Okay, here’s how I’d do it if I had a fresh ESP-12E on the bench and a 3.3V supply ready to go.
First, treat the 3.3V as sacred: it must be a proper regulated source able to supply the ESP8266’s Wi‑Fi peaks. Real-world bursts can hit 300–400mA, so I make sure the regulator or supply can deliver at least 500mA (I usually pick 800–1000mA headroom). Right at the module I solder a 100 µF (low-ESR electrolytic or tantalum) and a 0.1 µF ceramic across Vcc and GND — the big cap catches the bursts, the small cap kills HF noise. A ferrite bead or a small series R (4–10Ω) helps dampen ringing if I see instability.
Second, get the pins and reset right. Pull CH_PD (EN) high with ~10k, pull RST high (10k) so it doesn’t float, and set GPIO0 high and GPIO2 high while keeping GPIO15 low for normal boot. Don’t power the module from an FTDI or a weak 3.3V pin unless you’ve checked current capability. Also, never feed 5V into the ESP pins — use level shifting if your MCU runs at 5V.
Finally, test it: put the module on a simple LED blink or Wi‑Fi scan and watch the supply with a multimeter or, better, an oscilloscope. If Vcc dips under ~3.0V during TX you’ll get brownouts; if that happens add bigger caps, a beefier regulator, or a small switching regulator (buck) with low noise. I usually prefer a good LDO with low dropout and solid output caps or a well-filtered switching regulator if stepping down from 5V, and that combo keeps my ESP-12E happy and reliable.

Totally hit this snag before — you open a file in vim, make your edits, and then bam: permission denied when you try to save. The neat little trick I use most often is this one-liner from inside vim: :w !sudo tee % >/dev/null
What that does is write the buffer to the sudoed 'tee' command, which will overwrite the original file as root. The % expands to the current filename, so the full flow is: vim hands the file contents to sudo tee, tee writes it with elevated rights, and the >/dev/null part hides the tee output so your buffer stays as-is. After that you can do :q to quit. I like this because it’s fast and doesn’t require reopening the file as root.
If you want a slightly cleaner approach, consider using sudoedit (sudo -e) to open files with your preferred editor as a temporary safe copy — it edits a temp file and then installs it as root, which is safer from a security perspective. For convenience I sometimes create a vim command or mapping, like cnoremap W!! w !sudo tee % >/dev/null, so typing :W!! saves without fuss. Also, if you frequently need root saves, the plugin 'sudo.vim' (provides commands like :SudoWrite) is worth installing. Each method has trade-offs: the tee trick is quick, sudoedit is safer, and opening vim with sudo from the start (sudo vim file) works but bypasses some safety models.

If I had to pick a short list right off the bat, I'd put chrome-vanadium and S2 tool steel at the top for most durable vim wrench models. Chrome-vanadium (Cr-V) is what you'll see on a lot of high-quality ratchets and hex sets—it balances hardness and toughness well, resists wear, and takes a nice finish. S2 is a shock-resisting tool steel that's common for bits and hex keys designed to take a lot of torque without snapping. For heavy, impact-style use, chrome-molybdenum (Cr-Mo) or 4140/6150 alloys are common because they absorb shocks better and can be heat-treated for high strength.
Finish and heat treatment matter as much as base alloy. Hardened and tempered tools in the HRC 52–62 range tend to last; too hard and they become brittle, too soft and they round off. Coatings like black oxide, phosphate, or nickel chrome help with corrosion; TiN or other nitriding can up wear resistance. In short: pick S2 or Cr-V for everyday durability, Cr-Mo for impact-duty, and pay attention to heat treatment and finish for real longevity. I tend to favor sets with solid forging and clear HRC specs—that’s saved me from snapping a hex at an awkward moment.

Honestly, I treat my tools a little like prized comics on a shelf — I handle them, clean them, and protect them so they last. When it comes to a vim wrench, the simplest habit is the most powerful: wipe it down after every use. I keep a small stash of lint-free rags and a bottle of light machine oil next to my bench. After I finish a job I wipe off grit and sweat, spray a little solvent if there’s grime, dry it, then apply a thin coat of oil with a rag so there’s no wet residue to attract rust.
For bits of surface rust that sneak in, I’ll use fine steel wool or a brass brush to take it off, then neutralize any remaining rust with a vinegar soak followed by a baking soda rinse if I’ve used acid. For long-term protection I like wax — a microcrystalline wax like Renaissance or even paste car wax gives a water-repellent layer that’s pleasantly invisible. If the wrench has moving parts, I disassemble and grease joints lightly and check for play.
Storage matters almost as much as treatment: a dry toolbox with silica gel packets, not left in a damp car or basement, keeps rust away. Little routines add up — a five-minute wipe and oil once a month will make that wrench feel like new for years.

Gohan's power level has always been a hot topic among fans, and honestly, it's pretty fascinating to dive into. In 'Dragon Ball Z', right from the beginning, Gohan was no ordinary kid. He had immense potential that was hinted at during his first fight against Raditz. While Goku and Vegeta are often highlighted as the top-tier fighters, Gohan’s character had an advantage very few could match: his latent power. Remember when he powered up in the Cell Games? That moment when he transformed into Super Saiyan 2 was legendary! He even managed to defeat Cell, the ultimate villain of that saga, which showed that he had the potential to surpass even his father at times. It’s like he had this hidden reservoir of strength, just waiting for the right moment to explode onto the scene.
Comparatively, while characters like Vegeta and Goku train tirelessly to push their limits, Gohan’s strength was often a combination of training and emotional turmoil; it's almost poetic. During the Buu saga, though, he didn’t maintain that peak power for long. With distractions like studying and living a 'normal life', fans saw a dip in his power. The contrast between Gohan in the Cell saga and then in 'Dragon Ball Super' is stark. While he had the potential to outclass others, he chose a different path, letting his dueling abilities take a backseat. It's super interesting to see how Gohan's narrative reflects a more relatable journey, balancing personal life and heroics, unlike some of the others who seemed singularly focused on strength.
Yet, if we line up Gohan against seasoned fighters like Piccolo or Tien, it's clear he holds the edge with the raw power he could tap into—when he needed to. But it also raises a discussion about personal choices in the realm of strength. The Z Fighters, with their relentless training, maybe represented that classic shonen approach, while Gohan was more symbolic of personal struggle and growth. His journey resonates deeply, making him more than just a fighter; he’s a character navigating the complexities of responsibility, family, and identity, making his power so unique in comparison to others.
You'll find his evolution through training and personal circumstances very relatable, emphasizing that strength isn’t just about raw power but about choosing how one uses that power—and I think that’s what makes Gohan’s story even more compelling. We all love those electrifying battles, but Gohan brings that touch of emotional depth to the fray, don’t you think?
