use. Ea

Dynamic routing is the hardest part of mesh network. By using NAT martin-ger has side-stepped need to have routing altogether (it's just default gateway for each node like that). But that of course comes at cost - reaching your devic

Two limitations here are worth keeping in mind: - Throughput is not stellar (less than 1 mbit/s in a realistic setup); - This is not a real IEEE 802.11s mesh, but rather some clever mechanism on how a node can select an "uplink&qu

Most likely mechanism for this incident was: 1) external magnet messed up heads movement closed control loop (internal drive's magnets + voice coil + positioning marks on the platters), and as a result head actual position became diffe
