] | The most standard way of playing melee Zer0 is to go all the way down the `Bloodshed` tree for `Many Must Fall`. Definitely skip `Grim` because it ruins how you will be playing and `Resurgence` is useless with the weapons you will be using. See this [post](http://forums.gearboxsoftware.com/showthread.php?t=254652) for the complete melee formula (in short melee damage is based purely on your level and other modifiers, weapon damage is irrelevant unless it specifically says it does extra melee damage) - you can use this to min/max the skills. `Many Must Fall` is better than `Death Bl0ss0m` typically unless you are doing raid bosses so switch if you are farming raid bosses.
Your standard setup includes:
* [Rubi](http://borderlands.wikia.com/wiki/Rubi) (preferably with `Slag` and `Evisceration`)
+ An alternative is to use [Law](http://borderlands.wikia.com/wiki/Law_%28Borderlands_2%29) with [Order](http://borderlands.wikia.com/wiki/Order) but I believe you will do less damage overall
+ This is how you are going to recover HP - ~12% damage you do with `Rubi` is gained as HP, you will often go from 1% to 100% HP in one hit
+ Any damage done while holding `Rubi`, not just damage done with Rubi is recovered as HP
* [Love Thumper](http://borderlands.wikia.com/wiki/Love_Thumper) (preferably with one of the immunities)
+ This is the better alternative to Order for the damage that it produces which means better HP recovery
+ The reason `Love Thumper` is better than `Order` is because you don't need to manage your shield and the higher Roid damage
+ Another alternative is [Hide of Terramorphous](http://borderlands.wikia.com/wiki/Hide_of_Terramorphous) but again you will need to manage your sheilds
* [Rapier](http://borderlands.wikia.com/wiki/Rapier) (also preferably with Slag)
+ the 200% modifier is huge and if you look around you can find videos of Zer0 doing max damage in one melee swing
+ Swap and use this as necessary - DO NOT underestimate this weapon, this is a huge boost to your melee damage compared to `Rubi`
+ This requires [Captain Scarlett and Her Pirate's Booty](http://borderlands.wikia.com/wiki/Captain_Scarlett_and_Her_Pirate%27s_Booty) DLC which is pretty good overall
* [Proficiency Relic](http://borderlands.wikia.com/wiki/Proficiency_Relic) is the most common relic used
* Class mod is up to your preference
* [Storm Front](http://borderlands.wikia.com/wiki/Storm_Front)
+ Often used because it has consistent damage so paired with Rubi it has good HP recovery and the explosion can break your shield while the Tesla won't damage you
* I usually keep a Rocket Launcher, Sniper Rifle, or [Dahlminator](http://borderlands.wikia.com/wiki/Dahlminator) in the remaining slots for FFYL, long distance, or flying enemies
Remember Roid damage is a big contributor to your overall damage so your shield should usually be depleted - this is why `Grim` is useless and detrimental in this build.
With `Rubi` in hand you can pretty much just trade blows with most things. If you are using something similar to this build, your damage output in UVHM will be "sufficient" as well as your sustainability.
If anyone tells you Zer0 is not viable, they are either not using something like this or do not know what they are talking about. As far as I know Salvador is the only one that comes closest/surpasses Zer0 in damage output. Gaige's Deathtrap and Axton's turret(s) don't come anywhere close to what melee Zer0 can dish out.
Yes, this does mean pretty much every gun you get is near useless and their damage is irrelevant (remember you still have 2 slots you need to fill). The only values that matter in term of damage is your level, melee modifier, and skills that modifies melee damage. As far as I know, nothing of value was added in UVHM for Zer0 players.

+ [Alternative](http://www.youtube.com/watch?v=AC6tvc59gss) to melee Zer0 using B0re on Hyperius | I am currently doing solo UVHM as Hybrid Zero, and it's been a breeze. Slag -> correct elemental weapon—even badasses and super badasses go down in few hits.
(I don't really buy that "getting killed in 1-2 hits.
My Zer0 has 400k health and is perfectly capable of soaking damage.)
Although I do confess that the constant weapon swapping gets really tiring after a while, it's so routine and tedious:
shielded bandit -> slag -> shock -> fire -> reload all weapons -> next enemy-> rinse and repeat ad nauseam...
But I wouldn't say it's hard. Just use those elemental weapons and remember to slag the hell out of everything, and a few well placed shots are all you need to take down the baddies.
For melee builds, use slag singularity grenades before going for Many Must Fall, those executions deal insane amounts of damage on slagged enemies.
Kunai also benefits from any bonus for "melee damage" since it registers as a melee.
B0re can totally devastate groups of enemies. Just drag them together with singularity slag and fire away. If done right, everyone is dead before your magazine is empty. |

] | This is an Assassin equipment guide (with some skill pointers) for Ultimate Vault Hunter Mode. It's not the only right solution, nor do I claim this to be the *best* possible, but it is something that worked for me, making the UVHM easy to solo.
NOTE: This guide does not include any Legendary or E-tech weapons, mods or relics because getting them is based on very low drop rate and hours of farming on specific bosses. (e.g.: Conference Call requires you to farm The Warrior or Handsome Jack.) This guide also does not include any quest-specific items, since getting them requires you to complete those quests first. Telling you to use some equipment that you won't get until late into the game would be rather pointless - if you're already to the endgame, why would you be needing this?
Quick analysis:
What's Zer0 great at, and where is he not so great?
Zer0 is really good at everything. Depending on your choice of skills and equipment, he can do just about anything fairly well - even tanking. This guide is geared towards a solo game though, so there won't be a lot of coverage on such co-op strategies.
His primary strength is dealing damage, in one of two ways: Either massively painful single blows every 15-20 seconds, or a constant stream of high DPS through damage bonus modifiers. Both styles work out to about the same rate of damage in the end, so which way you play is really up to you.
Weapons:
Forget any non-elemental guns. While you may love Jakobs guns for their ridiculously high raw damage stats, they're really not so useful in UVHM. UVHM puts heavy weight on exploiting your enemy's elemental weaknesses (and, conversely, greatly beefs up the enemies' elemental resistances) and effective use of multiple weapons. Slag damage is also greatly boosted. This is why you should notice that your weapon swap speed is slightly increased in UVHM. If you're playing UVHM, you're sure to find a whole new appreciation for Maliwan!
Always keep at least one each of Slag, Fire, Corrosive, and Shock weaponry on hand.
Make sure your Slag weapon has a *high chance* to slag. The gun damage is trivial - it can even be a level 1 gun, so long as it has a very high Slag percentage. You're not using the gun to deal the bulk of your damage in the fight. You're using it to enhance the damage your other guns deal. You don't want to throw yourself into the fray with a gun that constantly fails to apply Slag.
Pro Tip: Have 2 Slag weapons - one for close range, one for long range.
For your Shock weapon, you can use a Sniper Rifle. Shock damage has no penalty on flesh or armor, but deals *massive* damage on Shields. This means that a high-powered Shock Sniper Rifle can take out enemy Shields even without Slag. Still, you may want to carry a rapid-firing Shock SMG just in case. (Even though most heavy troopers don't carry shields - I guess it's an ego thing.)
For Fire weapons, I really recommend an SMG. After you've applied Slag, you can take down even Badass-level enemies with a rapid-firing Fire SMG. Moxxi's Good touch is great for this. You can get the Good Touch during any part of the game as long as you have access to Sanctuary. Just go to Moxxi's bar and tip her enough money (somewhere between $20k-$75k - anecdotal evidence varies). Good Touch always scales to your level, is extremely powerful, and returns 2% of the damage dealt back to you as a health recharge! You can go back to Moxxi any time to tip her again for a new one, which again will be scaled to your current level, so don't worry about "out-growing" this gun.
For corrosive weapons: SMG, SMG, SMG! Alternately, Shotgun. Most of the armored enemies you'll encounter are fast-moving Psychos (though now we call them Lunatics) or Hyperion loaders. Most of these will have hard-to-hit Critical locations, and will either be in your face with Melee or swarming you with Machine Gun fire and Grenades. This is not a good place to be relying on a Sniper Rifle. Instead, Slag the Lunatics and unload that SMG or Shotgun in their face - like everyone is Face McShooty! Loaders are about the same - they can quickly close the gap. Those pesky Surveyors aren't going to just hang around waiting for you to Snipe their armored core. Instead, blast them to bits with a Shotgun while they try their flyby attacks.
Grenades:
Yes! Lots of Grenades! Your best choice here is for Singularity or MIRV with a huge radius. Activate Decepti0n and drop grenades everywhere (this does not break Decepti0n) while you run for cover! This is extremely useful when getting pestered by those Stalkers, especially since you can see them while in Decepti0n even when they're invisible.
Pro Tip (especially for Solo players only): Throw a Slag Singularity, pause the game, switch to an Explosive MIRV and throw it where you dropped the Singularity. Watch the meat fountain! Instant profit!
Shields:
Anshin adaptive Shields. Not only do they give you a nice damage resistance bonus (matching resistance to the last damage type received), they also increase your health. Zer0 is all about health, especially considering that he is the only class with no passive Shield bonuses but all kinds of ways to regenerate *huge* amounts of health in *seconds*! If you're lucky enough to find a Purple-grade Anshin Shield (which offers up to 60% damage resistance) you can pretty much just stand idle while a Bruiser shotguns you to the face!
If you're more of a slash-and-dash player, you might prefer to use a shield that adds Roid damage. However, these usually have very short recharge delays which make them fairly difficult to use effectively (since the shield has to stay discharged to give you the bonus). The best use for Melee with Zer0 is to deliver the Killing Bl0ws to quickly dispatch enemies with low health. You don't need Roid shields for that, and you can even get a bonus with Resurgence which recovers health on every Melee kill.
Pro Tip: Carry one "elemental immunity" Shield of each element type on your backpack, regardless the level or type of Shields. You never know when you'll bump into a pack of enemies that are using just one elemental type. You'll *really* want that Shock immunity when the Super Badass Shock Skag decides to fry your brains with electric barks, while his Shock-charged Pups gnaw on your legs!
Relics:
Health relics - buff that HP! If you're using Anshin Shields as recommended, your Shield capacity is going to be low. Compensate for that by getting your Health as high as you can!
Class Mods:
Use a Survivor Class Mod. They all give extra HP and HP regeneration, and many come with some nice skill bonuses. Regenerating 600 HP/s may seem a bit slow when you have over 300k HP, but you'll be really glad your HP is constantly recharging when you're ducking for cover under heavy Buzzard fire. It's also real nice to know that, when you're traveling about, you won't have to shell out at the nearest Zed's when you get to town - by the time you get there, your health will already be full again!
The 8k HP bonus might not look like much, when you consider your enemies are blowing away 50k at a time. But when you survive that crazy blaster master rocket bombardment with just a few hundred HP left - giving you a chance to pop Decepti0n and run for cover, *while* regaining health - you'll be really glad you chose a Survivor mod!
Other decent Class Mod choices are Infiltrator and Ninja, if they suit your play style and Skill setups better.
Skills:
A full build layout is too much to cover in this post, but I'll give a few pointers.
B0re, B0re, B0re, B0re, B0re! No matter what your play style, take this one skill! You'll learn to love it, once you get the hang of it's effective use. It may also give you a pleasant suprise in a fight against Bunker. ;)
Execute. Take it, take it, take it, take it, take it! Combined with Killing Bl0w, this one can win you a lot of losing battles.
Innervate. At level 5, this skill lets you recover up to 24% of your max HP (which should be fairly high, if you've followed the above recommendations) whenever you drop into Decepti0n. Who can really say no to a fresh 24% HP refill available every 15 seconds? And if you've followed my recommendations so far, 24% of your max HP should be **a lot** of HP!
Rising Sh0t. Using those elemental SMGs like I told you to? Then meet your new best friend! At level 5, Rising Sh0t makes your 5th consecutive hit (and every consecutive hit afterwards) have a 50% damage bonus. With a really nice Survivor mod, this can be boosted to 110%! You *want* that extra damage! Unload your SMG on those baddies! With a 30-bullet mag, 25 bullets could be doing double damage or better! It's like having a co-op partner, or your own special way of Gunzerking! Multiply the damage with Slag and proper elemental selection, and the bad guys just don't stand a chance!
Unf0rseen - forget it!
Level 5 deals about 300k Shock damage, level 10 via Class Mods can deal almost 1M. But this has a *very* short radius, so usually the enemies you'll use this against are Suicide Psychos (which are going to, well, suicide anyway) or other relatively trivial grunts that just like being up in your face. 300k to 1M damage every 15-20 seconds is a pittance against Bosses and Badasses. With Slag, followed by the right elemental weapon, and Rising Sh0t, you'll be dealing that 300k on every shot instead!
Personal Note: I've played the game through up to level 61 with three different Zer0s. I've soloed Raid Bosses like Terramorphous, Pete, Hyperious, and Master Gee even *without* Legendary equipment! (Though once I did obtain some "Dahlicious" Orange goodness, they became even less of a hassle to defeat! Those Legendaries make a *huge* difference in terms of power - but that's another story.) | The most standard way of playing melee Zer0 is to go all the way down the `Bloodshed` tree for `Many Must Fall`.

] | The most standard way of playing melee Zer0 is to go all the way down the `Bloodshed` tree for `Many Must Fall`. Definitely skip `Grim` because it ruins how you will be playing and `Resurgence` is useless with the weapons you will be using. See this [post](http://forums.gearboxsoftware.com/showthread.php?t=254652) for the complete melee formula (in short melee damage is based purely on your level and other modifiers, weapon damage is irrelevant unless it specifically says it does extra melee damage) - you can use this to min/max the skills. `Many Must Fall` is better than `Death Bl0ss0m` typically unless you are doing raid bosses so switch if you are farming raid bosses.
Your standard setup includes:
* [Rubi](http://borderlands.wikia.com/wiki/Rubi) (preferably with `Slag` and `Evisceration`)
+ An alternative is to use [Law](http://borderlands.wikia.com/wiki/Law_%28Borderlands_2%29) with [Order](http://borderlands.wikia.com/wiki/Order) but I believe you will do less damage overall
+ This is how you are going to recover HP - ~12% damage you do with `Rubi` is gained as HP, you will often go from 1% to 100% HP in one hit
+ Any damage done while holding `Rubi`, not just damage done with Rubi is recovered as HP
* [Love Thumper](http://borderlands.wikia.com/wiki/Love_Thumper) (preferably with one of the immunities)
+ This is the better alternative to Order for the damage that it produces which means better HP recovery
+ The reason `Love Thumper` is better than `Order` is because you don't need to manage your shield and the higher Roid damage
+ Another alternative is [Hide of Terramorphous](http://borderlands.wikia.com/wiki/Hide_of_Terramorphous) but again you will need to manage your sheilds
* [Rapier](http://borderlands.wikia.com/wiki/Rapier) (also preferably with Slag)
+ the 200% modifier is huge and if you look around you can find videos of Zer0 doing max damage in one melee swing
+ Swap and use this as necessary - DO NOT underestimate this weapon, this is a huge boost to your melee damage compared to `Rubi`
+ This requires [Captain Scarlett and Her Pirate's Booty](http://borderlands.wikia.com/wiki/Captain_Scarlett_and_Her_Pirate%27s_Booty) DLC which is pretty good overall
* [Proficiency Relic](http://borderlands.wikia.com/wiki/Proficiency_Relic) is the most common relic used
* Class mod is up to your preference
* [Storm Front](http://borderlands.wikia.com/wiki/Storm_Front)
+ Often used because it has consistent damage so paired with Rubi it has good HP recovery and the explosion can break your shield while the Tesla won't damage you
* I usually keep a Rocket Launcher, Sniper Rifle, or [Dahlminator](http://borderlands.wikia.com/wiki/Dahlminator) in the remaining slots for FFYL, long distance, or flying enemies
Remember Roid damage is a big contributor to your overall damage so your shield should usually be depleted - this is why `Grim` is useless and detrimental in this build.
With `Rubi` in hand you can pretty much just trade blows with most things. If you are using something similar to this build, your damage output in UVHM will be "sufficient" as well as your sustainability.
If anyone tells you Zer0 is not viable, they are either not using something like this or do not know what they are talking about. As far as I know Salvador is the only one that comes closest/surpasses Zer0 in damage output. Gaige's Deathtrap and Axton's turret(s) don't come anywhere close to what melee Zer0 can dish out.
Yes, this does mean pretty much every gun you get is near useless and their damage is irrelevant (remember you still have 2 slots you need to fill). The only values that matter in term of damage is your level, melee modifier, and skills that modifies melee damage. As far as I know, nothing of value was added in UVHM for Zer0 players.

Some interesting video:
* [Max damage done in a single hit](http://www.youtube.com/watch?v=0iduz8Aj7HI) - I believe it is because [Death Mark](http://borderlands.wikia.com/wiki/Deathmark) from multiple players can stack

2) they fire 2 homing nades that home in on opponents
3) the homing nades have an almost 100% chance to slag on explosion
Toss a Magic Missle. Let it slag some folks while you switch to the appropriate elemental sniper (fire for flesh, corrosive for armor (yellow health bar), shock for shields, or explosive for all-around decent damage on everything). Let the homing Magic Missles do their trick.
This ensures you always get slagged enemies, and then you pick them off. If you team it with something like the Pimpernal from Scarlett's Pirate Booty DLC you can do some major damage. Problem with UVHM is that levelling scales even more exponentially, so weapons that are 2-3 levels behind get useless very fast.

] | This is an Assassin equipment guide (with some skill pointers) for Ultimate Vault Hunter Mode. It's not the only right solution, nor do I claim this to be the *best* possible, but it is something that worked for me, making the UVHM easy to solo.
NOTE: This guide does not include any Legendary or E-tech weapons, mods or relics because getting them is based on very low drop rate and hours of farming on specific bosses. (e.g.: Conference Call requires you to farm The Warrior or Handsome Jack.) This guide also does not include any quest-specific items, since getting them requires you to complete those quests first. Telling you to use some equipment that you won't get until late into the game would be rather pointless - if you're already to the endgame, why would you be needing this?
Quick analysis:
What's Zer0 great at, and where is he not so great?
Zer0 is really good at everything. Depending on your choice of skills and equipment, he can do just about anything fairly well - even tanking. This guide is geared towards a solo game though, so there won't be a lot of coverage on such co-op strategies.
His primary strength is dealing damage, in one of two ways: Either massively painful single blows every 15-20 seconds, or a constant stream of high DPS through damage bonus modifiers. Both styles work out to about the same rate of damage in the end, so which way you play is really up to you.
Weapons:
Forget any non-elemental guns. While you may love Jakobs guns for their ridiculously high raw damage stats, they're really not so useful in UVHM. UVHM puts heavy weight on exploiting your enemy's elemental weaknesses (and, conversely, greatly beefs up the enemies' elemental resistances) and effective use of multiple weapons. Slag damage is also greatly boosted. This is why you should notice that your weapon swap speed is slightly increased in UVHM. If you're playing UVHM, you're sure to find a whole new appreciation for Maliwan!
Always keep at least one each of Slag, Fire, Corrosive, and Shock weaponry on hand.
Make sure your Slag weapon has a *high chance* to slag. The gun damage is trivial - it can even be a level 1 gun, so long as it has a very high Slag percentage. You're not using the gun to deal the bulk of your damage in the fight. You're using it to enhance the damage your other guns deal. You don't want to throw yourself into the fray with a gun that constantly fails to apply Slag.
Pro Tip: Have 2 Slag weapons - one for close range, one for long range.
For your Shock weapon, you can use a Sniper Rifle. Shock damage has no penalty on flesh or armor, but deals *massive* damage on Shields. This means that a high-powered Shock Sniper Rifle can take out enemy Shields even without Slag. Still, you may want to carry a rapid-firing Shock SMG just in case. (Even though most heavy troopers don't carry shields - I guess it's an ego thing.)
For Fire weapons, I really recommend an SMG. After you've applied Slag, you can take down even Badass-level enemies with a rapid-firing Fire SMG. Moxxi's Good touch is great for this. You can get the Good Touch during any part of the game as long as you have access to Sanctuary. Just go to Moxxi's bar and tip her enough money (somewhere between $20k-$75k - anecdotal evidence varies). Good Touch always scales to your level, is extremely powerful, and returns 2% of the damage dealt back to you as a health recharge! You can go back to Moxxi any time to tip her again for a new one, which again will be scaled to your current level, so don't worry about "out-growing" this gun.
For corrosive weapons: SMG, SMG, SMG! Alternately, Shotgun. Most of the armored enemies you'll encounter are fast-moving Psychos (though now we call them Lunatics) or Hyperion loaders. Most of these will have hard-to-hit Critical locations, and will either be in your face with Melee or swarming you with Machine Gun fire and Grenades. This is not a good place to be relying on a Sniper Rifle. Instead, Slag the Lunatics and unload that SMG or Shotgun in their face - like everyone is Face McShooty! Loaders are about the same - they can quickly close the gap. Those pesky Surveyors aren't going to just hang around waiting for you to Snipe their armored core. Instead, blast them to bits with a Shotgun while they try their flyby attacks.
Grenades:
Yes! Lots of Grenades! Your best choice here is for Singularity or MIRV with a huge radius. Activate Decepti0n and drop grenades everywhere (this does not break Decepti0n) while you run for cover! This is extremely useful when getting pestered by those Stalkers, especially since you can see them while in Decepti0n even when they're invisible.
Pro Tip (especially for Solo players only): Throw a Slag Singularity, pause the game, switch to an Explosive MIRV and throw it where you dropped the Singularity. Watch the meat fountain! Instant profit!
Shields:
Anshin adaptive Shields. Not only do they give you a nice damage resistance bonus (matching resistance to the last damage type received), they also increase your health. Zer0 is all about health, especially considering that he is the only class with no passive Shield bonuses but all kinds of ways to regenerate *huge* amounts of health in *seconds*! If you're lucky enough to find a Purple-grade Anshin Shield (which offers up to 60% damage resistance) you can pretty much just stand idle while a Bruiser shotguns you to the face!
If you're more of a slash-and-dash player, you might prefer to use a shield that adds Roid damage. However, these usually have very short recharge delays which make them fairly difficult to use effectively (since the shield has to stay discharged to give you the bonus). The best use for Melee with Zer0 is to deliver the Killing Bl0ws to quickly dispatch enemies with low health. You don't need Roid shields for that, and you can even get a bonus with Resurgence which recovers health on every Melee kill.
Pro Tip: Carry one "elemental immunity" Shield of each element type on your backpack, regardless the level or type of Shields. You never know when you'll bump into a pack of enemies that are using just one elemental type. You'll *really* want that Shock immunity when the Super Badass Shock Skag decides to fry your brains with electric barks, while his Shock-charged Pups gnaw on your legs!
Relics:
Health relics - buff that HP! If you're using Anshin Shields as recommended, your Shield capacity is going to be low. Compensate for that by getting your Health as high as you can!
Class Mods:
Use a Survivor Class Mod. They all give extra HP and HP regeneration, and many come with some nice skill bonuses. Regenerating 600 HP/s may seem a bit slow when you have over 300k HP, but you'll be really glad your HP is constantly recharging when you're ducking for cover under heavy Buzzard fire. It's also real nice to know that, when you're traveling about, you won't have to shell out at the nearest Zed's when you get to town - by the time you get there, your health will already be full again!
The 8k HP bonus might not look like much, when you consider your enemies are blowing away 50k at a time. But when you survive that crazy blaster master rocket bombardment with just a few hundred HP left - giving you a chance to pop Decepti0n and run for cover, *while* regaining health - you'll be really glad you chose a Survivor mod!
Other decent Class Mod choices are Infiltrator and Ninja, if they suit your play style and Skill setups better.
Skills:
A full build layout is too much to cover in this post, but I'll give a few pointers.
B0re, B0re, B0re, B0re, B0re! No matter what your play style, take this one skill! You'll learn to love it, once you get the hang of it's effective use. It may also give you a pleasant suprise in a fight against Bunker. ;)
Execute. Take it, take it, take it, take it, take it! Combined with Killing Bl0w, this one can win you a lot of losing battles.
Innervate. At level 5, this skill lets you recover up to 24% of your max HP (which should be fairly high, if you've followed the above recommendations) whenever you drop into Decepti0n. Who can really say no to a fresh 24% HP refill available every 15 seconds? And if you've followed my recommendations so far, 24% of your max HP should be **a lot** of HP!
Rising Sh0t. Using those elemental SMGs like I told you to? Then meet your new best friend! At level 5, Rising Sh0t makes your 5th consecutive hit (and every consecutive hit afterwards) have a 50% damage bonus. With a really nice Survivor mod, this can be boosted to 110%! You *want* that extra damage! Unload your SMG on those baddies! With a 30-bullet mag, 25 bullets could be doing double damage or better! It's like having a co-op partner, or your own special way of Gunzerking! Multiply the damage with Slag and proper elemental selection, and the bad guys just don't stand a chance!
Unf0rseen - forget it!
Level 5 deals about 300k Shock damage, level 10 via Class Mods can deal almost 1M. But this has a *very* short radius, so usually the enemies you'll use this against are Suicide Psychos (which are going to, well, suicide anyway) or other relatively trivial grunts that just like being up in your face. 300k to 1M damage every 15-20 seconds is a pittance against Bosses and Badasses. With Slag, followed by the right elemental weapon, and Rising Sh0t, you'll be dealing that 300k on every shot instead!
Personal Note: I've played the game through up to level 61 with three different Zer0s. I've soloed Raid Bosses like Terramorphous, Pete, Hyperious, and Master Gee even *without* Legendary equipment! (Though once I did obtain some "Dahlicious" Orange goodness, they became even less of a hassle to defeat! Those Legendaries make a *huge* difference in terms of power - but that's another story.) | I am currently doing solo UVHM as Hybrid Zero, and it's been a breeze. Slag -> correct elemental weapon—even badasses and super badasses go down in few hits.
(I don't really buy that "getting killed in 1-2 hits.
My Zer0 has 400k health and is perfectly capable of soaking damage.)
Although I do confess that the constant weapon swapping gets really tiring after a while, it's so routine and tedious:
shielded bandit -> slag -> shock -> fire -> reload all weapons -> next enemy-> rinse and repeat ad nauseam...
But I wouldn't say it's hard. Just use those elemental weapons and remember to slag the hell out of everything, and a few well placed shots are all you need to take down the baddies.
For melee builds, use slag singularity grenades before going for Many Must Fall, those executions deal insane amounts of damage on slagged enemies.
Kunai also benefits from any bonus for "melee damage" since it registers as a melee.
B0re can totally devastate groups of enemies. Just drag them together with singularity slag and fire away. If done right, everyone is dead before your magazine is empty. |

To make querying easier I first ensure all records contain all keys with `KeyUnion`. Then create the `Dataset`.
```
dat = Dataset@KeyUnion@associations
```
Now with `GroupBy` a single hierarchical `Dataset` can be created.
```
gdat = dat[GroupBy[#"key" &], GroupBy[#"date" &]]
```
It is kind of difficult to see the structure so we can implicitly use `Dataset` to show it. **Note** *this is only needed to show the structure in a visually friendly way.* You don't need to do this on your larger dataset.
```
gdat[All, Dataset, Dataset]
```
Now you can query the hierarchical dataset for your values.
```
gdat[1, All, All, "1st"]
```
```
gdat[All, "2016-04-12", All, "3rd"]
```
```
gdat[2, "2016-04-12"]
```
And so on.
Hope this helps. | Not sure if this can be done using `JoinAcross`.
```
associations = {
<|"date" -> "2016-04-12", "key" -> 1, "1st" -> 0.9652777777777778`,
"2nd" -> 0.8867924528301887`, "3rd" -> 0.49074074074074076`|>,

71,981,738 | Hi I would like to ask for the aes mapping, if I want to have the mean of wages based on age group but I do not want to adjust the data table, is there a function I can call in the ggplot to have the mean wages based on their age group?
```
ab_final <- ab %>%
group_by(agegroup,haveKids,educationLevel) %>%
summarise(Wage = mean(Wage), Expenses = mean(Expenses)) %>%
mutate(Wage = ifelse(haveKids, -Wage, Wage), Expenses = ifelse(haveKids,Expenses,-Expenses))
head (ab_final)
```
| agegroup | haveKids | educationLevel | Wage | Expenses |
| --- | --- | --- | --- | --- |
| 18-25 | FALSE | Bachelors | 73428. | 18582. |
| 18-25 | FALSE | Graduate | 90757. | 21441. |
| 18-25 | FALSE | HighSchoolOrCollege | 36027. | 15956. |
| 18-25 | FALSE | Low | 36598. | 19367. |
| 18-25 | TRUE | Bachelors | -98265. | -24964. |
| 18-25 | TRUE | Graduate | -111545. | -25002. |
```
p <- ggplot(ab_final, aes(x = Wage, y = agegroup, fill = haveKids)) +
geom_col() +
scale_x_continuous(breaks = seq(-60000, 60000, 30000),
labels = paste0("$",as.character(c(seq(60, 0, -30), seq(30, 60, 30))),"k")) +
labs (x = "Annual Average Wage (USD)", y = "Age Group", title='Ohio Annual Average Wages based on Age Group') +
theme_bw() +
theme(axis.ticks.y = element_blank()) +
scale_fill_manual(values = c("TRUE" = "lightblue", "FALSE" = "lightpink"))
p
```
The output gives me the sum of wages based on the different age group.

] | There are a number of issues with your code, first, and the cause of the error message you posted, is that it should be `AUTO_INCREMENT` and not `AUTOINCREMENT`.
Second you need to specify the column you insert values into, i.e. `query = 'INSERT INTO data (content) VALUES (%s)'`
Third you should insert the list using `cursor.executemany(query, values)` where each row corresponds to a tuple containing the value since `cursor.execute()` cannot insert multiple rows at once.
Fourth `readlines()` returns the newline character at the end of each line, which you probably do not want, so to read the file and insert them you could e.g. do ~:
```py
query = 'INSERT INTO data (content) VALUES (%s)'
with open('test.txt', 'rt') as file:
values = [(value,) for value in file.read().splitlines()]
cursor.executemany(query, values)
``` | The error you show means that you want to insert your data in the table `file` which doesn't exist. You've created a table `data`. When you initialize `query`, do `query = 'INSERT INTO data VALUES (%s)'` instead. |

] | As a single-word-request, there might not be a perfect word that specifies "giving in to an authority".
More general words include
If the connotation is that the person doesn't want to do it but is doing it out of fear of reprecussions:
* *Impressionable*
* *Meek*
* *Weak-willed*
If the connotation is that the person is doing it because they have an agreement with the authority figure:
* *Corrupt*
* A *lackey* or *servant*
In your example, though you specify that the person has no weight on her conscience by her action of doing as the authority figure wants, which points to someone who isn't meek, but is more cold-hearted or unfeeling. In such context you might want to be more descriptive than a single word and specify why the person has no weight on her conscience.
"She left the house [...] and, out of pure **selfishness**, had no weight on her conscience because the repercussions of acting against the mother would have far outweighed any feeling of good-doing that helping Madeleine could have given her." | Maybe...

So if you can set `parallel="true"`. Please note that there is nothing to do with the nested `<sequential>` element, because the tasks inside `<sequential>` are still executed sequentially; by setting `parallel` parameter, you tell `<for>` tasks to execute multiple `<sequential>`s at the same time -- how many? It depends on the number of elements in your list, as well as the value of `threadCount`.
Please check
<http://ant-contrib.sourceforge.net/tasks/tasks/for.html>
to see all the parameters.

And for `<foreach>` task, it executes the specified target for each element in your list, or each file in the nested fileset. You can also use `parallel` property to make the execution parallel.

```
void get_bin(int *dst, intmax_t x);

Where `dst` is the resulting array (with `1`s and `0`s), and `x` is the decimal number.
For example:
C89 version:
```
#include <limits.h>
void get_bin(int *dst, int x)
{
int i;
for (i = sizeof x * CHAR_BIT - 1; i >= 0; --i)

{
for (intmax_t i = sizeof x * CHAR_BIT - 1; i >= 0; --i)
*dst++ = x >> i & 1;
}

It works as follow: we run through the binary representation of `x`, from left to right. The expression `(sizeof x * CHAR_BIT - 1)` give the number of bits of `x` - 1. Then, we get the value of each bit (`*dst++ = x >> i & 1`), and push it into the array.

return n % 2 + 10 * dec2bin(n / 2);

```
The max number that it can represent is 1023 (1111111111 in binary) because of *int* data type limit, but you can substitute *int* for *long long* data type to increase the range. Then, you can store the return value to array like this:

``` | As far as i know there is no such function in any C library. But here's a recursive function that returns a binary representation of a decimal number as int:
```
int dec2bin(int n)
{
if(n == 0) return 0;
return n % 2 + 10 * dec2bin(n / 2);
}
```
The max number that it can represent is 1023 (1111111111 in binary) because of *int* data type limit, but you can substitute *int* for *long long* data type to increase the range. Then, you can store the return value to array like this:
```
int array[100], i = 0;
int n = dec2bin(some_number);
do{
array[i] = n % 10;
n /= 10;
i++;
}while(n > 10)

] | You did not define what is a decimal number for you. I am guessing it is character representation (e.g. in ASCII) of that number.
Notice that numbers are just numbers. Binary or decimal numbers do not exist, but a given number may have a binary, and a decimal, representation. Numbers are not made of digits!
Then you probably want [sscanf(3)](http://www.kernel.org/doc/man-pages/online/pages/man3/scanf.3.html) or [strtol(3)](http://www.kernel.org/doc/man-pages/online/pages/man3/strtol.3.html) pr `atoi` to convert a string to an integer (e.g. an `int` or a `long`), and [snprintf(3)](http://www.kernel.org/doc/man-pages/online/pages/man3/sprintf.3.html) to convert an integer to a string.
If you want to convert a number to a binary string (with only `0` or `1` `char`-s in it) you need to code that conversion by yourself. To convert a binary string to some `long` use `strtol`. | If it helps you can convert any decimal to binary using bitset library, for example:
```
#include <iostream>
#include <bits/stdc++.h>
using namespace std;
int main(){
int decimal = 20;
bitset<5> binary20(decimal);
cout << binary20 << endl;
return 0;
}
```
So, you have an output like **10100**. Bitsets also have a "**toString()**" method for any purpose. |

**index.php** will have the form as you've shown above and will post to urlCreator.php.
**form.php** can be deleted as it is not needed anymore, the magic will happen in the urlCreator.php file.
**urlCreator.php** (NEW) will have code in it like so:
```
<?php
// urlCreator.php will get variables passed to it from index.php
// Now create the url using the passed variables
$url = "http://briandempsey.org.uk/Newstool/form.php?title=" . $_GET['title'] . "&color=" . $_GET['color'] . "&Articlecontent=" . $_GET['Articlecontent'] //and so on to build the whole url

The logic here is to first eliminate duplicate objects, then count the remaining IDs. The `NOT IN` subquery represents objects that have a matching object with a smaller ID. The subquery joins the parameters of two objects t1 and t2, then counts how many parameters matched for each t1/t2 pair. If the number of matching parameters is the same as the number of parameters in t1 and in t2, then t2 and t1 are matches and we should exclude t1 from the resultset.
```
DECLARE @tab TABLE (ID int, parameter varchar(2));
INSERT INTO @tab
SELECT 1, 'A' UNION ALL
SELECT 1, 'B' UNION ALL
SELECT 2, 'A' UNION ALL
SELECT 3, 'A' UNION ALL

As for objects with 0 parameters, it depends on how they're stored, but generally, you'd just need to add one to the answer above if there are any objects with 0 parameters. | There is no foolproof way to do this in SQL Server 2000, with the conditions specified, but the following will work for most situations and it will warn you if it won't work.
Given table, "**tbl**":
```
ID Parameter
1 A
1 B
2 A
3 A
3 B
4 A
4 NULL
5 C
5 D
6 NULL
```
.
Create this function:
```
CREATE FUNCTION MakeParameterListFor_tblID (@ID INT)
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE
@ParameterList VARCHAR(8000),
@ListLen INT
SET
@ParameterList = ''
SELECT
@ParameterList = @ParameterList + COALESCE (Parameter, '*null*') + ', '
FROM
tbl
WHERE
ID = @ID
ORDER BY
Parameter
SET @ListLen = LEN (@ParameterList)
IF @ListLen > 7800 -- 7800 is a SWAG.
SET @ParameterList = '*Caution: overflow!*' + @ParameterList
ELSE
SET @ParameterList = LEFT (@ParameterList, @ListLen-1) -- Kill trailing comma.
RETURN @ParameterList

.
Then this query:
```
SELECT

The logic here is to first eliminate duplicate objects, then count the remaining IDs. The `NOT IN` subquery represents objects that have a matching object with a smaller ID. The subquery joins the parameters of two objects t1 and t2, then counts how many parameters matched for each t1/t2 pair. If the number of matching parameters is the same as the number of parameters in t1 and in t2, then t2 and t1 are matches and we should exclude t1 from the resultset.

My wife and I are both monolingual Brits, living Britain, with a four-month old daughter. It seems a shame to waste this early stage (or perhaps the near future stage) when children are able to absorb language skills so quickly. Is there a gentle way to introduce some foreign language skills to our daughter now that would help her to enjoy a greater aptitude for learning languages later in life? I don't expect that our daughter will be fully bilingual, but could there be something in between raising a bilingual kid and not bothering at all? Foreign babysitter?

] | I'd recommend the foreign babysitter option. You'll want her to come on a regular basis, several hours a week at least, and you'll want her to speak to the child exclusively or almost exclusively in her own language. Make it clear that you want her just to speak the language, and not to attempt to teach it to the child; children don't learn languages natively the way they learn them in classrooms later on.
The child will probably speak back to her in English, and that's okay. She'll still learn to hear the sounds, which it more than half the battle of being able to speak them later on.
Perhaps more importantly, she'll learn at a fundamental level about the difference between meanings and words, since different languages use different words for the same meaning. This is thought to provide mental flexibility which can be highly useful even if she never actually learns a foreign language to a functional level. | Congratulation, you will give a precious gift to your child.
Children of that age learn by listening, **only by listening**. Before reaching 7 years old their acoustic filters are not fixed by one particular language yet. The *gentle way*, in your situation, is a **foreign nanny**, **movies or tv programs** plus **listening to music** in that second language you want your child to learn.

] | Congratulation, you will give a precious gift to your child.
Children of that age learn by listening, **only by listening**. Before reaching 7 years old their acoustic filters are not fixed by one particular language yet. The *gentle way*, in your situation, is a **foreign nanny**, **movies or tv programs** plus **listening to music** in that second language you want your child to learn.

I don't know how it worked out long term for them - hopefully fine!

The nursery linguistics expert talked to us about non-English mother-tongue children and gave us her opinion that confirms what some of the other answers say.

She also told us that to gain fluency, the child should be exposed to the 2nd language for at least 40 hours per week.
My partner and I achieved this by making German our house language - even though mine is a bit poor. I was dubious about the benefit I was bringing with my German, but it seemed to help. My daughter now corrects my German!
Again as others say, songs, audio books and TV are all useful and helped us achieve that 40 hour mark.
For me, it was clear that my partner's mother tongue was the 2nd language of choice (in fact it is competing to be the 1st language) but for you as monolingual people, I would recommend taking the plunge yourselves and learning a second language too. You could find a lot of synergies in the efforts you are making for your child - you could read books for her in that language yourself, you could go along to foreign-language play groups and actually converse in that language yourselves with the adults there, you could go on holiday to that country and actually get by with the locals etc etc.

`value` can be any data-type, and Karate will write the bytes (or plain-text) out. There is no built-in support for any other format.
Here is an [example](https://github.com/intuit/karate/blob/master/karate-demo/src/test/java/demo/embed/embed-pdf.js).
EDIT: for others coming across this answer in the future the right thing to do is:
1. don't write files in the first place, you never need to do this, and this question is typically asked by inexperienced folks who for some reason think that the only way to "save" a response before validation is to write it to a file. No, please don't waste your time - and please just `match` against the `response`. You can save it (or parts of it) to variables while you make other HTTP requests. And do not write your tests so that scenarios (or features) depend on other scenarios, this is a [very bad practice](https://stackoverflow.com/a/46080568/143475). Also note that by default, Karate will dump all HTTP requests and responses in the log file (typically in `target/karate.log`) and also in the HTML report.
2. see if `karate.write()` works for you as per this answer
3. write a custom Java (or JS function that uses the JVM) to do what you want using [Java interop](https://github.com/intuit/karate#calling-java)

42,038 | I'm new to cryptography. While reading about symmetric key encryption, it was mentioned that it requires secret key exchange so that 2 parties can decrypt the ciphertext.
Now, using some encryption software like GPG, we can use symmetric encryption by `gpg --symmetric abc.txt`
It asks for password there.
Is the key generated using the password?
Can I actually see the secret key if I want to?
Symmetric key cryptography requires secure key exchange. But in real world the 'key' itself is not exchanged right? Instead the password should be securely exchanged right?
Also, is the key actually present in the ciphertext & unlocked by the password or is it generated on-the-spot when we give our password?

Yes. In this sort of scenario, the password is run through a key derivation function ([KDF](http://en.wikipedia.org/wiki/Key_derivation_function)) such as [PBKDF2](http://en.wikipedia.org/wiki/PBKDF2) to generate the key.
>
> Can I actually see the secret key if I want to?

>

AFAIK, the symmetric key in this case is not stored anywhere. Instead, the key is derived from the password each and every time you want to encrypt or decrypt something. If you really want to obtain the key, you can run your password through the KDF assuming you know the salt and iteration count.

This is quite a complex topic. In the case of GPG in symmetric mode, the key is not transferred by any means. Knowledge of the password is required to decrypt the encrypted data.
If you want to "share" the encrypted data with another entity, you usually make use of a [hybrid cryptosystem](http://en.wikipedia.org/wiki/Hybrid_cryptosystem). In the case of GPG, you will be encrypting the file *without* the `--symmetric` flag. What this does is encrypt the data with a **randomly generated** symmetric key. This randomly generated key is then encrypted with the *public* key of your target (the recipient in GPG-speak). The encrypted symmetric key is appended with the encrypted blob and sent to your target. Your target will then decrypt the encrypted symmetric key with his *private* key and use the decrypted symmetric key to decrypt the encrypted blob. | 1) Yes, --symmetric does derive a 128bit key from the password and a salt prepended to the encrypted output. It uses a function called Password Based Key Derivation Function 2 (PBKDF2) to do this. Infact, this is also how gpg encrypts the private key so that only your passphrase can use the file.
2) Well, you could run the password and salt yourself through the function to generate the key.
3) In real life asymmetric cryptography is usually used to exchange symmetric keys generated for that session. Then those symmetric keys are used for the actual encryption of the data/message. |

public CampaignSpecification DateBetween(DateTime from, date to);
public CampaignSpecification Year(DateTime year);

61,912,299 | I'm designing an app for the company I work for that uses a basic y=mx+c (or y=mx+b if you're from the US) to take 2 calibrated values and 2 input values to output scale and offset values. The app takes a users input from a total of 4 text fields, and then uses a few formulas to output into a text view. My problem is that the input values need to be 'Doubles' for use in the formulas (Divisor, m\_FinalScale, m\_FinalOffset) whereas the values that the user inputs are 'Strings?' because they are from a text field. How could I go about unwrapping and converting those optional strings to then use?
```
override func viewDidLoad() {
super.viewDidLoad()
Cal1Field.delegate = self
Cal2Field.delegate = self
Input1Field.delegate = self
Input2Field.delegate = self
}
//Actions
@IBAction func CalibrateTapped(_ sender: Any) {
var Divisor = 0.0, m_FinalScale = 0.0, m_FinalOffset = 0.0
// this is what the formulas are
Divisor = Input2Field.text - Input1Field.text
m_FinalScale = (Cal2Field.text - Cal1Field.text)/Divisor
m_FinalOffset = Cal1Field.text - (m_FinalScale*Input1Field.text)
}

```
let input1 = input2Field.text.flatMap(Double.init)
let input2 = input2Field.text.flatMap(Double.init)
let cal1 = cal2Field.text.flatMap(Double.init)
let cal2 = cal2Field.text.flatMap(Double.init)

If you want to avoid the code duplication, you can add an extension over `UITextField`:
```swift
extension UITextfield {
var doubleValue: Double? { text.flatMap(Double.init) }

, which you can later use like this:
```swift
let input1 = input2Field.doubleValue
let input2 = input2Field.doubleValue
let cal1 = cal2Field.text.doubleValue
let cal2 = cal2Field.text.doubleValue

A couple of notes here:
1. I renamed the text fields to start with a lowercase letter, to follow the Swift [naming conventions](https://swift.org/documentation/api-design-guidelines/#follow-case-conventions).
2. `input1`, `input2`, `cal1`, `cal2` are optionals, it your call what to do if some are nil (e.g. the user entered invalid values). | You can use this extension
```
extension String {
var convertItToDouble: Double? {

Your bank account is an asset to you, but a liability to your bank. That makes for a third issue, namely perspective. | "Debits'" and "Credits" are terms used in double-entry bookkeeping. Each transaction is entered in two different places to be able to double-check accuracy. The total debits and total credits being equal is what makes the balance sheet balance.
For explaining debits and credits, wikiversity has a good example using eggs that I found helpful as a student.
Debits and Credits
When a financial transaction is recorded, the Debits (Dr) and Credits (Cr) need to balance in order to keep the accounts in balance.
An easy rule to remember is, "Debit the Asset that Increases"
For example, if you want to practice accounting for cooking a simple breakfast, you might proceed as follows:
* Dr the frying pan 2 egg yolks
* Dr the frying pan 2 egg whites
* Dr the trash basket 2 egg shells
o Cr the carton of eggs 2 whole eggs
To record breaking the eggs and putting the eggs in the frying pan
In this transaction, an asset, (the egg) is split into parts and some of the asset goes in the pan and some in the trash. A Debit (Dr) is used to show that the assets in the pan and the trash both increase. A balancing Credit (Cr) is used to show that the amount of assets (whole eggs) in the egg carton has decreased.
This transaction is in balance because the total Credits equal the total Debits. Everything that is covered by the Debits (yolk, white and shell) is also covered by the Credits (one whole egg) |

3,919 | You are a railroad entrepreneur in the 19th-century United States when trains become popular because they are the most efficient means of transporting large volumes of materials by land. There is a national need for railroad tracks from the east coast through some recently colonized lands in the west.
To accommodate this need, the U.S. government is going to levy a tax to subsidize railroads. They have promised to pay money to your railroad company for each mile of track laid. Since laying tracks in hilly and mountainous regions is more expensive than laying tracks in flat land, they adjust the amount they give accordingly. That is, the government will pay
* $5,000 per mile of track laid in flat land
* $12,500 per mile of track laid in hilly land
* $20,000 per mile of track laid in mountains.
Of course, this plan does not accurately reflect how much it actually costs to lay tracks.
You have hired some cartographers to draw relief maps of the regions where you will be laying track to analyze the elevation. Here is one such map:
```
S12321
121234
348E96
```
Each digit represents one square mile of land. `S` is the starting point, `E` is the ending point. Each number represents the intensity of the elevation changes in that region.
* Land numbered 1-3 constitutes flat land.
* Land numbered 4-6 constitutes hilly land.
* Land numbered 7-9 constitutes a mountain range.
You have, through years of experience building railroad tracks, assessed that the cost of track building (in dollars) satisfies this formula:
```
Cost_Per_Mile = 5000 + (1500 * (Elevation_Rating - 1))
```
That means building on certain elevation gradients will cost you more money than the government gives, sometimes it will be profitable, and sometimes you will just break even.
For example, a mile of track on an elevation gradient of 3 costs $8,000 to build, but you only get paid $5,000 for it, so you lose $3000. In contrast, building a mile of track on an elevation gradient of 7 costs $14,000, but you get paid $20,000 for it: a $6,000 profit!
Here is an example map, as well as two different possible paths.
```
S29 S#9 S##
134 1#4 1##

The first track costs $30,000 dollars to construct, but the government pays you $30,000 for it. You make no profit from this track.
On the other hand, the second costs $56,500 to build, but you get paid $62,500 for it. You profit $6,000 from this track.
**Your goal:** given a relief map, find the most profitable (or perhaps merely the least expensive) path from the start to the end. If multiple paths tie, any one of them is an acceptable solution.
Program Details
===============
You are given text input separated with a rectangular map of numbers and one start and end point. Each number will be an integer inclusively between 1 and 9. Other than that, the input may be provided however you like, within reason.
The output should be in the same format as the input, with the numbers where track has been built replaced by a hash (`#`). Because of arbitrary regulations imposed by some capricious politicians, tracks can only go in horizontal or vertical paths. In other words, you can't backtrack or go diagonally.
The program should be able to solve in a reasonable amount of time (i.e. <10 minutes) for maps up to 6 rows and 6 columns.
This is a **code golf** challenge, so the shortest program wins.
I have an [example (non-golfed) implementation](http://jsbin.com/osugoz/17/edit#preview).

3,919 | You are a railroad entrepreneur in the 19th-century United States when trains become popular because they are the most efficient means of transporting large volumes of materials by land. There is a national need for railroad tracks from the east coast through some recently colonized lands in the west.
To accommodate this need, the U.S. government is going to levy a tax to subsidize railroads. They have promised to pay money to your railroad company for each mile of track laid. Since laying tracks in hilly and mountainous regions is more expensive than laying tracks in flat land, they adjust the amount they give accordingly. That is, the government will pay
* $5,000 per mile of track laid in flat land
* $12,500 per mile of track laid in hilly land
* $20,000 per mile of track laid in mountains.
Of course, this plan does not accurately reflect how much it actually costs to lay tracks.
You have hired some cartographers to draw relief maps of the regions where you will be laying track to analyze the elevation. Here is one such map:
```
S12321
121234
348E96
```
Each digit represents one square mile of land. `S` is the starting point, `E` is the ending point. Each number represents the intensity of the elevation changes in that region.
* Land numbered 1-3 constitutes flat land.
* Land numbered 4-6 constitutes hilly land.
* Land numbered 7-9 constitutes a mountain range.
You have, through years of experience building railroad tracks, assessed that the cost of track building (in dollars) satisfies this formula:
```
Cost_Per_Mile = 5000 + (1500 * (Elevation_Rating - 1))
```
That means building on certain elevation gradients will cost you more money than the government gives, sometimes it will be profitable, and sometimes you will just break even.
For example, a mile of track on an elevation gradient of 3 costs $8,000 to build, but you only get paid $5,000 for it, so you lose $3000. In contrast, building a mile of track on an elevation gradient of 7 costs $14,000, but you get paid $20,000 for it: a $6,000 profit!
Here is an example map, as well as two different possible paths.

**karoberts** proposes a good way if *we need a software solution to our problem* (JCS citation, almost, isn't it? ))

] | $H\_i (CP^2 \setminus RP^2)\cong H^{4-i}(CP^2, RP^2)$ by Poincare-Alexander-Lefschetz duality (Bredon, Topology and Geometry, Theorem 8.3 on p. 351). The latter can be computed using the long exact sequence. $H^4 = Z$, $H^0=H^1=0$ is immediate. The piece
$$0 \to H^2 (CP^2,RP^2) \to H^2 (CP^2) \to H^2 (RP^2) \to H^3 (CP^2 , RP^2) \to 0$$
needs an extra argument. The map $Z=H^2 (CP^2 ) \to H^2 (RP^2)=Z/2$ is onto because the tautological complex line bundle restricts to the complexification of the real tautological line bundle, whose first Chern class generates $H^2 (RP^2)$. Thus $H\_2 (CP^2 \setminus RP^2)=Z$ and $H\_1 (CP^2 \setminus RP^2)=0$.
Because the first map in the above sequence is multiplication by $2$ (after identification with $Z$), it follows that the inclusion $H\_2 (CP^2 \setminus RP^2)\to H\_2 (CP^2)$ takes a generator to twice a generator. A generator of $H\_2 (CP^2-RP^2)$ can be represented by an embedded sphere as follows. Take a quadric $Q \subset CP^2$ without real point, for example the one defined by the homogeneous equation $z\_{0}^{2}+z\_{1}^{2}+z\_{2}^{2}=0$. By the degree genus formula, $Q$ has genus $0$, hence is a sphere. It lies in $CP^2 - RP^2$, and because its fundamental class is twice a generator of $H\_2 (CP^2)$, it must represent a generator of $H\_2 (CP^2 - RP^2)$.
In fact, $CP^2-RP^2$ is diffeomorphic to the normal bundle of $Q$, see Tom's comment below. | There is [a beautiful (and elementary) paper by V. I. Arnold,](http://dl.dropbox.com/u/5188175/arnoldquadric.pdf) which discusses this and generalizations. |

All these items are 1:N or N:N relations in SqlServer, and we are searching for multiple items AND we want to know 'how much match' you have.

Hi, I am an amateur who is making a historical map.
As you can see in the picture, I have a problem using qgis2web.
The first picture is a normal scene output from QGIS version 3.8.
The second picture was taken from qgis2web with a Mapbox. Transparency is nice, but the text in the labels is terrible.
The third picture was taken from qgis2web with openlayers. Transparency, text in labels, it's all a mess.
I tested [this site](http://eastmaps.com/2019/09/10/%ED%85%8C%EC%8A%A4%ED%8A%B8/) a year ago, but it was fine at the time. What should I do ? It's too hard... | 2020/02/10 | [

"https://gis.stackexchange.com/users/157873/"
] | I finally got the answer!
I set the opacity of the color of the layer.
But the opacity of the layer rendering was 100%.
When I lowered the opacity of layer rendering, not a single symbol, the qgis2web worked successfully.
People who are struggling with this, I hope it helps! | Open the HTML file in notepad and scroll down the code until you get to the layer you want the transparency to change. it should look something like:
function style\_20YearFlood\_2\_0() {
```
return {
pane: 'pane_20YearFlood_2',
opacity: 1,
color: 'rgba(35,35,35,1.0)',
dashArray: '',
lineCap: 'butt',
lineJoin: 'miter',
weight: 1.0,
fill: true,
fillOpacity: 1,
fillColor: 'rgba(255,158,23,1.0)',
interactive: false,
```
20 year flood in my case was the layer I wanted to be partly transparent.Then just change the "fillOpacity:" to whatever you want. I chose 50% so it now looks like:
function style\_20YearFlood\_2\_0() {
```
return {
pane: 'pane_20YearFlood_2',
opacity: 0.5,
color: 'rgba(35,35,35,1.0)',
dashArray: '',
lineCap: 'butt',
lineJoin: 'miter',
weight: 1.0,
fill: true,
fillOpacity: 0.5,
fillColor: 'rgba(255,158,23,1.0)',
interactive: false,
```
Save the file, and then open the html in your browser. It should now be transparent to whatever % you indicated.
Hope this helps!

$food += 11;
}
for($row = 0;$row<=19;$row++){
echo $col_num[$row].$col_food[$row]."<br>";

**Here is the code I attempted to make a function with an array**
```

$pos = 0;
$food = 1;

for($rows = 0;$rows<=19;$rows++){
echo $col[$rows]."<br>";
}
}
getcoleachrow($col_num, $num);
getcoleachrow($col_food, $food);

] | The problem is that $html is out of scope. You need to pass $html into the getcoleachrow function, e.g.:
```
function getcoleachrow($col = array(), $value, $html){
for($value=$value;$value<220;$value+=11){
array_push($col, $html->find('td', $value)->plaintext);
}
for($rows = 0;$rows<=19;$rows++){
echo $col[$rows]."<br>";
}
}
getcoleachrow($col_num, $num, $html);
```
And yes, I agree with Marc B - a good place to look for more information on the subject is here: <http://php.net/manual/en/language.variables.scope.php> | You need to add `global $html;` inside the function...
```
function getcoleachrow($col = array(), $value){
global $html;

45,886,682 | How can one store a variadic template to enable reuse in later instances?
Code Example:
```
template <typename T, typename ...initArgs>
Collection_class {
std::vector<T> storage;
initArgs ...constructorArguments;
Collection_class<T, initArgs>(initArgs... args) {
constuctorArguments = args;
}
void CreateInstance() {
storage.emplace(constructorArguments);
}
}
```
Is there any way you can store a varidic template as an object/collection that would enable you to reuse it, in this case for a constructor?
I have seen people storing the arguments in a `std::tuple` however I am unsure how I could use that in a generic class.

] | You can acheive this by storing the arguments in a tuple:
```
#include <vector>
#include <tuple>
template<typename T, int index, typename ...initArgs>
struct VectorInit {
static void append(std::vector<T> & dst,
std::tuple<initArgs...> const& args) {
VectorInit<T, index-1, initArgs...>::append(dst, args);
dst.emplace_back(std::get<index>(args));
}
};
template<typename T, typename ...initArgs>
struct VectorInit<T, 0, initArgs...> {
static void append(std::vector<T> & dst,
std::tuple<initArgs...> const& args) {
dst.emplace_back(std::get<0>(args));
}
};
template <typename T, typename ...initArgs>
class Collection_class {
std::vector<T> storage;
std::tuple<initArgs...> init_args;
public:
Collection_class(initArgs... args)
: init_args(args...) {
}
void CreateInstance() {
storage.reserve(sizeof...(initArgs));
VectorInit<T, sizeof...(initArgs)-1, initArgs...>::append(storage, init_args);
}
};
int main() {
Collection_class<double, float, int> test(1.2f, 4);
test.CreateInstance();
}
```
**Edit:** `CreateInstance()` can be implemented by recursively peeling each element of the tuple. I did it from `sizeof...(args)` to 0, which is why the recursion happens before the `emplace_back`.
There's probably a neater way to do this with parameter pack expansions, but this is a simple enough case that I find the template specialization route to be simpler. | Why don't you simply let the `std::vector` handle that:
```
template <typename T>
Collection_class {
std::vector<T> storage;
public:
Collection_class<T>(std::initializer_list<T> initargs) : storage(initargs) {
}
}
```
Note the deferred `CreateInstance()` won't be necessary anymore.
---
The `initArgs` variadic template parameters would let your `Collection_class` instantiations *"explode"* for any possible combination of parameters. That's certainly not what you actually want. |
